Large firms use AI much more often
OECD · OECD Publishing · 5 Nov 2026
Source finding
The OECD reports about 20 percent AI use across firms and 52 percent among large firms for 2025. The overall group generally covers firms with at least ten employees, large firms at least 250.
Our interpretation
A usage rate does not establish productivity gains. Check the business’s own data, skills and technical prerequisites rather than chasing a headline benchmark.
Method and evidence
OECD international statistical report published on 5 November 2026. Chapter 3 draws on national business surveys and the OECD ICT usage database. Figure 3.1 uses 2025 or the latest available year. Strong descriptive orientation, not an impact test.
Limitations and interests
Countries differ in survey year and coverage; Switzerland includes firms with five or more employees. No single combined sample size. The separate 2025 country comparison fills gaps with model estimates; future paths are projections. The OECD is an economic policy organisation, not an AI vendor.
What businesses can do
Before the next AI project, check whether suitable data, skills and technical integration are available. Then measure benefits in the specific workflow.
Where to start
