Until recently, most people outside the technology industry had never heard of Anthropic. That changed almost overnight. A rapid sequence of headline-grabbing events has catapulted the AI company into mainstream conversation — and apparently straight to the top of millions of smartphone screens.
Over the weekend, Anthropic’s Claude application claimed the number one spot on Apple’s iPhone App Store, unseating OpenAI’s ChatGPT in a development that would have seemed unlikely just weeks earlier. The surge followed a very public confrontation with the Pentagon over artificial intelligence safety standards — a standoff that ended with the Department of Defense blacklisting Anthropic and designating it a supply chain risk after the company refused to sign a contract it felt crossed ethical boundaries.
FROM SILICON VALLEY FAVORITE TO GLOBAL CONVERSATION
The timing of Claude’s rise is striking. In early February, the app sat around position 42 on the App Store’s free app rankings. By the weekend following the Pentagon dispute — the same day President Donald Trump ordered federal agencies to stop using Anthropic’s products — it had climbed all the way to first place. On Android, ChatGPT continues to hold the top position on Google Play, though Claude has moved into fourth place, a significant jump in visibility.
Public sentiment appeared to follow. Supportive messages began appearing on the pavement outside Anthropic’s San Francisco offices, with passersby and apparent fans leaving notes of encouragement. Google search interest in the company reached its highest level since its founding. And in a sign of genuine cultural penetration, pop star Katy Perry was reported to have become a Claude user.
The company leaned into the momentum. Anthropic recorded an all-time high in new Claude sign-ups during the period. A new feature allowing users to import conversation history from rival AI tools was launched, and the ability for Claude to retain context across multiple conversations — previously limited to paying subscribers — was extended to free users. Demand was so intense that the service briefly went offline on Monday morning before being restored within a few hours.
A LONG ROAD TO CATCH CHATGPT
Despite the remarkable surge, the gap between Claude and ChatGPT in overall usage remains substantial. ChatGPT surpassed 900 million weekly users and draws more than 30 million weekly visitors to its website, compared to Claude’s approximately 3 million. Daily active usage tells a similar story — ChatGPT typically exceeds 20 million daily users, while Claude has historically remained below 2 million. In terms of chatbot referral traffic across the wider web, ChatGPT accounts for nearly 80%, with Claude at a fraction of that.
However, the trajectory shifted noticeably last week. Claude’s daily app downloads doubled compared to the previous week, a sign that the controversy translated into genuine, sustained interest rather than a fleeting spike.
ChatGPT fundamentally reshaped public awareness of AI when it launched in late 2022. Anthropic, built largely by former OpenAI employees, has long been respected within enterprise and developer circles for the quality of its coding tools and its principled approach to AI safety. Whether the current wave of attention marks a genuine turning point in its mainstream appeal remains to be seen — but for now, it has the attention of the world.
