OpenAI Ends Exclusive Microsoft Cloud Deal, Expands Partnership with AWS

OpenAI recently announced a major restructuring of its partnership with Microsoft, formally ending the multi-year exclusive cloud service agreement. Under the new terms, OpenAI is no longer tied solely to Microsoft Azure and can now offer its cutting-edge models directly through Amazon Web Services (AWS) and Google Cloud. At the same time, Microsoft has dropped its revenue-sharing obligation with OpenAI, instead retaining all revenue generated by selling OpenAI models on Azure. This structural change is seen as a pivotal moment in OpenAI’s journey toward multi-cloud independence.

Following the new agreement, OpenAI quickly deepened its partnership with Amazon Web Services (AWS). In an official blog post, AWS confirmed that both parties will integrate the latest model capabilities into the Amazon Bedrock platform and launch an intelligent agent building tool, Codex, powered by OpenAI’s frontier models. Amazon had already announced a $50 billion investment in OpenAI back in February, with OpenAI committing to use 2 GW of AWS’s self-developed Trainium chips for model training. OpenAI’s revenue chief, Denise Dresser, stressed that the AWS collaboration is “not directly related” to the Microsoft restructuring. However, analysts note that the two moves—just a day apart—clearly signal a shift toward a multi-cloud ecosystem.

Meanwhile, Google Cloud is closely reviewing the new contract terms. According to sources, the company is evaluating the possibility of partnering with OpenAI. With Microsoft no longer holding exclusive rights, OpenAI can now significantly broaden its enterprise customer reach through multiple platforms. This change marks a trade-off where OpenAI exchanges steady revenue for strategic autonomy—and signals that competition in the cloud AI services market will only intensify.

Commentary: OpenAI’s “divorce” from Microsoft is essentially a battle for control over cloud infrastructure. By breaking free from a single vendor lock-in, OpenAI can deploy its models across more scenarios while simultaneously pushing Microsoft, Amazon, and Google into more aggressive price and technology competition in AI services. For enterprise users, multi-cloud deployment flexibility will become a key factor when choosing AI platforms moving forward.
