Paying Claude consumers have grown by roughly 75% since January 2026, according to Indagari data. On DataCamp, demand for Claude courses now outpaces ChatGPT three to one, as both Anthropic and OpenAI head toward public listings.
Key Takeaways
- Paying Claude consumers are up about 75% since January 2026.
- Claude course demand on DataCamp beats ChatGPT in a 3 to 1 ratio.
- ChatGPT still leads by a wide margin in absolute paying users.
75% in Five Months: Claude Climbs Into Consumer
The center of gravity is moving on terrain that had been resistant to Anthropic so far. Paying Claude consumers gained around 75% between January and May 10, 2026, according to Indagari.
The measurement rests on anonymized credit card transactions from 28 million U.S. consumers. The weekly granularity tracks revenue month by month, and the Claude curve keeps climbing all the way to the cutoff.
The signal matters for two reasons. First, the consumer market had been ChatGPT’s stronghold. Second, Anthropic had already pulled ahead of OpenAI in enterprise, without managing to translate that lead into the paying consumer base.
The trigger points to March 2026. Anthropic publicly declined to support mass surveillance and autonomous weapons use cases, and the paying subscriber curve accelerated right after, suggesting the editorial posture is converting in a measurable share of the audience.
The gain does not erase the gap. ChatGPT still holds substantially more paying users in absolute terms, and Anthropic still needs to prove the curve survives the spring 2026 surge.
DataCamp and the Training Effect: 3 to 1 Against ChatGPT
The clearest signal does not come from the consumer marketplaces but from training platforms. On DataCamp, “Claude” is now the number one search term, ahead of “AI” itself.
Claude course demand crushes ChatGPT by a 3 to 1 ratio. Over the last thirty days, interest in Claude courses jumped 18x, well above Anthropic’s overall audience trajectory.
ChatGPT still owns the corporate training segment. The programs commissioned by employers remain dominated by OpenAI courses, mirroring the historical installed base inside large accounts.
The gap between DataCamp and corporate training tells a layered story. Individuals are learning Claude on their own, while learning departments keep buying ChatGPT for their staff. That divergence usually ends up reshaping internal procurement.
A recent case illustrates the need for caution. Samsung pushed its entire Korean workforce onto ChatGPT and Codex, proof that large enterprise rollouts still hinge on global contracts, not on developer favor.

March 2026 and the IPO: A Moral and Financial Lever
The calendar makes the data particularly sensitive. Anthropic and OpenAI are both preparing public offerings, and every consumer market gain feeds into the eventual valuation.
Anthropic’s March 2026 stance, refusing mass surveillance and autonomous weapons, acted as a pivot. A share of paying users now report choosing Claude for that positioning, turning the safety posture into a measurable commercial argument.
The regulatory backdrop complicates the read. The U.S. government banned Mythos 5 and Fable 5 for foreign nationals in June 2026, cutting Anthropic off from a slice of its international audience exactly when the paying curve is accelerating at home. Anthropic has been adding transparency signals of its own, with a Claude watermark now covering all generated text.
Sensor Tower data referenced alongside the Indagari numbers says Claude is growing well across all platforms this year but remains a long way behind ChatGPT in absolute volume. The trajectory is clean, the gap is not closed.
In the short term, Anthropic can lean on the Indagari and DataCamp numbers as marketing fuel into its IPO. In the medium term, the real test will be turning consumer momentum into recurring revenue at scale, in a market where ChatGPT still benefits from default placement.
