Satya Nadella Testifies in Musk vs. OpenAI Trial, Defending $13B Investment
Satya Nadella testimony OpenAI trial 2026
Microsoft CEO Satya Nadella took the witness stand in an Oakland federal court on Monday, May 11, 2026, to provide critical testimony in the ongoing legal battle between Elon Musk and OpenAI. During more than two hours of questioning, Nadella vigorously defended Microsoft’s $13 billion cumulative investment in the artificial intelligence startup. He dismissed allegations from the Tesla CEO that the partnership was a conspiratorial effort to transform a charitable nonprofit into a profit-driven corporate entity.
Nadella testified that Microsoft performed extensive due diligence before its initial 2019 investment and found no evidence of conditions attached to Musk’s founding donations. The tech leader also noted that Musk never personally contacted him to express concerns about the partnership, despite the two maintaining a direct line of communication.
The testimony offered a rare glimpse into the strategic motivations behind one of the most significant corporate alliances in history. Nadella admitted to jurors that the investment was driven by a fear that Microsoft could become “the next IBM” if it failed to secure a leading position in the burgeoning artificial intelligence sector. Internal emails presented during the trial revealed that Microsoft leadership viewed the partnership as a survival bet, with 2023 memos projecting a staggering $92 billion return on the investment by the end of the decade.
Nadella characterized the relationship as a transparent, commercially motivated agreement where Microsoft provided essential Azure cloud computing resources in exchange for exclusive licensing rights. He argued that Microsoft took substantial financial risks when others were hesitant to back the “fledgling lab,” justifying the company’s current significant stake in the for-profit subsidiary.
Addressing the dramatic November 2023 leadership crisis at OpenAI, Nadella described the board’s sudden firing of CEO Sam Altman as “amateur city.” He testified that he was blindsided by the decision and found the board’s public explanation about Altman’s lack of candor to be entirely insufficient given the depth of Microsoft’s partnership.
While Nadella clarified that he did not explicitly demand Altman’s reinstatement, his testimony highlighted the chaotic governance that Musk’s legal team claims is evidence of a betrayal of the organization’s founding mission. As the trial moves toward closing arguments on Thursday, the jury’s assessment of Nadella’s testimony will be pivotal in determining whether OpenAI’s restructuring violated its nonprofit commitments or was a necessary evolution for technological advancement.
