100-word summary
The Department of Defense just did something unprecedented: it labeled a U.S. AI company a supply-chain threat to national security. Anthropic, maker of Claude, faces the same designation previously reserved for foreign adversaries. The move kills a $200 million contract and forces Pentagon contractors to rip out Claude from defense systems within six months. Anthropic sued March 9, claiming First Amendment violations. Meanwhile, OpenAI swooped in to fill the void with its own Pentagon deal. The real story? Washington just invented a new way to pick winners in the AI race, weaponizing national security law against domestic companies for the first time.
