100-word summary
The Department of Defense designated Anthropic a "supply-chain risk to national security," blocking DoD use of Claude immediately. But Microsoft, Google, and AWS all say commercial customers can keep using the model on their platforms. The DoD won't clarify whether the ban extends beyond its own contracts, leaving companies to draw their own lines. Anthropic plans to challenge the designation in court, setting up a fight over how defense rules apply to commercial AI. Meanwhile, over a million people per day signed up for Claude that week. Turns out getting banned by the Pentagon is better marketing than any Super Bowl ad.
