Singapore – Microsoft and OpenAI have confirmed that their longstanding collaboration remains unchanged following OpenAI’s latest funding announcements and the introduction of new strategic partners.
The two organisations, which began working together in 2019, agreed that the structure of their alliance continues as previously outlined, including arrangements disclosed in their joint communication in October 2025. They indicated that recent developments do not alter the legal or commercial foundations of their relationship.
Both companies continue to cooperate across research, engineering and product development, building on several years of technical integration. The intellectual property framework also remains intact, with Microsoft retaining exclusive licensing rights and access to OpenAI’s models and associated technologies.
The commercial agreement between the parties, including revenue-sharing provisions, is unchanged. Existing terms have always accounted for OpenAI entering into partnerships with other cloud providers. Recent collaborations, including OpenAI’s work with Amazon, were described as being consistent with the current contractual framework.
Microsoft’s Azure platform continues as the sole cloud provider for stateless application programming interfaces, offering access to OpenAI models and intellectual property. Such services may be procured either through Microsoft or directly from OpenAI, with Azure providing the underlying global infrastructure and enterprise capabilities. Any stateless API usage arising from OpenAI’s collaborations with third parties, including Amazon, is to be hosted on Azure.
OpenAI’s proprietary products, including Frontier, will also continue to operate on Azure infrastructure. The contractual definition of artificial general intelligence and the mechanisms for determining its achievement remain unchanged.
The companies mentioned that the partnership allows OpenAI to expand its computing capacity through additional large-scale infrastructure initiatives, such as the Stargate project, while maintaining the core terms of the collaboration.
The structure of the partnership between Microsoft and OpenAI was designed to enable independent commercial activity alongside continued joint development, and confirmed their ongoing commitment to advancing artificial intelligence technologies within the existing framework of their agreement.
