Large firms (250 or more employees) are 1.4 to 3.2 times as likely to use AI as small firms, a gap of 13 to 38 percentage points in 2025 to 2026 official statistics. In the US the gap starts only at about 50 employees: firms with 1 to 49 employees all sit at 21 to 25 percent. 13–38 pts more AI use in large firms than small ones; large firms are 1.4 to 3.2 times as likely - High confidence - 4 primary sources - 2025 to 2026 - Last checked October 14, 2026 ## Cite this EVY (2026).

Size bands differ too, and Canada compares 100+ firms rather than 250+, so its gap sits below the range. All are firm counts, so the many very small firms dominate national averages. The gap is widest for advanced uses such as generating text or code. ## Every study on one scale Shaded: 13–38 points One figure A range in one study Chart values as text - Scale: points gap, large against small firms. Shaded range: 13–38 points. - US Census (2026): about 13 points (36.5% against about 23%) - ONS, UK (2026): 15–22 points - Eurostat, EU (2025): 38 points (17% against 55%) - Statistics Canada (2026): 8 points (100+ against 1 to 4) **Why high confidence:** Four official statistics agencies and an OECD random survey all find adoption rising with firm size. The direction is settled; the size of the gap depends on how each survey defines AI, its time window and its size bands. ## Sources Sources for F-30 | Study | Creator | Year | Sample | Method | Figure | Link | | --- | --- | --- | --- | --- | --- | --- | | Business Trends and Outlook Survey (BTOS), employment size class estimates | US Census Bureau | 2026 | About 20,000 responses per two-week period; collection ending 4 October 2026 | Official experimental survey; AI in any business function in the prior two weeks.

Barely, in the US. Firms with 1 to 4 employees (23.9%), 5 to 9 (21.5%), 10 to 19 (22.4%) and 20 to 49 (24.8%) all use AI at about the same rate; the step up comes at 50 employees (29.2%) and 100 (36.4%). Within the OECD's seven-country survey, one-person companies use generative AI half as often as firms with 50 to 249 employees (23.6% against 45.8%). Small adopters may use it more intensively: in the UK, 17% of AI-using firms under 10 employees use it extensively, against 9% of firms with 250 or more. ## Numbers you may have seen These figures circulate widely. Here is what the original source says. - **Firms with at least 20 employees are the biggest AI users (US Census).** The headline is about a trend from December 2025 to May 2026. In the latest data, firms with 20 to 49 employees (24.8%) sit close to firms with 1 to 4 (23.9%); the step up comes at 50. - **35% of UK businesses use AI.** That covers businesses with 10 or more employees in June 2026. Including the smallest firms, it was 29% in June and 30% in September 2026. - **Large companies are twice as likely to use AI as SMEs.** Roughly right but band-dependent. In 2025 to 2026 data the ratio runs from about 1.4 (US, Canada) to 3.2 (EU, 250+ against 10 to 49). ## More from Small Teams - [F-28**96–99%**How much of the economy do small companies make up?](https://evy.so/facts/small-companies-share-of-economy/) - [F-29**20–46%**What share of small businesses use AI, and for what?](https://evy.so/facts/small-businesses-using-ai/) - [F-31**54–63%**What stops small companies from adopting AI?](https://evy.so/facts/what-stops-small-companies-adopting-ai/) - [F-32**65–78%**Do small firms that use AI see gains?](https://evy.so/facts/small-firms-gains-from-ai/) - [F-33**45–52 h**How many hours do small business owners work, and how much goes to admin?](https://evy.so/facts/small-business-owner-hours/) [The whole chapter](https://evy.so/facts/small-teams/) · [Chapter poster](https://evy.so/facts/small-teams/sheet/) · [All of The AI at Work Fact Book](https://evy.so/facts/)
