Elon Musk vs. OpenAI: Trial Over the Shift from Nonprofit to For-Profit AI
4/28/2026, 12:17:36 PM
Core Lawsuit
Elon Musk sued OpenAI, CEO Sam Altman, president Greg Brockman, and Microsoft in the U.S. District Court for the Northern District of California, claiming OpenAI violated its 2015 nonprofit charter by converting to a for-profit entity. Musk seeks over $130 billion in damages, the removal of Altman and Brockman, and an order that OpenAI revert to a nonprofit. Jury selection began 27 April 2026 in Oakland; an advisory jury will hear evidence for about three weeks before Judge Yvonne Gonzalez Rogers issues a final ruling.
Origin and Structure
OpenAI was founded in May 2015 by Musk, Altman, Brockman, and Ilya Sutskever as a nonprofit research lab. Musk contributed roughly $38 million (about 60 % of early capital). After Musk left the board in 2018, the organization created a capped-profit subsidiary in March 2019 and later, in late 2025, became a public-benefit corporation. The restructuring enabled a $13 billion Microsoft investment and the 2022 launch of ChatGPT, valuing OpenAI at $852 billion.
Impact and Stakes
OpenAI’s nonprofit arm holds a 26 % equity stake plus warrants. Musk’s damages calculation multiplies the company’s valuation by the portion of that stake he attributes to his contributions (50-75 %). Claims range from $130 billion to $150 billion; Microsoft’s alleged liability is $13.3-$25 billion. A ruling could set precedent for nonprofit-to-profit conversions, affect OpenAI’s IPO, and reshape AI research governance, while also influencing Microsoft’s partnership model.
Official Statements
OpenAI described the suit as “a baseless and jealous bid to derail a competitor” and said the restructuring complied with the nonprofit charter. Microsoft denied collusion, noting its partnership began after Musk’s exit. Musk’s counsel argues OpenAI concealed its for-profit plans and misused his contributions. Judge Rogers warned both sides against “gamesmanship”.
Criticism
Legal analysts view the case as driven by personal rivalry and competitive motives. OpenAI called it a “harassment campaign” aimed at slowing its growth. Some prospective jurors expressed strong opinions about Musk, raising concerns about impartiality.
Conflicting Reports
Sources differ on damages sought ($130 billion vs. $150 billion) and OpenAI’s valuation ($852 billion vs. “?$850 billion”). Musk’s seed contribution is cited as $38 million and as 60 % of early funding. These discrepancies remain unresolved.

Next Steps
The trial should conclude by late May 2026; Judge Rogers will then decide injunctive relief, including whether OpenAI must revert to a nonprofit or pay disgorgement to its charitable arm. The outcome will likely influence OpenAI’s upcoming IPO and could prompt legislative action on AI governance.
