Two of the most powerful figures in artificial intelligence, Elon Musk and Sam Altman, are now facing off in a federal courtroom in San Francisco. The jury trial, which began April 27, 2026, centers on Musk's claim that OpenAI betrayed its founding promise to develop AI for the public good.
Musk alleges he donated roughly $44 million to OpenAI as a nonprofit. He claims the organization then transformed into a profit-driven machine, partnered with Microsoft, and abandoned its original mission. The fraud and unjust enrichment claims survived pretrial dismissals and are now before a jury. Musk testified from April 28 to 30.
OpenAI’s defense argues there was no binding contract locking the organization into nonprofit status forever. They also point to Musk’s own for-profit AI company, xAI, suggesting his motives are competitive, not charitable.
The case raises a critical question for the industry: can a nonprofit that accepted donations based on a public-benefit mission later restructure into a for-profit entity once its technology becomes extremely valuable?
A verdict against OpenAI could set a precedent, exposing similar organizations to legal risk if they pivot to commercial models. It may also trigger regulatory scrutiny of Microsoft’s partnership with OpenAI.
