Musk is suing OpenAI, CEO Sam Altman, president Greg Brockman, and Microsoft. He claims Altman and Brockman misled him into donating tens of millions of dollars to OpenAI when it was a nonprofit, only to later convert it into a for-profit company.
Nadella told the court he was pulled out of a meeting in November 2023 to be informed that Altman had been fired. He said he was not warned in advance and was never given a satisfactory reason for the decision.
“There may have been some jealousy coming through,” Nadella said when asked about the board’s stated reason that Altman had not been consistently candid with them.
Nadella said he was worried at the time that OpenAI employees would leave the company in large numbers following the firing. Altman was reinstated as CEO shortly after, in what has been referred to in the trial as “the blip.”
Microsoft’s Role Under Scrutiny
Musk’s legal team has argued that Microsoft, which has committed $13 billion to OpenAI, used its financial position to exert control over the company. Nadella pushed back on that framing during his testimony.
He said his now-famous comment — “We are below them, above them, around them” — was about Microsoft’s strategic partnership and access to OpenAI’s technology, not about control.
Nadella also confirmed that despite the two men having each other’s phone numbers, Musk never contacted him to raise concerns about Microsoft’s investment or its license for GPT-3.
A group chat between Nadella, Altman, and Microsoft’s chief technology officer Kevin Scott was shown in court. It showed Nadella approving one of Altman’s suggested candidates for a new OpenAI board seat. That person, Sue Desmond-Hellmann, joined the board in 2024.
Sutskever Testimony Adds Detail
OpenAI co-founder Ilya Sutskever also took the stand on Monday. He testified that he told the board in 2023 that Altman’s behavior was “not conducive” to building safe AI.
Sutskever confirmed that he told the board Altman had a pattern of lying and undermining executives. But he later signed a staff petition calling for Altman’s return, saying he feared the company would otherwise collapse.
He also disclosed that his stake in OpenAI is currently worth around $7 billion. Sutskever left OpenAI in May 2024 to start his own company, Safe Superintelligence, now valued at over $30 billion.
Musk is seeking up to $180 billion in damages and wants Altman and Brockman removed from their roles. Sam Altman is expected to testify later this week.
