Elon Musk has lost his lawsuit against Sam Altman and OpenAI, with the jury finding that his claims were filed too late due to the statute of limitations. Musk had accused Altman and OpenAI of 'stealing a charity' by creating a for-profit affiliate of the frontier AI lab. The trial focused on whether and when Altman and the other defendants had made and broken promises to Musk, but his case failed to convince jurors that he had a valid claim. The verdict means that one major threat to OpenAI, a possible restructuring, is now off the table ahead of its reported IPO.
