OpenAI is facing an unprecedented consumer exodus as the 'QuitGPT' movement gains momentum following its partnership with the US Department of Defence (DoD).
According to market intelligence from app analytics firm Sensor Tower, ChatGPT mobile uninstalls in the United States surged by 295 per cent on 28 February 2026, a drastic leap from the app's average daily churn of 9 per cent.
The backlash was ignited when OpenAI secured a contract to deploy AI on classified military networks just hours after rival firm Anthropic was blacklisted for refusing the same deal over ethics concerns.
The data reveals a sharp shift in the AI landscape as users prioritise digital ethics, with many pivoting to Anthropic's Claude, which reached the number-one spot on the US App Store for the first time on 2 March. Downloads also fell. Sensor Tower data shows installs dropped 13 percent on February 28, followed by a further 5 percent decline on March 1.
App Store ratings shifted dramatically over the same period. Sensor Tower reported that one-star reviews jumped 775 per cent on February 28 compared with the previous day. The following day saw an additional 100 percent rise in negative ratings. At the same time, five-star reviews fell by 50 per cent.
Many of the critical reviews raised concerns about the use of artificial intelligence in military contexts. Some users questioned transparency, while others raised broader ethical objections. Although OpenAI has previously worked with government agencies, the Pentagon partnership appeared to strike a different chord with segments of its consumer base.
The scale of the rating shift suggests this was more than routine dissatisfaction. It reflected wider unease about the role of AI in national security and warfare.
While ChatGPT was absorbing criticism, rival app Claude, developed by Anthropic, saw a surge in momentum.
Sensor Tower data shows Claude's US usage rose 51 per cent on February 28 compared with previous days. The app climbed to the top position in the Productivity category on the US App Store.
Online discussions linked the increase toAnthropic's reported decision to decline certain Department of Defence partnership requests. Although there is no confirmed causal link between that stance and the spike in downloads, social media posts frequently cited it as a reason for switching platforms. Screenshots circulating on Reddit and X showed users deleting ChatGPT and encouraging others to try alternatives.
