Microsoft CEO Nadella Testifies in OpenAI Trial, Reveals AI

Microsoft CEO Satya Nadella testified in the high-stakes Musk v. Altman trial this week, revealing internal concerns about the company’s dependence on OpenAI and defending Microsoft’s $13 billion investment in the AI startup. According to CNBC, Nadella stated that Elon Musk never raised concerns to him about Microsoft’s OpenAI partnership, despite Musk naming Microsoft as a defendant in his lawsuit against OpenAI and CEO Sam Altman.

Microsoft’s OpenAI Dependency Concerns Surface

Trial testimony revealed that Microsoft harbored significant concerns about becoming too dependent on OpenAI as early as April 2022. Discovery documents showed Nadella worried about OpenAI potentially supplanting Microsoft in the technology hierarchy.

“It was becoming even more core and important that we had real agency at every layer of the stack,” Nadella testified. This concern drove Microsoft’s strategy to maintain control across its AI infrastructure while leveraging OpenAI’s capabilities.

Microsoft established itself as a major AI infrastructure provider through its early OpenAI partnership, but the company has struggled to compete directly at the model development level. The testimony suggests Microsoft sought to balance benefiting from OpenAI’s advances while maintaining strategic independence.

Edge Copilot Gets Cross-Tab Intelligence

Separately, Microsoft announced significant updates to its Edge browser’s Copilot integration. The new feature allows Copilot to gather information from all open browser tabs, enabling users to ask questions about multiple web pages simultaneously, compare products across tabs, and summarize content from various sources.

Microsoft is retiring the previous Copilot Mode, which offered more autonomous features like booking reservations. The company has folded these capabilities into the broader Copilot experience while giving users more granular control over which features they enable.

The update represents Microsoft’s continued push to integrate AI throughout its product ecosystem, making Copilot more contextually aware of user activities across different applications and services.

Board Expansion and Leadership Changes

Microsoft expanded its board of directors to 13 members with the appointment of Carmine Di Sibio, former global chairman and CEO of EY. The appointment brings expertise in financial services, risk oversight, and global client leadership to support Microsoft’s evolving AI strategy.

Di Sibio will serve on both the Compensation Committee and Audit Committee, positions that will provide oversight as Microsoft continues its substantial AI investments. His background in professional services aligns with Microsoft’s enterprise focus and cloud computing expansion.

The board expansion comes as Microsoft faces increased scrutiny over its AI partnerships and investments, particularly the OpenAI relationship that has become central to its competitive positioning.

Trial Context and Industry Implications

The ongoing trial stems from Musk’s 2024 lawsuit accusing OpenAI of abandoning its founding mission of developing AI to benefit humanity. Musk, an OpenAI cofounder, claims Altman and other leaders tricked him into funding the company before shifting focus to profit maximization.

The Verge reports that multiple key figures have testified, including OpenAI cofounder Greg Brockman, former CTO Mira Murati, and Altman himself. The trial concluded with closing arguments on May 14th.

Microsoft’s involvement as a defendant highlights how AI partnerships have become legally complex as companies navigate competitive positioning, regulatory scrutiny, and founding mission commitments.

What This Means

Microsoft’s testimony reveals the strategic tensions inherent in major AI partnerships. While the OpenAI relationship has positioned Microsoft as an AI infrastructure leader, internal documents show the company recognized risks of over-dependence on external AI capabilities.

The Edge Copilot updates demonstrate Microsoft’s approach to AI integration — embedding intelligence throughout existing products rather than creating standalone AI applications. This strategy leverages Microsoft’s existing user base while competing with Google’s AI-powered search and productivity tools.

The board appointment signals Microsoft’s commitment to governance oversight as AI investments scale. With regulatory attention increasing and partnership complexities growing, experienced financial and risk management expertise becomes crucial for navigating the evolving AI landscape.
