The corporate spend management platform Ramp has updated its AI Index to provide weekly data on token usage and spending across different AI models and providers. This expansion coincides with the launch of a new Token Spend Management product that tracks expenses by user, model, and provider.
Data from over 70,000 U.S. businesses on the Ramp platform shows a 56.1% paid AI adoption rate as of August 2026. This figure significantly exceeds the 22.1% estimate reported by the U.S. Census Bureau for the same period.
Regarding market share among Ramp clients in August 2026, Anthropic led with 43.8%, while OpenAI held 39.8%. The index highlights a wide variance in spending, where the median firm spends approximately $12 per month, while the top 1% of firms spend between $7,200 and $7,450 monthly.
The index also identifies a trend of disciplined spending among high-volume users, with some companies reporting a month-over-month decline in AI expenditure per employee.
