In May 2026, Anthropic achieved a notable increase in paid corporate subscriptions, rising by 2.5 percentage points to capture 41% of the market among Ramp clients. In contrast, OpenAI's share remained stable at 39.5%, as reported by TechCrunch, which referenced data from the fintech platform.
This uptick in subscriptions for Anthropic occurred amid tensions with the Trump administration, which imposed restrictions on access to its models, Mythos 5 and Fable 5, for foreign users. This regulatory pressure led the startup to withdraw these models from circulation. Despite these challenges, Ramp, which analyzes spending from over 70,000 companies, found that businesses are continuing to leverage Anthropic's models, especially the Claude Opus series.
