Anthropic Gains Ground Against OpenAI in First-Time Enterprise Deals

Anthropic won roughly 70% of head-to-head comparisons against OpenAI when enterprises evaluated AI platforms for the first time, according to Ramp's February 2026 AI Index. OpenAI recorded its largest monthly decline on record—1.5%—despite remaining the most widely used AI provider. The shift reflects growing enterprise preference for Claude, particularly among regulated industries like finance and insurance.
