The countries that build the most AI are not the ones that use it the most. The 2026 Stanford AI Index counts 59 notable AI models from the United States in 2025 and 35 from China, yet it ranks the United States 24th in generative AI adoption at 28.3 percent, behind the United Arab Emirates at 64 percent and Singapore at 61 percent. Business surveys show a second split: in the European Union, 19.95 percent of enterprises with 10 or more employees used AI in 2025, from 42.03 percent in Denmark to 5.21 percent in Romania.
Key takeaways
- Development and adoption are measured separately: model counts and investment describe builders, while survey shares describe users.
- US private AI investment reached USD 285.9 billion in 2025, more than 23 times China's USD 12.41 billion, which the AI Index says probably understates Chinese spending.
- Eurostat reports 19.95 percent of EU enterprises using AI in 2025, up 6.47 percentage points from 2024.
- Statistics Canada reports 19.2 percent of Canadian businesses using AI in spring 2026, but the survey covers all business sizes and a different period, so it cannot be set against the EU figure directly.
- Large enterprises in the EU used AI at 55.03 percent, small ones at 17 percent, so a country's mix of firm sizes affects its rank.
Who builds AI: models, money, and data centers
The AI Index research chapter lists 59 notable models from the United States and 35 from China for 2025. It adds that China leads in publication volume, citations, and patent grants, while the United States holds higher-impact patents and South Korea leads in AI patents per capita. The summary page gives private investment for 2025 as USD 285.9 billion in the United States, USD 20.92 billion in Europe, and USD 12.41 billion in China, and counts 5,427 data centers in the United States, more than 10 times any other country.
These are measures of supply. A country can sit at the top of them and still have modest everyday use, which is what the next section shows.
Who uses AI: households and firms
The AI Index economy chapter says generative AI adoption varies widely across countries and correlates strongly with GDP per capita. Some countries beat what income would predict, among them Singapore at 61 percent and the United Arab Emirates at 64 percent. The chapter does not name the survey behind these shares, so they are best read as the report's own comparison, not as a census.
For firms, Eurostat runs a harmonized survey. Its 2025 release counts AI use across eight technology types, including text analysis, image recognition, and machine learning for data analysis. The EU average of 19.95 percent hides a wide spread: Denmark 42.03 percent, Finland 37.82 percent, and Sweden 35.04 percent at the top, against Romania 5.21 percent, Poland 8.36 percent, and Bulgaria 8.55 percent at the bottom. Denmark's share rose 14.45 percentage points in a year.
Why the numbers cannot simply be lined up
| Source | Who is counted | Measure | Period | Result |
|---|---|---|---|---|
| Eurostat | EU enterprises with 10 or more employees | Use of any of eight AI technologies | 2025 data | 19.95 percent |
| Statistics Canada | Canadian businesses of all sizes with employees | AI used to produce goods or deliver services | Prior 12 months, spring 2026 | 19.2 percent |
| Stanford AI Index | Countries, generative AI | Adoption share, source not named in the chapter | Report covering 2025 | US 28.3 percent, UAE 64 percent |
The EU and Canadian shares look almost equal, but they cover different firm sizes and different years. Small firms use AI less, so a survey that includes businesses with one to four employees will tend to read lower than one that starts at 10. Statistics Canada samples establishments with employees and reports results by size from one employee upward, with 21,105 sampled and 9,251 responses in 2026.
Size and use shape the rankings
Eurostat splits the EU result by size class. Small enterprises (10 to 49 employees) stood at 17 percent, medium (50 to 249) at 30.36 percent, and large (250 or more) at 55.03 percent. About 83 percent of the surveyed population is small. The most common use among AI-using enterprises was marketing or sales at 34.70 percent, followed by business administration or management at 31.05 percent, and logistics was the least common at 6.08 percent. A country with many large firms or many firms in information services can therefore rank high without a broader culture of use.
Checklist for reading a country comparison
- Does the figure count people, households, or firms?
- Which firm sizes are included, and is there a minimum number of employees?
- What is the reference period, and when was the data collected?
- Was the question about any use or about use in production?
- Is the source an official survey, or a ranking whose method is not stated?
FAQ
Which country is ahead in AI?
It depends on the measure. The AI Index puts the United States first on notable models and investment, China first on publication volume and patent grants, and the UAE and Singapore first on generative AI adoption among the countries it names.
Is Canada ahead of or behind the EU in business AI use?
The published shares are close, 19.2 percent and 19.95 percent, but they come from different surveys with different scopes and dates. The data do not support a ranking.
Why does the US rank 24th in adoption if it builds the most models?
Building and using are different activities. The AI Index notes that adoption tracks income strongly and that some smaller countries exceed their income-based expectation, so a large model industry does not guarantee wide use.
Will the Eurostat figures change?
Yes. The Eurostat page states that data were extracted in December 2025 and that an update is planned for December 2026.
