More businesses pay for Anthropic's AI services than OpenAI's, according to new spending data from fintech platform Ramp. An analysis of business expense records shows 34.4% of participating companies paid for Anthropic services in May 2026, compared to 32.3% for OpenAI, a roughly 2-point lead that marks the first time Anthropic has topped OpenAI in documented enterprise adoption.

What Happened

Ramp, which processes expense data for thousands of companies, analyzed its clients' AI spending to determine which platforms had the most paying business accounts. Anthropic led OpenAI by 2.1 percentage points. TechCrunch reported the findings on May 13, 2026. The data reflects actual payment behavior, not survey sentiment. These are companies that signed up for Anthropic's API or Claude plans and expensed it through corporate accounts.

Why It Matters

The shift tracks with several moves Anthropic made in the past year. In April 2026, Claude for Creative Work launched with integrations for Adobe Creative Cloud, Blender, Autodesk, Ableton, and Canva. In May 2026, the company launched Claude for Small Business, a structured tier targeting teams without enterprise procurement budgets. The creative tool integrations appear to have broadened Claude's paying base into design studios, production companies, and creative agencies beyond just developer teams.

Creator Outcome: What to Try

If your team has not yet evaluated Claude for creative workflows, the market data is a useful signal. Claude's long context window and precise instruction-following make it effective for batch prompt generation, brief analysis, and caption writing at scale. For ComfyUI users, the new Claude LLM node in v0.21.1 lets you connect Claude directly into your workflow graph without a separate API layer, automating prompt creation as part of any image or video generation pipeline.
