Elon Musk will conclude his testimony on Thursday as the trial in his lawsuit against OpenAI CEO Sam Altman rolls into its fourth day.
OpenAI’s attorney, William Savitt, cross-examined Musk for several hours on Wednesday, and the two men clashed repeatedly. Musk accused Savitt of lying and asking misleading questions that were “designed to trick” him. His cross-examination is expected to last for another hour on Thursday.
Musk sued OpenAI, Altman, and Greg Brockman, the company’s president, in 2024, alleging that they went back on their commitments to keep the artificial intelligence company a nonprofit and to follow its charitable mission. He claims that the roughly $38 million he donated to seed OpenAI, a company he co-founded, was used for unauthorized commercial purposes.
