Elon Musk vs. OpenAI: 5 Shocking Revelations from the High-Stakes Lawsuit Trial

Elon Musk’s Lawsuit Against OpenAI: Key Revelations from the Trial

Closing arguments in Elon Musk’s lawsuit against OpenAI concluded on Thursday, leaving a jury to deliberate next week. The lawsuit centers on whether Sam Altman and other executives "stole a charity" by transforming OpenAI from a nonprofit research lab into a corporate entity. Over three weeks, both sides presented evidence aiming to discredit each other and prove untrustworthiness and power hunger.

If the jury rules that Musk was misled into donating approximately $38 million to OpenAI under false pretenses, Judge Yvonne Gonzalez Rogers will determine damages, potentially reaching $150 billion. The ruling could also mandate changes to OpenAI’s leadership and governance. Even if Musk loses, state regulators may revisit the agreements that allowed OpenAI’s restructuring into a for-profit enterprise. Lawyers anticipate an appeal regardless of the outcome, prolonging the legal battle.

Five Major Revelations from the Trial

1. OpenAI’s Board Questioned Sam Altman’s Honesty

Musk’s legal team portrayed Sam Altman as untrustworthy, alleging a pattern of deception toward co-founders, employees, and board members. Multiple former employees and board members corroborated these claims in court.

"Altman’s pattern of behavior related to his honesty and candor led directly to his temporary ouster as CEO in 2023," said Helen Toner, a former board member, in a video deposition.

Mira Murati, OpenAI’s former chief technology officer, testified that Altman had a tendency to "say one thing to one person and completely the opposite to another." She also alleged that Altman lied to her about safety reviews for new AI models.

2. Greg Brockman’s Personal Diary Exposed Internal Conflicts

One of the most sensational pieces of evidence came from a personal diary kept by OpenAI president Greg Brockman. His entries revealed his internal struggle over OpenAI’s shift to a for-profit model.

• "Can’t see us turning this into a for-profit without a very nasty fight," he wrote in a 2017 entry.
• "It’d be wrong to steal the nonprofit from him," Brockman wrote, referring to Musk, who co-founded OpenAI and provided most of its startup funding.
• "He’s really not an idiot. His story will correctly be that we weren’t honest with him in the end," Brockman later wrote.
• He also candidly admitted personal ambitions: "It would be nice to be making the billions."

What’s Next for the Lawsuit?

The jury’s deliberation will determine the next steps in the case. A ruling in Musk’s favor could result in significant financial restitution and governance changes for OpenAI. Even if Musk loses, the evidence presented may prompt state regulators to reassess OpenAI’s for-profit restructuring. Legal experts suggest that the losing party will likely appeal, ensuring the dispute continues beyond the trial.
