Anthropic narrows OpenAI lead as US enterprise AI uptake accelerates
Anthropic is narrowing the gap with OpenAI in US enterprise AI adoption, with Ramp data showing nearly a third of US businesses paid for Anthropic tools in March (up from February) while OpenAI’s paid share hovered around 35% and was flat. The growth is driven by Anthropic’s Claude Code products and a broader set of plug-ins that automate professional work, helping it expand beyond developers. OpenAI remains dominant in consumer usage, but its growth has cooled in some areas. Anthropic has claimed about $30 billion in annualized revenue, signaling rapid enterprise traction and a shift in momentum toward its platform.
