Jury Verdict: Claims Barred by Timing
On May 18, 2026, a nine-member federal jury in Oakland issued a unanimous advisory verdict that Elon Musk’s suit against OpenAI, CEO Sam Altman, president Greg Brockman, and Microsoft was barred by the statute of limitations. The jury deliberated under two hours, and Judge Yvonne Gonzalez Rogers adopted the finding and dismissed all claims.
Background and Key Players
OpenAI was founded in 2015 as a nonprofit AI lab by Musk, Altman, Brockman, Ilya Sutskever and others, pledging to develop safe AI for humanity. Musk contributed about $38 million, left the board in 2018, and the organization created a capped for-profit subsidiary in March 2019, later receiving a multibillion-dollar investment from Microsoft. Musk sued in August 2024, alleging breach of the nonprofit charter, unjust enrichment, and Microsoft’s alleged aid.
Timeline of the Dispute
- 2015-2017: Musk funds OpenAI ($38 M).
- 2018: Musk departs board.
- 2019: OpenAI launches for-profit arm.
- Aug 2021: Jury later found Musk aware of shift.
- Aug 2024: Lawsuit filed.
- Apr-May 2026: Three-week trial in Oakland.
- May 18, 2026: Verdict and judicial adoption.
Core Data
- Jury: nine members, unanimous.
- Deliberation: < 2 hours.
- OpenAI valuation at trial: $852 billion-$1 trillion.
- Microsoft’s reported investment: $13 billion (some reports cite $100 billion in partnership revenue).
- Damages sought by Musk: $134-$150 billion (sources vary).
Impact on AI Landscape
The ruling leaves OpenAI’s corporate structure unchanged, clearing the way for a planned IPO that could exceed $1 trillion. It also highlights the procedural risk of delayed litigation in charitable-trust disputes, a precedent for future tech-sector governance battles.
Official Statements
Judge Rogers said she was “prepared to dismiss on the spot” given the evidence. OpenAI’s counsel called the suit “sour grapes” aimed at a competitor. Microsoft’s spokesperson said the facts were “clear” and welcomed the dismissal. Musk’s lawyer Steven Molo reserved the right to appeal, noting the challenge would be uphill.
Criticism and Opposition
Legal analysts and OpenAI officials said the case was driven by Musk’s rivalry with his AI venture xAI, not genuine charitable concerns. They noted his prior support for a for-profit model and framed the suit as an attempt to hinder OpenAI’s growth.
Conflicting Reports
Sources differ on the damages figure—$134 billion, $150 billion, or $130 billion—and on Microsoft’s involvement, citing either a $13 billion investment or $100 billion in partnership revenue. The advisory verdict left the merits of the allegations untested.
