A three-week courtroom battle over the soul and structure of OpenAI has ended, for now, not with a ruling on ethics or AI governance but on timing: a jury concluded Elon Musk simply sued too late.

How the dispute began

Musk co-founded OpenAI in 2015 as a nonprofit meant to develop AI “for the benefit of humanity,” after donating roughly $38 million under what he said was a promise it would remain a charity.¹ As OpenAI created a capped for‑profit arm and deepened ties with Microsoft, Musk came to argue that Sam Altman and Greg Brockman had “stolen a charity” by enriching themselves and major investors.²

He sued in 2024, accusing them of breach of charitable trust and unjust enrichment, and sought up to $134 billion in disgorgement plus the removal of Altman and Brockman and an unwinding of OpenAI’s restructuring.³

Inside the trial

Across May 2026, the Musk v. Altman trial in Oakland aired years of internal power struggles and raised doubts about the trustworthiness of Altman and other AI leaders.⁴ Testimony showed jurors a nonprofit that had rapidly evolved into a hybrid AI powerhouse, and a founder—Musk—who had once pushed to fold OpenAI into Tesla and sought greater control.⁵

Yet the legal crux became narrow: whether Musk had missed the statutes of limitations. OpenAI argued he had ample reason to know about the 2019 for‑profit shift and early Microsoft investment well before 2021; Musk claimed his concerns crystallized only after later deals.⁶

The unanimous verdict

After about two hours of deliberations, the nine-person jury returned a unanimous advisory verdict: Musk’s claims were time‑barred.⁷ “The jury has delivered a unanimous verdict,” The Verge reported of the swift decision.⁸ Judge Yvonne Gonzalez Rogers immediately accepted the finding, dismissing the case on statute-of-limitations grounds without reaching the merits.⁹

That ruling cleared OpenAI, Altman, Brockman and Microsoft of liability and removed a major threat to OpenAI’s planned IPO and partnership with Microsoft.¹⁰

Musk’s response and his allies’ view

Musk quickly vowed to appeal, insisting “the judge & jury never actually ruled on the merits of the case, just on a calendar technicality,” and arguing there is “no question” Altman and Brockman “enrich[ed] themselves by stealing a charity.”¹¹ In a retweeted post, an account sympathetic to Musk blasted Gonzalez Rogers as an “activist judge” who had let Altman “hijack[] a nonprofit charity… and turn [it]” into a business.Elon Musk (elonmusk)¹²

His lawyer Marc Toberoff struck the same note in comments amplified by Musk on X, saying his “one-word reaction” was “Appeal” and declaring, “This war is not over,” while arguing you “can’t raise millions of dollars in a publicly subsidized charity and then just change the rules later.”Elon Musk (elonmusk)¹³

Musk also amplified a Wall Street Journal commentary claiming that while “a jury sided with Sam Altman and OpenAI in court,” Musk had “won in the court of public opinion.”Elon Musk (elonmusk)¹⁴

OpenAI, Microsoft and industry observers

OpenAI’s legal team framed the outcome as validation of their position that Musk’s lawsuit was “nothing more than an after-the-fact contrivance” and a “hypocritical attempt to sabotage a competitor.”¹⁵ A Microsoft spokesperson welcomed the decision, saying “the facts and the timeline in this case have long been clear” and reaffirming its commitment to working with OpenAI “to advance and scale AI for people and organizations around the world.”¹⁶

Analysts noted that the verdict lets OpenAI “shift its strategic focus to capitalizing on the AI revolution” and pursue a blockbuster IPO, intensifying its rivalry with Anthropic.¹⁷ But some experts argued the whole industry had lost: the trial underscored fears that AI’s foremost players are driven more by “money, power and personal rivalries” than by “love of humanity,” and left unresolved the deeper question of how far nonprofits may go in restructuring after courting donors and the public.¹⁸

MIT Technology Review and others pointed to the case as a lesson in how procedural rules like statutes of limitations can decide epochal tech disputes before judges ever weigh the underlying promises about AI and the public good.¹⁹
