Anthropic's Claude Jumps to No. 2 on Apple App Store After Pentagon Ban

Summary

Anthropic's Claude AI assistant app surged to the No. 2 position on Apple's top free U.S. apps chart on Friday, February 28, 2026, positioned between OpenAI's ChatGPT at No. 1 and Google's Gemini at No. 3. The dramatic rise in popularity came just hours after the Trump administration moved to block government agencies from using Anthropic's technology, with Defense Secretary Pete Hegseth designating the company as a supply-chain risk to national security.

The controversy stems from Anthropic's refusal to allow its AI models to be used for mass domestic surveillance or fully autonomous weapons, leading to a public clash with the Department of Defense. President Trump criticized the company on Truth Social, calling Anthropic executives "Leftwing nut jobs" for trying to enforce their Terms of Service. The ban means no U.S. defense contractor will be able to use Anthropic's tools, despite the company's assertion that its technology provides substantial value to the armed forces.

The app's rise suggests Anthropic is benefiting from the Streisand effect, with the controversy driving consumer interest. Claude had been ranked No. 131 in the U.S. on January 30 before steadily climbing throughout February. Celebrity endorsements may have also played a role, with pop singer Katy Perry posting support for Anthropic's Pro subscription on Friday night. Meanwhile, competitor OpenAI announced it had reached an agreement with the Defense Department on deploying its models, positioning itself as a more cooperative alternative.
