Elon Musk testified for over three hours in the ongoing trial where he accuses OpenAI and CEO Sam Altman of betraying the company's founding nonprofit mission by converting to a for-profit structure.

Elon Musk testified on the second day of his lawsuit against OpenAI and its CEO Sam Altman, accusing them of betraying the company's original nonprofit mission by shifting to a for-profit model. Musk stated that he contributed $38 million to OpenAI, which he founded as a nonprofit in 2015 alongside Altman and Greg Brockman to develop artificial intelligence for public good.

He seeks to force OpenAI back to nonprofit status and demands the return of alleged ill-gotten gains estimated at $150 billion. OpenAI's lawyer William Savitt cross-examined Musk, leading to tense exchanges where Musk accused Savitt of trying to trick him with questions.

Musk confirmed he did not fulfill a promised $1 billion donation, citing lost confidence in the team. The trial, which began on Monday in a federal courthouse in Oakland, California, is presided over by Judge Yvonne Gonzalez Rogers.

Musk left OpenAI's board in 2018 after disagreements, including proposals to merge the company with Tesla. Sources indicate Musk emailed OpenAI leadership in early 2018 suggesting that merging with Tesla was necessary to compete with Google DeepMind.

OpenAI later added a for-profit entity and raised $122 billion in a recent funding round, with Microsoft as a major investor and co-defendant in the lawsuit. Altman and Brockman are named in the suit, along with Microsoft. Musk testified that OpenAI's shift allowed its leaders to enrich themselves improperly from what was intended as a charity.

OpenAI argues that Musk insisted on a for-profit path himself and left when he could not gain control.

It’s very simple. The judge intervened at one point, asking both parties to calm down. Musk described himself as having provided initial control but planning to lose majority stake quickly, emphasizing the nonprofit intent for public good. OpenAI's side highlighted Musk's formation of xAI as a for-profit rival in 2023, suggesting his lawsuit is motivated by competition. Musk responded that he created xAI because OpenAI deviated from its mission. The trial has revealed internal communications, including texts showing Musk's ongoing interest in OpenAI through former board member Shivon Zilis. She also admonished Musk and Altman for their social media posts about the trial, asking them to limit such activity.

The lawsuit stems from 2015 concerns that corporate greed at firms like Google DeepMind could hinder safe AI development. Musk and Altman founded OpenAI as a nonprofit to counter this, but divisions led to Musk's departure and the creation of rivals like xAI and Anthropic.

OpenAI completed a corporate restructuring in October, moving to a traditional for-profit structure overseen by a nonprofit foundation. Musk's demands include removing Altman from the board and redirecting profits to a charitable trust.

Mr. Musk’s lawsuit is a pageant of hypocrisy.

External experts, as reported in sources, indicate Musk is unlikely to win all remedies, given evidence that he previously advocated for a for-profit model. The case highlights tensions between profit motives and societal benefits in AI development.

The trial has exposed personal animosities, with Musk calling Altman 'Scam Altman' on social media and Altman describing Musk as insecure. It also references Musk's alleged ketamine use during negotiations, though the judge ruled it irrelevant. Similar schisms have shaped the AI landscape, including Anthropic's formation by former OpenAI employees and Meta's investments in AI to compete.

The outcome could influence governance structures in the industry, where leaders like Musk, Altman, and Dario Amodei control major AI firms.
