Anthropic’s Claude has surged to the top of the U.S. App Store download charts, overtaking OpenAI’s ChatGPT in the wake of a high-profile dispute involving the Pentagon.
Claude reached the No. 1 spot Saturday after the Defense Department blacklisted Anthropic following a disagreement over military uses of its artificial intelligence models. The move came shortly after President Donald Trump criticized the company, and days before OpenAI announced it had secured its own Pentagon contract under revised safety terms.
The clash has drawn intense online attention and appears to have boosted consumer interest in Claude, at least in the short term. Social media users began encouraging others to delete ChatGPT after news spread that OpenAI had reached a deal with the Defense Department. An Instagram account called “quitGPT” quickly added thousands of followers, while a Reddit post urging users to cancel ChatGPT garnered tens of thousands of upvotes.
Anthropic had reportedly set firm boundaries on the use of its AI systems for mass surveillance or autonomous lethal weapons. After losing its Pentagon contract, the company said it would challenge any designation that posed supply-chain risks and signaled that it would not relax its safeguards.
OpenAI, maker of ChatGPT, announced its own Pentagon agreement hours later, saying the Defense Department had agreed to safety guardrails similar to those previously sought by Anthropic. The juxtaposition fueled online debate over the role of AI companies in military partnerships, with some users citing OpenAI leadership’s past political donations as part of their decision to switch platforms.
Despite Claude’s brief lead in downloads, industry data suggests the broader AI race remains highly competitive. Usage statistics compiled by OpenRouter show that over the past month, a dozen different AI models have outpaced OpenAI’s in certain categories. Claude’s Sonnet 4.5 model ranked fifth in February usage, while the top-performing model came from China-based MiniMax.
Even so, ChatGPT remains close behind Claude on app store rankings and retains a significant first-mover advantage in consumer awareness and global reach.
For Anthropic, the long-term business implications of the Pentagon fallout are unclear. However, the controversy has propelled Claude further into the mainstream spotlight. The company has already been gaining traction among enterprise clients following several product launches aimed at business adoption.
