Anthropic Plans to Spend $518 Billion on Cloud and Data Centers. More Than $100 Billion Is Already Promised to Amazon.

Anthropic's draft IPO prospectus reveals $518 billion in planned cloud and infrastructure spending over coming years, with $110 billion committed to Amazon Web Services through 2036. Despite large operating losses, Anthropic's revenue is growing rapidly (14-fold year-over-year in Q2 2026), making the AWS commitment appear manageable. However, concentration risk exists as nearly 25% of 2025 revenue came from just two customers without long-term contracts.
