★ Must ReadAt his OpenAI trial, Musk relitigates an old friendship
Musk testified under oath in OpenAI's litigation for the first time, recounting claims about his early relationship with the company that he has previously made in interviews and Isaacson's biography. The core dispute centers on Musk's assertions about OpenAI's founding direction and his role, now being tested in a legal proceeding rather than a public narrative. This marks a significant escalation—moving his account from media statements to testimony subject to cross-examination and legal consequence. The testimony will likely become central evidence in determining OpenAI's contractual obligations and the factual record of the company's origins.
