Microsoft and OpenAI have modified their partnership terms as OpenAI joins a $500 billion data center initiative with Oracle and SoftBank Group.
The big picture: The “Stargate” joint venture aims to construct AI data centers across the United States, representing a significant shift in OpenAI’s infrastructure strategy beyond its exclusive Microsoft partnership.
- President Trump announced the initiative at the White House, positioning it as a strategic move to maintain U.S. technological leadership over China
- The project will utilize Nvidia chips for AI computing capabilities
- The venture includes additional investors such as UAE-based MGX
Key structural details: OpenAI will maintain significant control within the new joint venture while preserving core elements of its Microsoft partnership.
- The venture is structured as a separate entity with OpenAI holding equity stake and operational control
- SoftBank CEO Masayoshi Son will serve as board chairman
- A dedicated board appointed by founding members will oversee operations, with its own CEO
Microsoft’s evolving role: While loosening some restrictions, Microsoft maintains critical aspects of its OpenAI partnership through 2030.
- Microsoft has approved OpenAI’s ability to build additional infrastructure, primarily for research and model training
- The company retains exclusive rights to offer OpenAI’s API services to developers and business customers
- Bilateral revenue sharing agreements between Microsoft and OpenAI remain in place
- OpenAI has committed to a new, large-scale usage of Microsoft’s Azure cloud services
Strategic partnerships: The initiative brings together multiple technology leaders while maintaining certain boundaries.
- Microsoft, Nvidia, and Arm will serve as technology partners without equity investment
- Oracle’s role appears limited as Microsoft maintains exclusive control over OpenAI’s API services
- The involvement of international investors like UAE’s MGX signals global interest in U.S. AI infrastructure
Looking ahead: This restructuring of relationships between major AI players could reshape the competitive landscape of AI infrastructure development, though Microsoft’s continued central role in OpenAI’s commercial operations suggests a carefully balanced approach to expansion rather than a dramatic shift in allegiances.
