Amazon commits up to $25 billion to AI startup Anthropic, securing $100 billion in guaranteed cloud spending over 10 years

Amazon announced a two-part investment deal with Anthropic: $5 billion upfront plus up to $20 billion tied to hitting commercial milestones. In return, Anthropic committed to spending more than $100 billion on Amazon Web Services (AWS) over the next decade and reserving up to 5 gigawatts of computing power to train and run its Claude AI models.

This locks in a major long-term customer for AWS, Amazon's cloud division, which grew revenue 24% year-over-year to $35.6 billion in Q4 2025. The deal specifically ensures Anthropic will use Amazon's custom-built Trainium chips (the processors that run AI models on AWS), converting Amazon's hardware investments into guaranteed revenue rather than speculation.

For your work: if you use Claude (Anthropic's AI assistant) at your company, this means Claude's performance and availability should improve—Anthropic now has guaranteed infrastructure capacity and funding to scale up. For investors: Amazon stock has already jumped 20% in the past month on AI enthusiasm, making current valuations (36× price-to-earnings) roughly fair rather than cheap, so the stock looks like a hold rather than a bargain buy right now.
