GoKawiilElon Musk arrives at the federal courthouse during proceedings in the trial over his lawsuit against OpenAI in Oakland, California, on April 30, 2026.
Two days before Elon Musk's multi-billion-dollar lawsuit against OpenAI was slated to head to trial, Musk texted the company's president, Greg Brockman, to gauge his interest in a settlement, according to a filing late on Sunday.
"When Mr. Brockman responded with a suggestion that both sides drop their respective claims, Mr. Musk shot back: 'By the end of this week, you and Sam will be the most hated men in America. If you insist, so it will be,'" the filing says.
Musk, who co-founded OpenAI in 2015, sued the company, Brockman and OpenAI CEO Sam Altman in 2024, alleging they went back on their commitment to keep the artificial intelligence company a nonprofit and to follow its charitable mission.
Trial proceedings kicked off late last month in federal court in Oakland, California, and Brockman could be called to testify as soon as Monday. OpenAI's lawyers moved to enter Musk's text into evidence and suggested they plan to bring it up while Brockman is on the stand.
"It tends to prove motive and bias, and, in particular, that Mr. Musk's motivation in pursuing this lawsuit is to attack a competitor and its principals," the lawyers wrote in the filing.
