Microsoft CEO and OpenAI Co-founder who both helped oust Sam Altman take the stand

Testimony from Microsoft CEO Satya Nadella and OpenAI co-founder Ilya Sutskever highlighted competing narratives Monday in the legal battle between Elon Musk and OpenAI, as jurors heard from key witnesses in federal court.
Musk is suing Microsoft for aiding and abetting in a breach of charitable trust, as part of a broader case centered on OpenAI's structure and mission. Nadella took the stand early Monday morning, having been seen pacing in the hallways before his testimony.
"From the OpenAI perspective, the testimony of Mr. Nadella was compelling, candid, straightforward and told the story, which is that Microsoft was a partner," said William Savitt, an attorney for OpenAI.
Nadella described Microsoft's early investment in OpenAI as a significant risk and framed the relationship as a partnership that helped the company grow. He testified that Musk never raised concerns directly with him, saying, "We have each other's phone numbers."
The Microsoft CEO also addressed the brief removal and reinstatement of OpenAI CEO Sam Altman in 2023, a pivotal moment referenced frequently during the trial.
"After Sam Altman was fired and reinstated Nadella, Nadella was in close communication with Mr. Altman and with others at OpenAI, and it was instrumental in his reinstatement and in choosing a new board for the nonprofit," said Marc Toberoff, an attorney for Musk.
Nadella denied demanding Altman's reinstatement, instead characterizing Microsoft's role as an effort to stabilize OpenAI.
He testified that the company sought clarity from the board while also preparing contingency plans to hire Altman and other OpenAI staff if necessary.
Jurors also heard from Ilya Sutskever, OpenAI's co-founder and former chief scientist, who offered insight into the company's early days and internal dynamics.
Sutskever testified that Musk pushed him outside his comfort zone but said there was never a promise that OpenAI would remain a nonprofit organization.
"What you heard him say is that there were never any promises made that could form the charitable trust that Mr. Musk says existed," Savitt said.
Sutskever also addressed his role in Altman's temporary ouster, describing it as an urgent move driven by concerns about leadership.
"I simply care," said Sutskever on the witness stand. "I didn't want it to be destroyed," as he explained his decision and concerns that Altman's behavior was not conducive to maintaining a safe environment for artificial intelligence development.
He testified that he had concerns about Altman's leadership for about a year before the decision and described the situation as a "Hail Mary."
Sutskever's testimony also underscored his long-standing belief in OpenAI's mission. He said he once declined a $6 million annual salary at Google to join OpenAI and estimated his current stake in the company at about $7 billion.
The case has drawn a sharp contrast between Musk's argument, summarized in court as "It's not OK to steal a charity," and Sutskever's one-liner today: "The mission of OpenAI is larger than the structure." With testimony from Nadella and Sutskever complete, jurors are now hearing from Bret Taylor, chairman of the board of directors, as well as chairman of the OpenAI Foundation, which is the non-profit governing the for-profit subsidiary.
Up next: Sam Altman, who is anticipated to take the stand as early as Tuesday.
The trial is progressing toward closing arguments, with jurors expected to begin deliberations by Thursday.
