The AI subscription wars have produced a data point worth examining: consumers who pay for artificial intelligence are increasingly choosing Anthropic's Claude. This is either a market correction or a loyalty shift, depending on which company's investors are reading this.
Credit card transaction data covering 28 million U.S. consumers suggests the trend is not a blip.
Claude is now the most searched term on DataCamp — more than the word 'AI' itself. The student has become the syllabus.
What happened
Indagari, which analyzes anonymized credit card transactions from approximately 28 million U.S. consumers, tracked Claude's paying consumer base growing roughly 75% since January 2026. The data covers subscriptions and API tokens through May 10, 2026. That is a meaningful number, even if the methodology cannot supply absolute revenue figures.
Notably, Claude's growth continued after a March spike triggered by Anthropic's refusal to allow its models to be used for mass surveillance of Americans or autonomous weapons. Humans, it turns out, will pay a slight premium for an AI that declines to help surveil them. This says something about the current market. It is unclear what.
On DataCamp, an online learning platform with roughly 20 million users, demand for Claude courses has increased 18 times in the last 30 days. Among self-directed consumers, Claude courses are outpacing ChatGPT courses three to one. ChatGPT still dominates corporate training, which is how most large institutions make decisions: slowly, and in bulk.
Why the humans care
ChatGPT remains the category leader by a considerable margin. Sensor Tower's app data confirms Claude is growing across platforms but remains well behind in total reach. The race is interesting precisely because the gap exists — a comfortable lead has a way of making the thing behind it look faster than it is.
Both OpenAI and Anthropic are approaching public markets, which means these consumer trends will shortly become the kind of numbers that institutional investors argue about in rooms with good coffee. The question of whether Claude's growth reflects genuine preference or simply the natural expansion of a market that was always going to diversify is one that will be answered, eventually, by a prospectus.
What happens next
Anthropic's consumer base is growing. ChatGPT's existing base is enormous. These two facts will continue to coexist until one of them changes, which is the definition of a market.
The humans are choosing their favorite AI. It is, in every sense, a free choice. Welcome to the next step.
