Musk’s first week on the stand sharpened the stakes but complicated his betrayal narrative, as testimony turned to Microsoft’s capped investment, OpenAI’s restructuring, xAI’s use of OpenAI models, and what his $38 million donation was meant to buy.

Musk’s Trial Against OpenAI Hits Some Rough Spots in First Week

Elon Musk set out to tell a jury that his falling out with OpenAI was a simple tale of betrayal.

But the many questions that came up during the billionaire’s three days on the witness stand this week revealed the decade-long saga to be complicated — with twists and turns that cast some doubt on Musk’s version of events.

Musk has…

• “It would be weird if Musk win this. They have proof that he tried to make OpenAI a part of his other companies.” — r/OpenAI (165 upvotes)

  Our take: We think that is the pressure point for Musk: evidence that he explored folding OpenAI into his own corporate orbit makes the betrayal story less clean. But it is not an automatic legal knockout; the jury still has to connect the record to donor intent, charitable purpose, and the specific claims in the case.

• “Just make your models open source and his lawsuit loses all basis... hes right you are open ai you should have remained that way.” — r/OpenAI (29 upvotes)

  Our take: We get the emotional force of this: if your name is OpenAI, people will keep asking where the open part went. Legally, though, releasing models now would not necessarily cure an alleged misuse of donations years ago, and commercially it would collide with the Microsoft deal, safety arguments, and OpenAI’s current business model.

• “Whoever loses will just appeal. Nothing will change for years.” — r/OpenAI (13 upvotes)

  Our take: The cynicism is earned; a case this big almost begs for appeals. Still, the trial can matter before the last appeal is over, because factual findings, injunction risk, and governance pressure can move markets and boardrooms long before the final mandate comes down.
