A trial in the lawsuit brought by Elon Musk against OpenAI CEO Samuel Altman and other defendants—including tech giant Microsoft—is scheduled to begin April 27, according to a federal court order issued Tuesday, Jan. 13. The legal showdown will center on Musk's claim that OpenAI and Altman abandoned the startup's original nonprofit, public-benefit mission and misled him while turning the lab into a highly lucrative, Microsoft-linked for-profit enterprise. OpenAI went on to release ChatGPT in 2022 and Musk eventually launched a rival, xAI. Microsoft, a major investor in OpenAI since 2019, has poured billions into the firm and become its biggest shareholder after a restructuring last year. The trial, to be held before a jury, will be presided over by US District Judge Yvonne Gonzalez Rogers in Oakland, California.
