Business adoption of artificial intelligence varies by more than a factor of two across US states, with Colorado leading at 23.2 percent of businesses using AI on average in 2026 and West Virginia trailing at 10.8 percent.

Arizona follows Colorado at 22.9 percent, with Washington, D.C. at 22.5 percent. Oregon and Utah tie for fourth at 21.1 percent. The national average sits at 18.2 percent. California, frequently assumed to lead given its concentration of AI developers, ranks 13th at 19.5 percent, above the national figure and well behind the top tier.

The geographic spread is smaller than the spread by company size. The gap between large and small firms exceeds the 12.4 point gap separating Colorado from West Virginia. Larger organizations carry the internal IT staffing, established vendor relationships, and documented workflows that make piloting and scaling AI a manageable project. Smaller firms face higher effective cost per seat and typically access AI through whatever capability arrives bundled in software they already license.

That size effect suggests state-level rankings partly reflect the industry and firm size composition of each state economy rather than differences in willingness to adopt. States with concentrations of large professional services, technology, and finance employers post higher averages regardless of local policy or infrastructure.
