Editorial correction — 2026-09-22: unsupported valuation and forecast claims were withdrawn. The replacement below keeps dated evidence separate from hypothetical arithmetic.
Keep the correction visible
Editorial correction — 2026-09-22. Earlier market-size and job-growth assertions lacked a specific supporting dataset and were removed. The present source review does not turn earlier observations into results for the unfinished 2026 calendar year.
Three measures that answer different questions
Stanford’s 2026 Economy chapter reports that corporate AI investment more than doubled in 2025 and puts adoption at 88% of surveyed organisations. Investment is not sales, and surveyed adoption is not the share of every business using AI productively. The IEA’s energy outlook addresses data-centre electricity demand and forecasts; it cannot be added to financial investment to create a market size.
| Measure | Boundary to preserve |
|---|---|
| Investment | Currency, year, financing categories and possible double counting |
| Adoption | Sample, geography, question and meaning of uses AI |
| Electricity | Energy rather than connection power; data centres rather than AI alone |
| Forecast | Scenario, future year and uncertainty; not an observed result |
Power is not annual electricity
A fictional facility drawing 100 MW constantly for a non-leap year uses 100 × 8,760 = 876,000 MWh, or 0.876 TWh. If 100 MW is only its approved connection capacity, actual annual consumption remains unknown without operating data. At an assumed constant 50% utilisation, the arithmetic becomes 0.438 TWh. These are hypothetical calculations, not a facility measurement or forecast.
An evidence sheet for your presentation
- Copy the exact claim you want to make.
- Record the metric, unit, observation period and publication date separately.
- Identify the population or activities included and excluded.
- Mark measured, estimated, surveyed and projected values.
- Keep the exact source section and state what decision the claim informs.
For a product team, accepted tasks, support burden and cost per useful result may be better measurements to collect. A global investment figure does not establish those outcomes. If a number cannot be tied to the claim’s scope, remove it from the presentation rather than rounding it into a more confident headline.
Sources and scope
- Stanford AI Index 2026, Economy — Reports 2025 investment and surveyed organisational adoption; not a census or proof of return on investment.
- IEA, Key Questions on Energy and AI, 2026 executive summary — Describes data-centre demand and conditional future demand; not solely AI or a local tariff.
