Sam Altman’s credibility on trial: Equity, board firing, and the future of OpenAI’s mission

In a California federal courtroom on Tuesday, OpenAI CEO Sam Altman faced a withering cross-examination that tested not just his memory, but his credibility. The interrogation, led by attorney Steve Molo representing Elon Musk, centered on whether Altman misled the U.S. Senate in May 2023 about his financial interest in OpenAI, and whether his influence over the company has effectively neutralized the non-profit board meant to oversee it.

Altman’s Senate testimony revisited

During a Senate hearing on AI regulation in May 2023, Senator John Kennedy of Louisiana pressed Altman on whether he had equity in OpenAI. Altman replied, “No, I’m paid enough for health insurance, I have no equity in OpenAI.” That statement, while technically accurate, omitted his economic exposure through a limited partner position in a Y Combinator fund that held OpenAI shares. Under oath on Tuesday, Altman acknowledged the omission but insisted it was not intentional. “I didn’t mention it in that testimony, but, again, I think it is well understood of what it means to be a passive owner of many venture funds,” Altman said. Molo pressed further: “You thought Senator Kennedy was a very sophisticated investor when he asked you that question?”

The board firing and the question of control

A central issue in the trial is whether OpenAI’s non-profit board can genuinely control the for-profit entity that operates its AI models. In November 2023, the board briefly fired Altman and president Greg Brockman, citing a lack of candor. Former board members Helen Toner and Tasha McCauley testified that Altman had misled them, with McCauley describing “a toxic culture of lying.” Altman has disputed that characterization, telling the court, “I do have doubts that was the full reason” for his firing. The board reinstated Altman days later after a near-universal employee revolt, raising questions about whether any board could realistically discipline or remove him. Asked if he would ever fire himself, Altman replied, “I have no plans to do so.”

Why this matters for AI governance

The trial is not merely a personal dispute between Musk and Altman. It tests the legal and structural viability of a non-profit controlling some of the world’s most powerful AI models. If the court finds that Altman’s influence renders the board powerless, it could force OpenAI to restructure, potentially affecting its governance, mission, and partnerships with Microsoft and others. The outcome could set a precedent for how AI companies balance profit motives with safety and public accountability.

Witnesses split on Altman’s character

Microsoft CEO Satya Nadella testified that Altman’s firing was “amateur city,” while current OpenAI board chair Bret Taylor said he found no grounds for termination and described Altman as “forthright with me.” Dr. Zeko Kolter, an OpenAI board member focused on AI safety, said no one had interfered with his work since joining in 2024. But Taylor also acknowledged that Altman’s reinstatement was driven by the threat of mass employee departure, not a reversal of the board’s concerns. The jury and Judge Yvonne Gonzalez Rogers must weigh whether the current structure genuinely fulfills OpenAI’s original mission or whether it has become a vehicle for Altman’s personal vision.

Conclusion

The trial is expected to continue for several weeks, with closing arguments likely in late June. The court’s decision on whether to grant Musk’s request to shut down OpenAI’s for-profit operations will have ripple effects across the AI industry. For now, Altman’s credibility remains the central question, and his own words may be the most damaging evidence against him.
