Claude Overtakes ChatGPT in US App Store Following Pentagon Deal Controversy

Anthropic's Claude Claims Top Spot in App Rankings

Anthropic's Claude has surpassed OpenAI's ChatGPT to become the number one free iPhone app in the United States Apple App Store, marking a significant shift in the competitive AI chatbot landscape. The milestone, achieved on Saturday, represents the first time Claude has outranked its primary competitor in the US market.

According to data from Appfigures, an app intelligence firm, Claude experienced explosive growth with US downloads surging 240% month-over-month in February. The AI assistant attracted 1.1 million more downloads than the previous month, demonstrating unprecedented momentum in user adoption.

Claude now holds the top ranking as the number one free iPhone app across five markets: the United States, Canada, Germany, Ireland, and Luxembourg. An Anthropic spokesperson noted that just one month prior, Claude didn't even appear in the top 40 of the US Apple App Store.

Anthropic's Mike Krieger announced on Tuesday that "more than a million people are now signing up for Claude every day," welcoming new users who are integrating the AI assistant into their daily workflows.

Pentagon Deal Fallout Impacts OpenAI

The dramatic reversal in app rankings coincides with mounting criticism of OpenAI's controversial agreement with the Pentagon. OpenAI CEO Sam Altman publicly acknowledged the deal was "rushed" and represented poor optics for the company.

In an internal message released publicly on Monday evening, Altman admitted the timing was problematic, as the Pentagon announcement came just hours after Anthropic was effectively blacklisted from US government contracts. "One thing I think I did wrong: we shouldn't have rushed to get this out on Friday," Altman wrote. "The issues are super complex, and demand clear communication. We were genuinely trying to de-escalate things and avoid a much worse outcome, but I think it just looked opportunistic and sloppy."

Altman confirmed that OpenAI had reopened negotiations with the Department of Defense to secure stronger protections and clarify the company's principles regarding AI deployment.

Anthropic's Principled Stand

Anthropic CEO Dario Amodei revealed that negotiations with the Pentagon collapsed because the Department of Defense demanded unrestricted access to AI models. Anthropic insisted on safeguards to prevent misuse of its technology in fully autonomous weapons systems or mass surveillance of American citizens.

In response to Amodei's refusal, Defense Secretary Pete Hegseth threatened to formally designate Anthropic as a supply chain risk, a label that would prohibit the AI startup from working with government agencies and defense contractors. Amodei stated his company would challenge such action in court.

ChatGPT Maintains Global Dominance

Despite the recent setback, ChatGPT remains the global leader among AI chatbots by a substantial margin. On the same day OpenAI announced its Pentagon deal, the company reported that ChatGPT had exceeded 900 million weekly active users. For comparison, Google disclosed during its February 4 earnings that Gemini had 750 million monthly active users.

According to Appfigures estimates, ChatGPT has been downloaded approximately 8.7 million times in the US through the end of February 2026, compared to Claude's estimated 2.1 million downloads during the same period.

The download estimates are based on AI models that analyze observed trends across the Apple App Store and Google Play Store, excluding re-installations and multiple downloads by individual user accounts.

Near the end of 2025, Altman declared a "code red" to allocate additional resources to ChatGPT amid concerns that Gemini's latest update had surpassed ChatGPT's capabilities. Whether OpenAI can recover from this self-inflicted controversy as quickly as it responded to competitive threats remains uncertain.

Coinasity's Take

This development highlights how quickly user sentiment can shift in the AI sector when companies face ethical controversies. Anthropic's principled stance on AI safety and military applications resonated with users concerned about responsible technology development. While ChatGPT's global dominance remains intact for now, OpenAI's rushed Pentagon deal and subsequent public apology demonstrate the reputational risks of prioritizing government contracts over transparent ethical policies. The crypto and tech communities have historically valued decentralization and user autonomy—principles that appear to align more closely with Anthropic's position in this dispute. This situation may serve as a cautionary tale about the importance of maintaining user trust in the rapidly evolving AI landscape.
