OpenAI sells ChatGPT Enterprise through AWS Marketplace

ChatGPT Enterprise is now listed on AWS Marketplace. Enterprises can procure it using their existing AWS agreements, which typically means the spend counts against committed cloud budgets and lands on a single AWS invoice rather than requiring a new vendor contract.

Procurement friction is a real barrier in large companies. Many have pre-negotiated AWS commitments they must spend down, and Marketplace listings let business units adopt software without a fresh legal and security review cycle. For OpenAI, that opens doors in AWS-centric organizations that might otherwise default to Microsoft Copilot or to Anthropic's Claude on Bedrock.

The move continues OpenAI's broadening beyond Microsoft. Earlier this year it made models available on AWS, and this week Bedrock carried OpenAI GPT-5.5 and Codex alongside Anthropic's freshly launched Fable 5.2. AWS itself reported Fortune 500 Bedrock spend up nearly 7X year over year. Greg Brockman posted that "integrating with OpenAI can drive a lot of business."

The listing also sits awkwardly with Microsoft's position as OpenAI's largest partner, which is simultaneously pushing consumption-based Copilot billing. Watch whether Azure responds with pricing incentives, and whether Google Cloud gets a similar listing.
