Trial Spotlight: Nadella’s Testimony on Microsoft’s Role in OpenAI’s Evolution
On May 11, 2026, Satya Nadella, chief executive of Microsoft, took the stand in the federal courtroom in Oakland, California. He answered questions about Microsoft’s partnership with OpenAI, the timing of its investments, and whether the collaboration compromised OpenAI’s original nonprofit charter. Nadella asserted that OpenAI “had all the rights and resources they always had” and that the company retained independence even as Microsoft deepened its partnership.
From Nonprofit Roots to For-Profit Partnerships
OpenAI was founded in 2015 as a nonprofit research lab. Elon Musk, a co-founder, contributed $38 million in donations that were intended to support charitable AI research. In 2019, Microsoft invested $1 billion in a newly created for-profit arm of OpenAI, followed by $2 billion in 2021 and $10 billion in 2023. The funding enabled OpenAI to commercialize its models, most notably ChatGPT, launched in late 2022. Musk alleges that these investments shifted OpenAI away from its nonprofit mission, prompting his 2024 lawsuit that now includes Microsoft as a defendant.
Key Players
- Elon Musk – Founder of Tesla, SpaceX, and xAI; plaintiff alleging breach of nonprofit duty.
- Satya Nadella – Microsoft CEO, witness defending Microsoft’s role.
- Sam Altman – OpenAI CEO, scheduled to testify later in the week.
- Greg Brockman – OpenAI president and co-founder, also a plaintiff.
- Ilya Sutskever – OpenAI co-founder, testified earlier in the trial.
- Judge Yvonne Gonzalez Rogers – Presiding federal judge.
Financial Trail: Microsoft’s $13 Billion Investment
Microsoft’s capital commitments to OpenAI total $13 billion: $1 billion (2019), $2 billion (2021), and $10 billion (2023). The partnership granted Microsoft a share of future profits and an exclusive one-year license to commercialize a flagship model. Internal 2018 emails reveal that Microsoft executives initially deemed OpenAI “no value in engaging” and questioned the research’s relevance, yet later reversed course to avoid losing the lab to Amazon.
Official Statements & Responses
- Microsoft: Claims it was unaware of any conditions attached to Musk’s earlier donations and maintains that OpenAI “retained its independence” throughout the partnership.
- OpenAI: States that the nonprofit foundation still controls the organization and that the for-profit arm is essential for scaling safe AI.
- Musk: Argues that OpenAI “misused” his $38 million donation, violated its charter, and that Microsoft “aided and abetted” the shift to a for-profit structure.
Criticism & Opposition
Musk’s legal team cites the 2018 internal emails as evidence that Microsoft knowingly supported a transition contrary to OpenAI’s mission. Musk also posted in September 2020 that OpenAI was “essentially captured by Microsoft.” Conversely, Microsoft executives highlighted concerns that rejecting OpenAI could have driven the lab to Amazon, suggesting a strategic rather than malicious motive.
On-the-Ground Courtroom Dynamics
Nadella entered the Oakland courthouse in a navy suit, answered questions for roughly an hour, and emphasized that his remarks about “being below them, above them, around them” referred to reassuring Microsoft customers, not exerting control. The trial’s evidence phase is slated to conclude on Wednesday, with closing arguments expected Thursday.
Conflicting Reports & Gaps
- Investment Impact: Musk describes the $10 billion 2023 infusion as the “tipping point,” while Microsoft frames it as a standard commercial partnership.
- Internal Sentiment: Early emails label OpenAI’s work as low-value, yet later statements assert full rights and resources for the lab.
- Valuation Figures: One source cites Microsoft’s stake valued at $228 billion, a figure not corroborated elsewhere in the record.

What’s Next
Closing arguments are expected later this week, and the nine-member advisory jury will begin deliberations the week of May 18. The judge will issue any final remedies after the jury’s liability recommendation. The outcome could reshape OpenAI’s corporate structure and influence future collaborations between large tech firms and AI research entities.
