Musk Loses OpenAI Lawsuit — Jury Finds Claims Time-Barred, Clearing AI's Biggest Legal Threat
A California federal jury dismissed Musk's lawsuit against OpenAI, finding his claims time-barred. The ruling clears the biggest legal obstacle to OpenAI's $850 billion IPO.
- A California federal jury dismissed Musk's OpenAI lawsuit on statute of limitations grounds, clearing the biggest legal obstacle to OpenAI's IPO
A California federal jury dismissed Elon Musk's lawsuit against OpenAI, finding his claims time-barred. The ruling removes the biggest legal risk hanging over OpenAI's IPO ambitions.
Elon Musk lost his lawsuit against OpenAI. On May 18, 2026, a nine-person federal jury in Oakland, California ruled that Musk's claims were barred by the statute of limitations. Judge Yvonne Gonzalez Rogers accepted the jury's advisory verdict and dismissed the case.
Three-Week Trial Ends With "Time-Barred" Verdict
Musk filed the lawsuit in 2024, alleging that OpenAI abandoned its nonprofit founding mission by pursuing commercial expansion backed by billions of dollars from Microsoft (MSFT), Amazon (AMZN), and SoftBank. He argued the transformation violated the original founding agreement.
The jury rejected his core argument. Because Musk made his last $38 million contribution to OpenAI in 2019-2020, the statute of limitations had already expired by the time he filed in 2024. CEO Sam Altman and co-founder Greg Brockman both testified during the three-week trial.
"This was a hypocritical attempt to sabotage a competitor by someone who tried to take control of OpenAI and failed."

What a Musk Win Would Have Meant
Had Musk prevailed, the consequences for OpenAI would have been severe. A court order reverting OpenAI to nonprofit status could have triggered:
- Cancellation of OpenAI's IPO — currently valued at $850 billion
- Unwinding of billions in investments from Microsoft, Amazon, and SoftBank
- Legal threat to GPT-4o and o3 subscription revenue models
- Collapse of OpenAI's race to IPO before Anthropic
OpenAI issued no public statement following the verdict. Musk's team did not immediately announce plans to appeal.
IPO Path Cleared
The ruling is a direct positive for OpenAI's public listing timeline. OpenAI recently secured a $40 billion investment from SoftBank at an $850 billion valuation. With the lawsuit risk eliminated, major investment banks are expected to accelerate IPO preparations.
Musk has positioned xAI — the company behind the Grok model series — as a direct OpenAI competitor. The court defeat effectively closes the legal front of his campaign to undermine OpenAI.
Frequently Asked Questions
Why did the jury dismiss Musk's claims?
Musk filed his lawsuit in 2024, but his last contribution to OpenAI ($38 million) was made in 2019-2020. The jury found his claims were barred by the statute of limitations, meaning he waited too long to sue.
What would have happened if Musk had won?
A court could have ordered OpenAI reverted to nonprofit status, potentially unwinding billions in investments from Microsoft, Amazon, and SoftBank, and derailing OpenAI's IPO plans entirely.
What is OpenAI's current valuation?
OpenAI was most recently valued at $850 billion following a $40 billion investment from SoftBank.
How does this ruling affect OpenAI's IPO?
The dismissal removes the largest legal obstacle to OpenAI going public. The company has been racing to IPO before rival Anthropic, and investment banks are expected to accelerate IPO preparations now that the lawsuit risk is gone.
Can Musk appeal the verdict?
An appeal is legally possible, but Musk's team did not announce immediate plans to do so. Statute of limitations rulings are based on factual findings and are difficult to overturn on appeal.
