TL;DR
OpenAI and Microsoft amended their partnership in April 2026, changing how AGI-related rights, cloud access, IP licensing and revenue sharing work between the companies. The change matters because a contractual AGI trigger had become tied to Microsoft’s investment value, OpenAI’s capital needs and customer access to models across clouds.
OpenAI and Microsoft have amended the commercial terms behind one of the technology industry’s largest AI partnerships, changing how the companies handle AGI-linked rights, cloud access, intellectual property and revenue sharing after years in which a contractual definition of artificial general intelligence sat at the center of a multibillion-dollar alliance.
The April 27, 2026 amendment, announced by OpenAI, says Microsoft remains OpenAI’s primary cloud partner, while OpenAI can now serve all its products to customers across any cloud provider. OpenAI said Microsoft’s license to OpenAI intellectual property for models and products runs through 2032 and is now non-exclusive.
The companies also changed the flow of payments. OpenAI said Microsoft will no longer pay a revenue share to OpenAI. Revenue share payments from OpenAI to Microsoft continue through 2030 at the same percentage, but are now subject to a total cap and are no longer tied to OpenAI’s technology progress, according to OpenAI’s announcement.
The change follows an October 2025 agreement in which Microsoft supported OpenAI’s formation of a public benefit corporation and recapitalization. At that time, Microsoft said it held an investment in OpenAI Group PBC valued at about $135 billion, representing roughly 27% on an as-converted diluted basis, inclusive of all owners.
Why It Matters
The amendment matters because the AGI clause was not only a philosophical marker. It affected commercial rights, model access, research IP, cloud exclusivity and revenue sharing between two companies whose products are now built into enterprise software, developer tools and consumer AI services.
For Microsoft, clearer rights through 2032 reduce uncertainty around access to OpenAI models and products. For OpenAI, the amended terms give more room to sell products across cloud providers and support the infrastructure spending needed to train and run advanced systems. For customers, the agreement could widen where OpenAI products are available, although Microsoft remains the primary cloud partner and OpenAI products are set to ship first on Azure under the stated terms.

Background
Microsoft and OpenAI began working together in 2019. The partnership grew into a core part of Microsoft’s AI strategy, while giving OpenAI access to large-scale cloud infrastructure. The earlier agreement preserved Microsoft’s exclusive IP rights and Azure API exclusivity until AGI, a term the companies treated as a contractual trigger rather than only a research milestone.
In October 2025, Microsoft said AGI declared by OpenAI would be verified by an independent expert panel. It also said Microsoft’s IP rights for models and products would extend through 2032 and include post-AGI models, with safety guardrails. Research IP rights were set to last until AGI was verified by the panel or through 2030, whichever came first.
In February 2026, Microsoft and OpenAI said the AGI definition and process had not changed. The April amendment moved the partnership toward fixed commercial dates and capped payment terms, reducing the role of an AGI determination in the economics of the deal.

What Remains Unclear
It is not clear from the public announcements how the companies will define every disputed edge case around AGI, model capability thresholds or research IP in practice. The full contract has not been made public, and neither company has disclosed the total cap on OpenAI’s revenue share payments to Microsoft.
It is also unclear how much OpenAI’s wider cloud flexibility will change customer buying behavior, infrastructure costs or Microsoft’s competitive position in AI services over time.

What’s Next
The next milestones are commercial rather than theoretical: OpenAI will need to show how broadly it sells products across cloud providers, while Microsoft will seek to keep Azure central to OpenAI workloads and retain value from its IP license, capped revenue share and equity stake through the rest of the decade.

Key Questions
What is the actual news development?
OpenAI and Microsoft amended their partnership in April 2026, changing cloud access, IP licensing and revenue sharing terms that had been linked in part to AGI-related provisions.
Did OpenAI and Microsoft remove the AGI issue entirely?
The public announcements show the companies reduced the commercial weight of an AGI trigger by setting clearer dates, caps and rights. The full private contract has not been released.
What is confirmed?
OpenAI says Microsoft remains its primary cloud partner, Microsoft’s model and product IP license runs through 2032 on a non-exclusive basis, Microsoft will stop paying revenue share to OpenAI, and OpenAI-to-Microsoft revenue share continues through 2030 with a cap.
Why does this matter to customers?
The agreement may make OpenAI products available across more cloud environments, while Azure remains the first landing place for OpenAI products under the companies’ stated terms.
What remains unclear?
The public record does not disclose the full contract, the revenue share cap, or how future AGI-related disputes would be handled if the companies disagree over technical progress.
