# Microsoft and OpenAI restructure partnership, drop the AGI clause and exclusivity

In late April 2026 Microsoft and OpenAI overhauled their partnership, reportedly removing the contractual "AGI clause" (replaced by a fixed 2032 date) and ending exclusivity, while Microsoft remains OpenAI's primary cloud partner. The change freed Microsoft to push its own first-party MAI models.

## 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.
