Musk Takes Stand Against Altman in $134B OpenAI Trial

Elon Musk testified Tuesday as the first witness in his high-stakes lawsuit against OpenAI CEO Sam Altman, seeking up to $134 billion in damages and the removal of OpenAI’s leadership. The trial, which began with jury selection on April 27th, could fundamentally reshape the AI industry’s most valuable startup and determine whether OpenAI can continue operating as a for-profit enterprise.

According to MIT Technology Review, Musk alleges that Altman and OpenAI president Greg Brockman deceived him into funding the company by promising to maintain it as a nonprofit dedicated to developing AI for humanity’s benefit, only to later restructure as a for-profit subsidiary.

The Core Legal Claims

Musk’s lawsuit centers on OpenAI’s transformation from its 2015 nonprofit origins to its current hybrid structure. The Verge reported that Musk filed the lawsuit in 2024, accusing OpenAI of abandoning its founding mission of developing AI to benefit humanity in favor of profit maximization.

The Tesla CEO cofounded OpenAI with Altman and others in 2015 but left in 2018 after what MIT Technology Review described as “a bitter power struggle.” Musk invested tens of millions of dollars in OpenAI’s early development, expecting the company to remain true to its nonprofit charter.

Musk is demanding the court remove both Altman and Brockman from their leadership roles and restore OpenAI as a nonprofit organization. Notably, he has asked that any damages be awarded to OpenAI’s nonprofit arm rather than to himself personally.

OpenAI’s Defense Strategy

OpenAI has dismissed the lawsuit as a competitive attack rather than a legitimate legal claim. In a statement on X, the company said “This lawsuit has always been a baseless and jealous bid to derail a competitor” aimed at boosting Musk’s own AI ventures through SpaceX, xAI, and X, which have launched Grok as a ChatGPT competitor.

The company argues that Musk’s departure in 2018 stemmed from his inability to gain control over OpenAI’s direction, not from any deception about the company’s mission. OpenAI maintains that its hybrid structure allows it to pursue its original goals while securing the massive funding required for advanced AI development.

Key Witnesses and Evidence

The trial will feature testimony from major figures in the AI industry. MIT Technology Review noted that Altman, Brockman, former OpenAI chief scientist Ilya Sutskever, former CTO Mira Murati, and Microsoft CEO Satya Nadella are all expected to take the stand.

Nine jurors will deliver an advisory verdict to guide the judge’s final decision on Musk’s claims. The proceedings are expected to reveal private communications, internal documents, and behind-the-scenes details about OpenAI’s founding and evolution that have never been made public.

Musk has also amplified external criticism of Altman during the trial. Wired reported that Musk boosted a New Yorker investigation into Altman’s allegedly deceptive behavior on X, writing “Calling him ‘Scam’ Altman is accurate.”

Potential Industry Impact

The trial’s outcome could have sweeping consequences for OpenAI and the broader AI industry. A ruling in Musk’s favor could force OpenAI to restructure its business model ahead of its highly anticipated IPO, potentially disrupting its partnerships with Microsoft and other investors.

The case also raises fundamental questions about how AI companies balance profit motives with their stated missions to benefit humanity. OpenAI’s success with ChatGPT has made it the most valuable AI startup, but its transition from nonprofit to for-profit has drawn scrutiny from researchers and policymakers.

If Musk succeeds in his bid to restore OpenAI as a nonprofit, it could set a precedent affecting other AI companies that have adopted similar hybrid structures. The $134 billion in damages Musk is seeking would represent one of the largest corporate legal settlements in history.

Microsoft’s Role in the Dispute

Microsoft, which has invested over $13 billion in OpenAI, is also named as a defendant in Musk’s lawsuit. The tech giant’s partnership with OpenAI has been central to both companies’ AI strategies, with Microsoft integrating OpenAI’s models into its Office suite and Azure cloud services.

The trial could expose details about Microsoft’s agreements with OpenAI and whether the partnership influenced the company’s shift away from its nonprofit mission. Microsoft CEO Satya Nadella’s testimony will likely focus on the business rationale behind the tech giant’s massive investment in OpenAI.

What This Means

This trial represents a critical inflection point for the AI industry’s most influential company. The legal battle between two of tech’s most prominent figures could reshape how AI companies structure themselves and pursue their missions. For OpenAI, the stakes couldn’t be higher — the company faces potential leadership changes, business model disruption, and massive financial damages just as it prepares for a public offering that could value it at over $100 billion.

The case also highlights the tension between AI companies’ lofty promises to benefit humanity and their need for massive capital to compete in the AI arms race. Regardless of the outcome, the trial will likely influence how future AI companies balance nonprofit missions with commercial success.
