According to trend data from credit card transaction analysis company Indagari, consumers who pay for AI have been increasingly choosing Anthropic’s Claude. Indagari analyzes billions of anonymized credit card transactions from about 28 million U.S. consumers. The data, covering weekly transactions from 2025 through May 10, 2026, shows Claude’s paying consumers and revenue growing month by month, currently up about 75% since January 2026 among this segment. Gains continued even after a growth spike in March, when Anthropic refused to allow its models to be used by the Trump administration for mass surveillance of Americans and autonomous weapons. DataCamp, an online education platform with about 20 million users, reports that “Claude” is now the most searched term on its site, even more than “AI.” Among self-directed consumers, demand for Claude courses is outpacing ChatGPT by three to one, and demand for courses on Claude has increased 18x in the last 30 days alone. However, recent data from Sensor Tower shows Claude still a long way behind ChatGPT, and Indagari data indicates ChatGPT still has many more paying users.
