Nadella’s Courtroom Disclosures Put $100B Microsoft–OpenAI Bet Under the Microscope
Testifying in the Musk v. Altman trial on 12-13 May 2026, Satya Nadella revealed Microsoft has poured over $100 billion into OpenAI and renegotiated the once-exclusive deal into a non-exclusive, 27 % equity stake arrangement that ties OpenAI to buy $250 billion of Azure compute while freeing both sides to build rival frontier models.
Focusing Facts
- Microsoft’s equity outlay of roughly $13 billion since 2019 now converts into a 26.79 % stake valued at $228 billion after OpenAI’s February–March 2026 $122 billion raise at an $852 billion valuation.
- Bloomberg testimony showed total Microsoft spend—including infrastructure build-outs—exceeds $100 billion, and OpenAI is contractually committed to $250 billion in Azure purchases with revenue-share payments capped at $38 billion through 2030.
- An April 2022 internal email revealed Nadella’s fear of becoming “IBM to OpenAI’s Microsoft,” echoing IBM’s 1980 DOS licensing misstep.
