Summary
Billionaire Elon Musk testified in a California federal jury trial on April 28, 2026, that OpenAI executives Sam Altman and Greg Brockman committed illegal conversion of the nonprofit organization into a for-profit entity. Musk's claim rests on his $38 million investment in OpenAI, which he states was conditioned explicitly on the company maintaining nonprofit status. According to Musk's testimony, the conversion by Altman and Brockman violated the charitable trust governing his donation and threatens broader implications for charitable governance nationwide.
The lawsuit frames the dispute as a matter of fundamental principle regarding charitable assets and fiduciary obligation. Musk's legal team emphasized that the case addresses whether charities can be "looted" for executive gain without legal consequence. Musk's attorney Steven Molo told the jury of nine that his client's involvement in OpenAI was foundational: "Without Elon Musk, there would be no OpenAI. Pure and simple." Molo also provided context that Musk's charitable concerns about AI governance intensified following a 2015 meeting with then-President Barack Obama, and that Musk had consistently believed artificial intelligence should not be used "as a vehicle for people to get rich."
OpenAI's legal defense directly contradicts Musk's characterization, with attorney William Savitt arguing the lawsuit is motivated by Musk's competitive interests rather than charitable principles. Savitt told the court: "We're here because Mr Musk didn't get his way at OpenAI. Because he's a competitor, Mr Musk will do anything to attack OpenAI." This framing positions the dispute as a conflict between former allies turned business rivals rather than a straightforward breach of charitable trust.
The trial has become a high-profile examination of governance structures in AI companies and the enforceability of nonprofit-to-for-profit conversions. Both parties have been warned by the judge to refrain from using their respective platforms to influence trial proceedings, a restriction underscoring the public attention surrounding the case and the reputational stakes involved for both Musk and Altman.
