Key Takeaways

  • The EU remains dependent on non-EU countries for more than 80% of its digital products, services, infrastructure, and intellectual property.
  • Investment projections point to substantial funding gaps in data centers, mobile networks, chips, cloud computing, and artificial intelligence.
  • ASML, OVHcloud, and SiPearl illustrate Europe’s technical strengths, but fragmented capital and procurement could limit their ability to scale.

Europe’s digital-sovereignty campaign is entering a more capital-intensive phase. After years spent developing regulations, industrial policies, cybersecurity requirements, and strategic targets, the European Union is confronting a harder question: who will finance the infrastructure needed to turn those ambitions into operating capacity?

The exposure is considerable. The EU relies on non-EU countries for more than 80% of its digital products, services, infrastructure, and intellectual property, according to a European Parliament estimate reported by El País. That reliance spans cloud computing, advanced semiconductors, artificial intelligence systems, and networking equipment.

Dependence does not automatically mean vulnerability. Global supply chains can lower costs and accelerate innovation. But concentrated reliance becomes more consequential when trade restrictions, geopolitical tensions, foreign laws, or capacity shortages affect access to critical technology.

Money is the immediate constraint. EU research and development spending reached €381.4 billion in 2025, equivalent to 2.22% of GDP. The European Commission estimated that this remained 34% below combined US and Chinese investment.

Member States have committed €288.6 billion across 1,910 digital measures. Yet high-tech digital innovation may require between €212 billion and €380 billion every year, according to the European Parliamentary Research Service. Comparing a multi-program commitment with an annual investment requirement is not perfectly like-for-like, but it captures the scale mismatch confronting policymakers.

Digital sovereignty is not a single market that can be funded through one program. It covers semiconductor fabrication and equipment, sovereign cloud environments, AI compute, high-performance computing, data centers, fiber, mobile networks, cybersecurity, and workforce development. Each area has different economics, development cycles, and risk profiles.

Data-center capacity provides a particularly stark example. The European Central Bank estimates that Europe may need up to €600 billion over the next decade to close its capacity gap, including investment in chips. The projected shortage rises from 3 GW in 2025 to roughly 20 GW by 2036.

Connectivity presents another gap. Europe is forecast to require €475 billion in mobile-network investment by 2035, while approximately €270 billion is expected under current conditions. That leaves a potential €205 billion shortfall. Without sufficient network capacity, investment in AI services and cloud infrastructure may deliver less economic value than expected.

Europe is not starting from scratch. ASML occupies a strategically important position in semiconductor equipment. OVHcloud offers a European cloud alternative for organizations concerned about data location, legal jurisdiction, and supplier concentration. SiPearl is developing processors for sovereign high-performance computing. These companies show that Europe retains deep technical capability in selected layers of the digital stack.

The problem is scale, and occasionally patience. Semiconductor facilities and data centers require large upfront commitments, long planning horizons, dependable energy supplies, and customers prepared to purchase capacity over time. European capital markets remain fragmented, while national procurement policies can divide demand, making it difficult for European providers to achieve global scale.

Policy frameworks provide direction. The European Chips Act, adopted in 2023, seeks to strengthen semiconductor research, production, and supply-chain resilience. The EU Digital Decade 2030 targets cover connectivity, digital skills, business adoption, and public services. The European Commission has also positioned digital capacity as part of Europe’s wider economic and strategic agenda.

Still, targets do not finance infrastructure by themselves. Brussels and Member States may need to combine public guarantees, cross-border procurement, institutional capital, and regulatory changes that make long-term technology projects more investable. Public funding can absorb early risk, but private capital will probably carry much of the eventual burden.

The debate also extends beyond industrial competitiveness. The Atlantic Council has connected digital sovereignty with Europe’s ability to operate democratic institutions and public digital services under its own legal principles. That said, sovereignty does not require technological isolation. A more practical objective is credible choice: European customers should have viable suppliers, interoperable systems, and enough domestic capacity to avoid dependence on any single foreign ecosystem.

For business technology leaders, the shift could influence cloud procurement, data architecture, network planning, and vendor selection. The next phase will be judged less by the number of initiatives announced in Brussels and more by whether Europe can concentrate capital, aggregate demand, and give companies such as ASML, OVHcloud, and SiPearl room to scale.
