Musk vs Altman Trial Begins as $134B OpenAI Lawsuit Goes to Jury

Elon Musk’s high-stakes lawsuit against OpenAI and CEO Sam Altman began jury selection on April 27th, with Musk seeking up to $134 billion in damages and demanding the removal of Altman and president Greg Brockman from their leadership roles. According to MIT Technology Review, the case could determine whether OpenAI is allowed to continue operating as a for-profit enterprise ahead of its highly anticipated IPO.

Musk, who co-founded OpenAI with Altman in 2015 before leaving in 2018, alleges that Altman and Brockman deceived him into funding the company by promising to maintain it as a nonprofit dedicated to developing AI that benefits humanity. 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.”

Core Legal Claims and Financial Stakes

Musk’s lawsuit centers on allegations that OpenAI abandoned its founding nonprofit mission after he invested tens of millions of dollars in the company’s early development. According to court filings, Musk is seeking $134 billion in damages from OpenAI and Microsoft, one of the company’s biggest financial backers.

The lawsuit asks the court to restore OpenAI as a nonprofit organization and remove both Altman and Brockman from their executive positions. Notably, Musk has requested that any damages be awarded to OpenAI’s nonprofit arm rather than to him personally, according to additional court documents.

OpenAI has dismissed the case as baseless. 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 including xAI and its Grok chatbot.

Key Witnesses and Expected Testimony

Nine jurors will deliver an advisory verdict to guide the judge’s final decision on Musk’s claims. MIT Technology Review confirmed that Musk, Altman, and Brockman will all take the stand during the proceedings.

High-profile witnesses expected to testify include former OpenAI chief scientist Ilya Sutskever, former CTO Mira Murati, and Microsoft CEO Satya Nadella. The trial is expected to reveal internal communications, diary entries, and behind-the-scenes details about OpenAI’s founding and transformation from nonprofit to for-profit structure.

Musk has been actively promoting negative coverage 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” in reference to his nickname for the OpenAI leader.

OpenAI’s Corporate Transformation Timeline

OpenAI launched in 2015 as a nonprofit research organization with Musk as a co-founder and major early investor. The company promised to develop artificial general intelligence that would benefit all of humanity rather than concentrate power in the hands of a few corporations.

However, OpenAI began shifting toward a for-profit model in 2019, eventually restructuring to operate a for-profit subsidiary. This transformation accelerated after the success of ChatGPT and subsequent partnerships with Microsoft, which has invested billions in the company.

Musk departed OpenAI in 2018 following what sources described as a “bitter power struggle” over the company’s direction. He later launched his own AI company, xAI, which developed the Grok chatbot as a competitor to ChatGPT.

Broader AI Industry Implications

The trial comes at a critical juncture for the AI industry, with OpenAI preparing for what could be one of the largest tech IPOs in history. A ruling against OpenAI could force the company to restructure its operations and potentially delay or complicate its public offering plans.

The case also highlights broader tensions in the AI industry over corporate governance, profit motives, and the development of artificial general intelligence. Musk has consistently argued that AI development should prioritize safety and broad societal benefit over commercial interests.

Meanwhile, speculation continues about OpenAI’s next major product release. Recent reports suggest Altman has referred to a potential “ChatGPT 5.5” as a significant milestone toward artificial general intelligence, though the company has not officially confirmed these plans.

What This Means

This trial represents more than a personal dispute between two tech billionaires — it could fundamentally reshape how AI companies balance profit motives with stated missions to benefit humanity. A ruling in Musk’s favor would set a precedent that nonprofit commitments carry legal weight even as companies evolve their business models.

For OpenAI, the stakes couldn’t be higher. Beyond the massive financial exposure, the company faces the possibility of leadership changes and structural reorganization that could disrupt its competitive position against rivals like Google’s Gemini and Anthropic’s Claude.

The trial also serves as a stress test for the AI industry’s governance models. As companies race to develop increasingly powerful AI systems, questions about accountability, transparency, and mission alignment will likely face increased scrutiny from regulators and the public.
