Amazon
Anthropic's largest investor and compute partner via AWS Trainium
Amazon has invested $8B into Anthropic and is Anthropic's primary training partner, anchoring Project Rainier — a massive Trainium2 cluster (hundreds of thousands of chips) in Indiana. The deal steers Anthropic toward AWS custom silicon rather than pure Nvidia, giving Amazon a hedge in the model layer against Microsoft/OpenAI and Google. Amazon's 2025 capex guidance exceeded $100B, dominated by AI infrastructure.
