ChatGPT Uninstalls Soar 295% After DoD Partnership News
U.S. uninstalls of the ChatGPT mobile app spiked 295% day-over-day on Feb. 28 after news of OpenAI’s deal with the U.S. Department of Defense, Sensor Tower data shows. That contrasts with ChatGPT’s typical 9% day-over-day uninstall rate over the prior 30 days. Competitor Anthropic’s Claude saw downloads rise (37% on Feb. 27 and 51% on Feb. 28) after Anthropic announced it would not partner with the defense department; Claude reached No. 1 on the U.S. App Store and surpassed ChatGPT in daily U.S. downloads, according to Appfigures and other providers. ChatGPT’s U.S. downloads fell 13% on Saturday and 5% on Sunday, and its 1-star reviews surged while 5-star reviews declined. Similarweb corroborated increased Claude activity but cautioned other factors could contribute.
Public backlash to an OpenAI–DoD partnership produced measurable app-store and review impacts and boosted a direct competitor; this affects user trust, market share between LLM apps, and app-store rankings relevant to AdTech/MarTech audience insights.

QuitGPT Surge Boosts Claude; OpenAI Loses Share
A surge of consumer backlash against OpenAI following its Pentagon deal — organized under the QuitGPT campaign — triggered large short-term declines in ChatGPT mobile metrics and a spike in interest for Anthropic’s Claude. Reported US ChatGPT mobile uninstalls jumped 295%, downloads fell 13%, and one-star reviews spiked; QuitGPT claims ~2.5 million signatures. Claude rose to #1 on US app stores, with downloads and sign-ups rising sharply; Anthropic reports rapid user and paid-subscriber growth and annualized revenue growth to about $20 billion. Despite the headline activity, the author argues the current boycott remains small relative to ChatGPT’s scale (~900 million weekly active users, ~50 million paying subscribers) and is a rounding error versus OpenAI’s revenue targets, though underlying multi-month market-share declines show structural competition is increasing between OpenAI, Anthropic, Google and others.
Claude's Popularity Soars After Pentagon Controversy
Anthropic’s Claude has seen a sharp rise in mobile installs and daily active users following the company’s public refusal to let the U.S. Department of Defense use its AI for mass surveillance or autonomous weapons, a stance that led to a Pentagon designation as a supply‑chain risk. App intelligence firm Appfigures reported U.S. daily installs on March 2 of about 149,000 for Claude versus 124,000 for ChatGPT. Market intelligence provider Similarweb estimated Claude’s iOS and Android daily active users at 11.3 million on March 2 — up 183% since the start of 2026 — while ChatGPT remained far larger at 250.5 million DAU. Claude’s web traffic rose 43% month‑over‑month in February and 297.7% year‑over‑year. Anthropic says signups and paid subscribers have also increased.
Claude Soars to No. 2 Amid Pentagon Controversy
Anthropic’s chatbot Claude surged to the No. 1 spot in Apple’s U.S. App Store free app rankings after heightened attention around the company’s negotiations with the Pentagon. Sensor Tower data show Claude moved from outside the top 100 at the end of January to mostly inside the top 20 in February, climbing rapidly to first place over several days and overtaking OpenAI’s ChatGPT. Anthropic said daily sign-ups set new records this week, free users are up more than 60% since January, and paid subscribers have more than doubled this year. The rise follows Anthropic’s attempts to negotiate safeguards limiting Department of Defense use of its models for mass domestic surveillance or fully autonomous weapons; President Donald Trump directed federal agencies to stop using Anthropic products and Defense Secretary Pete Hegseth labeled the company a supply‑chain threat. OpenAI later announced a separate agreement with the Pentagon, which CEO Sam Altman said includes related safeguards.
