- Anthropic has more verified business customers than OpenAI, with 34.4% of Ramp’s 50,000+ client companies using its services as of the latest AI Index
- OpenAI’s share of business customers declined by 1% over the past year, falling to 32.3% while Anthropic’s surged from 9% to 34.4% in the same period
- Ramp economist Ara Kharazian attributes Anthropic’s growth to a focused strategy on technical customers and tools like Cowork, noting its lead in finance, tech, and professional services
Why it matters: Anthropic gains enterprise traction and revenue momentum, while OpenAI loses ground despite brand recognition. The 2.1-point gap among 50,000 companies signals a material shift in AI vendor preference, affecting future enterprise contracts and pricing power.
