On Monday, Microsoft’s chief executive Satya Nadella appeared in court to provide testimony in the contentious legal battle initiated by Elon Musk against OpenAI and key members of its leadership team. The proceedings are taking place at the US District Court located in Oakland, California.
The lawsuit brought by Musk names OpenAI, its CEO Sam Altman, president Greg Brockman, and Microsoft as defendants. Musk alleges that Altman and Brockman deceived him into contributing tens of millions of dollars to OpenAI during its nonprofit phase, before the organization transitioned to a for-profit structure.
During his court appearance, Nadella recounted being abruptly removed from a meeting in November 2023 to receive news of Altman’s termination. He emphasized that he had received no prior notification and has never been provided with a credible explanation for the board’s action.
“There may have been some jealousy coming through,” Nadella remarked when questioned about the board’s official reasoning that Altman had failed to be consistently transparent with them.
Nadella expressed concern at the time that OpenAI would experience significant employee departures in the wake of the dismissal. Altman was quickly restored to his CEO position, an episode that trial participants have dubbed “the blip.”
Microsoft’s Role Under Scrutiny
Musk’s attorneys have contended that Microsoft, having pledged $13 billion to OpenAI, leveraged its financial muscle to exercise influence over the organization. During his testimony, Nadella contested this characterization.
He clarified that his widely-quoted statement — “We are below them, above them, around them” — referred to Microsoft’s collaborative relationship and technology access with OpenAI, rather than exercising dominance.
Nadella additionally confirmed that although both men possess each other’s contact information, Musk never reached out to him to express any apprehensions about Microsoft’s financial commitment or its licensing arrangement for GPT-3.
Court proceedings included the presentation of a group chat involving Nadella, Altman, and Kevin Scott, Microsoft’s chief technology officer. The exchange demonstrated Nadella’s endorsement of Altman’s recommendation for a new OpenAI board member. The individual in question, Sue Desmond-Hellmann, was appointed to the board in 2024.
Sutskever Testimony Adds Detail
Ilya Sutskever, who co-founded OpenAI, also provided testimony on Monday. He stated that in 2023 he informed the board that Altman’s conduct was “not conducive” to developing safe AI.
Sutskever acknowledged informing the board that Altman exhibited a pattern of dishonesty and worked to undermine other executives. However, he subsequently added his signature to a staff petition demanding Altman’s reinstatement, citing concerns that the company would otherwise fail.
He further revealed that his equity position in OpenAI currently holds a value of approximately $7 billion. Sutskever departed from OpenAI in May 2024 to establish his own venture, Safe Superintelligence, which now commands a valuation exceeding $30 billion.
Musk’s lawsuit demands up to $180 billion in damages and calls for the removal of Altman and Brockman from their positions. Sam Altman is scheduled to provide testimony later this week.
