US Jury Rejects Musk's Lawsuit Against OpenAI

However, the jury never decided whether these accusations were true. Instead, it ruled that Musk had waited too long to file the case under California's statute of limitations — the legal deadline for bringing certain claims. Musk's lawyers had called former OpenAI executives, including Mira Murati and Ilya Sutskever, to argue that Altman was deceptive. OpenAI's lawyers responded with evidence that Musk himself had once supported the for-profit change and had even sought "total control" of the company before leaving in 2018.

Musk vowed to appeal on his platform X, calling the verdict "a calendar technicality" and accusing the judge of bias. OpenAI's lawyer William Savitt said the jurors had "reached the right result quickly". Microsoft, which has invested around $13 billion in OpenAI and was also named in the suit, said it remained committed to the partnership. The ruling lifts a major cloud over OpenAI as it prepares for a possible public share offering worth around $1 trillion later this year. Meanwhile, Musk plans a separate stock listing for SpaceX after merging it with his rival firm xAI.
