Anthropic has surpassed OpenAI in paid business adoption of artificial intelligence, marking a significant shift in the enterprise AI landscape. According to recent data from Ramp’s AI Index, Anthropic’s AI products were utilized by 34.4% of businesses on the platform in April 2026, compared to OpenAI’s 32.3%. This marks the first time that more U.S. businesses are paying for Anthropic’s Claude than OpenAI’s ChatGPT.
