Anthropic launched Claude Platform on AWS on Sunday, two weeks after OpenAI put GPT-5.5 and GPT-5.4 on Amazon Bedrock. AWS now hosts both frontier model families on a single bill with IAM authentication, CloudTrail logging, and consumption-based pricing. Claude Platform goes further than Bedrock: managed agents, code execution, web search, and day-one access to new features through Anthropic’s native APIs. The setup takes about ten minutes. I tested it.
Anthropic is responding to a specific threat. OpenAI ended its Azure exclusivity on April 28 and immediately landed on Bedrock, where Anthropic currently holds roughly 38% of token consumption. Claude is now the only frontier model on all three major clouds; OpenAI is on two. Anthropic hit $30 billion ARR in April, passing OpenAI’s $25 billion while spending roughly four times less on training. Amazon has invested more than $13 billion in Anthropic with commitments for $20 billion more. The revenue and distribution numbers favor Anthropic today, but those Bedrock share numbers will compress fast now that GPT-5.5 is on the same platform.
Near-zero switching costs between frontier models on the same bill sounds like a buyer’s market. It is, for now. When you can swap Claude for GPT-5.5 with a one-line code change, models start looking interchangeable, and the platform hosting them all owns the customer relationship and the pricing power. We’ve seen this before in cable TV, app stores, and cloud computing itself; the distributor always wins. Every A/B test you run teaches AWS more about pricing your next contract than it teaches you about model quality.
Every company needs a Claw strategy. Do you have one?
