Two months in, Anthropic's most expensive model is about 11 percent of what customers spend — and the cheap one just overtook it
Corporate card data from Ramp, reported by George Hammond at the Financial Times and detailed on 23 August, puts numbers on something buyers have been doing quietly all summer. Fable 5, Anthropic's flagship released in June at roughly $10 per million tokens, has flattened at about 11 percent of identified spending on Anthropic products — and only about 6 percent of tokens actually purchased, meaning its share of the money is nearly twice its share of the work. Vercel's AI gateway showed a similar picture in July, with Fable 5 at 13.2 percent of gateway spend. Claude Opus 5, released on 24 July at $5 per million input tokens and $25 per million output, has now passed Fable 5 in corporate spending outright. The same Ramp data puts Anthropic at 43.5 percent of US business AI adoption against OpenAI's 39.7 percent, with Anthropic's annualised revenue rate reported at $65 billion as of July. One caveat worth carrying: Ramp's customer base leans toward technology companies, so this is a lens on the market rather than a census of it.
