Reports: Anthropic now surpasses OpenAI in enterprise adoption

Ramp said on May 13 that Anthropic had passed OpenAI in paid business AI adoption for the first time, with Anthropic used by 34.4% of businesses in its April index and OpenAI at 32.3%. Business Insider reported on May 23 that a survey of more than two dozen startup founders and venture capitalists found Claude Code had become the dominant AI coding tool inside startups. Together, the two reports point to a narrower story than a broad consumer-AI popularity contest: enterprise buyers appear to be rewarding tools tied directly to software delivery and day-to-day work. (ramp.com) ### What exactly changed in the enterprise rankings? Ramp’s AI Index tracks paid adoption across businesses on its corporate spend platform, and its May 13 release said Anthropic’s adoption rose 3.8% in April while OpenAI’s fell 2.9%. (businessinsider.com) Ramp described that as the first time Anthropic had moved ahead of OpenAI in business adoption. (ramp.com) Analytics Insight repeated those figures in a May 24 report and said the shift reflected growing enterprise demand for Claude and Claude Code. VentureBeat and Business Insider separately framed the change as a loss of OpenAI’s business lead, citing the same Ramp data. (ramp.com) ### Why does Claude Code keep coming up in these reports? Business Insider’s May 23 story centered on Claude Code, not the broader Claude chatbot, and said founders and investors increasingly viewed it as the default coding tool for startups. (analyticsinsight.net) One founder quoted in a widely mirrored version of the report, Chainguard CEO Dan Lorenc, said he expected to use less of “everything that’s not Claude Code.” (venturebeat.com) Anthropic’s own product materials describe Claude Code as an agentic coding system that can read a codebase, make changes across files, run tests and deliver committed code. Its enterprise page says the product is aimed at engineering teams that want centralized management, security controls and measurable deployment. (businessinsider.com) Those features help explain why the adoption story is showing up in procurement and engineering-stack conversations, though that linkage is an inference from the product positioning and the buyer data rather than a direct quote from Ramp.

OpenAI still accounted for 32.3% of paid business adoption in Ramp’s April data, which means the gap with Anthropic was narrow. (claude.com) The same numbers show a contested market rather than a runaway lead. Business Insider’s reporting also focused on startups and investors, not the full enterprise market, so the coding-tool story is strongest in software-heavy companies. (ramp.com) That matters because coding copilots and autonomous developer tools can spread inside companies differently from general-purpose chat products. ### Why would healthtech buyers care about a coding-tool race? Healthtech vendors building internal AI systems often start with engineering productivity before they expand into patient-facing automation, because internal tools carry fewer clinical and compliance risks. (businessinsider.com) That is an inference from how enterprise coding tools are being adopted and from Anthropic’s enterprise positioning, not a direct claim in the cited reports. Anthropic’s enterprise materials emphasize secure deployment and centralized controls, while Ramp’s data suggests buyers are paying for the stack they find most useful in production. For healthtech companies, that can affect which vendor gets embedded in developer workflows, budget lines and internal governance reviews before any broader rollout. ### What should readers watch next? (businessinsider.com) Ramp’s next AI Index releases will show whether Anthropic’s lead holds beyond one month or whether OpenAI regains ground after April’s shift. Anthropic is also continuing to market Claude Code to enterprise engineering teams through its product and enterprise pages, which will be one public place to watch for customer references and deployment signals.
