ChatGPT Downloads Fall as Anthropic's Claude Surges in App Charts

OpenAI’s ChatGPT mobile app has recently seen a slowdown in download growth while rival Anthropic’s Claude has recorded a notable spike in installs, with third-party app data showing Claude overtaking ChatGPT in some markets.

The shift accelerated in early March 2026: app intelligence firms reported that Claude’s daily U.S. downloads reached roughly 149,000 on March 2, compared with about 124,000 for ChatGPT, and several sources noted sharp, short-term increases in ChatGPT uninstalls. These figures reflect user behavior around a concentrated news cycle rather than long-term engagement metrics.

For both companies, downloads are an incomplete but useful signal. Anthropic has said daily active users and paid subscribers rose markedly in the weeks following the surge, suggesting some conversion beyond casual installs. Nevertheless, analysts caution that installs do not automatically translate into sustained active use or revenue, and retention will be the key test.

The downloads surge coincided with public disputes involving U.S. defense agencies and AI vendors. The Pentagon’s decisions and related government statements increased scrutiny on Anthropic and OpenAI, feeding user campaigns and social-media movements that encouraged switching away from or toward particular platforms. Meanwhile, reporting on OpenAI’s arrangements to supply agencies via major cloud providers kept the sector in the headlines.

Market observers say the immediate winner of a publicity-driven download spike is unclear for the long term. Many expect a multi-provider landscape to settle where usability, integration into enterprise workflows and regulatory approvals matter more than short-lived download charts. Ongoing legal and policy developments will likely shape enterprise contracts and consumer trust in the months ahead.
