According to multiple media reports, Elon Musk completed three days of testimony in his lawsuit against OpenAI on April 28-30, with cumulative testimony lasting over 7 hours. Musk, who co-founded OpenAI in 2015 with an initial investment of $38 million, claimed the company abandoned its non-profit mission to pursue commercial profit. He testified that OpenAI was established as a charitable institution serving the public and that he provided the founding concept, recruited core members, and secured all startup funding. In his lawsuit filed in California federal court, Musk seeks $130-150 billion in damages and demands OpenAI restore its non-profit status. OpenAI responded on May 1, stating Musk’s motivation stems from regret over leaving the company’s board in 2018 and jealousy over its success. The trial is expected to continue through mid-May, with key figures including CEO Sam Altman and President Greg Brockman scheduled to testify.
