Robust Data-Driven Insights
The survey, while representative of the subset of companies using Ramp services, spans a broad and diverse group, thereby lending credence to the emerging industry trend. Data from OpenRouter’s leaderboard further corroborates this pattern, with OpenAI last ranking above Anthropic in December 2025.
Strategic Execution And Future Prospects
Anthropic’s growth accelerated significantly over the past year. In May 2025, approximately 9% of businesses tracked by the index used Anthropic products. That figure increased by 26 percentage points over the following 12 months. During the same period, OpenAI’s share declined by 1%, despite overall AI adoption across businesses increasing by 9%. Kharazian attributed Anthropic’s growth to its enterprise-focused strategy and concentration on technical customers before expanding into broader business use cases through additional tools and services.
