**What happened:** Ramp, the corporate card and spend-management firm, says Anthropic still leads OpenAI among the 70,000-plus US businesses it tracks, but OpenAI is closing in.

**The numbers:** Anthropic took the lead in May 2026 with 41% of businesses versus OpenAI's 39%. By July, Anthropic had grown to nearly 44%, but OpenAI had climbed to nearly 40%, its share rising again after May.

**The context:** Overall AI adoption among Ramp's customers is surging. The share paying for AI passed 50% in March and hit nearly 56% by July, according to the [Ramp AI Index](https://techcrunch.com/2026/08/20/openai-is-gaining-on-anthropic-with-business-users-new-data-indicates/).

**The catch:** Anthropic's premium model, Fable 5, has captured a smaller slice of usage than OpenAI's cheaper GPT-5.6 Sol. That suggests businesses are reluctant to pay extra for small performance gains.

**In their words:** Ramp economist Ara Kharazian said "GPT-5.6 Sol is really good, increasingly the choice for developers."

**Who's affected:** Developers are the swing group. Their preference for GPT-5.6 Sol is a big driver of OpenAI's renewed momentum.

**Why it matters:** Anthropic reported a $65 billion run rate in July against OpenAI's roughly $40 billion, so Anthropic still leads on revenue. But the Ramp figures show the enterprise adoption race is tight, and price-performance, not raw capability, is what's deciding it.

**What's next:** Watch whether Anthropic responds on pricing, or whether OpenAI's cheaper model keeps eating into business share through the rest of 2026.

## Key takeaways

- Anthropic's business share hit 44% in July, OpenAI's 40%
- Cheaper GPT-5.6 Sol is winning over developers
- Overall AI adoption among Ramp customers reached 56%
