Elon Musk vs. Sam Altman: What to know as OpenAI trial opens

Jury selection has begun in Elon Musk’s fraud lawsuit against Sam Altman and OpenAI in federal court in Oakland.

Musk alleges he was misled when OpenAI shifted in 2019 from a nonprofit model to a for-profit structure.

The case could affect OpenAI’s planned 2026 IPO and may force testimony about the founders’ relationship and governance decisions.

Court filings have revived years of disputes between Musk, Altman and OpenAI over the company’s origins and direction.
