Anthropic Overtakes OpenAI in Enterprise Adoption, Ramp Data Shows
rohanpaul_ai · x · 2026-08-13
According to Ramp's July corporate spend data, Anthropic has widened its lead over OpenAI in enterprise AI adoption, reaching 43.5% of eligible U.S. businesses compared to OpenAI's 39.7%.
Despite Anthropic's faster overall growth, its new Fable 5 model is seeing sluggish adoption, accounting for only 6% of tokens and 11.4% of model spend. In contrast, OpenAI's GPT-5.6 Sol represents 25% of tokens and 23% of spend. Price appears to be a major constraint, with Fable 5 costing roughly twice as much per 1M tokens as GPT-5.6 Sol.
