Anthropic overtakes OpenAI in the corporate segment: subscription share among Ramp clients reaches 41%
The corporate AI market is undergoing notable changes. According to my analysis of data from the fintech platform Ramp, in May 2026, Anthropic's share of paid corporate subscriptions among its clients increased by 2.5 percentage points, reaching 41%. At the same time, OpenAI's figure remained virtually unchanged, hovering at 39.5%.
This shift is particularly striking against the backdrop of Anthropic's conflict with the Donald Trump administration. The White House demanded that foreign access to the Mythos 5 and Fable 5 models be cut off, effectively forcing the startup to withdraw its latest developments from the market. Despite this, businesses continue to actively use available Anthropic solutions, primarily the Claude Opus family, confirming their high demand.
The Ramp platform analyzes the spending of over 70,000 companies, making its data representative for assessing corporate preferences. The growth in Anthropic's share indicates that companies prioritize not only novelty but also the stability and effectiveness of already proven models.
My expert assessment: Ramp's data is not just statistics, but a signal of a fundamental shift in the corporate segment. Anthropic has managed to seize the initiative from OpenAI, despite external pressure. This suggests that businesses value reliability and adaptability, not just loud announcements. If the trend continues, OpenAI will have to reconsider its strategy in the corporate sector, otherwise it risks losing its leadership position for good.
