Musk v. OpenAI: Lawsuit Over OpenAI’s Nonprofit Status
5/16/2026, 9:54:17 PM
Background: Founding and Restructuring
OpenAI launched in 2015 as a nonprofit research lab devoted to safe artificial general intelligence. Elon Musk contributed roughly $38 million and served as a co-founder until his 2018 departure. In 2019 the organization created a for-profit “capped-return” arm and accepted external capital, notably from Microsoft, which later acquired a 27 percent stake and invested over $100 billion. OpenAI maintains that the nonprofit still controls the for-profit entity, while Musk argues the shift breached the original charitable charter.
Key Players
- Elon Musk – plaintiff, seeking an injunction, removal of Sam Altman and Greg Brockman, and billions in disgorgement.
- Sam Altman – OpenAI CEO, defendant, asserts the restructuring was necessary to compete in AI.
- Greg Brockman – OpenAI president, co-founder, testified his equity is now worth $20-30 billion.
- Satya Nadella – Microsoft CEO, co-defendant, testified that Microsoft’s investment was a pragmatic partnership.
- Catherine Bracy – TechEquity CEO, activist observing the trial.
- Judge Yvonne Gonzalez Rogers – U.S. District Judge overseeing the case.
Timeline of the Legal Battle
- 2015: OpenAI founded as nonprofit.
- 2017: Musk’s last donation; internal talks about a for-profit conversion.
- 2018: Musk leaves OpenAI board.
- 2019: Creation of for-profit arm; Microsoft investment begins.
- 2024: Musk files lawsuit alleging breach of charitable trust.
- Apr-May 2026: Three-week trial in Oakland, nine-person jury selected.
- May 16 2026: Jury deliberations begin.
Financial Stakes
Musk’s contribution: $38 million. Brockman’s equity: valued at $20-30 billion. Altman’s net worth: $3.4 billion. Musk’s net worth: $814 billion. The suit seeks $150 billion in damages and the redistribution of $134 billion from OpenAI’s for-profit entity to its nonprofit arm. Microsoft’s 27 percent stake is valued at over $100 billion.
Official Statements & Responses
Musk’s counsel Steven Molo framed Altman’s credibility as central, emphasizing five witnesses who called the CEO a liar. OpenAI attorney William Savitt countered that the equity was earned through risk-taking and that Musk was aware of the for-profit plan. Judge Gonzalez Rogers repeatedly stressed that “regular people” would assess witness credibility and rejected attempts to silence the live audio feed. Catherine Bracy noted the trial’s rare demonstration of judicial equality amid billionaire litigants.
Criticism & Opposition
Witnesses, including former OpenAI CTO Mira Murati and board members Helen Toner and Tasha McCauley, described Altman’s pattern of contradictory statements. Musk’s supporters argue the restructuring diverted a charitable mission, while OpenAI’s defenders highlight the necessity of massive compute resources and the lack of any signed charitable-trust contract.
Conflicting Reports & Gaps
Sources differ on Brockman’s equity value ($20 billion vs. $30 billion) and on whether a formal charitable trust existed. The jury must also decide if the lawsuit was filed within the statute of limitations—a point Musk’s team says it was, while OpenAI contends it was not. Musk’s absence during closing arguments—traveling to China with President Donald Trump—raised questions about his commitment to the process.
Verbatim Quotes
- “I believe I’m a truthful person,” — Sam Altman, CEO of OpenAI
- “Liar’s a very powerful word in a courtroom,” Molo said.” — Steven Molo, Musk’s attorney
- “It does give you some faith in the judicial system — that it maybe is the one place left in the country that is equalizing on some level,” — Catherine Bracy, TechEquity
- “We have regular people judge the credibility of witnesses,” — Judge Yvonne Gonzalez Rogers
- “Can’t see us turning this into a for-profit without a very nasty fight,” — Greg Brockman, OpenAI President
Implications for AI Governance
The verdict could reshape how mission-driven AI labs raise capital, influence OpenAI’s planned $1 trillion IPO, and set precedent for hybrid nonprofit-for-profit structures in high-risk technologies.
What’s Next
Judge Rogers has scheduled a post-deliberation hearing to consider remedies. Both parties have signaled intent to appeal, ensuring the dispute will continue to affect the AI industry’s regulatory and investment landscape.
