Surveys ask people if they use AI. Transaction data shows whether they're paying for it.

That distinction matters. Ramp, the corporate card company, tracks actual spending across more than 50,000 American businesses - including thousands of small businesses - and publishes a monthly AI adoption index based on that real transaction data.

In February 2026, the Ramp AI Index reached a record high: 47.6% of businesses were paying for AI services. That's up from 46.8% in January, and up from roughly 24% a year earlier.

Nearly half of businesses now have AI in their budget. Not just in their conversations. In their budget.

What the Spending Data Tells You

This isn't survey data where someone says "yes, I've used ChatGPT." This is real money leaving real accounts. When a business shows up in the Ramp index, they're paying a monthly subscription to an AI company or processing API charges.

A few things stand out in the latest numbers:

Anthropic's growth is genuinely unusual. Claude adoption grew 4.9% month over month in February - the largest single-month jump for any AI company since Ramp started tracking. Nearly one in four businesses on Ramp now pays for Anthropic. A year ago, it was one in 25. That's a 6x increase in 12 months.

OpenAI is still #1, but losing ground. OpenAI dropped 1.5% in February - the largest single-month decline any AI company has seen in Ramp's tracking. OpenAI is still used by more businesses than any other AI provider, but the direction is changing.

The shift isn't just about performance. Ramp's economist notes something worth paying attention to: when two AI products perform similarly, the cheaper one usually wins in business software. Anthropic is charging more for roughly comparable performance and still winning new customers at a faster rate. That suggests businesses are making choices based on something beyond benchmarks.

Sector adoption is broad. AI adoption growth isn't concentrated in tech companies. Financial services, retail, manufacturing, and food services all showed meaningful growth in early 2026. This is no longer a Silicon Valley thing.

What 47.6% Means for Your Business

If roughly half of businesses are paying for AI, the other half is not - yet.

A few ways to read that:

If you're in the half that isn't paying for AI yet, you're not behind the curve. But the curve is moving. The businesses in your market that adopted AI in 2024 and 2025 have had a year or two to figure out what actually works. Your starting point in 2026 is different from theirs - you have access to better tools, better documentation, and people around you who've already made the early mistakes.

If you're in the half that is paying, the question shifts from "should I use AI" to "am I getting value proportionate to what I'm spending." The Ramp data tracks spending, not results. A subscription that no one on your team actually uses is in the 47.6% - and it's not helping anyone.

The gap between sectors is significant. If you're in retail, manufacturing, or food service - sectors that have historically lagged on tech adoption - the Ramp data suggests your industry is catching up faster than expected. What your competitors are adopting is no longer guesswork.

The Number That Actually Matters for Small Business Owners

The Ramp data also breaks out AI infrastructure spending versus foundation model spending - the companies that build and run the AI models you access through ChatGPT, Claude, and similar tools.

In Q4 2025, businesses spent approximately $430 million on foundation models through Ramp - growing at 126% year over year. That's not startup speculation. That's money changing hands at scale, growing faster than almost any software category in history.

For a small business owner, the takeaway is simple: AI tools are becoming a standard line item in business budgets, the same way website hosting or accounting software did. The question isn't whether to budget for it. It's what you're buying and whether it's working.

If you're spending money on AI tools and don't have a clear answer to that question, start there.
