OpenAI Signs $838B in Infrastructure Deals Away from Microsoft Azure

OpenAI has announced over $838 billion in infrastructure commitments with providers other than Microsoft Azure, fundamentally reshaping the AI partnership landscape.

The Deals

Partner Value Purpose
AWS $38B EC2 UltraServers, 100K+ GPUs
Oracle $300B 5-year training workloads
Stargate $500B Dedicated US datacenters

What Microsoft Retains

  • $250B Azure commitment (unchanged)
  • 27% equity stake in OpenAI
  • IP rights and revenue share through 2030

The Shift

Microsoft’s relative share of OpenAI’s compute is declining even as the absolute commitment remains substantial. OpenAI CEO Sam Altman: “Scaling frontier AI requires massive, reliable compute.”

Microsoft’s Response

The company has pivoted from “exclusive OpenAI partner” to “platform for all AI” — signing deals with Anthropic, Nebius, and others to diversify its AI customer base.
