The trial over OpenAI has begun, kicking off a showdown between Elon Musk and Sam Altman.
Musk was photographed entering the Oakland federal courthouse ahead of opening arguments. Sam Altman is also in the room, Business Insider’s Katherine Li confirmed.
Elon Musk is scheduled to testify as soon as today.
At the heart of the case is Musk’s accusation that Altman and other execs deceived him into donating $38 million to OpenAI based on promises that it would remain a nonprofit dedicated to developing AI for the public’s benefit, and not for private gain.
The trial pits two of the most powerful tech titans against each other. Musk is asking for up to $134 billion in damages and for Altman to lose his job, among other potential remedies.
