Microsoft adjusts OpenAI deal after $500 billion Stargate AI venture
The US conglomerate retains key rights amid the new shift.

Microsoft announced changes to its longstanding agreement with OpenAI following the AI leader’s new partnership with Oracle and SoftBank on a $500 billion AI data centre project, Stargate. The joint venture, unveiled by President Donald Trump at the White House, aims to solidify US leadership in AI, leveraging Nvidia chips and other cutting-edge technologies.
While Microsoft retains exclusive rights to OpenAI’s APIs, the amendments now allow OpenAI to build additional capacity outside of Microsoft’s infrastructure. This paves the way for Oracle’s involvement in Stargate, which will operate as a separate entity with governance rights shared among founding members and external investors like UAE’s MGX. SoftBank CEO Masayoshi Son will chair the venture’s board.
Despite this shift, Microsoft remains a central technology partner, continuing to benefit from revenue-sharing agreements with OpenAI and maintaining exclusivity over key offerings through its Azure cloud service. “The key elements of our partnership remain intact through 2030,” Microsoft said, reaffirming its commitment to OpenAI’s long-term growth.
Oracle and OpenAI have not commented on Microsoft’s statements, but the partnership underscores the strategic realignments shaping the future of AI infrastructure in the US.
