What happened
Anthropic's Claude chatbot recorded a 55% week-over-week increase in mobile app downloads by March 2, reaching 337,200 average daily downloads. This surge occurred as the US Department of Defence formally labelled Anthropic a "national security risk." Anthropic spokesperson Ryan Donegan stated the company is adding over one million new users daily, with free active users up 60% and paid subscriptions doubling since the year's start. Claude also became the No. 1 free app on the U.S. iOS App Store, rising from No. 42 in early February.
Why it matters
The "national security risk" designation creates a new constraint for defence contractors and procurement teams, requiring certification against using Anthropic's models in Pentagon-related work. This designation, issued by the US Department of Defence, effectively blacklists Anthropic AI for government use. The simultaneous surge in Claude's user adoption, with daily active users rising 26% to 9.4 million by March 2, occurs despite the government's designation. Security architects and platform engineers must now evaluate the implications of this "national security risk" label on existing and future integrations.
