A federal courtroom in Oakland became the venue last week for one of the stranger legal showdowns in tech history: Elon Musk versus Sam Altman, the man running the company Musk helped create.
Musk is suing OpenAI, which he co-founded and funded starting in 2015, arguing that the millions he donated came with a condition - OpenAI would remain a nonprofit developing AI for humanity, not a company built to generate returns for investors. His core claim is that OpenAI's pivot toward a for-profit structure violated that founding agreement. MIT Technology Review reported from inside the courtroom that both men were present in person, a rare occasion for two people whose public feud has mostly played out through press releases and social media posts.
The legal dispute centers on OpenAI's 2019 restructuring, when it created a "capped profit" subsidiary to attract outside investment. Since then, the company has raised tens of billions of dollars and sits at a valuation above $300 billion. ChatGPT, its flagship product, has over 400 million weekly active users. That commercial trajectory is precisely what Musk argues the founders agreed to prevent.
The conflict of interest is obvious: Musk's own AI company, xAI, competes directly with OpenAI. His critics frame this entire lawsuit as a business dispute wrapped in the language of mission and ethics. His attorneys argue the founding documents are straightforward.
What Hangs on the Verdict
The stakes extend well past these two men. OpenAI is currently mid-transition, trying to convert from its nonprofit structure into a standard for-profit company that gives investors conventional equity. A ruling in Musk's favor - or even a damaging settlement - could block or complicate that conversion. A loss for Musk likely clears the path entirely and lets OpenAI complete the restructuring on its own timeline.
The trial is expected to run several more weeks.
