Key Takeaways
- Chief Revenue Officer Denise Dresser distributed an internal communication highlighting Amazon’s partnership as crucial for enterprise expansion
- The memo stated Microsoft’s partnership “limited our ability to meet enterprises where they are”
- Amazon revealed intentions to commit up to $50 billion to OpenAI in late February 2026
- Enterprise clients now represent 40% of OpenAI’s total revenue, projected to equal consumer revenue by year’s end
- Dresser challenged Anthropic’s approach, describing it as founded on “fear, restriction, and the idea that a small group of elites should control AI”
In an internal communication distributed to employees on Sunday, OpenAI’s Chief Revenue Officer Denise Dresser celebrated the company’s emerging partnership with Amazon while acknowledging that its existing Microsoft collaboration has created constraints.
The communication, obtained by CNBC, was sent approximately six weeks following Amazon’s announcement of a potential $50 billion investment in OpenAI through a strategic alliance.
“Our Microsoft partnership has been foundational to our success. But it has also limited our ability to meet enterprises where they are — for many that’s Bedrock,” Dresser stated.
Amazon Web Services’ Bedrock infrastructure enables organizations to access leading AI models, including those from OpenAI, via a unified cloud platform. According to OpenAI, interest following the Amazon announcement has been “frankly staggering.”
Microsoft has poured over $13 billion into OpenAI beginning in 2019. While both entities describe their relationship as fundamental and strategic, they’ve increasingly entered competitive territory. Microsoft explicitly listed OpenAI among its competitors in its 2024 annual filing.
OpenAI has begun collaborating with additional cloud infrastructure providers such as CoreWeave, Google, and Oracle to expand its computational capacity.
Enterprise Market Competition Intensifies
OpenAI is aggressively pursuing the enterprise sector, where Anthropic’s Claude platform has established significant market presence. Google Gemini is similarly vying for dominance in this segment.
Dresser informed CNBC earlier this month that enterprise clients currently contribute 40% of OpenAI’s overall revenue. She indicated expectations for this segment to match consumer revenue by year-end.
During last week’s HumanX AI conference in San Francisco, Glean CEO Arvind Jain characterized enthusiasm for Anthropic’s Claude as “Claude mania,” stating “it has become a religion.”
OpenAI Challenges Anthropic’s Approach
Dresser leveraged the memo to directly challenge Anthropic, characterizing its methodology as rooted in “fear, restriction, and the idea that a small group of elites should control AI.”
She further asserted that Anthropic committed a “strategic misstep to not acquire enough compute.” A separate OpenAI communication to investors on Thursday indicated Anthropic is “operating on a meaningfully smaller curve.”
Anthropic disclosed a computational infrastructure agreement with Google and Broadcom for “multiple gigawatts” earlier this month.
OpenAI achieved a valuation exceeding $850 billion during a late March funding round. Anthropic reached a $380 billion valuation one month prior. Both organizations are considering potential public offerings this year.
Dresser joined as chief revenue officer in December. Her background includes serving as CEO of Slack and holding executive positions at Salesforce.
She concluded the communication by telling employees: “The market is ours to win, let’s execute accordingly.”
