8.1Compute hardware and fabrication
AI compute is built from advanced logic and memory chips made in a few clusters. Market figures are strong; counts of chips and capacity by place are thin.
| Component | State | Evidence | Status |
|---|---|---|---|
| Logic and memory | logic USD 301.9 billion and memory USD 223.1 billion of sales in 2025 | 8 | Reported |
| AI supercomputers | performance doubling about every nine months; one 2025 system used about 200,000 chips | 1 | Reported |
| Foundry concentration | press reports give the largest foundry nearly 70% of 2025 foundry sales; about 74% of its wafer revenue came from 7 nanometre and smaller nodes | 222728 | Reported |
| Vendor products | one vendor lists 208 billion transistors per accelerator on a custom 4NP process; a vendor claim | 19 | Reported |
Couplings
- INF ↔ FIN sales and plants
- AIC → INF demand
- TRD → INF controls
Evidence to bind in 2027
- chip and accelerator volumes by type
- fabrication capacity by country

8.2Energy, power and water
Compute and fabrication need electricity and cooling water. US data centre use is documented; plant water use is reported by single companies.
| Component | State | Evidence | Status |
|---|---|---|---|
| Data centre electricity | US use 176 TWh in 2023, about 4.4% of national electricity | 1516 | Reported |
| Global data centre electricity | about 415 TWh in 2024 and about 945 TWh in 2030 in the IEA base case, from search summaries | 24 | Reported |
| Efficiency | hardware efficiency rose about 40% a year; sparse models can use under a tenth of the energy of dense ones | 57 | Reported |
| Fab water | one company reports about 5,300 acre-feet a year for one fab and a 65% reclamation rate | 23 | Reported |
Couplings
- AIC → ENE load growth
- ENE ↔ WAT cooling and process water
- ENE → CLI emissions
Evidence to bind in 2027

8.3Equipment, memory and materials
Chips depend on specialised tools, memory stacks and minerals. Equipment billings are documented through a trade report; materials figures are not bound.
| Component | State | Evidence | Status |
|---|---|---|---|
| Equipment billings | USD 135.1 billion in 2025, up 15%; North America down 20% and Europe down 41% | 9 | Reported |
| Lithography | Moore observed doubling in 1965 and revised the pace in 1975; the equipment maker states EUV gives the highest resolution | 2036 | Reported |
| Memory | a high-bandwidth memory standard was published in 2025; details come from search summaries | 32 | Reported |
| Minor minerals | gallium and germanium are used in chips and concentrated in primary production; primary figures not bound | 252640 | Inferred |
Couplings
- TRD → INF tools and controls
- MIN → INF materials

8.4Economy, investment and workforce
Sales and public programmes are large and well documented. Outlays and workforce numbers are the thin parts of the evidence.
| Component | State | Evidence | Status |
|---|---|---|---|
| Sales | USD 791.7 billion in 2025; about USD 1 trillion projected for 2026 by SIA | 8 | Reported |
| US programmes | USD 39 billion for manufacturing and USD 11 billion for research; award outlays not bound at the close | 4411 | Reported |
| EU programmes | more than EUR 33 billion across 19 State aid decisions; second act proposed June 2026 | 12 | Reported |
| Japan and India | Rapidus round of JPY 267.6 billion in 2026; India mission listed | 214243 | Reported |
Couplings
- FIN → INF plants and tools
- GOV → FIN subsidy flows
- HLT → INF workforce
Evidence to bind in 2027

8.5Security, export controls and governance watch
Export controls and subsidies now shape the supply chain. Rules change at short notice, so the watch follows the rule texts.
| Component | State | Evidence | Status |
|---|---|---|---|
| US controls | licence required for advanced computing items to entities headquartered in Country Group D:5; Section 232 investigation listed | 13 | Reported |
| Diffusion rule | framework published in January 2025 and rescinded in May 2025, per law-firm summaries | 3031 | Reported |
| Allied controls | Netherlands and Japan control lithography equipment, cited from memory | 41 | Inferred |
| EU governance | three pillars and a European Semiconductor Board; second act proposed | 1233 | Reported |
Couplings
- TRD → INF controls
- GOV → FIN subsidy flows
