Musk v. Altman trial nears end with key testimony on OpenAI's shift from nonprofit to for-profit.

The high-profile trial between Elon Musk and OpenAI CEO Sam Altman is concluding its second week, focusing on Musk's lawsuit alleging OpenAI broke promises to remain a nonprofit. Shivon Zilis, a former OpenAI board member and Musk's partner, testified about intense debates over OpenAI's corporate structure, including for-profit options. Musk claims the for-profit arm became dominant against original intentions, while Zilis detailed discussions and Musk's offer to integrate OpenAI with Tesla. The trial may call more executives, including Altman and Microsoft CEO Satya Nadella, as it progresses.
