Elon Musk loses OpenAI suit

A federal jury in Oakland, California, ruled on May 18 that Elon Musk waited too long to sue OpenAI, ending a three-week trial over whether the company abandoned its original nonprofit mission. The verdict cleared OpenAI, Chief Executive Sam Altman, President Greg Brockman and Microsoft of liability in one of Silicon Valley’s most closely watched legal fights. A nine-person jury reached the decision in less than two hours, according to multiple reports. Musk said after the verdict that he would appeal. ### Why did the jury throw the case out? The jury’s answer was narrow: Musk’s claims were barred by the statute of limitations. Jurors found that he had sued too late over conduct he said transformed OpenAI from a nonprofit created for humanity’s benefit into a profit-driven business. That meant the panel did not need to decide the broader factual fight over whether Altman and other OpenAI leaders had broken any founding promise to Musk. Reuters and other outlets reported that the verdict turned on timing rather than the underlying dispute over OpenAI’s structure. ### What was Musk asking the court to do? Musk sought damages that some reports put at $150 billion, along with governance changes at OpenAI, including removing Altman from the board. His case argued that OpenAI’s leadership betrayed the organization’s original purpose after he helped found and finance it. Microsoft was also named because of its deep commercial relationship with OpenAI. OpenAI and Microsoft denied wrongdoing during the trial, and OpenAI argued there was never a binding promise to remain a nonprofit permanently. ### What came out during the trial besides the verdict? Three weeks of testimony put OpenAI’s internal history, financing and governance in public view. Coverage of the trial said witnesses and documents traced how the company moved from a research nonprofit into a company tied to multibillion-dollar commercial partnerships and infrastructure demands. Axios reported that the proceedings exposed a wider rivalry between Musk and Altman, who once worked together at OpenAI before becoming competitors in artificial intelligence. The trial also aired questions about who controls advanced AI systems, how nonprofit oversight works once large investors arrive, and how OpenAI’s relationship with Microsoft shaped its growth. ### Why did this matter for OpenAI right now? OpenAI entered the case facing the risk of a major financial judgment and potential disruption to its leadership structure. The verdict removed that immediate courtroom threat and allowed the company to avoid what Reuters described as an obstacle to an eventual initial public offering. The timing mattered because OpenAI has been expanding commercial partnerships and competing with Musk’s own AI company, xAI. The case therefore unfolded not just as a dispute about old promises, but during an active contest over talent, capital and influence in the AI industry. ### What did Musk say after losing? Musk said he would appeal the verdict and argued publicly that the case had not been decided on its merits. In posts after the ruling, he called the decision a precedent that could allow charities to be “looted,” according to reports on his reaction. His legal team also signaled the fight would continue. That keeps alive a public conflict that has stretched from boardroom disagreements and social media attacks into federal court. ### What happens next in court? An appeal would likely go to the U.S. Court of Appeals for the Ninth Circuit after post-trial motions in the district court. Judge Yvonne Gonzalez Rogers, who oversaw the case in Oakland, indicated after the verdict that reversing the jury’s decision on appeal could be difficult, according to reports. OpenAI, Altman, Brockman and Microsoft now move forward without this trial hanging over them, while Musk’s next formal step is to file his appeal papers. The case record from the May 2026 trial in federal court in Oakland will shape that next phase.
