Musk v. Altman et al

Case Summary

Elon Musk’s complaint alleges that Sam Altman, Gregory Brockman, and a network of OpenAI-related entities fraudulently induced him to help found and fund OpenAI as a nonprofit devoted to developing safe AI and broadly sharing research and technology, then later shifted to a profit-driven structure that allegedly locked down OpenAI’s most valuable technology, concentrated benefits with Microsoft and affiliated for-profit entities, and enabled self-dealing and unjust enrichment.
