Musk Testifies Again in OpenAI Lawsuit Amid Trust Issues and $10B Investment

AI Summary

Elon Musk is testifying for the third time in his lawsuit against OpenAI and its CEO Sam Altman. Musk claims he lost trust in Altman in late 2022, coinciding with Microsoft's $10 billion investment in OpenAI. He alleges that his $38 million donation for OpenAI's nonprofit mission has been misused for commercial purposes. The trial, overseen by Judge Yvonne Gonzalez Rogers, is expected to include testimonies from other witnesses, including Musk's family office manager Jared Birchall.
