Claude App Store Surge

In late February 2026, Anthropic's Claude app surged to No. 1 in the U.S. Apple App Store free apps category, dethroning ChatGPT for the first time. The rise was driven by a combination of superior model performance, new product features, and a viral political moment stemming from Anthropic's confrontation with the U.S. Department of Defense. 1)

ChatGPT's first-mover advantage was eroding amid the Pentagon backlash and competitive pressure from both Claude and Google's Gemini. 6)
