Anthropic now has more business customers than OpenAI, according to Ramp data
The business move
Anthropic has surpassed OpenAI in verified business customers, according to this month’s AI Index report from Ramp. For the first time, the fintech firm’s data shows Anthropic with a higher number of paying business accounts than its high-profile rival. While OpenAI remains dominant in user and developer mindshare, Anthropic’s traction among businesses using AI for operational purposes appears stronger in this metric.
Why it matters
More verified business customers mean Anthropic is gaining ground in real-world AI deployments. This shift signals businesses are actively choosing Anthropic’s models and offerings for commercial use cases over OpenAI’s at a growing pace. For founders and operators, this could affect vendor decisions, contract negotiations, and integration priorities. Investors may interpret it as an indicator of where enterprise demand is consolidating, pressuring OpenAI to sharpen its B2B strategy. It also suggests Anthropic’s approach, which emphasizes safety and robustness, resonates with companies that value trustworthiness over hype.
Who gains and who gets squeezed
Anthropic emerges as the immediate beneficiary, enhancing its market credibility and expanding its customer base. This strengthens its position in enterprise AI and could accelerate onboarding of larger clients who require verified relationships. OpenAI, despite its dominance in developer ecosystems and broad AI experimentation, faces increasing competition in the commercial enterprise segment. Companies seeking business-grade AI solutions may feel more inclined to explore Anthropic’s offerings due to this momentum, which could reduce OpenAI’s market share or slow its B2B growth rate.
What to watch next
Watch Ramp’s future AI Index releases for whether Anthropic can maintain or widen this lead and how OpenAI responds. Pay attention to customer churn rates, contract sizes, and the nature of deployments to evaluate if this is a durable shift or a temporary anomaly. Also look for enhancements in Anthropic’s product suite or pricing that make it more attractive to businesses. Finally, monitor whether this trend influences partnerships, integrations, or regulatory scrutiny regarding AI vendor reliability for enterprise users.
