Ramp's monthly index of company card and token spending found that Anthropic's most capable and most expensive model, Fable 5, saw limited business take-up in its first month, accounting for a small share of the tokens firms bought from Anthropic. Anthropic remains the most widely paid-for AI provider among U.S. businesses, ahead of OpenAI, while xAI grew fastest. Ramp's economist reads the pattern as an upper limit on what firms will pay for extra performance, and notes the token-usage sample skews toward technology companies.
What changed
Earlier months showed steady adoption gains for both OpenAI and Anthropic, with new premium models expected to pull spending upward.
