Key Points

  • Microsoft to hold 27% stake in OpenAI Group PBC, valued near $135B.

  • OpenAI’s nonprofit arm keeps a $130B interest in the new for-profit entity.

  • Microsoft loses exclusive cloud rights, but OpenAI will buy $250B in Azure services.

  • Both firms can now pursue AGI independently, under new usage limits and oversight.

Microsoft and OpenAI Redefine Their AI Partnership

Microsoft and OpenAI have formalized a new for-profit structure, giving Microsoft a 27% ownership stake and clearing the path for OpenAI’s transformation into a public benefit corporation.

The deal reshapes one of the most influential relationships in the AI world — granting both companies more flexibility while keeping their collaboration intact.

Deal Highlights

Ownership & Rights

  • Microsoft gains a 27% equity position valued around $135 billion.
  • The OpenAI nonprofit retains oversight with a $130 billion stake.
  • Microsoft keeps access to OpenAI’s models and IP through 2032, excluding consumer hardware.

Cloud & Infrastructure

  • Microsoft no longer holds exclusive Azure rights, but OpenAI has agreed to spend $250 billion on Azure services.
  • OpenAI may now partner with other cloud vendors for non-API products.

AGI Clauses

  • Microsoft’s research rights end in 2030 or once AGI is confirmed, whichever comes first.
  • An independent expert panel will verify any AGI breakthrough.
  • Microsoft can pursue its own AGI work but faces compute limits if using OpenAI tech.

What It Means for AI’s Future

The move allows OpenAI to expand independently, including its “Stargate Project” of large-scale U.S. data centers.
For Microsoft, it locks in long-term access to leading AI technology while reducing regulatory scrutiny.

Both firms now occupy the center of global AI infrastructure, rivaling Amazon, Google, and Anthropic.

WSA Take

This new structure signals a mature, strategic phase for AI partnerships.
OpenAI gains autonomy; Microsoft retains power — and the balance between the two may shape the next decade of artificial intelligence.
