The Verdict
On May 18, 2026, a nine-member jury in U.S. District Court in Oakland returned a verdict in Musk v. OpenAI after roughly 90 minutes of deliberation.
All claims dismissed. Every single one.
A three-week trial, filed in February 2024, two-plus years of litigation, and the question of whether Sam Altman and Greg Brockman “stole a charity” was dispatched in less time than a long lunch.
Judge Yvonne Gonzalez Rogers, who was hearing the jury’s findings as an advisory verdict before adopting them as her own, confirmed: “The court now confirms the prior indication that it would accept the jury’s findings as its own.”
What the Ruling Actually Said
Here is the important part: the jury did not decide whether Altman and Brockman breached their duties to OpenAI’s nonprofit mission.
The ruling was decided on statute of limitations. The jury found that Musk waited too long to bring his claims. Under California’s three-year limitations period for the underlying causes of action, the court found the claims time-barred.
This means the core allegation — that OpenAI’s conversion from a nonprofit-controlled entity to a for-profit partnership with Microsoft constituted a “breach of charitable trust” — was never adjudicated on the merits.
Claims dismissed included:
- Breach of charitable trust
- Unjust enrichment
- Claims against Microsoft for allegedly aiding and abetting the breach
The judge dismissed all three.
The Case in Brief
Musk co-founded OpenAI in 2015 alongside Sam Altman, Greg Brockman, and others. He donated approximately $38 million to it as a nonprofit. The founding premise, as Musk has described it, was that OpenAI would pursue artificial general intelligence for the benefit of humanity, not shareholders.
Between 2019 and 2023, OpenAI built a capped-profit structure that allowed Microsoft to invest $13 billion in the company in exchange for a 27% stake and access to the models. In October 2025, OpenAI completed its conversion to a Public Benefit Corporation.
Musk’s legal theory was that this transformation — from public-benefit nonprofit to billion-dollar commercial enterprise — constituted a betrayal of the founding mission. By accepting Microsoft’s money and building a commercial product empire, Altman and Brockman allegedly enriched themselves at the expense of the charitable trust Musk helped fund.
It is not an absurd argument on its face. But Musk filed it in 2024. The events he complained about began years earlier. The jury found he sat on the claims too long.
What Both Sides Said
OpenAI’s lead attorney William Savitt was direct:
“It’s not a technical decision, it’s a substantive one. You brought your claims too late, and you did it because you were sitting on them to use them as a weapon of a competitor who can’t compete in the marketplace.”
“What this lawsuit was was a hypocritical attempt to sabotage a competitor.”
Musk, posting on X:
“Calendar technicality.”
He announced plans to appeal to the Ninth Circuit Court of Appeals, arguing the court should have applied the continuing violation doctrine — a legal principle that can extend statute of limitations when a defendant’s wrongful conduct continues over time. Legal experts assess the appeal’s prospects as limited; courts give juries significant deference on factual questions like when claims accrued.
Musk’s attorney Marc Toberoff:
“This at its core is a travesty, and but for Musk, they get away with it and they shouldn’t.”
The Detail That Got Less Coverage
During the trial’s first week, Musk admitted under questioning that xAI distills OpenAI’s models.
Distillation — training one model using outputs from another — is a practice OpenAI’s terms of service prohibit for commercial competitors. The admission raised uncomfortable questions about whether Musk’s lawsuit against OpenAI was pursued while his own company was benefiting from OpenAI’s work.
OpenAI’s counterclaims against Musk and xAI Corp — alleging a “years-long harassment campaign” including talent poaching and deliberate business interference — were not dismissed before trial. Whether they proceed separately or were resolved as part of this verdict’s aftermath was not clearly addressed in immediate post-verdict coverage. Those claims may still be live.
Timing and the IPO Narrative
The verdict landed on May 18. OpenAI filed its confidential S-1 on May 22.
The four days between those events matter. Walking into an IPO roadshow with a billion-dollar lawsuit on the docket is a problem. Walking in with a complete dismissal is not. OpenAI’s litigation risk profile heading into the public markets is now substantially cleaner — the Musk case was the most prominent and the most ideologically threatening, given its direct attack on the company’s founding legitimacy.
That said: the case went out on a technicality, not a ruling on the merits. A future litigant making similar arguments about OpenAI’s charitable trust obligations — one who files on time — faces no precedent closing that door.
What Actually Happened, in Plain Language
Elon Musk believed OpenAI betrayed its mission. He may or may not have been right. A jury never got to decide. He filed too late, the court found, and that was that.
The founding question — whether you can promise to build AI for humanity, take billions from Microsoft, and convert to a for-profit corporation without legal consequence — remains unanswered in a courtroom. It has been answered in the market. OpenAI is worth approximately $852 billion.
The appeal will proceed. The Ninth Circuit will hear arguments, probably in 2027. The continuing violation theory Musk’s team plans to raise is a narrow legal argument that courts have applied inconsistently. Most observers expect the dismissal to stand.
What it means for xAI, for the IPO, and for the “stole a charity” argument as a cultural narrative: less than Musk hoped, more than OpenAI wanted to deal with during an IPO preparation.
