A Jury Took 90 Minutes to End Elon Musk's $150 Billion War With OpenAI

Elon Musk just lost the biggest AI lawsuit in history, and it was not even close. A nine-member federal jury in Oakland, California, took roughly 90 minutes on Monday to unanimously reject every claim Musk brought against OpenAI and CEO Sam Altman. The case that was supposed to reshape the future of artificial intelligence ended with a verdict so fast the courtroom barely had time to settle in.

Here is the short version. Musk cofounded OpenAI back in 2015 and donated around $38 million to get it off the ground. The original pitch was simple: build powerful AI as a nonprofit, keep it open, and make sure no single company could monopolize the technology. Then OpenAI created a for-profit arm, struck a multibillion-dollar deal with Microsoft, and became the most valuable AI company on the planet.

Musk sued in February 2024, claiming Altman and president Greg Brockman had stolen a charity and enriched themselves at everyone else's expense. He wanted $150 billion in damages. He wanted the court to force OpenAI back into a nonprofit structure. He wanted to blow the whole thing up.

The jury said no. Not because they weighed the merits of the nonprofit argument and disagreed. They said Musk simply waited too long to file. California has a three-year statute of limitations for these kinds of claims, and the evidence showed that discussions about creating a for-profit entity started as early as 2017. Altman sent Musk documents in 2018 outlining plans to raise billions through a for-profit structure. Musk did not sue until six years later.

That is the part that stings the most if you are in the Musk camp. The case was not decided on whether OpenAI did something wrong. It was decided on the calendar. The jury never got to rule on the substance of the complaint because the clock had already run out.

The trial itself was a spectacle. Hundreds of pages of private emails, text messages, and internal meeting notes were entered into evidence. Greg Brockman's personal diaries were read aloud. OpenAI cofounder Ilya Sutskever testified. So did Shivon Zilis, who works for Musk's companies and is the mother of four of his children. At one point, text messages between Musk and Mark Zuckerberg surfaced, showing the two had discussed possibly buying OpenAI together.

OpenAI's lawyers had a devastating counterargument. They showed evidence that Musk himself had pushed for a for-profit structure at various points. He wanted OpenAI to compete with Google, and he understood that took real money — the kind nonprofits cannot raise. When Musk failed to gain control of the for-profit entity, he walked away. Then he started his own AI company, xAI, and sued the one he left behind.

Musk's lead attorney, Marc Toberoff, called the verdict a travesty and announced an immediate appeal to the Ninth Circuit. That process will take 12 to 18 months, with oral arguments likely landing in mid-to-late 2027. So this fight is not technically over. But the appeal will face an uphill climb — overturning a unanimous jury finding on statute of limitations is one of the hardest things to do in federal court.

For OpenAI, the verdict removes the single biggest legal cloud hanging over the company. Before the trial, that $150 billion claim was the largest overhang on OpenAI's path to going public. The company has been racing toward a valuation north of $850 billion, and with this lawsuit dismissed, the IPO timeline just moved up significantly.

For Musk, the loss underscores a broader problem. Rather than strengthening his position in the AI industry, the trial mostly highlighted the weaknesses of xAI, the company he built to compete with OpenAI. SpaceX acquired xAI earlier this year at a reported $250 billion valuation — impressive on paper, but still a fraction of OpenAI's. Musk is the richest person on the planet, but in the AI race, he is playing from behind.

The bigger question this case raised — whether it is okay for a nonprofit AI lab to transform into a for-profit juggernaut — did not get answered. The jury never weighed in on the ethics or legality of that shift. They only said Musk filed too late to challenge it. That means the precedent many people were hoping for, a ruling that would set boundaries around how AI organizations can restructure, still does not exist.

This matters because the nonprofit-to-for-profit pipeline in AI is not unique to OpenAI. Several AI labs started with idealistic missions and open research before pivoting toward commercial products and closed models. The tension between building AI for the public good and building it for shareholder value is the defining tension of this industry. This trial was supposed to test that tension in court. Instead, it tested the statute of limitations.

There is a real lesson here for anyone watching the AI industry closely. The time to challenge how these companies are structured is when the restructuring happens, not years later after the money has been made. Musk knew about the for-profit plans in 2018. He had standing to object then. He did not. By the time he filed suit, the legal window had closed even if the moral argument had not.

The grounded takeaway: the most dramatic AI lawsuit ever filed just ended with a whimper, not a bang. Musk lost on a technicality, OpenAI cleared its biggest legal hurdle, and the fundamental question of who AI should serve — the public or shareholders — remains unanswered. If that question matters to you, do not wait for a courtroom to settle it. The decisions being made right now, about how AI companies are built and who controls them, are the ones that will stick.
