Microsoft CEO Satya Nadella testified Monday, May 11, 2026 [1], in a federal court in Oakland, California, regarding the control of OpenAI [3].
The testimony arrives at a critical juncture in the legal battle between Elon Musk and Sam Altman. The outcome could redefine the governance of artificial intelligence, and the legality of corporate partnerships with non-profit entities.
Nadella's appearance occurred during the third week of the trial [2]. The proceedings center on allegations from Musk that Microsoft's investment in OpenAI violated specific terms established during the company's inception. Musk said the partnership shifted OpenAI away from its original mission of benefiting humanity through open-source development.
During the testimony, Nadella addressed the nature of the partnership between Microsoft and OpenAI [4]. The legal challenge focuses on whether the corporate relationship effectively transformed the non-profit organization into a commercial arm of Microsoft. This dispute highlights the tension between the rapid scaling of AI technology and the original governance structures intended to keep such power decentralized.
Court records indicate that the testimony was aimed at clarifying how Microsoft's financial contributions and infrastructure support influenced OpenAI's operational decisions [4]. The trial has become a focal point for the tech industry, as it examines the boundaries of influence that a major investor can exert over a partner that claims a non-profit status.
As the trial enters its third week [2], the court continues to evaluate the specific contractual obligations and the intent behind the initial agreements. The testimony from Microsoft's leadership is intended to provide a defense against the claim that the partnership was a breach of trust, or a violation of the organization's founding charter [4].
“Satya Nadella testified on Monday, May 11, 2026”
This testimony represents a pivotal moment in the trial because it puts the primary benefactor of OpenAI's commercial success under oath. If the court finds that Microsoft's influence over OpenAI violated its original non-profit mandate, it could set a legal precedent that restricts how venture capital and big tech firms structure partnerships with research-driven AI labs.
