Elon Musk vs. Sam Altman: The OpenAI Trial That Could Rewrite the Rules of AI

After years of legal sparring, Elon Musk and Sam Altman are finally heading to trial this week in Northern California. And this isn’t just another tech feud — the outcome could reshape OpenAI’s future, including its highly anticipated IPO.

Musk is suing OpenAI, alleging that Altman and president Greg Brockman tricked him into funding the company in its early days by promising it would stay a nonprofit dedicated to AI for humanity’s benefit. Then, he claims, they flipped the script and built a for-profit subsidiary. Musk wants up to $134 billion in damages from OpenAI and Microsoft, and he’s asking the court to kick Altman and Brockman out and restore OpenAI to nonprofit status. Interestingly, he’s asking that any damages go to OpenAI’s nonprofit, not to him personally.

Nine jurors will deliver an advisory verdict — non-binding, but it’ll guide the judge. Musk, Altman, and Brockman will all take the stand. So will former OpenAI chief scientist Ilya Sutskever, former CTO Mira Murati, and Microsoft CEO Satya Nadella. Expect cringey texts, raw diary entries, and all the scheming that went into building the most hyped AI company in the world.

This trial is a rare chance to peek behind the curtain of an industry that usually operates in total secrecy. And the public record is about to get a lot more interesting.

What’s the fight about?

When OpenAI launched in 2015, it was a nonprofit backed by a $38 million donation from Musk. The mission: build open-source AI for everyone, no financial strings attached. But over time, the company argued that competition made it dangerous to share its models openly, and that a nonprofit couldn’t raise enough capital to keep up.

MIT Technology Review was first to report on OpenAI’s internal conflicts around this shift. The court has already found that by 2017, Altman and Brockman wanted to create a for-profit arm, while Musk wanted to merge OpenAI with Tesla. When Musk threatened to pull funding, Altman and Brockman assured him they’d stay nonprofit. Musk claims they secretly plotted the pivot anyway. OpenAI counters that Musk agreed a for-profit was necessary and even wanted to be CEO.

But here’s the thing: even if Musk proves he was misled, he may not have legal standing to sue over the restructuring. Some legal scholars are scratching their heads over why the judge let this claim proceed. “The idea that Elon Musk can sue because he was a donor or used to be on the board is pretty puzzling,” says Jill Horwitz, a law professor at Northwestern. “Typically, it’s up to the attorneys general to bring such a claim. And that’s already happened.”

In October 2025, California and Delaware attorneys general struck a deal with OpenAI to approve its new corporate structure, with conditions like a safety committee reviewing for-profit decisions. Critics, including Musk, safety advocates, and civil society groups, tried to block it. California’s AG declined to join Musk’s suit, saying they didn’t see how it served the public interest.

The real issue: Does OpenAI’s deal hold water?

Whether the AG deal actually locks OpenAI into its nonprofit mission is an open question. “Elon Musk should have to show what the deficiencies are in what’s been agreed to by OpenAI with the attorneys general,” says Rose Chan Loui of UCLA Law.

Musk’s argument has some traction with academics. Benjamin Means, another law professor, told MIT Technology Review that the AG deal “doesn’t protect the charitable purpose as well as it could.” He points out that the safety committee is controlled by the for-profit board, which raises questions about independence.

What’s at stake?

If Musk wins, OpenAI could be forced back to nonprofit status, which would upend its IPO plans and potentially oust Altman. If he loses, the company gets a green light to proceed with its for-profit structure — but the trial will still air a lot of dirty laundry.

Either way, this trial is a big deal for anyone watching the AI industry. It’s not just about OpenAI’s future; it’s about whether a company can start with a mission to benefit humanity and then quietly pivot to chasing profits without consequences.

I’ll be watching closely. The testimony from Sutskever, Murati, and Nadella could be explosive. And the texts and diaries? Pure gold for anyone who wants to understand how Silicon Valley really works.
