Sub-layers

Each sub-layer carries a substitutability weight between 0 and 1: how hard it would be to replace the countries that supply it. A high weight sitting on a concentrated share is what makes a chokepoint.

Sub-layerSubstitutabilityGrade
Rack integration & ODMAssembly of accelerators, memory and networking into finished racks. Taiwan's least-visible and most complete dominance: Foxconn alone takes ~40% of AI rack assembly.0.80B
DC developmentSite acquisition, shell construction and operation of the buildings themselves.0.50C
Colocation & neocloudLeased capacity and GPU-as-a-service. Equinix, Digital Realty and NTT together hold ~30% of colocation revenue.0.45B
Cooling & thermalLiquid cooling, CDUs and heat rejection. Rack power density has turned this from a commodity into a constraint.0.65C
Construction & EPCEngineering and construction delivery, including the skilled electrical trades that are now a live bottleneck.0.35C

Physical: where the assets sit

Ranked by installed data-centre capacity (mw) · 54 countries with a non-zero value

Ranked by installed capacity and operator capex. The US figure is dominated by roughly $725bn of 2026 hyperscaler capital spending.

Control: who could stop you

Ranked by chokepoint score, aggregate (leader = 100) · 9 countries with a non-zero value

Chokepoint leverage. Taiwan leads on rack integration, a dependency that gets a fraction of the attention given to foundry.
