Anthropic now has more business customers than OpenAI, according to Ramp data
A survey compiled from fintech firm Ramp’s clients’ expense data shows 34.4% of participating businesses are paying for Anthropic services, more than any other AI lab, while only 32.3% pay for OpenAI.
For the first time, Anthropic has more verified business customers than OpenAI, according to this month’s AI Index from the fintech firm Ramp.
The survey, compiled from Ramp’s clients’ expense data, shows 34.4% of participating businesses are paying for Anthropic services, more than any other AI lab, while only 32.3% pay for OpenAI.
It is the first time Anthropic has held the top position.
“Anthropic has already been in the lead amongst the high adoption groups like finance, tech, professional services,” Ramp economist Ara Kharazian told TechCrunch. “It’s across the other firms where OpenAI still has a lead, but that has been shrinking over the past couple of months.”
Because the index only represents companies that use Ramp, it’s not a perfect proxy for the marketplace at large. Still, the sample includes more than 50,000 companies, making it both broad and diverse enough to carry weight.
More importantly, the general trend can be seen across the industry. On OpenRouter’s leaderboard , which samples a different portion of users, OpenAI last ranked above Anthropic in December 2025.
According to Ramp’s figures, the past 12 months have been particularly transformative for Anthropic. In May 2025, a mere 9% of businesses were paying for Anthropic products, a figure that climbed 26% in the following 12 months. Over the same period, OpenAI’s share declined by 1%, and the overall share of businesses using some kind of AI product increased by 9%.
Kharazian is skeptical about whether this advantage will last, for reasons he explained in a blog post, but said the success of the past year was proof that Anthropic had chosen a good strategy.
“What Anthropic did worked really well,” Kharazian told TechCrunch, “which was — start with a very technical customer base, focus on their needs, really succeed in execution and then start broadening out through tools like Cowork.”

Editorial analysis
Anthropic's rise over OpenAI, as indicated by Ramp's data, reflects the dynamic changes in the AI market, particularly in sectors like finance and technology. For the Brazilian tech sector, this shift may signal an opportunity for local companies seeking more specialized and tailored AI solutions. By focusing on a technical audience and expanding its offerings, Anthropic could inspire Brazilian startups to adopt similar strategies, prioritizing customization and effective execution.
Moreover, OpenAI's declining market share suggests that competition in the AI space is intensifying. This could lead to increased innovation as companies seek to differentiate their offerings and better meet customer demands. For the Brazilian tech ecosystem, this may result in a push for the development of AI solutions that cater to specific niches, fostering a more competitive and diverse environment.
Looking ahead, it will be crucial to monitor how Anthropic maintains its advantage and whether OpenAI can reclaim its position. The answer to this question may influence investment and product development decisions among Brazilian companies operating in the tech sector. Additionally, the evolution of customer preferences regarding AI providers could shape the direction of technological innovations in the country, especially if local companies begin to adopt solutions that prioritize ethics and safety—characteristics that Anthropic emphasizes in its approach.
Finally, the increasing adoption of AI tools among businesses, as indicated by the overall 9% rise in AI product usage, suggests that the Brazilian market is preparing for a significant transformation. Companies that quickly adapt to these changes and embrace emerging technologies will be better positioned to thrive in an increasingly data-driven and AI-oriented future.
