Story summary

The U.S. government ordered Anthropic to block foreign nationals from its Fable 5 and Mythos 5 models, prompting a total shutdown.
Anthropic warned that a U.S. export ban on the models could stall all frontier AI deployments.
Pentagon chief information officer Kirsten Davies said national-security considerations outweigh revenue concerns.
The Pentagon added Anthropic to a supply-chain blacklist that will limit its federal contracts later this year, threatening its fall-2026 IPO near $1 trillion.

History

Historical Context

After the 1999 Export Administration Regulations barred Cray Inc.’s supercomputers from China, the Commerce Department again tightened controls on advanced chips on Oct 7 2022, adding 28 Chinese entities to the Entity List. Pentagon CIO Kirsten Davies’ blacklist of Anthropic mirrors that precedent, showing U.S. national-security concerns still shape global frontier-technology markets today.
