Just 1% of Ramp's business customers account for 80% of all enterprise spending on OpenAI and Anthropic, the corporate card company reported this week. [^1]

The finding is drawn from transaction data covering more than 70,000 US businesses. [^2]

Ramp lead economist Ara Kharazian stated this concentration is greater than any other software category the firm tracks. [^3]

Separate data from YipitData shows concentration at Anthropic specifically has risen sharply. The company's top 1% of customers generated 46% of its revenue in August 2026, up from 25% one year prior. [^4]

Kharazian also noted that this dynamic has given enterprise buyers leverage. OpenAI and Anthropic are offering customer discounts rather than locking in guaranteed high spend levels in contracts. [^5]

This suggests very few businesses are currently committing meaningful budget to commercial AI tools.
