OpenAI and Microsoft Reinforce Exclusive Partnership Terms
OpenAI and Microsoft issued a joint statement reaffirming their long‑running partnership dating to 2019 and stating that recent OpenAI funding and partner announcements do not change the existing Microsoft–OpenAI relationship. Microsoft retains its exclusive license and access to OpenAI intellectual property, and the commercial revenue‑share arrangement remains unchanged, explicitly covering revenue from OpenAI partnerships with other cloud providers. Azure is confirmed as the exclusive cloud provider for stateless OpenAI APIs and will continue to host OpenAI first‑party products (including Frontier). The contractual definition and processes for AGI remain the same. The statement also notes OpenAI’s flexibility to procure additional compute elsewhere (e.g., the Stargate project) while continuing close collaboration with Microsoft across research, engineering, and product development.
Reaffirmation of Microsoft’s exclusive IP license, Azure exclusivity for stateless OpenAI APIs, and unchanged commercial terms affect cloud infrastructure choices and commercial integrations across the AI ecosystem; important but not a disruptive policy or technical change.

OpenAI and Microsoft Amend Long-Term Partnership
OpenAI and Microsoft amended their long-term partnership on 2026-04-27 to end Microsoft’s effective exclusivity over OpenAI products and IP. Under the revised terms Microsoft retains a non-exclusive license to OpenAI model IP through 2032 and remains OpenAI’s primary cloud partner, with OpenAI products to ship first on Azure unless Microsoft opts out. Crucially, OpenAI can now sell its products to other cloud providers such as Amazon Web Services and Google. The market reacted: Microsoft shares fell about 1.4% after the announcement. Microsoft has been an early investor in OpenAI, having invested more than $13 billion; manager magazin cited an $850 billion valuation for OpenAI and estimated Microsoft’s stake at roughly $230 billion. The change follows an earlier partnership revision last autumn that altered preferred-cloud status and set interim revenue‑sharing and compute commitments.
Microsoft and OpenAI Forge New Era in Partnership
Microsoft and OpenAI have signed a new definitive agreement that recapitalizes OpenAI into a public benefit corporation (PBC) and updates the terms of their long-running partnership. After recapitalization, Microsoft will hold an investment in OpenAI Group PBC valued at approximately $135 billion, representing roughly 27% on an as-converted diluted basis. The agreement preserves Microsoft as OpenAI’s frontier model partner and extends Microsoft’s IP rights through 2032 (with research IP rights retained until either an expert panel verifies AGI or 2030). An independent expert panel will verify any AGI declaration. The deal allows OpenAI to jointly develop some products with third parties (API products exclusive to Azure; non-API products may run on any cloud), permits OpenAI to serve U.S. national security customers via API regardless of cloud, and enables OpenAI to release open-weight models that meet capability criteria. OpenAI contracted to purchase an incremental $250 billion of Azure services; Microsoft no longer has a right of first refusal to be OpenAI’s compute provider.
Microsoft and OpenAI Finalize Pricing Amendment
AI Secret’s newsletter (2026-04-28) highlights several AI industry signals: Microsoft and OpenAI finalized an amendment that removes strict cloud exclusivity, allowing OpenAI to sell through Amazon and Google Cloud while Microsoft retains primary cloud status, IP rights through 2032 and a revenue-share arrangement (the existing $250 billion Azure commitment remains). The briefing also covers non-adtech but industry-relevant items: archaeologists used AI to digitally reconstruct the face of a Pompeii eruption victim; Taylor Swift filed trademark applications for voice clips and a stage image to guard against AI deepfakes; reports on xAI’s Grok being used in Teslas and insurance pricing changes (Lemonade discounts tied to FSD miles); and a sponsored note about MyClaw, a personal-AI product powered by OpenClaw. The newsletter bundles short TL;DR items on funding, product changes, agent risks, and platform moves that affect compute, agents, and downstream enterprise adoption.
