Pentagon Blacklists Anthropic After AI Guardrail Standoff

Focusing Facts

  1. President Trump’s Truth Social directive set a six-month phase-out clock for every federal agency now using Claude, affecting at least five departments and a $200 million DoD contract.
  2. Defense Secretary Pete Hegseth’s order bars any firm that does business with the U.S. military from “conducting any commercial activity with Anthropic,” instantly freezing Claude out of the entire defense industrial base.
  3. Hours later, OpenAI announced a new Pentagon contract to deploy its models on classified networks, claiming written prohibitions on surveillance and autonomous weapons that mirror Anthropic’s rejected terms.
