# Anthropic holds Ramp enterprise payments lead, 43.5% to 39.7%

Ramp data puts Anthropic at 43.5% of enterprise payments to OpenAI's 39.7% in July 2026, with a price war and top-customer concentration in play.

Anthropic took 43.5% of enterprise payments on Ramp's platform in July 2026, to 39.7% for OpenAI, holding the top spot it first won in April 2026 with its coding tool Claude Code, according to Ramp.[^1]

The lead sits under a price offensive. OpenAI cut prices on its existing frontier models by more than 20% in the three months before early August 2026, a move the article says erodes Anthropic's margins.[^2]

Both companies carry the same concentration pattern. The top 1% of customers account for 80% of enterprise revenue for Anthropic and OpenAI alike, Ramp data shows.[^4]

Kyung Hee University's Lee Kyung-jeon, a professor in its big-data applications department, said the $2 trillion valuation reflects a perception of an Anthropic-OpenAI oligopoly, and that the market could keep changing as OpenAI re-emerges and the open-source camp, including Chinese AI, grows.[^3]
