Anthropic raised $5 billion in a strategic round at an undisclosed valuation.
TechCrunch reported on 2026-04-20 that Amazon led the round with no co‑investors and the cash will fund up to 5GW of AWS capacity, while Anthropic has pledged to spend over $100 billion on cloud services for the next ten years.
Anthropic’s Claude Model and 5GW Capacity
Anthropic, founded in 2020 by former OpenAI researchers, builds the Claude family of large‑language models and targets enterprise AI users; the company has not disclosed specific traction metrics, but its commitment to 5GW of new computing power underscores a push to scale model training and inference.
Amazon’s Strategic Bet: $5B Lead Investment
Amazon’s decision to lead rather than co‑invest reflects higher conviction, echoing a prior $110 billion funding round where it contributed $50 billion to OpenAI and valued the chatbot maker at $730 billion pre‑money; the current deal also locks Anthropic into using Trainium2 through Trainium4 chips, with Trainium3 released in December and future chips optioned.
OpenAI’s $110B Funding Round Compared
The OpenAI round valued its partner at $730 billion, while Anthropic’s undisclosed valuation sits beside a $13 billion total Amazon investment; this contrast highlights Amazon’s broader strategy of pairing cash infusions with massive cloud spend commitments across AI leaders.
Anthropic’s agreement secures up to 5GW of AWS compute and aligns its growth with Amazon’s custom Graviton CPUs and Trainium AI accelerators.
