E-commerce and tech giant Amazon is investing up to $25 billion in Claude bot maker Anthropic, expanding its artificial intelligence infrastructure.

Amazon has already invested $8 billion in Anthropic over the past few years, and the new financial commitments further expand that investment. It includes an initial $5 billion, with more tied to milestones.

Anthropic said on Monday that it will spend over $100 billion on Amazon Web Services over 10 years, using Trainium chips to power its Claude AI models. It has secured up to 5 gigawatts of capacity to scale operations.
