In this episode of Galaxy Brain, Charlie Warzel explores the burgeoning industry of prediction markets. These platforms let people wager on everything from elections and award shows to the most trivial internet ephemera, framing bets as tradable “shares” that rise and fall like stocks. With billions in weekly trading volume, massive new funding rounds, and even a CNN partnership with the prediction-betting platform, Kalshi, prediction markets are quickly moving from a niche curiosity to a mainstream-media fixture—openly touting ambitions to financialize everything.

Warzel is joined by writer Max Read, who argues that prediction markets sit at the intersection of gambling, finance, and a broader “suckerification” economy aimed at young men. Together they unpack whether the markets actually reflect the “wisdom of crowds” or whether they’re little more than a meta-game of vibes, ideology, and misvalued dumb money. The pair explore the culture of these platforms and offer a diagnosis of the attention economy: When it’s hard to sell anything directly, it’s easier to sell derivatives of everything. Prediction markets may promise clarity, Warzel and Read suggest, but what they really offer is another way to feel excitement in a world that feels rigged.

In this episode of Galaxy Brain, Charlie Warzel turns the camera on himself to ask a simple question: Why are you seeing his face? 

Using YouTube’s takeover of podcasts as a starting point, he explores how video has devoured audio and turned podcasts into something closer to daytime TV and late-night talk shows. NPR’s Rachel Martin, host of the celebrity-interview show Wild Card, joins to talk about her own shift from intimate, audio-only conversations to highly visible video chats with mega-celebrities. She explains how the visual layer changes everything—from building trust with guests and audiences to deepening parasocial relationships, and why showing your face is necessary in a low-trust media world.

To trace the business and cultural arc of this pivot, Bloomberg reporter Ashley Carman explains the rise and fall of the podcast “gold rush”—from the Serial era to Spotify’s billion-dollar bet, to the collapse of expensive narrative audio and YouTube’s emergence as a true power player. Then, writer and Plain English host Derek Thompson joins to explain his theory that “everything is television now.” Warzel and Thompson explore how short-form video, autoplay feeds, and video podcasts are reshaping our attention, our politics, and even our sense of self—turning podcasts into background “wallpaper” while nudging more of us into broadcasting our lives. Together, the conversations sketch a weird, slightly berserk future where video podcasts aren’t just a format—they’re a window into a lonelier, more fragmented, video-first culture.

In this episode of Galaxy Brain, Charlie Warzel explores the strange, unsettling relationships some people are having with AI chatbots, as well as what happens when those relationships go off the rails. His guest is Kashmir Hill, a technology reporter at The New York Times who has spent the past year documenting what is informally called “AI psychosis.” These are long, intense conversations with systems such as ChatGPT that can spiral or trigger delusional beliefs, paranoia, and even self-harm. Hill walks through cases that range from the bizarre (one man’s supposed math breakthrough, a chatbot encouraging users to email her) to the tragic, including the story of 16-year-old Adam Raine, whose final messages were with ChatGPT before he died by suicide.

How big is this problem? Is this actual psychosis or something different, like addiction? Hill reports on how OpenAI tuned ChatGPT to be more engaging—and more sycophantic—in the race for daily active users. In this conversation, Warzel and Hill wrestle with the uncomfortable parallels to the social-media era, the limits of “safety fixes,” and whether chatbots should ever be allowed to act like therapists. Hill also talks about how she uses AI in her own life, why she doesn’t want an AI best friend, and what it might mean for all of us to carry a personalized yes-man in our pocket.

In this episode of “Galaxy Brain,” Charlie Warzel sits down with Eliot Higgins, founder of the open-source investigative collective Bellingcat, to examine how our public sphere slid from healthy debate into what Higgins calls “disordered discourse.” Higgins is an early-internet native who taught himself geolocation during the Arab Spring and later built Bellingcat’s global community. He has spent the past decade exposing war crimes and online manipulation with publicly available data. Higgins has recently come up with a framework to help understand our information crisis: Democracies function only when we can verify truth, deliberate over what matters, and hold power to account. All three are faltering, he argues.

In this conversation, Warzel and Higgins trace the incentives that broke the feed: how algorithms reward outrage, how “bespoke realities” form, why counterpublics can devolve into virtual cults, and what “simulated” accountability looks like in practice. They revisit Higgins’s path from early web forums to Bellingcat, look at the MAGA coalition as a patchwork of disordered counterpublics, and debate whether America is trapped in a simulated democracy. Higgins offers a clear diagnosis—and a plan for how we might begin to claw back a shared reality.

In this inaugural episode of Galaxy Brain, Charlie Warzel examines the state of the internet as it stands now in November 2025 with Hank Green, a true citizen of the internet—somebody who has made a living riding the algorithmic waves of the social web. Warzel and Green look back on a time when the internet felt small, more serendipitous, and inspiring, and try to tease apart what went wrong. Are people starting to leave TikTok? How exactly did the internet turn into a misery machine? What makes a great headline? Why is it easier now for some people to trust creators over institutions? Green helps make sense of the internet we live on and offers his reasons for why it might get worse before it gets better (but it could get better!).

The internet has warped public life: Politicians behave like influencers, the economy resembles a casino, and people can no longer agree upon a consensus reality. New conspiracy theories, memes, and main characters seem to pop up every day. A constant war is on for your attention, and it’s easy to feel lost. Each week, Galaxy Brain and its host, Charlie Warzel, invite you into conversations to make sense of the fire hose of information. Is AI destroying our ability to think? Do your grandparents have a screen-time problem? Galaxy Brain looks beyond the algorithm and anchors you to the real—however strange it may be.

Holy Week: The story of a revolution undone.

The assassination of Dr. Martin Luther King Jr. on April 4, 1968, is often recounted as a conclusion to a powerful era of civil rights in America, but how did this hero’s murder come to be the stitching used to tie together a narrative of victory? The week that followed his killing was one of the most fiery, disruptive, and revolutionary, and is nearly forgotten. Over the course of eight episodes, Holy Week brings forward the stories of the activists who turned heartbreak into action, families scorched by chaos, and politicians who worked to contain the grief. Seven days diverted the course of a social revolution and set the stage for modern clashes over voting rights, redlining, critical race theory, and the role of racial unrest in today’s post–George Floyd reckoning.
