Elon Musk vs. Sam Altman: The OpenAI Trial That Could Reshape AI’s Future

Elon Musk and Sam Altman are finally going to trial this week in Northern California, and the stakes couldn’t be higher. After years of legal posturing, a jury will decide whether OpenAI can exist as a for-profit entity ahead of its highly anticipated IPO. The court could even oust Altman and president Greg Brockman from their roles.

Musk is suing OpenAI, claiming Altman and Brockman tricked him into funding the company’s early days by promising it would stay a nonprofit dedicated to benefiting humanity. He left in 2018 after a bitter power struggle, and now he’s seeking up to $134 billion in damages from OpenAI and Microsoft, one of its biggest backers. He wants the court to strip Altman and Brockman of their positions and force OpenAI back to nonprofit status. Notably, Musk isn’t asking for the money himself—he wants any damages awarded to OpenAI’s nonprofit arm.

Nine jurors will deliver an advisory verdict, which isn’t binding but will guide the judge. Musk, Altman, and Brockman will all testify. So will former OpenAI chief scientist Ilya Sutskever, ex-CTO Mira Murati, and Microsoft CEO Satya Nadella. Expect cringey texts, raw diary entries, and endless scheming to come to light. In an industry that usually operates in secrecy, this trial is a rare chance to peek behind the curtain.

What’s the actual fight about?

When OpenAI launched in 2015 as a nonprofit, backed by a $38 million donation from Musk, it promised open-source technology for the public good. No financial returns required. But over time, the company argued that intense competition made sharing its AI models dangerous, and that a nonprofit structure couldn’t raise enough capital. (MIT Technology Review was first to report on the internal conflicts around this shift.)

The court has already found that in 2017, Altman and Brockman wanted to create a for-profit arm, while Musk proposed merging OpenAI with Tesla. When Musk threatened to stop funding, they assured him they’d keep it nonprofit. Musk alleges they then pursued the for-profit pivot behind his back. OpenAI counters that Musk agreed a for-profit entity was necessary and even wanted to be CEO.

But here’s the thing: even if Musk proves he was misled, he might not have legal standing to sue over the restructuring. Some legal scholars are baffled 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 Northwestern law professor specializing in nonprofit law. “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 under conditions like a safety committee reviewing for-profit decisions. Critics—including Musk, AI safety advocates, and civil society groups—tried to stop it. California’s AG declined to join Musk’s lawsuit, saying it didn’t serve the public interest.

Whether that deal actually holds OpenAI to 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, director of the UCLA School of Law’s nonprofit program.

Why this trial matters beyond the drama

This isn’t just about Musk’s bruised ego or Altman’s ambitions. The outcome could set a precedent for how AI companies balance profit and public benefit. OpenAI’s IPO is on the line, and if the court forces it back to nonprofit status, it could cripple its ability to raise the billions needed to compete with Google and Meta. On the flip side, letting it go full for-profit might accelerate the trend of AI development being driven by shareholder returns rather than societal good.

I’ve been watching this case since it started, and what strikes me is how little has changed since the early days. Musk’s complaint reads like a breakup letter: he funded the dream, got pushed out, and now wants to burn it all down. Altman and Brockman, meanwhile, look like they’re trying to have it both ways—claiming altruism while chasing unicorn valuations.

Neither side is clean. Musk’s own record on AI safety is mixed at best, and his Tesla AI ambitions are hardly pure. OpenAI’s pivot from open-source to closed-source was inevitable given the capital requirements, but the way they handled it was sloppy and deceptive. The trial will likely reveal just how messy the founding was—and how little the original mission mattered once the money got big.

Ultimately, the judge will decide, not the jury. But the public testimony could shift the narrative. If Musk can prove Altman lied to him, it’ll damage OpenAI’s credibility. If he can’t, it’ll look like a billionaire throwing a tantrum. Either way, we’ll learn more about the sausage-making of AI’s most hyped company.

One thing’s for sure: the days of AI companies getting a free pass on transparency are numbered. This trial is a sign that the public, and the courts, are starting to demand answers.
