European Union
Strategic Autonomy — For economies big enough to cover most layers without leading any: build enough compute, open models and a resilient grid to depend on no single supplier and bargain from strength.
How the Score, Potential and bottleneck cost are worked out: methodology.
The three layers
Energy, grids, data centres and silicon — the physical capacity to run models at scale.
Compute tracked by Epoch AI: the European Union controls 7,100 H100-equivalents, wherever the sites are. Hosted compute is shown, not scored.
Models, alignment capability, standards influence and the talent that produces them.
The capacity to wire AI into the state and the economy while holding public consent.
Where the score comes from
| Layer | Sub-dimension | Basis | Score |
|---|---|---|---|
| Watts | Planning & Permitting | Assessed | 5.8 |
| Firm Power Capacity | Dataset | 8.3 | |
| Sovereign Compute | Dataset | 9.5 | |
| Hardware & Silicon Access | Dataset | 7.5 | |
| Weights | Frontier Model Output | Dataset | 4.2 |
| Alignment Capability | Assessed | 8.6 | |
| Regulatory Standing | Dataset | 8.4 | |
| Talent Density | Assessed | 8.2 | |
| Will | Policy Capacity | Dataset | 7.0 |
| Public Sector Adoption | Assessed | 6.8 | |
| Workforce Transition | Assessed | 7.6 | |
| Public Trust | Assessed | 7.2 |
Assessed marks a measurement we judged rather than took from a dataset: 6 of the 12 here.

These hold the European Union below its Potential. Its two lowest scores cost it the most: frontier model output at 4.2 (part of Weights) and planning & permitting at 5.8 (part of Watts).
Assessment
The European Union operates as a regulatory superpower, shaping global structures through the EU AI Act. While its research baseline is world-class with key nodes in Île-de-France and Munich, it suffers from fragmented venture capital markets and compute clusters spread across independent member states. Its path relies on balancing stringent compliance with sovereign industrial investments.
The art of the possible
The EU's upside is aggregation: gigafactories, JUPITER-class compute, and a single market of 450 million. If InvestAI capital and simplified rules let European champions scale across borders as one market rather than 27, the bloc's collective profile rivals the superpowers.
Strategic play — Strategic Autonomy
Act as one market instead of 27: let InvestAI capital and simpler rules scale champions across borders, pool the gigafactories and JUPITER-class compute, and use regulation, the chokepoint it already holds, to set terms abroad rather than only to slow adoption at home.
Leverage — the nearest position. The one register where the EU is a machinepower in its own right: rules. Firms obey Brussels worldwide because losing the market costs more than compliance. Regulation is the EU's chokepoint, and it has turned it before.
