Jury Rejects Elon Musk’s OpenAI Lawsuit in Major Win for Sam Altman

A California jury rejected Elon Musk’s lawsuit against OpenAI and CEO Sam Altman, handing a major legal victory to the ChatGPT maker after jurors concluded Musk waited too long to bring his claims. The case centered on Musk’s allegations that OpenAI abandoned its original nonprofit mission after accepting his early financial backing, but the jury unanimously found the claims had effectively expired.

Musk had argued that Altman misled him after he donated $38 million to OpenAI during its early years. According to Musk, the company later shifted toward a for-profit structure that contradicted its founding commitment to develop artificial intelligence for the benefit of humanity rather than commercial gain.

The trial offered a rare public look into the history of one of the AI industry’s most influential companies. Over three weeks, jurors reviewed internal communications and heard testimony from Musk, Altman, Microsoft CEO Satya Nadella, and other technology executives tied to OpenAI’s growth and corporate structure. Musk also accused Microsoft of helping OpenAI evolve into a more commercially driven business, though those claims were later dismissed after the jury ruled against Musk on the core allegations involving OpenAI itself.

Jurors reportedly deliberated for only a short period before reaching their decision, underscoring how heavily the case hinged on timing rather than broader questions surrounding OpenAI’s mission or corporate direction. Carl Tobias, chair at the University of Richmond School of Law, described the outcome as “a very fact-based decision,” adding that juries bring “the common sense of the community to resolve factual disputes.”

During testimony, Musk framed the lawsuit as a defense of charitable principles and argued that OpenAI violated the spirit of its founding structure. “It’s actually very simple,” Musk testified. “It’s not OK to steal a charity… If it’s okay to loot a charity, the entire foundation of charitable giving will be destroyed.”

Altman challenged that narrative directly in court. He told jurors that Musk had previously supported the idea of OpenAI becoming a for-profit organization and had sought greater control over the company himself. “A particularly hair-raising moment was when my co-founders asked, ‘If you have control, what happens when you die?’” Altman testified. “He said something like, ‘maybe it should pass to my children.’”

The conflict traces back to OpenAI’s founding in 2015, when Musk helped launch the organization alongside Altman and other tech leaders. Musk eventually left the company after disputes over leadership and control. In the years that followed, OpenAI’s rise — fueled largely by the explosive success of ChatGPT — turned Altman into one of the most prominent figures in artificial intelligence while deepening the public feud between the two former collaborators.

As OpenAI’s influence expanded, Musk increasingly criticized the company online and questioned whether it had abandoned its original mission. OpenAI responded publicly to some of those accusations in 2024 with a detailed blog post laying out its version of the company’s history and governance decisions.

Following the verdict, OpenAI spokesman Sam Singer described the outcome as a “tremendous victory” outside the Oakland courthouse and argued the lawsuit was “nothing but an effort by Mr Musk to slow down a competitor.” William Savitt, the company’s lead attorney during the trial, said the claims “bear no relationship with reality” and argued the jury rejected Musk’s account of the company’s origins.

Despite the loss, Musk’s legal team signaled the dispute is likely not over. Attorney Steven Molo told the judge he wanted to preserve Musk’s right to appeal, while lawyer Marc Toberoff later told reporters, “This war is not over, and I’d sum it up in one word, appeal.”

Legal experts say overturning the verdict could be difficult because appeals courts are generally reluctant to reverse highly fact-specific jury findings. Tobias noted that appellate judges are unlikely to second-guess a unanimous jury decision that was also supported by the trial court.

The ruling arrives during a broader debate over how powerful AI companies should balance public-interest goals with commercial growth. OpenAI’s transformation from a nonprofit research lab into one of the most valuable AI firms in the industry has become a central flashpoint in ongoing discussions about governance, control, and accountability in the race to develop advanced artificial intelligence.
