Ramp released new spending data showing OpenAI is growing faster than Anthropic among U.S. business users so far in the third quarter, narrowing a gap that has widened since Anthropic overtook OpenAI in market share this past May.

As of July, 43.5% of the more than 70,000 U.S. businesses tracked by Ramp paid for Anthropic subscriptions or tokens, up 1.1 percentage points from the prior month. OpenAI reached 39.7%, gaining only 0.23 percentage points over the same period. But Ramp economist Ara Kharazian said OpenAI has been expanding at a faster rate than Anthropic in Q3 to date, according to TechCrunch.

"GPT-5.6 Sol is really good, increasingly the choice for developers," Kharazian posted on X $TWTR. "Fable 5, meanwhile, disappointed both in adoption and real-world application given price plus data retention requirements imposed by regulators," he said.
