Anthropic Claude gains 75% in paid consumers as AI chatbot market shifts from ChatGPT dominance

Anthropic Claude Sees 75% Growth in Paid Consumers

Anthropic Claude is experiencing a dramatic shift in the AI chatbot market, with credit card transaction data from Indagari revealing a 75% increase in paid consumers and revenue since January 20261

1

. The analysis, which examines billions of anonymized credit card transactions from approximately 28 million U.S. consumers, shows Claude's paying customer base growing month by month through May 10, 20261

. This data covers payments for consumer subscriptions and API usage, signaling that Anthropic has expanded beyond its perceived niche of enterprise developers and Claude Code users into a broader consumer market.

The growth trajectory continued even after a March spike when Anthropic publicly refused to allow its models to be used by the Trump Administration for mass surveillance and autonomous weapons2

2

. Additional evidence of Claude's rising consumer adoption comes from DataCamp, an online education platform with about 20 million users, where "Claude" has become the most searched term on the site, surpassing even "AI" itself1

. Among self-directed consumers on the platform, demand for Claude courses is outpacing OpenAI ChatGPT by three to one, with course demand increasing 18 times in the last 30 days alone2

Claude vs ChatGPT: The User Base Growth Paradox

While Anthropic Claude demonstrates impressive momentum with paid consumers, OpenAI ChatGPT maintains a commanding lead in overall user numbers. According to IDC Research Vice President Arnal Dayaratna, ChatGPT has more than 900 million weekly active users worldwide4

. In contrast, Claude has approximately 40 million to 60 million weekly active users5

, though some estimates place monthly users around 56 million3

.

Similarweb data reveals that Claude's website traffic jumped roughly 770% between September 2024 and March 2026, while ChatGPT's web visits grew about 84% over the same period—meaning Claude expanded at roughly nine times the pace3

. However, audience overlap data suggests this growth isn't primarily coming from users abandoning ChatGPT. Instead, the vast majority of Claude users also use ChatGPT in the same month, indicating consumers are adding Claude alongside OpenAI's chatbot rather than replacing one with the other3

. This multi-platform landscape suggests the AI market is expanding rather than following a winner-takes-all pattern.

Enterprise Revenue Growth Tells a Different Story in the AI Revenue Race

Despite trailing significantly in consumer adoption, Anthropic may be outperforming OpenAI in monetization. IDC estimates Anthropic's annualized revenue stands between $40 billion and $50 billion, with consumer subscriptions accounting for less than $2 billion4

4

. The firm's revenue appears concentrated in enterprise subscriptions, Claude Code seats, and API consumption. Anthropic itself announced in May 2026 that its annualized run-rate revenue had surpassed $47 billion4

4

.

In comparison, IDC estimates OpenAI generates between $30 billion and $40 billion in annualized revenue, including roughly $10 billion to $13 billion from consumer subscriptions and as much as $20 billion from API and platform-related usage4

4

. Counterpoint Research estimated in April 2026 that Anthropic captured 31.4% of global LLM revenue during the first quarter, ahead of OpenAI's 29% share4

. The research firm also found Anthropic generated the highest average monthly revenue per user at $33.3, far above OpenAI's $2.24

AI Market Dynamics Shift as Both Companies Prepare for Public Markets

The consumer momentum matters because both Anthropic and OpenAI are preparing to go public. Anthropic filed confidentially for an IPO in June at a valuation approaching $965 billion, after securing a $65 billion Series H funding round in May that made it the world's most valuable startup2

. Investors examining the prospectus will want to see that growth extends beyond API contracts into the consumer market where recurring subscription revenue is more predictable2

.

The picture is complicated by Anthropic's ongoing conflict with Washington. The U.S. government ordered Anthropic to shut down its most powerful models, Fable 5 and Mythos 5, earlier this month over a disputed jailbreak, forcing a global shutdown just three days after Fable 5 launched2

2

. So far, the clash appears to have helped rather than hurt consumer adoption, echoing the March pattern where controversy drove sign-ups2

2

. Every independent data source examining the question in 2026 points in the same direction: Claude is gaining paid consumers at a rate that no longer looks like a niche2

2

. For investors and industry watchers, the key question is whether users are increasingly relying on multiple AI assistants for different tasks, which could reshape competitive dynamics away from traditional winner-takes-all technology battles3
