California judge dismisses Elon Musk’s OpenAI lawsuit over statute of limitations

Elon Musk has lost his latest legal fight with OpenAI, after a California jury said he waited too long to sue over the company’s shift from a nonprofit mission toward a for-profit structure. The nine-person advisory jury in Oakland unanimously found that Musk’s claims were filed outside the statute of limitations, and Judge Yvonne Gonzalez Rogers accepted that finding and dismissed the case, according to reports from CBS News, ABC News and TechCrunch.

The ruling is a major win for OpenAI and its chief executive, Sam Altman, because it ends a three-week trial without the court reaching the deeper question at the heart of Musk’s complaint: whether OpenAI abandoned its original public-benefit mission. Musk had sued for more than $150 billion in damages and also sought to remove Altman and OpenAI President Greg Brockman from leadership. Microsoft, which has a major partnership with OpenAI, was also named as a defendant.

According to the reporting, the jury did not decide the case on the merits. Instead, it concluded that Musk had missed the legal deadline to bring his claims. OpenAI argued that any harm Musk complained about happened before August 2021, making the 2024 lawsuit too late. After the verdict, Musk said on X that the court had not ruled on the substance of his allegations and called the outcome a “calendar technicality,” adding that he plans to appeal.

The trial also underscored a central tension in Musk’s case, as TechCrunch noted: Musk has long accused OpenAI of betraying a nonprofit promise, but evidence at trial highlighted that he himself had once pushed for OpenAI to be folded into Tesla, which would have moved the venture into a for-profit setup. That detail complicated his argument that OpenAI’s business shift was uniquely improper.

Beyond the courtroom, the case matters because it touches one of the biggest questions in artificial intelligence: who controls the industry’s most powerful systems, and whether companies founded with a public-interest mission can legally turn into highly valued commercial businesses. OpenAI is now valued at hundreds of billions of dollars and remains closely tied to Microsoft, while Musk’s own AI company, xAI, competes directly with it.

For Musk, the loss is another setback in a pattern of high-profile legal and business battles. As the BBC reported, he is unlikely to change his combative approach, even after a defeat that leaves OpenAI free to continue its restructuring efforts for now. The appeal process could extend the fight, but for the moment, the court has ended Musk’s challenge on procedural grounds rather than on the question of whether OpenAI broke its founding promise.
