Microsoft, OpenAI say partnership terms unchanged after $110B funding round
Microsoft and OpenAI confirm their long-standing AI partnership and exclusive Azure cloud provider role are unchanged after OpenAI's recent $110 billion funding round.
Jersey City, N.J., March 4, 2026
Microsoft and OpenAI on February 27th said their long-standing AI partnership remains unchanged following OpenAI’s $110 billion funding round, reaffirming Microsoft’s exclusive intellectual property rights and Azure’s role as the cloud provider for OpenAI’s core services.
The statement follows OpenAI’s announcement that it raised $110 billion at a $730 billion valuation, including $50 billion from Amazon, $30 billion from Nvidia, and $30 billion from SoftBank, according to OpenAI’s Feb. 27 post. The company also disclosed a strategic partnership with Amazon to expand cloud infrastructure capacity.
In response, Microsoft and OpenAI said the new investments do not alter the structure of their commercial agreement. The joint statement confirms that Microsoft “maintains its exclusive license and access to intellectual property across OpenAI models and products.” It also states that the companies’ revenue-sharing arrangement “remains unchanged,” including revenue generated through OpenAI’s partnerships with other cloud providers.
On infrastructure, the companies reiterated that Microsoft Azure will remain the exclusive cloud provider for OpenAI’s stateless AI services. According to the statement, any stateless API calls, including those tied to other commercial partnerships, will be hosted on Azure. OpenAI’s first-party products, including ChatGPT and enterprise platforms, will also continue to run on Azure infrastructure.
Microsoft said agreements with additional cloud providers were anticipated under its existing partnership terms. The statement notes that collaborations such as the OpenAI-Amazon arrangement were “always contemplated under our agreements.”
The clarification addresses market questions about whether OpenAI’s expanded investor base would dilute Microsoft’s position. VentureBeat reported that the structure ensures Microsoft remains positioned as a primary commercial beneficiary of OpenAI’s model deployment, even as the startup broadens infrastructure relationships.
For enterprise customers, the announcement reduces uncertainty. Azure remains the gateway for accessing OpenAI’s core AI capabilities within Microsoft products and services. That continuity is significant for U.S. enterprises integrating generative AI into cloud, productivity and data platforms.
The companies said they remain committed to advancing AI responsibly and continuing their collaboration.
Why this matters
For B2B companies building on OpenAI models, the clarification reinforces Azure’s position as the primary enterprise gateway. Despite new investors and cloud partnerships, Microsoft retains exclusive licensing access and continues to host stateless API services.
That continuity reduces platform risk for SaaS vendors embedding generative AI into enterprise workflows. For companies aligning product roadmaps and cloud strategy, the message is straightforward: OpenAI’s capital expansion does not change the commercial backbone underpinning its enterprise deployment.
