California Jury Dismisses Elon Musk Lawsuit Against OpenAI

A California jury unanimously dismissed Elon Musk’s lawsuit against OpenAI and CEO Sam Altman on Monday, ruling that the billionaire waited too long to challenge the company’s shift from a nonprofit to a for-profit entity [1]. The nine-member advisory jury reached its decision in less than two hours, concluding that Musk missed the three-year statute of limitations required to bring his claims [2]. Judge Yvonne Gonzalez Rogers of the U.S. District Court for the Northern District of California accepted the verdict, effectively ending a three-week trial that examined the origins of the ChatGPT maker [1].

Musk, who helped co-found OpenAI in 2015 and contributed $38 million in early funding, alleged that Altman and co-founder Greg Brockman breached a "charitable trust" by prioritizing profits and partnering with Microsoft [1]. He sought up to $150 billion in damages, the removal of Altman and Brockman from leadership, and the potential dismantling of the company’s for-profit arm [1]. Lawyers for OpenAI argued that Musk’s lawsuit was a "hypocritical attempt to sabotage a competitor" after he launched his own AI company, xAI, and that his early donations came with no strings attached [1].

The trial featured testimony from both Musk and Altman, highlighting a fractured relationship that soured as OpenAI grew into a massive commercial force [2]. While Musk claimed the company had abandoned its mission to benefit humanity, OpenAI’s legal team pointed to testimony from law professors who noted the for-profit structure has generated significant value for the nonprofit side [2]. Microsoft, which was also named as a defendant for its $13 billion in investments, welcomed the ruling as a resolution to the uncertainty surrounding the company’s business structure [1].

Because the court ruled on a calendar technicality, the jury never reached a verdict on the merits of Musk’s allegations regarding the company’s charitable mission [1]. Musk confirmed on social media that he intends to appeal the decision, maintaining his stance that the company’s leadership enriched themselves by "stealing a charity" [2].

The dismissal removes a major legal threat that could have forced a restructuring of OpenAI ahead of its expected public offering later this year [2]. Whether the appellate process can revive the core dispute over the company’s founding mission remains the central open question for the future of the organization.
