In May 2026, Anthropic's share of paid corporate subscriptions among Ramp clients increased by 2.5 percentage points to 41%. OpenAI's share remained nearly unchanged at 39.5%, according to TechCrunch, citing data from the fintech platform.
This growth coincided with Anthropic's conflict with the Trump administration. The White House demanded that access to Mythos 5 and Fable 5 be restricted for foreigners, effectively forcing the startup to withdraw its latest models from the market. Ramp analyzes spending from over 70,000 companies and noted that businesses continue to actively utilize Anthropic's available models, particularly the Claude Opus family.
