Elon Musk vs. Sam Altman: Trial Over OpenAI's For-Profit Shift Begins

ai-technology · 2026-04-17

Elon Musk and OpenAI CEO Sam Altman go to trial this week in Northern California over OpenAI's restructuring from a nonprofit to a for-profit entity. Musk, who co-founded OpenAI in 2015 and left in 2018, alleges Altman and president Greg Brockman deceived him into bankrolling the company with promises it would remain a nonprofit dedicated to benefiting humanity. He seeks up to $134 billion in damages from OpenAI and Microsoft, and asks the court to remove Altman and Brockman and restore OpenAI as a nonprofit. Nine jurors will deliver an advisory verdict; Musk, Altman, Brockman, former chief scientist Ilya Sutskever, former CTO Mira Murati, and Microsoft CEO Satya Nadella are expected to testify. The trial could impact OpenAI's planned IPO, valued at over $850 billion, and give Musk's rival xAI (valued at $1.25 trillion with SpaceX) an advantage. State attorneys general of California and Delaware have already approved OpenAI's new structure with conditions, but legal experts question Musk's standing and the applicable law.
