Musk Loses OpenAI Lawsuit — Jury Unanimously Rejects $140 Billion Claim, Altman Secures Control

A nine-person jury in Oakland federal court ruled unanimously on May 18 to reject Elon Musk's lawsuit against OpenAI. Musk had sought $140 billion in damages and the removal of Sam Altman as CEO, but the jury found that Musk waited too long to file — dismissing all claims on statute of limitations grounds. Sam Altman won.

This was never just a corporate lawsuit. It was Silicon Valley's defining collision over who should control the world's most powerful AI company — and whether the nonprofit mission that launched it could legally bind its future. Had Musk won, OpenAI would have been forced back into nonprofit status and its IPO plans would have been dead. The outcome is the opposite.

What the Jury Found: Filed Too Late

The unanimous verdict turned on one thing: timing. The jury determined that Musk knew about the conduct he was suing over — OpenAI's for-profit conversion and Microsoft's investment — as far back as 2021. But he didn't file his lawsuit until February 2024. The statute of limitations had run out.

The jury never reached the merits of whether Altman and Brockman actually 'stole a charity.' The case was dismissed on procedural grounds. Microsoft, also named as a defendant, was cleared as well.

What Musk Was After

Musk donated $38 million in seed funding when OpenAI launched as a nonprofit in 2015. He argued the donation came with an implied condition: that AI would be developed for the benefit of humanity, not private profit. When Altman and Brockman created a for-profit subsidiary in 2019 and took billions from Microsoft, Musk said they violated that founding agreement. In 2025, OpenAI converted fully to a Public Benefit Corporation.

OpenAI was not a charity. It was never described as such during its formation.

Musk sought up to $150 billion in damages — to be paid to OpenAI's nonprofit foundation, not to himself — plus the removal of Altman and Brockman and a court order unwinding the for-profit conversion. All of it was dismissed.

What Altman Gains

The verdict frees Altman to consolidate his control over OpenAI without the legal overhang of Musk's claims. The IPO path, which had faced uncertainty depending on the trial outcome, is now significantly clearer. OpenAI is targeting a $1 trillion valuation for its public listing.

• Microsoft: invested tens of billions in OpenAI, legal risk from the suit now eliminated
• OpenAI IPO: $1 trillion valuation target, legal uncertainty over corporate structure resolved
• Altman: CEO and board control secured, Musk's removal claim gone

The ruling is not yet final. Because the jury's findings are advisory rather than binding, federal Judge Yvonne Gonzalez Rogers must adopt the verdict to make it official. Legal observers say the probability of the judge overturning a unanimous jury finding is low.

Why Musk Sued in the First Place

The official case was that OpenAI had abandoned its humanitarian mission for commercial gain. OpenAI's defense pointed to Musk's founding of xAI in 2023 and argued his real motive was competitive — using litigation to slow a rival. Altman said in court that 'jealousy' drove Musk's actions.

The rupture began when Musk left the board in 2018. He departed as OpenAI recognized it needed far more capital than a nonprofit could raise. After watching the company pivot toward Microsoft and away from his influence, Musk declared war through litigation six years later.

What Comes Next

Musk can appeal once Judge Gonzalez Rogers issues her final ruling. But reversing a unanimous jury finding is a high bar. For markets, the immediate read is straightforward: the legal risk cloud over OpenAI's IPO has lifted. Microsoft's stock moved on the news as investors priced out a liability that had been hanging over both companies.
