Summary

Anthropic has surpassed OpenAI in business adoption, according to Ramp's May 2026 AI Index, which tracks corporate credit card spending. Anthropic now holds 34.4% of U.S. business adoption, compared to OpenAI's 32.3%. This marks a significant shift from May 2025, when OpenAI led with 32% and Anthropic had only 8%. The reversal is largely attributed to Anthropic's Claude Code, an autonomous coding tool that generated $2.5 billion in annualized revenue by February 2026. As of April 2026, Anthropic's annualized revenue reached over $30 billion, exceeding OpenAI's approximately $24 billion. OpenAI has responded by launching a $4 billion "Deployment Company" with 19 partners to accelerate Codex adoption within enterprises.

Key takeaway

For CTOs and VPs of Engineering evaluating AI vendor partnerships, Anthropic's recent surge in enterprise adoption, particularly with Claude Code, indicates a strong and rapidly expanding presence. You should assess Anthropic's offerings, especially its specialized coding tools, as they demonstrate significant traction and long-term integration potential within corporate infrastructures, influencing future procurement cycles and strategic AI investments.

Counsel's verdict on this

AIssential's Counsel cites this article in its editorial verdict on the decision it informs:

• Switch our enterprise stack from OpenAI to Anthropic? — Anthropic now leads business adoption at 34.4%, but its 98.95% API uptime and compute rationing risk critical enterprise workflows as OpenAI deploys agentic solutions.
