Ramp’s transaction data reveals that OpenAI is dominating enterprise AI budgets, surpassing competitors in the battle for corporate AI investment
As of April, 32.4% of U.S. businesses were paying for subscriptions to OpenAI AI models, platforms, and tools, according to Ramp’s AI Index. This index estimates the business adoption rate of AI products by utilizing Ramp’s card and bill pay data. This represents an increase from 18.9% in January and 28% in March.
Ramp’s data indicates that competitors have encountered significant challenges in achieving comparable advancements. As of the previous month, only 8% of businesses had subscriptions to Anthropic’s products, a decrease from 4.6% in January. In the interim, Google AI subscriptions experienced a decrease from 2.3% in February to 0.1% in April.
In a blog post published on Tuesday, Ramp Economist Ara Kharzian stated that “OpenAI continues to add customers at a faster pace than any other business on Ramp’s platform.” “Our Ramp AI Index indicates that the adoption of OpenAI by businesses is expanding at a faster pace than that of competitor model companies.”

It is important to note that Ramp’s AI Index is not an ideal metric. It examines a subset of corporate expenditure data from approximately 30,000 companies. Moreover, the index is likely to overlook expenditures that are consolidated into other cost centers, as it identifies AI products and services based on merchant names and line-item details.
Nevertheless, the data indicates that OpenAI is bolstering its position in the substantial and expanding enterprise AI market.
OpenAI reported in April that it had surpassed 2 million business users, a significant increase from the 1 million users it had in September. The organization anticipates that enterprise revenue will have a substantial impact on its financial performance. OpenAI anticipates generating $12.7 billion in revenue this year and $29.4 billion in 2026, as reported by Bloomberg.
OpenAI, which does not anticipate becoming cash-flow positive until 2029, is considering charging business customers thousands of dollars for specialized AI “agents” that are intended to assist with software engineering and research tasks.
