Microsoft CEO Satya Nadella is scheduled to testify Monday, May 11, 2026, in the legal battle between Elon Musk and OpenAI [2].
The testimony arrives at a critical juncture in the litigation, as the court examines whether OpenAI abandoned its founding principles as a nonprofit to prioritize commercial interests. Because Microsoft is the primary financial partner of OpenAI, Nadella's internal communications may provide evidence regarding the transition of the company's operational goals.
Nadella will appear in a federal courtroom in Oakland, California [3], marking the start of the third week of the trial [4]. The proceedings focus on allegations brought by Musk, who said that OpenAI betrayed its original mission to develop artificial intelligence for the benefit of humanity rather than for private profit.
A central point of contention is Microsoft’s $10 billion investment in OpenAI [1]. Musk said that this massive infusion of capital prompted the organization to shift away from its nonprofit roots and toward a closed-source, profit-driven model. The court is expected to review internal emails to determine the nature of the relationship between the two entities and how the investment influenced OpenAI's governance.
Legal representatives for OpenAI have previously defended the company's evolution, saying that the scale of modern AI development requires significant resources that a traditional nonprofit structure could not sustain. However, the introduction of Nadella as a witness suggests the court is delving deeper into the specific agreements and communications that shaped this partnership.
As the trial enters week three [4], the focus remains on the tension between open-source AI development and the corporate strategies of the world's largest technology firms. The testimony is expected to clarify the extent of Microsoft's influence over OpenAI's decision-making processes and whether that influence contradicts the organization's founding charter.

This testimony represents a pivotal moment in the trial because it moves the focus from the public disputes between Musk and Sam Altman to the private financial and strategic agreements between Microsoft and OpenAI. If the internal emails reveal that the $10 billion investment came with strings that forced a pivot away from the nonprofit mission, it could validate Musk's claims of betrayal and potentially set a legal precedent for how AI labs manage their governance and funding.
