Elon Musk ends testimony in OpenAI lawsuit

techMay 4, 2026147

Elon Musk concluded three days of testimony Thursday in his lawsuit against OpenAI, facing cross-examination over his claim that OpenAI began as a nonprofit mission-driven lab. OpenAI's lawyers pressed him on his portrayal of the company's origins and probed his motives for suing, focusing on communications and decisions around OpenAI's move to a capped-profit structure. The testimony matters because the court's findings about whether OpenAI abandoned a nonprofit mission could influence corporate governance, investment structures, and legal limits on how AI labs convert to for-profit entities.
