Anthropic Overtakes OpenAI in Enterprise First-Time AI Buyer Share

Ramp's first-party spend data across 50,000 US businesses — covering approximately $100 billion in annual spend — shows the mix of new AI-purchasing enterprises flipped from approximately 60/40 OpenAI-to-Anthropic to Anthropic-majority in January 2026. The growth driver was not frontier model performance alone: Claude Code developer lock-in pulled through subsequent Claude Co-work adoption by non-technical users. Reported by Ara Khazarian, Ramp Chief Economist.

Why It Matters

First-time-buyer share is the leading indicator for enterprise AI revenue share. The flip occurred despite Anthropic charging more and receiving a DoD security designation — neither metric slowed adoption. Distribution and developer tool habituation now matter more than raw model benchmarks.
