Most of Anthropic's revenue comes from businesses.

Judged as of 2026-05-09. True: credible figures from around that date (Anthropic financial disclosures, investor materials, or reliable press reporting of its revenue mix) show that more than 50% of Anthropic's revenue came from business customers: enterprise and API customers, including businesses reached through cloud partners. Consumer subscriptions such as individual Claude Pro or Max plans do not count as business revenue. Mostly true: business revenue is clearly a majority but the reported share is unclear or the sources disagree slightly. Mixed: business revenue is shown to be about half (roughly 45–55%) with no clear majority. Mostly false: business revenue is a large share but less than half, or a majority only under a stretched definition of business. False: the evidence shows that most of the revenue came from consumers or other non-business sources.

   “with first-half revenue rising 1,300% to $16.28 billion. About $13.1 billion of that, or roughly 80%, comes from enterprise customers paying consumption-based fees rather than individual subscriptions.”

E1 reports that roughly 80% of Anthropic's first-half revenue came from enterprise customers, but it does not say which year's first half that is. So the evidence does not show the revenue mix around the claim date of 2026-05-09, which the criteria require.
