Ramp data indicates faster OpenAI growth among US business users
OpenAI is gaining momentum among US business users in Ramp’s latest spending data, even though Anthropic remained ahead in July. The corporate card and expense-management provider tracks more than 70,000 American businesses that spend billions of dollars through its bill-pay and corporate-card products.
Anthropic held nearly 44% of AI market share among Ramp’s paying business customers in July, compared with nearly 40% for OpenAI. The gap followed Anthropic’s May move into the lead, when it reached 41% while OpenAI stood at 39%.
Ramp sees faster Q3 growth for OpenAI
Ramp economist Ara Kharazian said a closer look at Q3-to-date activity shows OpenAI growing faster than Anthropic in this customer segment. With a month remaining in the quarter, that direction can still change, and Ramp did not disclose the underlying dollar amounts behind the percentages.
Kharazian cited GPT-5.6 Sol as increasingly becoming a developer choice. He also said Anthropic’s Fable 5 had disappointed in adoption and real-world application, citing its price and data-retention requirements imposed by regulators.
Fable is Anthropic’s higher-end model tier and is designed for more targeted uses than a general chatbot. It also drew objections after Anthropic warned Fable users that it must retain their data for 30 days. The result is a more nuanced comparison than a single feature or price point can provide.
Market shares remain a partial measure
Ramp’s data does not represent the entire enterprise AI market. Its customer base spans industries but tilts towards technology, reflecting Ramp’s standing as a Silicon Valley corporate-card provider. The data also excludes large enterprises that use spending-management services from providers such as American Express.
Even so, the figures show that the contest has not settled since Anthropic’s lead among Ramp business customers reported Anthropic’s lead among Ramp business customers, as organisations can switch providers when new models and operating conditions change.
Both companies may still be expanding business revenue as they compete for share. The proportion of Ramp customers paying for AI passed 50% in March and reached nearly 56% in July, indicating continued growth in the overall market.
Business implication
For businesses, the practical implication is to evaluate AI vendors against current developer performance, cost and data-handling requirements, because spending patterns in this segment can move as products and policies change.
