      Wall Street is buzzing about Elon Musk merging Tesla with SpaceX. Analysts call it the holy grail. But this wouldn't be the first time Musk folded one of his companies into another. He did it in twenty sixteen. And the story of how that went should be required reading before anyone votes on the next one.

      This is Tesorb Signal and this is Lena Ruiz. Today, the SolarCity playbook. We'll revisit the deal where Tesla bought a company run by Musk's cousins. The seven year court fight that followed. And what the aftermath teaches us about the merger talk swirling right now.

      Rewind to twenty sixteen. SolarCity was the biggest residential solar installer in America, founded by Musk's cousins, Lyndon and Peter Rive. Musk was its chairman and its largest shareholder. He was also, of course, the CEO of Tesla. That summer, Tesla offered to buy SolarCity for two point six billion dollars. Paid in Tesla stock.

      On paper, the logic sang. Solar panels on your roof. A battery in your garage. A car in the driveway. One integrated sustainable energy company. Musk unveiled a gorgeous new Solar Roof to seal the vision, and shareholders of both companies voted yes.

      One more wrinkle made it feel like family business. Musk had personally poured money into SolarCity to keep it afloat, and even SpaceX had bought the solar company's bonds. By twenty sixteen, the fates of the chairman, his cousins, and three of his companies were braided into a single knot. Untangling who was rescuing whom took a courtroom.

      What the pitch played down was SolarCity's condition. The company was carrying more than three billion dollars of debt, burning cash, and cutting a fifth of its workforce that very year. Critics had a blunter name for the acquisition. A bailout. Of the chairman's own investment, paid for with Tesla shareholders' stock.

      Tesla shareholders sued, seeking up to thirteen billion dollars from Musk personally. Their claim was simple. Musk sat on both sides of the deal and steered his own board into rescuing his cousins' company. The case took years to reach trial. In twenty twenty-two, a Delaware judge ruled. Musk won.

      The legal standard matters for what comes next, so a quick translation. If a friend who ran two lemonade stands used one to buy the other, at a price he helped shape, you'd raise an eyebrow. Delaware law raises the same eyebrow. It demands the deal prove itself entirely fair, the toughest test on the books. Musk's deal passed it.

      But read the ruling closely, because it isn't a clean bill of health. The judge wrote that Musk was more involved in the process than a conflicted fiduciary should be. The court still found the price fair and the board's review meaningful, and Delaware's highest court later agreed. Legally, the deal was declared entirely fair.

      The trial produced one detail worth remembering. Testimony revealed that the beautiful Solar Roof tiles at that twenty sixteen unveiling, the ones that sold the whole vision, weren't actually functional. The product that justified the merger, on the night it mattered most, was a prop.

      Now for the other verdict. The one the market delivered. Within roughly a year of the deal, Tesla's solar installations had fallen by more than forty percent. The market leader Tesla bought slid to a sliver of the residential solar business. The cousins left within a year. And after Musk won the lawsuit, Tesla quietly stopped reporting solar numbers at all.

      Tesla had projected the combined company would install solar at a blistering pace. Instead, deployments kept sliding for years, until they were a fraction of what SolarCity had managed on its own before the deal. The integrated sustainable energy company still sells cars and batteries. The solar piece became a footnote.

      To be fair, the acquisition wasn't a total loss. The energy division that grew out of it eventually produced the Megapack, the grid battery business we covered in episode thirty-five, which is now one of Tesla's healthiest product lines. Something valuable did emerge. It just wasn't the thing shareholders were sold.

      Which brings us back to twenty twenty-six. SpaceX's own president has hinted that combining with Tesla might make Musk's life easier. Analysts call a merger inevitable. The companies already share board members, engineers, and billions in transactions, the tangle we mapped in episode twenty-one. The integrated vision pitch is warming up again, at a scale hundreds of times larger.

      And this time the pattern has already started rhyming. A merger of Musk companies, blessed by a friendly vote. A dazzling product reveal to carry the story. We covered the one company thesis back in episode sixteen. SolarCity is what that thesis looks like after ten years of weather.

      There's one difference of scale worth naming. SolarCity was a two point six billion dollar bite. A Tesla and SpaceX combination would be the largest merger in the history of markets, joining two of the most valuable companies alive. The eyebrow Delaware raised last time would become a national spectacle this time.

      Hold those two verdicts side by side. The legal question, was the deal fair, was eventually answered yes. The business question, did the deal deliver what shareholders were promised, was answered just as clearly. No. Both answers are true at once. That's the entire lesson.

      When the next merger pitch arrives, wrapped in an integrated vision and a beautiful reveal, remember that courtroom fairness and shareholder value are two different tests. SolarCity passed the first and failed the second. The pitch never tells you which one you're voting on. Only the following decade does.

        Four days after the biggest IPO in history, SpaceX went shopping. It agreed to buy Cursor, an AI coding company, for sixty billion dollars. It didn't spend a dime of cash. And by the time the ink dried, Cursor's most valuable asset had already been poured into Grok.

        This is Tesorb Signal and this is Lena Ruiz. Today, the sixty billion dollar deal where the goods moved before the money. We'll walk through how the Cursor acquisition actually works. Then the new Grok model that was quietly trained on Cursor's data. And what the sequencing tells us about how the Musk ecosystem really operates.

        If you don't live in the software world, a quick primer. Cursor is the tool that made AI coding mainstream. It's an editor where developers write software side by side with an AI assistant. In about four years it went from a student project to one of the fastest growing products in tech history, used inside a huge share of America's biggest companies.

        Let's rewind to April. Back in episode fifteen, we covered a strange arrangement. SpaceX didn't buy Cursor outright. It bought an option. Either acquire the company later for sixty billion dollars, or walk away and pay roughly ten billion for the partnership. And part of that walk-away fee wasn't even money. It was computing time.

        Then came June. SpaceX went public on June twelfth in the largest IPO ever. The stock surged. Just four trading days later, SpaceX exercised its option and signed a binding agreement to buy Cursor. The price is paid entirely in newly minted SpaceX stock. Not a dollar of cash changes hands. The deal is expected to close later this year.

        Pause on that mechanism, because it's genuinely new. The stock jumped so much in its first days of trading that the gains alone could have covered the purchase several times over. SpaceX turned four days of market enthusiasm into ownership of one of the fastest growing software companies on Earth. Paper became product.

        It also sets a template. SpaceX now has a publicly traded share price, and that paper can buy real things. When your stock carries a premium, every acquisition comes at a discount. The Musk premium we covered in episode twenty-nine isn't just a valuation quirk anymore. It's a checkbook.

        Now for the part that got far less attention. In late June, Musk announced a new model called Grok four point five. Buried in his post was a detail worth reading twice. The model, he said, was trained with Cursor data added in. It's in private beta inside SpaceX and Tesla, and Musk claims it rivals the best models from Anthropic.

        Follow the timeline. The acquisition hasn't closed. Cursor is, legally, still an independent company. But its data, the record of millions of developers writing real code with AI assistance, is already inside Grok's training runs. The value SpaceX is paying sixty billion dollars for started flowing months before the purchase completes.

        Why does that data matter so much? Because usage produces something nobody can buy off a shelf. Millions of real programming sessions. What developers asked for. What the AI suggested. What got accepted, and what got thrown back. For training a coding model, that feedback trail is gold, and Cursor holds the richest supply of it on Earth.

        To be fair, none of this appears improper. The April agreement was explicitly a partnership, and sharing was the point. Cursor got what it publicly said it needed, which is massive computing power for its own models. Its founders and investors get stock in one of the most valuable companies on Earth. Both sides signed up for exactly this.

        But the sequencing still tells you something important about how this ecosystem works. Remember episode twenty-one, Tesla's best customer, where we traced how money and resources flow between Musk companies long before the paperwork catches up? This is the same pattern at a grander scale. Integration first. Ownership later.

        There's a governance wrinkle too. At least one major venture firm holds large stakes on both sides of this deal, in SpaceX and in Cursor. When the same investors sit on both sides of the table, the price isn't really negotiated between strangers. It's agreed within a family. That's worth remembering when you hear the headline number.

        And the price itself deserves a squint. Cursor is a four year old company that crossed a billion dollars in yearly revenue only last fall. Sixty billion values it at many, many times that. The bet isn't on today's business. It's that owning the tool developers actually use, and the data trail they leave behind, is the scarcest asset in AI.

        There's a competitive logic to the timing as well. The most trusted coding models today come from Anthropic and OpenAI, and Grok has chased them from behind. Buying the place where developers actually work gives Musk something rivals can't easily copy. Distribution. Millions of programmers, already inside his product, feeding it every single day.

        So watch what got used, not what got signed. The contracts, the option, the stock mechanics, that's all choreography. The substance is that Cursor's data was training Grok while the market was still debating the price tag. In the Musk ecosystem, the assets merge long before the companies do.

        When you see the next Musk acquisition headline, skip the price and find the plumbing. Ask what's already flowing between the companies. That flow, not the announcement, is where the real deal lives. Sixty billion dollars bought SpaceX a company it was, in every way that matters, already using.

        That's the signal. I'm Lena Ruiz with the Tesorb Signal podcast. For more news about Tesla, SpaceX, and Elon Musk's companies, visit our website at tesorb.com.

          Tesla's car business had a rough year. Deliveries fell. Revenue declined for the first time in company history. But one Tesla product just posted record numbers. It isn't a car. It isn't a robot. It's the plug on the wall, and it now powers more than half of all fast charging in America.

          This is Tesorb Signal and this is Lena Ruiz. Today, the quiet empire Tesla built while everyone was watching the robots. We'll look at how big the Supercharger network actually became. How Tesla got every rival to surrender to its plug. And whether this is a real business or just a very expensive perk.

          Start with the scale. According to federal energy data, Tesla operates roughly fifty-two percent of all the DC fast charging ports in the United States. Every other network in the country, combined, makes up the other half. If you pull into a fast charger anywhere in America, it's basically a coin flip whether Tesla built it.

          And the network isn't just big. It's woven into the map. On major American interstates, a charger now sits roughly every fifty to seventy miles. That density is the whole product. Nobody plans a road trip around the second biggest network. Charging is a business where the map is the moat.

          It's worth remembering how unfashionable this bet once looked. Tesla started building Superchargers back in twenty twelve, when electric cars were a rounding error and every new charger was a money loser in an empty parking lot. Tesla built anyway, years ahead of demand. That head start is now more than a decade long, and it compounds.

          So how did one company end up owning half the country's fast charging? The short answer is that everyone else gave up. In twenty twenty-three, Ford broke ranks and adopted Tesla's charging plug. Then General Motors followed. Then Rivian, Hyundai, and eventually the parent company of Jeep and Dodge. One by one, the industry adopted Tesla's connector as the standard.

          Consider what that means in practice. A Ford or a GM electric vehicle now pulls into a Tesla station, plugs into Tesla hardware, and pays Tesla for the electricity. Tesla's competitors send their customers, and their customers' money, directly into Tesla's network. It's as if every gas station in America had quietly become an Exxon.

          A useful way to picture the arrangement is airports. Airlines compete ferociously with each other, but every one of them pays landing fees to whoever owns the runway. Tesla spent a decade pouring runways. Now Ford, GM, and Hyundai are the airlines, lining up to land.

          There's a reason they surrendered. Independent studies have ranked Superchargers as the most reliable fast chargers in the country. For years, broken chargers were the number one complaint of electric vehicle owners outside the Tesla world. The rivals didn't adopt Tesla's plug because they wanted to. They adopted it because their customers demanded it.

          And the hardware keeps moving. Tesla is rolling out its newest generation of chargers, roughly twice as fast as the ones they replace, plus even bigger units for the coming Semi trucks. It's also assembling charger stations inside the factory, so a new site drops into a parking lot in days instead of months. Speed of deployment has become a weapon of its own.

          So is this a real business? This is where the picture gets more complicated. Tesla folds charging revenue into its services segment, so we never see a clean number. What we do know is usage. Tesla reported about sixty million charging sessions last quarter, with the average stall used roughly nine times a day. That's utility company scale. Steady. Boring. Growing.

          But the honest picture cuts the other way too. Tesla's slice of the pie is shrinking. A few years ago it controlled the fast charging market with room to spare. New networks from rival automakers, and even Walmart, are now growing faster. Tesla's share will likely dip below the halfway mark sometime this year. Tesla traded exclusivity for volume, and the competition it invited is real.

          If this story feels familiar, it's the same pattern we found in episode thirty-five, on Tesla's energy storage business. The boring products are quietly becoming the dependable ones. And after episode fifty-two, where BYD took the global electric vehicle sales crown, Tesla needs dependable more than ever.

          Charging also plugs straight into Tesla's other quiet business. Every session sells electricity, and Tesla increasingly stores that electricity in its own giant batteries, buying power when it's cheap and selling it to drivers when they need it. The plug, the battery, and the grid are slowly becoming one machine.

          But charging matters for one more reason. Every robotaxi Tesla dreams of running, every delivery van and electric truck on its roadmap, needs somewhere to charge. The network isn't just a side business serving other people's cars. It's the foundation under everything Tesla says it wants to become. Autonomy is the headline. Electricity is the prerequisite.

          So zoom out from the plug for a second. Tesla spent more than a decade building charging infrastructure ahead of demand, at a scale nobody else would fund. That bet has now matured into the default fuel network for American electric cars. One that even Tesla's fiercest competitors pay to use, every single day.

          The Supercharger network is Tesla's quietest strategic asset. Not because it makes headlines, but because it makes everything else stickier. Cars change. Market share shifts. Infrastructure endures. While the robotaxi race and the robot demos dominate the news cycle, the most durable thing Tesla owns might be the humble plug.

          That's the signal. I'm Lena Ruiz with the Tesorb Signal podcast. For more news about Tesla, SpaceX, and Elon Musk's companies, visit our website at tesorb.com.

        • SpaceX and Google: The $920 Million Rent Check

          Google will pay SpaceX $920 million a month starting in October to rent AI computing capacity from the Colossus data centers in Memphis. The contract runs through June 2029.

            Google runs some of the largest data centers on the planet. It designs its own AI chips. It has spent twenty years building more computing power than almost any company alive. And starting this October, Google will pay Elon Musk nine hundred and twenty million dollars a month. To rent computers.

            This is Tesorb Signal and this is Lena Ruiz. Today, the rent check that says everything about the AI boom. We'll break down the Google deal itself. Then why the world's biggest infrastructure builder is renting from a rocket company. And finally, what this means for the SpaceX growth story now that the company is public.

            First, the deal. In early June, days before SpaceX went public, a regulatory filing revealed that Google agreed to pay SpaceX nine hundred and twenty million dollars a month for AI computing capacity. The contract runs from this October through June of twenty twenty-nine. Add it all up, and it's one of the largest computing agreements ever disclosed.

            Take a second with that monthly figure. It's nearly a billion dollars. Every month. For access to someone else's computers. Entire companies have been acquired for less than one month of this rent. And Google, of all companies, decided that writing this check was cheaper than waiting.

            What does Google get? Access to about one hundred and ten thousand Nvidia GPUs, plus the processors and memory around them, sitting in the data centers SpaceX built for its xAI division. The same Colossus machines in Memphis that we covered back in episode thirty-six. The ones running on Tesla batteries.

            It helps to remember what capacity physically means here. Buildings. Power lines. Cooling. Racks of chips that took years to source. Google isn't buying a service so much as reserving floor space in a machine that already exists. In a market where every chip is spoken for, existing beats planned.

            And the contract has teeth on both ends. If SpaceX can't deliver the promised chips by the end of September, Google can walk away immediately. After this year, either side can exit with ninety days notice. This isn't a marriage. It's a lease. A very, very large lease.

            So why is Google renting at all? In its own words, it needs bridge capacity. Demand for its Gemini business products has run ahead of even Google's expectations, and building new data centers takes years. SpaceX has capacity standing ready today. In the AI boom, speed beats ownership.

            There's a poetic loop in this arrangement too. Alphabet, Google's parent company, invested in SpaceX back in twenty fifteen, when the rocket maker was a scrappy private startup. More than a decade later, the company it once helped fund has grown into its landlord. The tenant used to hold the deed.

            And Google isn't the only tenant. A month earlier, Anthropic, one of xAI's most direct competitors, signed up for the entire capacity of the first Colossus data center. Sit with that arrangement for a second. Companies that compete head on with Grok are now paying to run their own models inside Elon Musk's buildings.

            If this sounds familiar, it should. Back in episode seventeen we called SpaceX the compute landlord, when the first hints emerged that it would rent its supercomputers to rivals. That thesis just graduated from theory to signed contracts. And the tenants are two of the biggest names in AI.

            Now, the honest picture. These contracts are real revenue against a very real problem. SpaceX's AI segment lost two and a half billion dollars in the first quarter, while its data center spending more than doubled. Deals like this one are exactly how that gap is supposed to close. In that sense, the landlord strategy is working precisely as designed.

            But read the fine print again. Google calls this bridge capacity. A bridge is temporary by definition. Google is building its own data centers as fast as it can pour concrete, and so is Anthropic. These tenants are renting because of a shortage, and both of them are working hard to end that shortage. The ninety day exit clause exists for a reason.

            There's also a circularity worth naming. Chip makers invest in AI labs. The labs sign giant computing deals with each other. One company's revenue is another company's spending, inside the same small circle. None of that makes the Google deal fake. It does mean the whole structure leans on AI demand continuing to outrun supply.

            One quiet question hangs over all of this. Every chip rented to Google is a chip that Grok isn't training on. SpaceX insists it has room for both. But when computing power is the scarcest resource in AI, leasing this much of your kitchen to the neighbors says something. Either about your own appetite, or about your need for the cash.

            So what does it actually mean when your rival pays your rent? It means you own something scarce. Right now, ready to use computing power is one of the scarcest assets on Earth, and SpaceX built a warehouse full of it. That's the strongest, most concrete revenue story in the entire SpaceX AI portfolio. Not chatbots. Not robots. Floor space and electricity.

            Landlords do incredibly well during a housing shortage. The question that should sit in the back of your mind is a simple one. What happens to the rent when the tenants finish building their own houses? SpaceX has until twenty twenty-nine to turn bridge customers into permanent ones. That's the deadline that matters more than the monthly check.

            Two markers will tell us how it's going. Whether SpaceX keeps landing new tenants at rates like this one. And whether the AI segment's losses actually start narrowing once the Google payments begin flowing in October. Watch the vacancy rate, not the press releases.

            That's the signal. I'm Lena Ruiz with the Tesorb Signal podcast. For more news about Tesla, SpaceX, and Elon Musk's companies, visit our website at tesorb.com.

              This week, the Wall Street Journal reported that SpaceX showed investors a secret AI phone. Elon Musk’s entire response was two words. Utterly false. The market’s response was louder. It erased more than fifty billion dollars of his net worth in a single afternoon.

              This is Tesorb Signal and this is Lena Ruiz. Today, the phone that may or may not exist. We’ll cover what the Journal actually reported. Why a flat denial sent the stock down instead of up. And what this strange week reveals about how the market prices Elon Musk’s promises.

              Let’s start with the report. On July first, the Wall Street Journal said SpaceX privately showed investors a prototype AI device before its June IPO. The description was unusually specific. A handset slimmer than an iPhone. A proprietary operating system. Chips from Qualcomm. And Grok, the AI from xAI, woven all the way through.

              According to the Journal, the device connects to an idea Musk has chased for years. The everything app. One device, one platform, where you message, pay, watch, and talk to an AI assistant. Starlink provides the connection. Grok provides the intelligence. The handset would be the doorway to all of it.

              The timing matters too. The whole industry is racing to build the gadget that replaces the smartphone in the age of AI. OpenAI has hired away some of Apple’s most famous hardware minds to build a device of its own. If a Musk handset is real, it isn’t a side project. It’s an entry into the biggest hardware fight of the decade.

              Musk has a complicated history with phones. In January, he said a Starlink phone was not out of the question at some point. In February, after a Reuters report, he stated flatly, we are not developing a phone. And this week, he dismissed the Journal’s story with just those two words. Utterly false.

              There’s an older breadcrumb as well. The Journal reported last year that Musk once considered building a smartphone out of pure frustration with Apple, because Apple controls how apps like X reach their users. Musk joked that the idea of making a phone made him want to die. And yet it keeps resurfacing, in report after report.

              Notice what those two words don’t do. They don’t say which part of the report was wrong. They don’t say no prototype exists. They don’t say no investor ever saw a device. It was a denial with no edges. And markets hate a denial they can’t measure.

              That brings us to the reaction. SpaceX stock fell about seven percent on Wednesday. That extended a slide that’s been running since the stock peaked in June. And it briefly dropped Musk’s personal fortune back under a trillion dollars. Ending, at least for the moment, his run as the world’s first trillionaire.

              For a company barely three weeks into public life, this was a lesson in what it signed up for. Private investors read pitch decks and wait years. Public markets read headlines and reprice you by dinner time. SpaceX spent its entire life as a private company. Most recently, the most valuable one on Earth. It’s learning what the other side feels like.

              To be fair, the idea itself isn’t far fetched. If any company could build this, it’s probably this one. SpaceX and Tesla have real manufacturing muscle. They have access to chips. Starlink already beams phone signals from space through a deal with T-Mobile. And SpaceX president Gwynne Shotwell recently told investors the company is exploring a full mobile phone service here on the ground.

              If you’ve been with us a while, this rhymes with episode twenty-three, where we covered SpaceX’s ambition to become a wireless carrier in its own right. The pieces for a Musk phone genuinely exist. Connectivity. Chips. An AI assistant. A payments push through X. The hardware would just be the final piece snapping into place.

              But look at the deeper pattern, because this is the real story. A product that officially doesn’t exist, described in a report the CEO denies, moved one of the most valuable companies on Earth by tens of billions of dollars. In one afternoon. No earnings. No launch. No recall. Just a story, and a denial.

              One analyst note put it bluntly. Musk companies get a massive benefit of the doubt on product promises. Their valuations rest partly on products that are more ideas than reality. That’s the Musk premium we covered back in episode twenty-nine. Investors pay today for the products Musk might ship years from now.

              Compare that with how mature companies trade. When a rumor about an unannounced Apple product gets denied, Apple stock barely blinks, because Apple is valued on the billions of devices it already sells. SpaceX moved this hard because so much of its price lives in the future tense.

              That premium is usually described as a gift. This week showed the other side of it. When a big chunk of your market value rests on belief in future products, belief can move the price all by itself. Up when the story is exciting. Down when the story gets confusing. The phone didn’t have to be real to cost fifty billion dollars. The story did that on its own.

              So set the phone aside and look at what the market just did. It priced a rumor, then priced a denial, and neither price had anything to do with rockets, satellites, or cars. The signal this week isn’t whether the device exists. It’s that SpaceX now trades on narrative momentum. And narrative can be denied, but it can’t be recalled.

              Watch two things from this point. Whether more details of the device leak out, because reports this specific rarely arrive alone. And whether SpaceX’s push into phone service keeps growing, because a carrier without a handset never stays that way for long.

              That’s the signal. I’m Lena Ruiz with the Tesorb Signal podcast. For more news about Tesla, SpaceX, and Elon Musk’s companies, visit our website at tesorb.com.

                At the end of last year, Elon Musk made a promise about his brain-implant company. In 2026, he said, Neuralink would begin high-volume production of its devices, and move to a surgery so streamlined that a robot could do almost all of it. High volume. Now we’re halfway through that year. Count the people who actually have one of these chips in their head. The number is twenty-six.


                This is Tesorb Signal, and I’m Lena Ruiz. Neuralink is the corner of Musk’s empire that sounds the most like science fiction. A chip in your skull that lets you move a computer cursor, or type, using nothing but thought. And unlike a lot of Musk promises, this one is already real. People are using it, today.

                So the question isn’t whether it works. It’s how fast it can grow. Today, three things. Where Neuralink actually stands right now. Why the pace is so much slower than the promises. And what’s really holding it back, which is not the thing most people would guess.

                Start with what’s true, because it’s genuinely remarkable. As of the middle of this year, Neuralink has placed its implant in twenty-six people. The first was a young man named Noland Arbaugh, paralyzed from the shoulders down after a diving accident.

                In early 2024, he became the first human to control a computer with a Neuralink chip. He’s played video games and online chess, browsed the web, posted online, all by thinking. For someone who couldn’t move his hands, that’s not a demo. That’s a life partly handed back.

                We first met Neuralink back in episode twenty, when we looked at its work decoding speech for people who’ve lost the ability to talk. That effort is still running, alongside the main study for people with paralysis. The company has also pushed beyond the United States, opening trials in Britain, Canada, and the United Arab Emirates.

                The device itself is about the size of a small coin. It sits flush in the skull, replacing a little piece of bone, and it listens to the brain through more than three thousand hair-thin electrodes. For the people in these trials, many of whom haven’t used their hands in years, it isn’t a gadget. It’s a door back to the world.

                And the ambition runs past movement. Neuralink is also developing a project it calls Blindsight, aimed at restoring a basic form of vision to people who’ve lost their sight, by feeding signals straight to the brain.

                United States regulators have already tagged it a breakthrough device. If it works, the same kind of chip that hands back motion could one day hand back sight. That’s the promise that makes this company so easy to root for.

                So that’s the headline, and it’s a good one. Now the data underneath it. Twenty-six people, over roughly two and a half years of human trials. That is real, and it is steady. It is also a very long way from the phrase high-volume production.

                And to be fair to Neuralink, this is exactly how serious medicine is supposed to move. You don’t mass-produce brain surgery. Each patient is studied closely. Each implant is watched for months for any sign of trouble.

                And there has been trouble to watch. With that very first patient, some of the ultra-thin threads pulled back from the brain in the weeks after surgery, and the implant started losing its signal. Neuralink adapted the software and recovered most of the function. But it was a reminder that this is the frontier, and the frontier is unforgiving.

                So a careful pace isn’t a failure here. It’s the responsible choice. The gap worth flagging is only between that careful reality and the language of a factory floor.

                Which brings us to the real question. What is actually slowing this down? For years, the honest answer was regulators. Getting permission to put a device inside a living human brain is, rightly, one of the hardest approvals in all of medicine.

                But Neuralink has now cleared that bar, repeatedly, in several different countries. Approval is no longer the wall. The new wall is surgery itself.

                Right now, implanting one of these takes a specialized robot and a skilled surgical team, working on a single patient at a time. You cannot scale that the way you scale a phone factory. This is why Musk keeps talking about automating the operation, making it faster and far less dependent on rare expertise.

                That automated surgery is the bet that turns twenty-six into thousands. And it is, by a wide margin, the hardest part left. So when Musk says high-volume production, the chips are arguably the easy bit. Building enough devices was never really the constraint. Performing enough safe surgeries to use them is.

                Step back and the gap gets vivid. Millions of people live with paralysis, or with ALS, who might one day want this. Twenty-six have it. That isn’t a knock on Neuralink. It’s the size of the mountain still in front of it.

                One gap tells the whole story. The promise is a factory. The reality is twenty-six people, each one a small miracle, each one implanted the slow, careful way. The technology has crossed the line from science fiction into medicine. What it hasn’t done yet is cross from medicine into scale.

                And the distance between those two is measured in operating rooms, not headlines. If Neuralink solves the surgery, that number stops being twenty-six and starts doubling. If it doesn’t, this stays a profound gift for a lucky few. Watch the patient count. It’s the only number that matters.

                That’s the signal. I’m Lena Ruiz with the Tesorb Signal podcast. For more news about Tesla, SpaceX, and Elon Musk’s companies, visit our website at tesorb.com.

                  In 2011, a television interviewer asked Elon Musk about a Chinese car company called BYD. Musk laughed. On camera. He said he didn’t think they made a great product. Fast forward to today. That same company just sold more electric cars in a year than Tesla. By about six hundred thousand of them. Nobody at BYD is laughing now.


                  This is Tesorb Signal, and I’m Lena Ruiz. For its entire life, Tesla has been the world’s best-selling maker of fully electric cars. That’s been the identity. The pioneer. The default choice.

                  In 2025, it lost that title. And it lost it to the very company its own founder once waved away. Today, three things. How the crown actually changed hands. How BYD pulled it off. And why Tesla, strangely, doesn’t seem all that bothered.

                  Start with the numbers, because they’re stark. In 2025, BYD sold around two and a quarter million fully electric vehicles. Tesla delivered about one and a half million. That was the first full year BYD has ever finished ahead.

                  And the two are moving in opposite directions. BYD’s electric sales grew nearly thirty percent. Tesla’s deliveries fell, its second annual drop in a row. This wasn’t a photo finish at the line. It was a handoff.

                  And that only counts pure electric cars. Add in BYD’s plug-in hybrids, which Tesla doesn’t build at all, and the company moved well over four million vehicles last year. This isn’t a niche challenger. It’s quietly become one of the largest carmakers on Earth.

                  It helps to know where those sales come from. Most of them are inside China, now the biggest and most electric car market on the planet. BYD owns its home turf the way Tesla once owned early adopters everywhere. Win the largest market decisively, and the global totals follow.

                  It’s worth pausing on how fast this happened. A decade ago, BYD was barely known outside China. Tesla was the name that defined the electric car. To go from a punchline in a 2011 interview to the global sales leader is one of the quickest role reversals the car industry has ever seen.

                  So how did BYD do it? Three ways, mostly. The first is price. Its cars are simply cheaper. It sells models that undercut anything in Tesla’s lineup, including small EVs priced for buyers Tesla doesn’t even try to reach.

                  And that price edge isn’t a subsidy trick. BYD didn’t start as a carmaker. It began in the nineteen-nineties making rechargeable batteries for phones. So when the world pivoted to electric cars, it already owned the single most expensive part of one.

                  It builds its own batteries, its own chips, even its own ships to carry the cars overseas. When you control that much of your own supply chain, you can charge less and still turn a profit. Cheap, here, is an engineering choice, not a fire sale.

                  The second is range, as in product range. BYD builds an enormous lineup, from bargain city cars to luxury sedans, while Tesla sells a small handful of models. More shelves, more shoppers.

                  And BYD keeps refilling those shelves. New models arrive constantly. Tesla’s core cars, by contrast, have been on sale for years with only the occasional update. One company floods the showroom with choice. The other bets that a few products, done well, are enough.

                  The third is timing. 2025 was a rough year for Tesla. The United States ended its seventy-five-hundred-dollar tax break for EV buyers, and demand cooled. In Europe, Tesla’s sales fell sharply, while BYD’s surged.

                  Europe stings most. It was supposed to be Tesla’s stronghold, the market that loved electric cars first. Watching a Chinese newcomer outsell you on that turf, in a single year, is the kind of reversal that tells you the contest has changed shape.

                  One caveat worth saying out loud. BYD barely sells passenger cars in the United States, thanks to steep tariffs. So this is a global crown, not an American one. In your local Tesla showroom, you may not feel any of this. Worldwide, the ground has shifted.

                  Now, the part that makes this strange. Tesla, by all appearances, is not fighting very hard to win this title back. And there’s a real logic to that.

                  We talked back in episode thirty-two about Tesla’s central bet. That the future isn’t selling cars at all. It’s robotaxis and self-driving software. Musk has all but told investors to stop valuing Tesla as a carmaker.

                  From that seat, losing the volume crown to BYD matters less than winning the autonomy race. And to be fair to Tesla, it still earns far more profit on each car it sells than BYD does. It traded market share for fatter margins and a moonshot. That cushion is real.

                  But it’s a genuine gamble. The car business is the thing paying the bills today. Hand your lead in that business to a hungry rival, while chasing a self-driving future that hasn’t fully arrived, and you had better be right about the future. Cushions get thinner.

                  The crown changed hands while everyone was looking up. At rockets. At robots. At a self-driving tomorrow. BYD didn’t beat Tesla with a better story. It beat Tesla with cheaper cars, far more of them, sold all over the world.

                  Tesla decided that particular race wasn’t worth winning. Maybe that’s visionary. Maybe it’s a company talking about tomorrow because today got harder. Either way, the title it was built on now belongs to someone else.

                    This month, Elon Musk added about a hundred and sixteen billion dollars to his net worth in a single move. He didn’t sell a thing. He didn’t launch a rocket or ship a single car. He just exercised a stack of stock options he’d been fighting over in court for years. But the money is the part everyone’s talking about. The part that matters more is the votes that came with it.


                    This is Tesorb Signal, and I’m Lena Ruiz. A few weeks ago, in episode forty, we covered Musk becoming the world’s first trillionaire. This is the other half of that story.

                    And it’s less about his bank account than about his grip on Tesla. Today, three things. What Musk actually did this month. Why one specific number, twenty-five percent, has quietly driven his decisions for years. And what tightening his control means for the millions of other people who own a slice of Tesla.

                    So what happened. Back in 2018, Tesla’s board handed Musk a pay package with no salary at all. Just options. The right to buy a mountain of Tesla stock, but only if he hit a set of wildly ambitious targets. Almost nobody thought he’d reach them. He reached them.

                    Then the whole thing landed in court. A Delaware judge threw the package out, ruling the process that approved it was unfair to shareholders. Late last year, a higher court reversed that and put it back. And this month, Musk finally pulled the trigger.

                    It was, at the time, the largest pay package in corporate history. And it became a years-long symbol of a bigger question hanging over Tesla. Is Elon Musk an employee the board oversees, or the one truly in charge? This month, he started answering that question in votes.

                    He exercised roughly three hundred million options at the price set back in 2018, a tiny fraction of what the shares are worth today. No open-market sale was involved. The new shares are even locked up for years. But what he got immediately was the thing he was really after. The vote attached to every single one of them.

                    Worth being clear on the mechanics. Musk didn’t pocket a hundred and sixteen billion dollars in cash. To cover the cost and the taxes, Tesla simply held back a slice of the shares. He walked away with more stock and more votes, not a giant cash payout. On paper, his wealth jumped. In his actual bank account, far less changed.

                    So why do this now, years before he had to? One word. Power. Before this move, Musk controlled around thirteen percent of Tesla’s shareholder votes. Afterward, he’s near twenty. And the number he has said he wants is twenty-five percent.

                    That figure isn’t random. Back in early 2024, with his stake down around thirteen percent, Musk said publicly that he wasn’t comfortable steering Tesla deeper into artificial intelligence and robots, the company’s entire future, with so little control.

                    He wanted enough voting power to be, in his words, influential, but not so much that he couldn’t be overturned. Twenty-five percent was the line he drew. This month’s move was a long stride toward it. He can’t sell these shares for years, but he holds the votes today.

                    And to see why that matters, picture how a company like Tesla makes its biggest decisions. Mergers. Huge product bets. Who sits on the board. All of it comes down to shareholder votes. The more votes one person controls, the harder it becomes for everyone else to say no.

                    And the timing points at something specific. SpaceX just went public and is now worth more than two trillion dollars. That’s set off open speculation about Musk one day folding Tesla and SpaceX together. A merger on that scale would need shareholder approval. The more votes Musk holds, the easier such a deal is to push through, and the harder it is for anyone to block.

                    Now, the fair case for Musk is genuinely strong, and worth saying out loud. He pulled Tesla back from the edge of death more than once. Anyone who bet on him fifteen years ago and held on has been rewarded many times over.

                    And twenty-five percent is not a king’s share. It still leaves three-quarters of the votes in everyone else’s hands. Musk himself framed it as wanting influence, not a blank check.

                    It’s also worth noting that Tesla’s shareholders recently voted to reinstate this pay deal themselves. It wasn’t forced on them. A majority backed handing Musk both the payday and the influence that came with it.

                    But control cuts both ways. The same concentrated votes that let a visionary move fast also make it harder to rein him in when shareholders disagree. We saw a version of this tension back in episode twenty-one, when we followed the money quietly flowing between Musk’s different companies.

                    The tighter his grip, the more Tesla’s direction rides on one person’s judgment. About AI. About robotaxis. About whether to fold his empire together one day. For believers, that’s the entire point. For skeptics, that’s the entire risk.

                    The money was always the distraction. The headline this month was another eye-watering number sitting next to Elon Musk’s name. The real story was much quieter, and far more lasting.

                    He used a court win and a years-old pay deal to move closer to locking down control of Tesla, right as the company stakes everything on artificial intelligence. The money makes the headlines. The votes make the decisions.

                    That’s the signal. I’m Lena Ruiz with the Tesorb Signal podcast. For more news about Tesla, SpaceX, and Elon Musk’s companies, visit our website at tesorb.com.

                      Tesla likes to say its cars drive themselves ten times more safely than you do. It’s a stunning claim. If it’s true, it rewrites everything about how we move. Last week, that claim ran into a house. A Tesla in a Houston suburb veered off a residential street and into a home. The seventy-six-year-old woman inside was killed. The driver told police the car was driving itself.


                      This is Tesorb Signal, and I’m Lena Ruiz. Federal safety regulators have opened an investigation into that crash. And it lands at the exact moment Tesla’s whole self-driving story is being pulled apart.

                      Not over whether the technology works. Over a single word. Safe. And what number you’re allowed to compare it to. Today, three things. The claim, and the crash that put it under a microscope. How that ten-times-safer math is actually built. And what regulators, and Tesla’s own former staff, now say about it.

                      Tesla’s pitch is simple and powerful. Cars running its Full Self-Driving software, branded FSD, crash far less often than human drivers do. That’s the company’s claim. Its finance chief has put it at ten times safer. The board chair repeated it. Musk has shown charts claiming eighty-five percent fewer crashes.

                      For a company whose entire future now rests on robotaxis, that number isn’t marketing. It’s the foundation. The whole multi-trillion-dollar story depends on people believing the car is safer than they are.

                      So when a car using that system drives into a home and a person dies, regulators don’t just file it away. The federal auto-safety agency opened a special investigation within a day. Musk, for his part, posted that the crash made no sense to him.

                      This isn’t the first time. Over the past decade, federal regulators have opened dozens of separate investigations into crashes involving Tesla’s driver-assist systems. The Houston crash is the latest data point, not a lone one.

                      So how do you actually get to ten times safer? A Reuters investigation published last month dug into the method. And the finding was blunt. The comparison isn’t apples to apples.

                      Tesla counts crashes in its own newer cars, the kind serious enough to set off an airbag. Then it stacks that against federal data for a much broader category. Every crash anywhere in the country bad enough to tow a car away, across the entire aging national fleet.

                      Think about what that does. You’re lining up a brand-new car’s worst wrecks against every fender-bender in America, in vehicles of every age and condition. Naturally, the new car looks safer. Reuters reported the method inflates Tesla’s safety edge by roughly three times.

                      Strip the marketing out, and the real-world picture gets murkier. Take Tesla’s own robotaxi fleet in Austin. By independent analysis of the reported data, those cars logged about one crash every fifty-seven thousand miles.

                      Researchers cited by Bloomberg and Electrek put that at roughly four times the crash rate of a human driver in similar city conditions. For comparison, Waymo, the Google-spun rival, has driven vastly more miles with a far lower rate. That’s the contrast the headline number quietly hides.

                      Now, to be fair to Tesla, the software is improving, and improving fast. Plenty of owners describe drives where the car handles tricky streets better than they would have. That progress is genuine, and it matters.

                      But two things are happening at the same time. The federal safety agency now has several open investigations into the system. One of them covers more than three million Teslas. And it has reached the final stage before regulators can force a recall.

                      The specific worry is almost poetic, given this week’s crash. Tesla relies on cameras alone. No radar, no laser sensors. Regulators are asking whether the system can reliably tell when those cameras are blinded by sun glare, fog, or dust, and warn the driver in time.

                      It’s a deliberate design choice. Rivals like Waymo bolt on overlapping sensors, lasers and radar, so if one goes dark, the others still see. Tesla bet that cameras and a powerful enough computer could do the whole job, cheaper. Elegant if it works. Unforgiving if a camera is blinded at the wrong moment.

                      And it isn’t only regulators raising a hand. In that same Reuters report, seven of nine former Tesla data labelers, the people paid to review the car’s own footage, said they would not trust the system to drive them. This month, two United States senators demanded the agency independently check Tesla’s safety math.

                      The courts aren’t waiting, either. Civil juries have already begun siding with crash victims’ families, handing down large verdicts against Tesla in cases tied to its driver-assist systems. Each one chips away at the safer-than-human story.

                      There’s a quieter danger buried in all this, too. The better FSD gets, the more drivers relax and stop watching the road. So a system that’s genuinely improving can become more dangerous at the very moment people start trusting it completely.

                      So the word to question isn’t self-driving. It’s safer. Tesla may well be building a system that one day saves lives at a scale we can’t ignore. That future is worth rooting for.

                      But right now, the ten-times-safer claim rests on a comparison that critics, and some of the company’s own former employees, say is stacked in Tesla’s favor. A safety number is only as honest as the thing you measure it against.

                      Until that comparison is apples to apples, the headline is a promise, not a proof. And a seventy-six-year-old woman in Texas is a reminder of what’s riding on the difference.

                    • SpaceX Won the IPO. Then It Went Back for More.

                      Two weeks after the biggest IPO in history, SpaceX borrowed $25 billion more. The money is easy. The question is where it all goes, and who’s funding the bet now that the doors are open.

                        Two weeks ago, SpaceX pulled off the biggest stock sale in history. Seventy-five billion dollars, in a single afternoon. Elon Musk became the world’s first trillionaire before lunch. And then, just this week, the company did something that should make you look twice. It went out and borrowed twenty-five billion dollars more.


                        This is Tesorb Signal, and I’m Lena Ruiz. The story almost everyone told about the SpaceX IPO was a victory lap. The richest company debut ever. A founder crossing a line no human had crossed before.

                        But the story sitting in the fine print is quieter, and a lot more revealing. It’s about cash. How much this company burns, how fast, and who’s paying for it now that the doors are open to the public.

                        Today, three things. What that twenty-five billion dollar loan actually is. Where all the money goes. And why going public this month raised the stakes for SpaceX instead of settling them.

                        So start with the loan. This week, SpaceX went to the bond market, the place big companies go to borrow, looking for twenty billion dollars. Demand was so heavy that it walked away with twenty-five billion instead. By some accounts, investors offered nearly four times what it set out to raise.

                        Let that sink in. Five of the largest banks on Wall Street lined up to run the sale. This is not a company scraping the couch cushions for change. It’s the opposite. Lenders are competing to hand it money.

                        And there’s a reason SpaceX reached for a loan instead of just selling more stock. Selling shares splits the company into more and more slices, watering down everyone who already owns it, Musk included. Borrowing sidesteps that. The catch is that debt comes with a bill that shows up on a calendar, rain or shine.

                        And this loan arrives just months after SpaceX took out a separate, multi-billion-dollar bridge loan back in the spring. So the obvious question is the one worth asking. If money is this easy to raise, why does a company worth more than two trillion dollars need so much of it?

                        The answer is that SpaceX spends at a scale that’s honestly hard to picture. Last year, the company lost close to five billion dollars. Now, that loss isn’t a sign the business is broken. Far from it.

                        Starlink, the satellite internet service beaming down from thousands of small spacecraft, is a genuine, growing, profitable business. We dug into that back in episode thirteen. Starlink is the engine quietly paying the bills.

                        The losses come from everything SpaceX is trying to build next. Picture a family that earns a great salary, but is mid-renovation on three enormous houses at the same time. The income is real. It’s just dwarfed by the construction.

                        Two projects eat most of the cash. The first is Starship, the giant, fully reusable rocket meant to haul cargo, then astronauts, and one day settlers. Reusability is the whole bet. Catch the rocket, refuel it, fly it again, and the cost of reaching space falls through the floor.

                        But getting there means building, launching, and sometimes blowing up very expensive hardware, over and over. The second project is artificial intelligence. Earlier this year, SpaceX absorbed xAI, the company behind the Grok chatbot.

                        And modern AI is brutally, almost comically expensive. It runs on warehouses full of chips that cost billions to buy and a fortune to power. In just the first three months of this year, the bulk of SpaceX’s spending poured into that side of the house.

                        Now layer in the part that changed this month. SpaceX is public. For more than twenty years, Musk fought to keep it private, precisely so he’d never have to explain himself to outside shareholders every ninety days. That shield is now gone.

                        And the market wasted no time. The stock priced at one hundred thirty-five dollars a share, jumped on its first day, and then, within days, began sliding back down. One research firm slapped a sell rating on it almost immediately, arguing the price had run too far ahead of what the business does today.

                        And the crowd that’s exposed now is different. A large slice of the IPO went to ordinary investors buying through their brokerage apps, not just big Wall Street funds. So when this stock swings, it isn’t only institutions feeling it. It’s regular people who clicked buy.

                        To be fair, the bulls have a serious case, and it’s worth stating plainly. SpaceX has at least a ten-year head start on everyone else in getting to orbit cheaply. One analyst told CNBC you can’t judge a company like this by a single quarter. You have to look out twenty years.

                        That may well be right. But that’s the whole tension in one sentence. SpaceX is built for the twenty-forties. Its stock now trades by the afternoon. And the debt makes that tension sharper.

                        Equity is patient money. Shareholders can sit and dream about Mars. Borrowed money is not patient. A loan has to be paid back on schedule, whether or not the next Starship sticks its landing.

                        The headline was the price tag. The story is the bill. The IPO made Elon Musk the wealthiest person alive and handed SpaceX an enormous war chest. But it didn’t make Starship one dollar cheaper, or AI one watt less hungry. The spending that drove those losses is still there. If anything, it’s accelerating.

                        What actually changed is who’s funding the bet. It used to be a small circle of private insiders who knew exactly what they signed up for. Now it’s the public, the bond market, and anyone who bought a few shares on their phone.

                        The IPO wasn’t the finish line. It was the starting gun on the most expensive stretch yet.
