OpenAI is telling employees that Amazon, not Microsoft, is now the bigger channel for selling its artificial intelligence tools to large companies. (theverge.com) In a memo sent Sunday, April 12, chief revenue officer Denise Dresser wrote that demand through Amazon Web Services was “staggering” and said Amazon Bedrock had become a key route to enterprise customers. Axios and CNBC both reported that the memo cast Microsoft as a constraint on that push. (axios.com) (cnbc.com) Bedrock is Amazon Web Services’ marketplace for foundation models, which are the large systems that generate text, code, and images. OpenAI’s February 27 partnership with Amazon made Amazon Web Services the exclusive third-party cloud distribution provider for OpenAI Frontier and included a planned $50 billion Amazon investment. (openai.com) Microsoft is still a major OpenAI partner, but the relationship changed on October 28, 2025. Microsoft said then that it gave up its right of first refusal on OpenAI compute, while OpenAI committed to buy an additional $250 billion of Azure services. (blogs.microsoft.com) The memo also named Anthropic as the company OpenAI most needs to beat in enterprise sales. The Verge reported that Dresser told staff the market was “as competitive as I have ever seen it” and argued that Anthropic’s growth story was overstated. (theverge.com) That rivalry runs straight through Amazon. Anthropic said on November 22, 2024 that Amazon’s total investment would reach $8 billion and that Amazon Web Services would serve as Anthropic’s primary cloud and training partner. (anthropic.com) OpenAI’s memo lands as the biggest artificial intelligence labs are fighting over the same buyers: companies that already spend heavily on cloud software and want models inside existing contracts. CNBC reported that OpenAI is trying to reduce its reliance on Microsoft even as the two companies keep broad commercial ties in place. (cnbc.com) Amazon has said backing both labs is normal for its cloud business. Business Insider reported on April 9 that Amazon Web Services chief executive Matt Garman described the dual investments in OpenAI and Anthropic as “business as usual.” (businessinsider.com) The immediate fight is less about who trains the best model than who controls distribution. OpenAI’s own memo shows the company now sees Amazon’s cloud sales machine as the faster path into corporate accounts, even while Microsoft remains deeply embedded in its business.
