Elon Musk, the world’s wealthiest individual, took the stand for a second day in a landmark trial, accusing fellow OpenAI co-founder Sam Altman of betraying promises to keep the AI company a nonprofit dedicated to humanity’s benefit.
The trial scrutinizes the 2015 birth of the ChatGPT maker, initially a nonprofit startup primarily funded by Musk, before its transformation into a capitalistic venture now valued at $852 billion.
Musk, who invested approximately $38 million in OpenAI from December 2015 through May 2017, testified about the company’s early years. He recounted losing confidence that Mr. Altman would uphold its nonprofit status, stating under questioning from his lawyer Steven Molo that by late 2022 he was concerned Mr. Altman was trying to “steal the charity.”
Dressed in his usual black suit and tie, Musk declared on the witness stand, “It turned out to be true.”
Altman, OpenAI’s CEO, was in attendance at the federal courthouse in Oakland, California, although he was not scheduled to testify on Wednesday. The trial started Monday and is expected to last about four weeks.
Lawyers for OpenAI have rejected the allegations brought in Musk’s civil lawsuit and said there were never promises that the company would remain a nonprofit forever. The company has argued Musk’s legal challenge is aimed at undercutting OpenAI’s rapid growth and bolstering Musk’s xAI, which he launched in 2023 as a competitor.
During cross-examination, Musk repeatedly pushed back on questions. OpenAI lawyer William Savitt was asking about emails Musk wrote before OpenAI’s founding in 2015 on whether it would be better to make it a standard for-profit company and about tax deductions from his donations to the nonprofit.
“Your questions are not simple,” Musk said. “They are designed to trick me essentially.” Any simple answer, he said, would be misleading the jury.
Judge Yvonne Gonzalez Rogers stepped in, asking Musk to answer whether it’s true or false that OpenAI was formed as a nonprofit in December 2015. Musk said in that case, the answer was yes, but added that it is not always simple, comparing it to asking “have you stopped beating your wife?”
“We are not going to go there,” the judge replied, to laughs in the courtroom.
Despite moments of levity, the stakes are high at the trial, which could sway the balance of power in artificial intelligence. Musk’s lawsuit seeks Altman’s ouster from OpenAI’s board. If Musk wins, it could derail OpenAI’s plans for an initial public offering of its shares.
Musk’s decision to stop funding the company contributed to a bitter falling out between the former allies that’s been evident throughout the trial. On Wednesday, Musk said his views on Altman and his OpenAI cofounders had three phases — from initial excitement to losing confidence to a period in late 2022 when he thought “wait a second, these guys are betraying their promise.”
Lawyers for OpenAI have said Musk sought to control the company for himself.
Musk repeatedly testified that while he initially sought a majority stake in OpenAI and control of four out of seven board seats, this would eventually be diluted when OpenAI grew and gained more shareholders. He compared it to his stake in Tesla, which he said is now around 15 percent after he initially had a majority stake when the electric car maker was founded over two decades ago.
OpenAI, however, claims there were no assurances that he would eventually relinquish his board majority.
