Anthropic announced Monday that Amazon has invested a further $5 billion in the company, bringing its total commitment to $13 billion. In return, Anthropic pledged to spend over $100 billion on AWS infrastructure over the next decade, securing up to 5 gigawatts of computing capacity built around Amazon’s Trainium chip series — including future generations not yet publicly available.
The deal mirrors a recent Amazon arrangement with OpenAI, structured partly as cloud infrastructure services rather than direct cash investment. Separately, venture capitalists have reportedly been circling Anthropic at a valuation of $800 billion or more, raising speculation of an imminent funding round.
Meanwhile, Axios reported that the National Security Agency is among the undisclosed organisations using Mythos Preview, Anthropic’s frontier cybersecurity model withheld from public release due to its offensive capabilities. The UK’s AI Security Institute has also confirmed access.
The NSA’s use of Mythos sits awkwardly alongside an ongoing Pentagon legal dispute, in which the Department of Defense has labelled Anthropic a supply-chain risk after the company refused to make Claude available for mass surveillance or autonomous weapons development.
Relations between Anthropic and the Trump administration appeared to be improving, however, after chief executive Dario Amodei met senior White House officials last week in talks described as productive.
