OpenAI Leads Enterprise AI Adoption Surge
Ramp data shows OpenAI leading US enterprise AI adoption in December 2025, with 36.8% of businesses paying for OpenAI products as overall paid AI adoption rose to 46.6%. Ramp's analysis of corporate billing across 50,000+ US firms also found Anthropic at 16.7% and Google at 4.3%, noting paid-transaction figures likely understate total usage.
Key Points
