OpenAI regains ground against Anthropic in business market, new data reveals

New data from Ramp, a corporate credit card and expense management company, indicates that OpenAI is gaining on Anthropic in the business sector. The data, which covers over 70,000 US businesses, shows that OpenAI has surpassed Anthropic in market share among Ramp’s paying business users. As of July, Anthropic holds nearly 44% of the market, while OpenAI has nearly 40%. This marks a shift from May, when Anthropic had a 41% share compared to OpenAI’s 39%. Ramp economist Ara Kharazian noted that OpenAI is currently growing faster than Anthropic in the third quarter, though the trend could change before the quarter ends. Ramp did not provide actual spending figures, only percentages. The data also suggests that the overall AI market is expanding, with the percentage of Ramp customers using AI services rising from over 50% in March to nearly 56% by July. Kharazian highlighted OpenAI’s new model, GPT-5.6 Sol, as a strong contender for developers, while expressing disappointment with Anthropic’s Fable 5 model, which faced challenges due to data retention requirements. Anthropic’s Fable model, designed for specific use cases, was criticized for its high cost and data retention policy, which sparked controversy among users. Despite the competition, both companies are likely to see growth in business revenue as the market expands.
