Elon Musk Loses Lawsuit Against Sam Altman and OpenAI
A Nine-Person Jury Unanimously Rules His Claims Were Filed Too Late
May 18, 2026 – 5:53 pm
A nine-person jury in Oakland has unanimously found that Elon Musk’s lawsuit against Sam Altman and OpenAI was filed too late, ending the trial without reaching the merits. This decision is based on statute of limitations grounds, clearing a significant legal hurdle for OpenAI’s IPO path.
The Verdict:
Elon Musk has lost his legal battle against Sam Altman, Greg Brockman, OpenAI, and Microsoft. The advisory verdict, if adopted by Judge Yvonne Gonzalez Rogers, signifies that Musk’s attempts to remove Altman from OpenAI, unwind the company’s restructuring, and seek substantial disgorgement are unlikely to succeed.
Key Findings:
- Statute of Limitations: The jury concluded that Musk’s claims were filed outside the statutory time limit. He left OpenAI’s board in 2018 but did not file suit until February 2024, a gap of six years.
- Public Knowledge: OpenAI argued that Musk knew or should have known about the alleged misconduct, including Microsoft’s investments and the creation of a for-profit subsidiary, well within the filing period. The jury agreed.
- Uniform Verdict: All nine jurors found that the harms Musk alleged occurred prior to the deadline for his claims, making his lawsuit untimely.
What Was at Stake:
This trial had been considered a pivotal moment in AI governance, with potential implications for the future of OpenAI and the broader tech industry. The outcome prevents Musk from pursuing his claims on merit, focusing instead on the timing of his legal action.
