Musk vs Altman Trial Begins as OpenAI Faces $134B Lawsuit

Elon Musk and Sam Altman began their high-stakes court battle on April 27th in Northern California, with Musk seeking up to $134 billion in damages and demanding the removal of OpenAI’s leadership. The trial could fundamentally reshape OpenAI’s corporate structure and potentially derail its planned IPO.

According to MIT Technology Review, nine jurors will deliver an advisory verdict to guide the judge in deciding Musk’s claims against Altman, OpenAI president Greg Brockman, and Microsoft. The Verge reported that Musk took the stand Tuesday as the first witness, portraying his involvement in founding OpenAI as “an effort to help save humanity.”

The Core Legal Claims

Musk alleges that Altman and Brockman deceived him into bankrolling OpenAI in its early days by promising to maintain it as a nonprofit dedicated to developing AI that benefits humanity. The lawsuit claims the company later restructured to operate a for-profit subsidiary, abandoning its founding mission.

Musk cofounded OpenAI with Altman and others in 2015 but left in 2018 after what MIT Technology Review described as “a bitter power struggle.” Court documents show Musk invested tens of millions of dollars in the company during its nonprofit phase.

The Tesla CEO is seeking the removal of Altman and Brockman from their leadership roles and wants OpenAI restored as a nonprofit organization. Notably, Musk has asked the court to award any damages to OpenAI’s nonprofit arm rather than to him personally.

OpenAI’s Defense Strategy

OpenAI has dismissed the lawsuit as baseless retaliation. In a statement on X, the company said: “This lawsuit has always been a baseless and jealous bid to derail a competitor” designed to boost Musk’s own AI ventures including xAI and its Grok chatbot.

The company argues that Musk’s departure in 2018 stemmed from his desire for control rather than principled disagreements about OpenAI’s mission. OpenAI’s legal team is expected to present evidence that the for-profit structure was necessary to secure the massive funding required for AI development.

Microsoft, which has invested billions in OpenAI and is also named in the lawsuit, faces potential liability for its role in the company’s transformation from nonprofit to hybrid structure.

Key Witnesses and Expected Testimony

The trial will feature testimony from tech industry heavyweights beyond Musk and Altman. Former OpenAI chief scientist Ilya Sutskever, former CTO Mira Murati, and Microsoft CEO Satya Nadella are expected to take the stand.

MIT Technology Review noted that “cringey texts, raw diary entries, and endless scheming behind the founding and growth of OpenAI are expected to come to light.” These revelations could provide unprecedented insight into the internal dynamics that shaped one of the world’s most valuable AI companies.

The timing coincides with increased scrutiny of Altman’s leadership. Wired reported that Musk boosted a New Yorker investigation into Altman’s allegedly deceptive behavior on X, writing “Calling him ‘Scam’ Altman is accurate.”

Broader Implications for AI Industry

The trial’s outcome could establish precedent for how AI companies balance commercial interests with stated humanitarian missions. OpenAI’s transformation from nonprofit to for-profit hybrid has been closely watched by other AI startups considering similar structures.

A ruling in Musk’s favor could force OpenAI to restructure ahead of its planned IPO, potentially valuing the company at over $100 billion. The case also highlights tensions between AI safety advocates who favor nonprofit models and investors seeking commercial returns.

The lawsuit comes as OpenAI faces increasing competition from Musk’s xAI, Google’s Gemini, and Anthropic’s Claude models. Any disruption to OpenAI’s leadership or business model could accelerate market share shifts in the rapidly evolving AI landscape.

What This Means

This trial represents more than a personal dispute between two tech billionaires — it could define how AI companies structure themselves and honor their founding commitments. The case tests whether courts will enforce informal agreements about maintaining nonprofit missions when billions of dollars are at stake.

For OpenAI, the timing is particularly challenging as the company prepares for its IPO and faces intensifying competition. A adverse ruling could force fundamental changes to its corporate structure and leadership at a critical growth phase.

The broader AI industry is watching closely, as the precedent could influence how future AI companies balance commercial viability with stated missions to benefit humanity. The outcome may determine whether the nonprofit-to-profit transition becomes a standard playbook or a cautionary tale.
