Musk v. Altman live updates: Trial enters 2nd week with focus shifting to OpenAI president

The legal battle between Elon Musk and OpenAI CEO Sam Altman is entering its second week Monday at a federal courthouse in Oakland, with testimony expected from one of the defendants after Musk spent much of the first week on the witness stand.

Musk, the world's richest man, is suing his OpenAI co-founders, claiming they are "stealing a charity." He has maintained that characterization throughout the proceedings.

After Musk's extended testimony during week one, the trial is set to shift focus as co-defendant and OpenAI President Greg Brockman takes the stand to begin week two. Brockman's journal entries, which were unsealed earlier this year as legal teams prepared for trial, are expected to be part of the testimony.

Vincent Joralemon, director of the Berkeley Center for Law & Technology and a former corporate attorney who has been following the case, said the disclosure highlights how invasive the legal process has been.

"A lot of the listeners here may not realize that, how intrusive this is," Joralemon said. "You know, Greg Brockman kept a journal and had to turn that over as evidence."

Joralemon said Musk's legal team is expected to continue emphasizing the idea that OpenAI's founders never truly intended the organization to remain a nonprofit.

"I think you're going to see a lot of Musk's side try to paint this as you never really thought this was going to be a nonprofit," he said.

Musk's testimony dominated most of the first week of trial and included several heated exchanges in the courtroom. According to Joralemon, the opening phase of the proceedings may have gone better for Musk than anticipated.

"Week one, actually probably went better for Elon than I would have expected," he said.

Beyond the courtroom, Joralemon said the case is also playing out in public opinion and could have broader market implications. OpenAI is set to go public later this year, and Joralemon suggested Musk has a financial incentive to introduce uncertainty.

"There is a real big economic benefit for him to create as much uncertainty around OpenAI as possible," he said.

Last week, the judge rejected multiple arguments from Musk's legal team, including Musk's repeated references to the "Terminator." Musk has said several times in court that artificial intelligence could kill humanity.

"This is the one circumstance, where Elon cannot just say whatever he wants," Joralemon said.

Musk has described the lawsuit as a case involving a stolen charity, while the defendants argue he is suing because he does not control OpenAI. Regardless of the case's outcome, Joralemon said the dispute itself could still benefit Musk.

"If Elon is, you know, putting, kind of giving OpenAI a black eye and starting to make them look, like they are unscrupulous or making them start to kind of look like the bad guys that might pay off in the long run for them," he said.

Elon Musk on Thursday sparred with an attorney for OpenAI during his third day of testimony in the contentious trial over the company's pivot from nonprofit status to a for-profit venture valued at hundreds of billions of dollars.

The trial centers on the 2015 birth of the ChatGPT maker as a nonprofit startup primarily funded by Musk. It pits the world's richest person against Sam Altman, a fellow OpenAI co-founder he accuses of betraying promises to keep the company as a nonprofit dedicated to humanity's benefit.

Tempers have flared on both sides of the high-stakes trial, as the morning began with an existential discussion about the future of humanity - complete with references to "The Terminator" movies - and how much witness testimony would focus on AI safety.

"Your client, despite these risks, is creating a company that is in the exact same space," Judge Yvonne Gonzalez Rogers told Musk's lawyers, referring to the billionaire's xAI, which launched in 2023. People, she said, "don't want to put the future of humanity into Mr. Musk's hands," and instructed the parties not to discuss the dangers of AI to humanity during the course of the trial.

"This is not a trial on the safety risks of artificial intelligence. This is not a trial on whether or not AI has damaged humanity," she said. "It could be one day in a federal court in this country that we may have that trial. That is not this trial and we are not going to get sidetracked on that issue in this trial."

On the stand, Musk has taken issue with the cross-examination by opposing attorney William Savitt, accusing him of asking misleading questions designed to trick him and the jury. At one point Thursday, Savitt asked Musk about earlier testimony where he said that as long as investor profits were capped, OpenAI wasn't in violation of agreements to keep it a nonprofit.

"It depends on how high the cap is," Musk replied. Savitt then said that "wasn't your complete answer yesterday right?" In response, Musk said "few answers are going to be complete, especially if you cut me off all the time." He added that if the cap is "super high," then OpenAI is "really a for-profit at that point."

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.

The trial in federal court in Oakland, California, is scheduled to continue through late May. Judge Yvonne Gonzalez Rogers excused Musk from the witness stand Thursday, but he may be called back later.

During the cross-examination, Savitt also asked Musk about his companies - Tesla, SpaceX, Neuralink and X - and whether they were all for-profit. Musk replied yes, and affirmed that he believes all of these companies are "socially beneficial."

Savitt then asked why Musk hasn't started a nonprofit himself, eight years after he left OpenAI.

"I thought I had started a nonprofit with OpenAI but they stole it," Musk replied, adding that this is "the entire basis of this lawsuit."

Elon Musk clashed with a defense attorney Wednesday during cross-examination in his federal trial over OpenAI's origins, with repeated courtroom tension, judicial intervention and disputes over early company emails and structure.

Musk, who was being questioned for a second day on the witness stand, pushed back against questions from defense attorney William Savitt, arguing at times that they were misleading.

At one point, Musk told Savitt his questions were "not a simple yes or no" and were "designed to trick me," prompting continued back-and-forth between the two. He also said some of the e-mails and messages he was asked about in court were difficult to recall as they were many years ago.

The exchanges escalated enough for Judge Yvonne Gonzalez Rogers to intervene several times, instructing both sides to stop speaking over one another so the jurors could hear what they were saying and also so the court reporter could transcribe.

Savitt, who previously represented Twitter in its legal battle with Musk over his $44 billion takeover of the company, is now part of the defense team representing OpenAI.

The case centers on Musk's claim that OpenAI deviated from its founding mission as a nonprofit created to benefit humanity. Musk helped found the company in 2015 and invested roughly $38 million.

He alleges the organization shifted away from its original charitable purpose as it moved toward a more commercial structure. Musk has argued the company should have remained under nonprofit control and has accused OpenAI leadership of straying from its founding commitments.

Defense attorneys, however, have pointed to emails, text messages and deposition testimony they say show Musk was aware of and at times supported discussions about alternative corporate structures, including arrangements involving for-profit entities supporting nonprofit work.

In court, Savitt presented several pieces of evidence he argued showed Musk's early proposals envisioned him holding significant control.

Musk argued that control would have decreased as the company brought in additional investors and board members

The defense has argued the dispute is ultimately about control and competition in the artificial intelligence industry, alleging Musk became critical of OpenAI only after losing influence and later launching his own AI company, xAI. Savitt questioned Musk on his reasonings for cutting off quarterly funding in 2017, wondering if it was to force "financial pressure" on a company he felt he couldn't gain
control of.

Savitt said the evidence "is not as how Mr. Musk has described them," referencing what he characterized as a broader documentary record of early discussions and agreements.

Musk has maintained he was never opposed to a for-profit structure so long as profits are capped and the organization continues to serve its original nonprofit mission. He has also accused OpenAI leadership of abandoning that mission and has described himself as having been misled.

The defense, meanwhile, has portrayed Musk as a founder who became dissatisfied after failing to secure control and later withdrew financial support as tensions escalated.

Musk is expected to return to the stand Wednesday to complete cross-examination. Two additional witnesses are expected to follow and then next up: defendant and OpenAI Greg Brockman.

Elon Musk took the stand for a second day of testimony against OpenAI and its leaders in a lawsuit that could reshape the future of artificial intelligence, as the emerging technology has sent ripples through the economy and financial markets.

Musk claims OpenAI betrayed its initial nonprofit mission when it changed its corporate structure; OpenAI, for its part, claims Musk's suit is meant to derail its position as a competitor to his own artificial intelligence company, xAI.

In court, email exchanges between Musk and Altman were shown.

On one e-mail exchange between the two about the non-profit structure, Musk reflects: "I was foolish enough to believe him.'

Musk said he received reassurances that OpenAI would remain non-profit and continued to donate over what he estimates was $10 million.
