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
