Microsoft’s Exclusive Tie with OpenAI Ends: What the New Partnership Means

Updated Microsoft‑OpenAI partnership

Microsoft remains OpenAI’s primary cloud partner, but the intellectual‑property licence for OpenAI models and products changes from exclusive to non‑exclusive, effective through 2032.

Background

In October 2023 OpenAI and Microsoft signed an agreement that gave Microsoft roughly 27 % of OpenAI after a recapitalisation that valued the company at about $135 billion.

The announcement caused Microsoft’s share price to open down ~1 % and fall as much as 4 % in pre‑market trading.

Key terms of the refreshed agreement

Microsoft stays the main cloud partner; OpenAI products will be prioritized on Azure unless Microsoft cannot support a capability, and OpenAI may now sell on other clouds.

The IP licence for OpenAI models and products remains in force until 2032 but is no longer exclusive.

Microsoft will no longer pay a revenue‑share to OpenAI.

OpenAI’s revenue‑share to Microsoft continues until 2030, with the same percentage and a total‑cap, and is not tied to technical progress.

Microsoft remains a significant shareholder and will continue to be directly involved in OpenAI’s growth.

Public statements

Sam Altman: “We have updated our partnership with Microsoft. Microsoft remains our primary cloud partner, but we can now offer our products on all cloud platforms. We will continue to provide models to Microsoft through 2032 and keep the revenue‑share arrangement until 2030.”

Andy Jassy: “We look forward to bringing OpenAI models directly into Bedrock for customers and supporting the upcoming Stateful Runtime Environment, giving developers more flexibility in model selection.”

Strategic context

Since 2019 Microsoft has invested about $1 billion, becoming a strategic partner as OpenAI moved to a capped‑profit model. GPT‑3 was trained on Azure and Microsoft built dedicated AI super‑computing infrastructure. In 2023 Microsoft deepened the tie by prioritising GPT‑4 on Azure, integrating AI into Bing, launching Copilot for Microsoft 365, and opening the Azure OpenAI Service to developers. Competition in generative AI in 2024 prompted both parties to adjust the relationship, resulting in the current less‑exclusive arrangement.

Analysts note that the new agreement removes references to AGI, which some interpret as a sign that OpenAI may define its AGI strategy ahead of a potential IPO.
