Amazon and Anthropic deepen partnership with $100B cloud commitment

Anthropic committed to spending over $100 billion on Amazon's cloud technologies over the next decade; Amazon will invest $5 billion immediately in Anthropic plus up to $20 billion more based on milestones. The deal expands Anthropic's prior relationship and provides dedicated capacity for training and inference of frontier models while strengthening Amazon's AI cloud and custom silicon offerings. This represents a major capital reallocation and compute infrastructure expansion for one of the top global AI labs.
