Jury Throws Out Elon Musk's Lawsuit Against OpenAI in Under Two Hours

A federal jury in California needed less than two hours on May 18, 2026 to unanimously reject every claim in Elon Musk's lawsuit against OpenAI, Sam Altman, and Greg Brockman. The nine-person advisory panel found Musk had blown past the three-year statute of limitations, and U.S. District Judge Yvonne Gonzalez Rogers agreed, formally dismissing the case the same afternoon.

Musk had sued in 2024, alleging that Altman and Brockman broke a founding promise to keep OpenAI a non-profit and instead steered it into a for-profit structure now carrying an 52 billion post-money valuation after this spring's record 22 billion funding round. Jurors heard testimony from Musk in late April and concluded he should have filed his claim within three years of the 2019 corporate restructuring he was objecting to — not five years later, after the company had become a household name.

The ruling lifts a significant overhang from OpenAI just as it is courting public-market investors. Musk's discovery requests had threatened to drag executives into depositions over governance decisions stretching back to 2018, and a finding for the plaintiff could have forced structural concessions at exactly the moment the company is rehearsing for an IPO. With the case dismissed, that threat is — for now — off the table.

Musk responded on X within minutes, saying he plans to appeal. Legal observers were skeptical: the statute-of-limitations question is largely fact-driven and the judge's adoption of the advisory verdict gives the dismissal an unusually solid footing on review. Altman, in a brief post, thanked the jurors and added that OpenAI was ready to put the dispute behind it. Whether Musk's parallel xAI build-out, including last week's Grok Build coding CLI, becomes the next theater of this feud is now the more interesting question.
