Elon Musk's lawsuit against OpenAI began on April 27th in the U.S. District Court in Oakland, California, with jury selection commenced. Opening statements are expected to begin on Tuesday. Prior to the trial, the two sides escalated their public exchanges on the X platform, with OpenAI claiming the lawsuit is baseless, while Musk repeatedly attacked Sam Altman, calling him "Scam Altman." The core of the case revolves around the controversy surrounding OpenAI's for-profit transformation. Musk accuses OpenAI of violating its founding non-profit commitment and is seeking up to $134 billion in damages, while also demanding the reversal of the for-profit transformation and the removal of relevant executives. The liability determination phase is expected to continue until mid-May.
