Anthropic draft IPO filing lists about $110 billion in compute payments to Amazon

Per a draft Anthropic prospectus seen by the Wall Street Journal and reported on October 21, 2026, Anthropic plans payments of about $110 billion to Amazon for cloud computing capacity. Those payments would be owed even if Anthropic does not use all of the contracted capacity. The draft also cites similar figures for Alphabet and Microsoft, and puts Anthropic's long-term compute commitments above $600 billion. Risk disclosures state that Anthropic has pursued more capacity than certain large cloud partners have been prepared to offer, and that those partners view Anthropic as a competitor. For Amazon shareholders, the filing points to a large, concentrated AI customer commitment within AWS backlog, and to the possibility that this same frontier-model customer competes with Amazon's own AI models.
