OpenAI finds a crack in Anthropic's business AI lead
Although OpenAI trails Anthropic in business adoption, it won a moneymaking battle in July with its most advanced model, GPT-5.6 Sol.
Anthropic retains its lead in business adoption over OpenAI, according to Ramp's July AI Index. While OpenAI's GPT-5.6 Sol model was more popular than Anthropic's Fable 5 AI model in July, the pricing advantage of OpenAI's cheaper GPT-5.6 Sol model threatens Anthropic's top model. Despite a rocky start for Fable, including temporary shutdowns and pricing adjustments, Anthropic still enjoys a larger share of business adoption, with 43.5% of US businesses paying for Anthropic AI products in July compared to 39.7% for OpenAI.
The popularity of AI agents has driven much of the industry's revenue growth, with the top 1% of AI spenders paying a median of $7,400 per employee for AI tools in July, up from less than $5,000 in June.
