Anthropic has committed to spending $100 billion on AWS over ten years.
In exchange, Amazon is investing up to $33 billion into Anthropic.
That is not a vendor relationship. That is a structural alliance between two of the most consequential organizations in AI.
The scale: 1 million+ Trainium2 chips. Project Rainier at $11 billion and 2.2 GW. Up to 5 GW of total compute secured from AWS. Claude is the most popular model family on Amazon Bedrock, used by 100,000 organizations.
And yet Anthropic is simultaneously building its own $50 billion data centers with Fluidstack in Texas and New York, maintaining a tri-cloud posture across AWS, Google Cloud, and Azure, and reportedly securing up to $40 billion and 5 GW from Google over five years.
The strategy is clear: deepest possible integration with AWS while deliberately avoiding dependency on any single provider.
At this scale, infrastructure is not just a cost center. It is the competitive moat.
