OpenAI leans on Amazon
OpenAI told staff it is pushing a growing alliance with Amazon after saying Microsoft had “limited our ability” to reach customers, signalling a shift in its enterprise distribution strategy. The memo frames the Amazon relationship as a way to regain channels into large buyers that often purchase through cloud and procurement partnerships. (cnbc.com)
OpenAI is telling staff that Amazon is becoming a bigger route to corporate customers as the company tries to loosen Microsoft’s grip on its sales channels. (cnbc.com) In a memo sent Sunday, chief revenue officer Denise Dresser wrote that OpenAI’s Microsoft partnership had been “foundational” but had also “limited our ability to meet enterprises where they are.” She pointed to “staggering demand” for OpenAI’s joint offering with Amazon Web Services, or AWS. (cnbc.com) The immediate product hook is Amazon Bedrock, AWS’s service for buying and managing artificial intelligence models inside Amazon’s cloud. Dresser’s memo said many large companies prefer to buy through Bedrock and existing cloud procurement contracts rather than through OpenAI directly or through Microsoft channels. (cnbc.com) That marks a change from the structure OpenAI and Microsoft laid out in January 2025, when Microsoft said exclusivity on new computing capacity would shift to a right of first refusal instead of a blanket lockup. Microsoft said at the time that OpenAI could build additional capacity elsewhere, while OpenAI’s application programming interface workloads would remain exclusive to Microsoft. (blogs.microsoft.com) Amazon has spent the past year turning that opening into a distribution business. In August 2025, AWS said OpenAI’s open-weight models were available in Amazon Bedrock and Amazon SageMaker JumpStart, giving Amazon cloud customers a way to use OpenAI systems without moving off AWS. (aws.amazon.com) The relationship expanded again on February 27, 2026, when Amazon said AWS and OpenAI would co-create a “Stateful Runtime Environment” powered by OpenAI models and sold through Bedrock. Amazon described that deal as a strategic partnership aimed at production-scale generative artificial intelligence applications and agents. (aboutamazon.com) Microsoft and OpenAI are still publicly describing each other as long-term partners. In October 2025, both companies said they had signed a new definitive agreement for the “next phase” of the partnership, with Microsoft remaining a major investor and infrastructure provider. (openai.com) The tension is over who controls the customer relationship as OpenAI’s business shifts from research labs and startups to big companies with centralized technology budgets. Those buyers often purchase software through cloud marketplaces, procurement frameworks, and existing vendor contracts that Amazon already owns. (cnbc.com) For OpenAI, the message inside the company is that Amazon is no longer just a source of chips and cloud capacity. It is becoming a storefront. (cnbc.com)
