OpenAI Surges Ahead of Anthropic in Corporate AI Spending: Key Insights
OpenAI is showing significant growth compared to Anthropic among U.S. businesses for the current quarter, as revealed by new spending data from Ramp. This marks a noticeable shift since Anthropic previously led in corporate AI expenditures three months ago.
Exclusive Insights from the Ramp AI Index
The data comes from the Ramp AI Index, a comprehensive monthly report that tracks AI adoption and spending across over 70,000 American businesses utilizing Ramp’s corporate card and bill payment platform. Because the index relies on actual transaction data—rather than survey responses—it offers a rare glimpse into the performance of these private AI labs within the enterprise sector.
Recent Trends in AI Subscriptions
The latest complete set of figures, covering July 2026 and released on August 12, 2026, shows Anthropic at 43.5% of U.S. businesses subscribing to its services, an increase of 1.1 percentage points since last month. OpenAI follows closely behind at 39.7%, with a more modest rise of 0.23 points. This marks a significant lead for Anthropic, which had been expanding its dominance through July 2026.
OpenAI’s Rapid Growth in Q3
However, Kharazian notes a shift in momentum for Q3, with OpenAI outpacing Anthropic among Ramp’s business users. He attributes this to OpenAI’s newly released flagship model, stating, “GPT-5.6 Sol is proving to be a favorite among developers.” In contrast, he mentions that Anthropic’s Fable 5 model has not met expectations in terms of adoption, influenced by pricing and stringent data retention regulations.
Performance Insights from July’s Data
The August update from Ramp sheds light on these dynamics. Fable 5, launched in July 2026, accounted for just 6% of token purchases by businesses and 11.4% of total spending on Anthropic models—despite being the most expensive option at approximately $10 per million tokens. In comparison, OpenAI’s GPT-5.6 Sol commanded a more substantial 25% share of its token sales and 23% of overall spending at half the cost. Fable 5’s spending was about 75% that of GPT-5.6 Sol in its first month, highlighting its slower market uptake.
A Thriving Market Landscape
The competition is intensifying within a growing market. The Ramp AI Index indicates that overall AI adoption among businesses has reached 55.7%, a rise from just over 50% in March 2026, with spending per customer increasing across all tiers. In July, the average AI-spending business allocated $11.95 per employee monthly, while the top 10% spent $650 and the most elite 1% spent a median of $7,400. AI expenditures on Ramp’s platform have quadrupled over the past year.
Emerging Trends in AI Spending
An additional trend to watch is the growing preference for open-source models. In July, 6.1% of AI-spending businesses utilized model-serving platforms, up from 4.5% in January 2026. Kharazian points out that while first-time AI users predominantly favor American labs, established businesses are increasingly exploring open-source alternatives.
Understanding Ramp’s Data Limitations
It’s crucial to note the limitations of the Ramp AI Index. The sample leans towards the tech industry, reflecting Ramp’s customer demographics, and excludes larger companies that utilize other expense management services. The index only accounts for paid transactions, meaning organizations using free AI tiers are not represented, suggesting actual adoption rates may be higher. Ramp provides percentage data rather than dollar amounts, and the model-level statistics come from a select group of customers engaged with its token spending management product, which likely skews towards the tech sector.
Looking Ahead: Q3 Growth Insights
As we approach the end of the quarter, the growth figures offer a snapshot rather than a concluding judgment. The upcoming Ramp AI Index update, covering August 2026 spending, will reveal whether OpenAI can reclaim its position after losing ground in the spring.
