Microsoft Corporation (NASDAQ: MSFT) and OpenAI announced on Monday April 27 that they have fundamentally restructured the commercial relationship that has defined the AI industry since 2019, ending Microsoft’s exclusive access to OpenAI’s technology and allowing ChatGPT and other OpenAI products to be hosted on competing cloud platforms including Amazon Web Services and Google Cloud for the first time.
Sam Altman confirmed the change on X, writing: “We have updated our partnership with Microsoft. Microsoft will remain our primary cloud partner, but we are now able to make our products and services available across all clouds. Will continue to provide them with models and products until 2032, and a revenue share through 2030.”
The restructuring resolves a tension that had been building for months since OpenAI signed a $50 billion cloud agreement with Amazon in February, a deal that Microsoft had reportedly considered challenging legally on the grounds that it infringed on exclusivity provisions in the original partnership agreement, with the Financial Times having reported Microsoft was exploring a potential lawsuit against both companies.
That threat is now eliminated. By agreeing to drop the exclusivity requirement, Microsoft removes the legal overhang while walking away with a set of commercial terms that arguably favour its own long-term interest: the company will no longer be required to pay a revenue share to OpenAI for Azure resales, while receiving a non-exclusive licence to OpenAI’s intellectual property through 2032 and remaining OpenAI’s designated primary cloud provider.
OpenAI’s revenue share payments to Microsoft, which have historically been calculated at a 20 percent rate on ChatGPT subscription and product sales, will continue through 2030 but are now subject to a total cap, the specific dollar value of which has not been publicly disclosed, though TechCrunch noted that last quarter alone Microsoft reported $7.5 billion in revenue from its OpenAI investment, providing a reference point for the scale of the financial flows between the two companies.
The AGI trigger clause, which had previously required Microsoft to determine its response if OpenAI achieved artificial general intelligence before the partnership’s obligations were settled, has been removed entirely, replacing an ambiguous conceptual threshold with concrete dates and capped financial commitments that both companies can plan around with certainty.
Denise Dresser, OpenAI’s chief revenue officer, had circulated an internal memo earlier in April describing the original partnership terms as having “limited our ability to meet enterprises where they are,” a direct acknowledgement that the exclusivity arrangement was functionally suppressing OpenAI’s commercial reach by preventing enterprise customers who had committed to AWS or Google Cloud from accessing OpenAI products through their existing cloud relationships.
Amazon Web Services CEO Andy Jassy posted on X immediately after the announcement: “Very interesting announcement from OpenAI this morning. We’re excited to make OpenAI’s models available directly to customers on Bedrock in the coming weeks,” signalling that AWS integration of ChatGPT and related OpenAI products will materialise rapidly rather than requiring extended technical preparation.
Barclays analysts characterised the restructuring as beneficial for both companies, noting that it allows Microsoft to reduce infrastructure burden while enabling OpenAI to scale faster across platforms, a framing that describes the deal as a negotiated mutual benefit rather than a concession by either party, though the practical removal of exclusivity is widely understood as a concession by Microsoft that reflects changing market realities.
MSFT shares rose fractionally on Monday following the announcement, a muted reaction that suggests markets are treating the restructuring as broadly neutral to slightly positive for the stock heading into Tuesday’s Q3 2026 earnings report, where the OpenAI backlog question that has weighed on investor sentiment since February is now expected to be addressed with a clarity that the new agreement’s defined timelines and capped payments make possible for the first time.
