Microsoft’s top executive Satya Nadella appeared in court Monday to provide testimony in the prominent 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 filed 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 under the premise it would remain a nonprofit organization, before transforming it into a profit-driven enterprise.
During his court appearance, Nadella recounted being abruptly removed from a November 2023 meeting to receive news that Altman had been terminated. He emphasized that no one provided him advance notice, and he never obtained a clear explanation for why the decision was made.
“There may have been some jealousy coming through,” Nadella remarked when questioned about the board’s official explanation that Altman hadn’t been consistently transparent with them.
Nadella expressed his concern at the time that OpenAI might experience a mass exodus of employees following Altman’s dismissal. Altman was quickly restored to his CEO position, an event that trial participants have dubbed “the blip.”
Allegations of Microsoft Control Challenged
Musk’s attorneys have contended that Microsoft, having pledged $13 billion to OpenAI, leveraged its financial investment to gain dominance over the organization. Nadella rejected this characterization during his courtroom testimony.
He clarified that his widely quoted statement — “We are below them, above them, around them” — referred to Microsoft’s collaborative partnership and its access to OpenAI’s technological innovations, rather than any form of control.
Nadella additionally verified that although both he and Musk possess each other’s contact information, Musk never reached out to him to express concerns regarding Microsoft’s financial commitment or its licensing agreement for GPT-3.
Court proceedings included the presentation of a group conversation between Nadella, Altman, and Kevin Scott, Microsoft’s chief technology officer. The messages revealed Nadella endorsing one of Altman’s recommended candidates for an OpenAI board position. That individual, Sue Desmond-Hellmann, was appointed to the board in 2024.
Sutskever Provides Additional Insights
Ilya Sutskever, who co-founded OpenAI, also delivered 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 telling board members that Altman exhibited a pattern of dishonesty and had worked to undermine other executives. However, he subsequently added his signature to an employee petition demanding Altman’s reinstatement, explaining that he believed the company would otherwise fail.
He further revealed that his ownership stake in OpenAI currently holds a value of roughly $7 billion. Sutskever departed from OpenAI in May 2024 to launch his own venture, Safe Superintelligence, which now carries a valuation exceeding $30 billion.
Musk’s lawsuit seeks damages totaling up to $180 billion and calls for both Altman and Brockman to be stripped of their current positions. Sam Altman is anticipated to provide testimony before the court later this week.
