Sam Altman and Elon Musk are facing off in a high-stakes trial that could alter the future of OpenAI and its most well-known product, ChatGPT. In 2024, Musk filed a lawsuit accusing OpenAI of abandoning its founding mission of developing AI to benefit humanity and shifting focus to boosting profits instead.

The trial began with jury selection on April 27th, before Elon Musk took the stand on Tuesday as the first witness called, portraying his interest in founding OpenAI as an effort to help save humanity, before returning to the stand on Wednesday, and again for a third day of testimony on Thursday, before his financial manager and Neuralink CEO, Jared Birchall, took the stand.

Musk was a cofounder of OpenAI and claims that Altman and cofounder Greg Brockman tricked him into giving the company money, only to turn their backs on their original goal. However, OpenAI says that “This lawsuit has always been a baseless and jealous bid to derail a competitor” in a bid to boost Musk’s own SpaceX / xAI / X companies that have launched Grok as a competitor to ChatGPT.

In his lawsuit, Musk is asking for the removal of Altman and Brockman, and for OpenAI to stop operating as a public benefit corporation. Musk has also demanded that OpenAI’s nonprofit receive up to $150 billion in damages he’s asking for if he wins the case.

On Monday, the courtroom battle between Elon Musk and Sam Altman over alleged broken promises at OpenAI started, as usual, with jury selection. The only tricky part? A lot of the prospective jurors already have an opinion about Elon Musk, and it's not a good one.

The Verge reporter Elizabeth Lopatto, who was there at the courthouse, quoted statements from some of the juror questionnaires:
