Amazon expanded its partnership with AI startup Anthropic today.

Amazon will invest up to an additional $25 billion into the company.

This investment builds on a previous $8 billion commitment.

Anthropic pledged to spend over $100 billion on Amazon Web Services (AWS) cloud technology over the next decade.

AWS becomes the primary provider for training Anthropic’s Claude AI models.

Anthropic secured up to 5 gigawatts of computing capacity for model training.

The startup will use Amazon’s custom Trainium processors for current and future AI development.

The deal secures a major customer for Amazon’s custom silicon infrastructure.

Over 100,000 existing AWS customers currently use Anthropic’s models.
