Anthropic's Claude overtook OpenAI's ChatGPT to claim the top spot on the Apple iPhone’s US free app charts Saturday evening after the company's public standoff with the Department of Defense.
The climb was rapid: the Claude app ranked sixth on Wednesday, fourth on Thursday, and first by Saturday — tracking almost exactly with the Pentagon dispute reaching its peak.
As of this writing, Sunday, March 1, the Claude app is #1 overall in the US iPhone App Store.
Anthropic says daily signups broke the company's all-time record every day during the final week of February, with free users up more than 60% since January and paid subscribers more than doubling this year.
The dispute with the Pentagon
Anthropic refused to agree to unconditional military use of Claude, drawing specific red lines against mass domestic surveillance and fully autonomous weapons. Defense Secretary Pete Hegseth responded by designating Anthropic a supply-chain risk to national security, effectively banning the company from doing business with the Pentagon. President Trump also directed federal agencies to phase out Anthropic products within six months.
Shortly after the ban was announced, Sam Altman, CEO of OpenAI, announced a new deal with the Pentagon, claiming it includes the same prohibitions Anthropic had sought. That apparent contradiction (the government blacklisting one company for a position it then agreed to with another) fueled backlash across Reddit and X, with users publicly posting cancellation receipts and Claude signup confirmations.
Some important context, though: ChatGPT still commands a dramatically larger user base, and download spikes tied to news cycles tend to be temporary. The more durable story may be that Claude was already on a steep growth arc before the dispute. Anthropic's Super Bowl ads in early February, which pointedly mocked ChatGPT's decision to introduce ads to free users, had already given the app more attention.
What the Pentagon conflict provided was something no advertising campaign could manufacture: a simple, resonant narrative.
