Microsoft CEO Satya Nadella is set to take the stand this Monday in Oakland, California, as a key witness in Elon Musk’s lawsuit against OpenAI. The testimony is expected to center on internal emails that detail Microsoft’s role in funding OpenAI’s transition from a philanthropic non-profit to a multi-billion-dollar for-profit entity.
Nadella’s appearance marks a pivotal moment in the trial, which has exposed the intense rivalries and internal conflicts among Silicon Valley’s elite. His testimony will be followed by OpenAI CEO Sam Altman, who is expected to testify later this week.
The Core of the Dispute
Elon Musk, a co-founder of OpenAI, alleges that the organization betrayed its founding mission to develop artificial intelligence for the benefit of humanity. Key points of the lawsuit include:
-
Misuse of Funds: Musk claims his $38 million in founding donations were misappropriated to build a commercial empire now valued at over $850 billion.
-
Mission Drift: The Tesla CEO is seeking a court order to force OpenAI back into its original non-profit status—a move that could significantly disrupt its competitive standing against rivals like Google and Anthropic.
-
OpenAI’s Defense: The company maintains that Musk left voluntarily after a failed attempt to seize majority control and is now acting as a direct competitor through his own firm, xAI.
The “Paper Trail” of Profit
On Monday, Musk’s legal team will use recently disclosed Microsoft emails from 2018 to argue that Microsoft only invested once it saw a path to profit. In these emails, Nadella expressed skepticism about OpenAI’s research until Musk began publicly touting the startup’s potential for breakthroughs in Artificial General Intelligence (AGI).
Following these discussions, OpenAI established a for-profit subsidiary in 2019, securing an initial $1 billion from Microsoft. That investment has since grown to $13 billion, with Microsoft’s stake now valued at a staggering $228 billion.
Trial Drama and Future Implications
The trial has already featured explosive testimony. Last week, OpenAI co-founder Greg Brockman faced questioning over 2017 diary entries that appeared to prioritize personal wealth. Brockman, in turn, alleged that Musk physically threatened him during a power struggle that same year.
The stakes for the AI industry are immense:
-
Verdict Timeline: An “advisory” jury is expected to reach a verdict by the week of May 18.
-
Potential Ruling: If Judge Yvonne Gonzalez Rogers rules against OpenAI, it could jeopardize the company’s planned initial public offering (IPO).
-
Shifting Alliances: Adding another layer to the rivalry, Musk recently announced a major partnership between his company, SpaceX, and OpenAI’s primary competitor, Anthropic.
