Key facts
- Announced 2026-04-27 (per secondary coverage)
- AGI clause removed; replaced by a date - 2032 - rather than an AGI determination trigger
- Exclusivity ended; OpenAI products still ship on Microsoft platforms first
- Microsoft remains OpenAI’s primary cloud provider
- Five weeks later Microsoft launched seven first-party MAI models at Build (2026-06-02)
What happened
Microsoft and OpenAI announced a restructured agreement. According to coverage, the long-controversial AGI clause - under which an OpenAI declaration of AGI could cut off Microsoft’s IP rights and revenue share - was removed and replaced by a fixed 2032 horizon, and exclusivity ended. Microsoft stays OpenAI’s primary cloud partner.
Why it matters
It removed the single largest legal uncertainty in the AI industry’s most important partnership and turned it into a conventional commercial relationship, while Microsoft simultaneously built its own frontier model stack (MAI).
Confidence is medium: this entry is based on secondary coverage; the primary Microsoft/OpenAI announcement was not read directly.
