Elon Musk vs. OpenAI: Trial Over Alleged Breach of Charitable Trust and Unjust Enrichment
5/14/2026, 10:51:34 PM
The Lawsuit and Core Claims
Elon Musk, a co-founder of OpenAI, filed a civil suit in 2024 alleging that OpenAI’s leadership—CEO Sam Altman, president Greg Brockman, and the nonprofit’s board—breached a charitable trust and engaged in unjust enrichment. The complaint asserts that the organization shifted from its original nonprofit mission to a for-profit structure, enriching its executives while sidelining Musk’s $38 million early investment.
Origins of the Dispute
OpenAI was founded in 2015 as a nonprofit dedicated to safe, open-source AI. By 2023 the company created a for-profit subsidiary to attract large-scale funding, a move Musk opposed. He left the board in 2018 after disagreements over control of artificial general intelligence (AGI). The lawsuit seeks to revert OpenAI to its nonprofit form and remove Altman and Brockman from leadership.

Trial Timeline and Procedural Milestones
- 2024: Musk files lawsuit.

- May 13 2026: Closing arguments begin.
- Late May 2026: Jury deliberations expected; judge may issue advisory decision.
Financial Stakes and Legal Demands
Musk seeks removal of Altman and Brockman, unwinding of OpenAI’s for-profit arm, and disgorgement of up to $150 billion to the nonprofit entity. Earlier filings referenced a $134 billion redistribution request. OpenAI’s for-profit subsidiary is valued in the “hundreds of billions” while the nonprofit remains the legal owner.
Official Statements & Judicial Responses
Musk’s counsel argued that Altman’s credibility is central, citing five witnesses who labeled him a liar. The judge rebuked Molo for asserting Musk was not seeking monetary relief, ordering clarification that billions of dollars are indeed being claimed. Altman’s attorneys contend that Molo’s references to a Senate investigation were inaccurate; the inquiry originated from a House committee.
Criticism, Opposition, and Counterclaims
Altman’s legal team accused Molo of presenting “unsubstantiated allegations” and “unfounded hearsay,” particularly regarding the alleged Senate letter and alleged false statements in SEC filings. Witnesses for the defense, including Murati and Toner, described patterns of dishonesty and chaotic leadership by Altman. Microsoft’s Nadella characterized the board’s 2023 attempt to remove Altman as “amateur city” and expressed concern over employee morale.
Conflicting Reports and Evidentiary Gaps
- Molo claimed a Senate investigation, while records show only a House request for information.
- Musk’s attorney asserted the lawsuit seeks no money; the judge confirmed a claim for billions in disgorgement.
- The existence of a formal charitable-trust contract remains disputed; parties rely on emails, website content, and press statements as evidence.
Verbatim Quotes
- “ Advertising “I confronted Sam Altman with the fact that five witnesses in this trial, all people that he’s known for years and worked with, called him a liar under oath.” — Steven Molo, attorney for Elon Musk
- “Mr. Musk did try to kill it,” — Sam Altman, CEO of OpenAI
- “I'm sure there are some times in my life when I did not.” — Sam Altman, responding to truthfulness question
- “It was sort of amateur city as far as I’m concerned,” — Satya Nadella, CEO of Microsoft
- “By the end of this week, you and Sam will be the most hated men in America. If you insist, so it will be,” — Elon Musk, text to Greg Brockman
Potential Implications for the AI Industry
A ruling favoring Musk could force OpenAI to revert to a nonprofit model, potentially delaying its planned IPO and altering its capital structure. Conversely, a verdict for OpenAI would preserve its for-profit subsidiary, maintaining its current trajectory in AI development and market positioning.
Next Steps
The jury is slated to begin deliberations next week, with Judge Rogers expected to issue an advisory decision shortly thereafter. The outcome will determine OpenAI’s governance, financial obligations, and broader competitive dynamics in the artificial-intelligence sector.
