Musk Loses $150 Billion Lawsuit Against OpenAI: Jury Rejects All Claims
On May 18, 2026, a federal jury in Oakland, California, unanimously rejected all of Elon Musk's claims against OpenAI, Sam Altman, and Greg Brockman in what was called "the most expensive lawsuit in AI history."
What Happened
The verdict came after just six hours of deliberation. The jury concluded Musk had exceeded the three-year statute of limitations. Judge Yvonne Gonzalez Rogers accepted the findings and dismissed the case on the spot, stating there was "substantial evidence" that Musk knew about OpenAI's for-profit transition well before filing suit in 2024.
The defense presented internal emails from 2018 and 2019 showing Musk discussing the corporate restructuring with Altman.
Context and Background
Musk co-founded OpenAI in 2015 and invested ~$50M. He left the board in 2018 citing conflicts with Tesla AI projects. In 2019, OpenAI created a for-profit subsidiary attracting $13B from Microsoft. Musk filed suit in February 2024 — nearly five years later. Meanwhile, he founded xAI and launched Grok as a ChatGPT competitor.
Impact on People
| Aspect | If Musk Won | Current Outcome | Real Impact |
|---|---|---|---|
| OpenAI structure | Possible nonprofit return | Maintains hybrid model | Investments continue |
| AI development | Potential slowdown | Accelerated pace maintained | GPT-5 on schedule |
| Regulation | Precedent to limit AI profit | No regulatory impact | Status quo maintained |
What Those Involved Are Saying
Sam Altman: "The jury saw the evidence and made the right call. Now we get back to the work that matters most."
Musk on X: "A calendar technicality prevented the jury from examining the real merits. We will appeal."
Conclusion
Musk's defeat closes a dramatic chapter in AI history but doesn't resolve the central question: when technology with civilization-changing potential is developed with public money, who should control its fruits?
