The Anthropic-AWS Axis
Amazon's Anthropic bet is paying off — $9.5B in paper gains and deepening technical integration. This is reshaping cloud AI strategy.
Amazon mentioned Anthropic three times in its earnings press release — as an investment ($9.5B unrealized gains), as a compute customer (Project Rainier's 500K Trainium2 chips dedicated to Claude), and as a Bedrock integration (Claude Sonnet, Opus, and Haiku).
Meanwhile, Microsoft's OpenAI investment is getting more expensive — $3.1B in losses this quarter, up from $523M a year ago. The contrast is stark: Amazon is profiting from Anthropic while deepening integration. Microsoft is subsidizing OpenAI while the losses accelerate.
The strategic implication: AWS is becoming the "model-neutral" cloud with the deepest Anthropic integration. It hosts Anthropic, OpenAI, and DeepSeek on Bedrock. Azure is OpenAI-first. Google trains Gemini in-house. Your cloud choice now implies an AI model strategy — and that choice is getting stickier every quarter.
