European Union cloud sovereignty efforts have hit a major roadblock: a new study estimates that reducing reliance on US cloud providers could cost €115 billion over ten years. The figure, from the European Centre for International Political Economy (ECIPE), comes as Brussels advances its Cloud and AI Development Act (CADA), proposed in June 2026.
The debate matters because three US tech giants—Amazon Web Services (AWS), Microsoft Azure, and Google Cloud—control over 70% of the European cloud market, according to the European Commission. That concentration has raised concerns about data control and strategic autonomy.
Why Cloud Sovereignty Is Back on the Agenda
Cloud sovereignty is the idea that European governments and businesses should not depend on foreign providers for critical digital infrastructure. The concern is practical: a public administration running applications on a US cloud could be affected by decisions made outside Europe.
For companies, the risk is similar. Building core systems on a single foreign provider can create lock-in and expose them to policy shifts they cannot influence. The European Commission has flagged this dependency as a strategic vulnerability.
The €115 Billion Price Tag
The ECIPE study, funded by CCIA Europe—a trade association whose members include Amazon, Google, and Meta—puts a hard number on the shift. It estimates that moving away from US cloud providers would cost €115 billion over a decade.
The study's author states that the conclusions are independent of the funding organization. Still, the involvement of CCIA Europe is likely to fuel debate about the study's framing, given that its members are among the market leaders that would be most affected.
What the Cloud and AI Development Act Proposes
The Cloud and AI Development Act (CADA) is the EU's legislative response to cloud dependency. While details are still emerging, the act aims to bolster European cloud capacity and reduce reliance on non-EU providers.
The proposal comes amid broader EU efforts to strengthen digital sovereignty, including initiatives on data sharing and AI development. But the cost estimate adds a new dimension to the discussion: how much are European taxpayers and businesses willing to pay for independence?
Key Takeaways
- ECIPE study estimates €115 billion cost over 10 years to reduce US cloud reliance.
- AWS, Microsoft Azure, and Google Cloud hold over 70% of the European cloud market.
- The Cloud and AI Development Act (CADA) is the EU's proposed legislative response.
- The study was funded by CCIA Europe, whose members include Amazon, Google, and Meta.
- Debate centers on the trade-off between strategic autonomy and economic cost.
Market Concentration and Its Implications
The European Commission's finding that three US providers dominate the market underscores the challenge. Any push for sovereignty would require building alternative capacity, which takes time and investment.
European cloud providers exist, but scaling them to compete with AWS, Azure, and Google Cloud is a massive undertaking. The €115 billion figure suggests the transition would not be cheap—and raises questions about who would bear the cost.
| Provider | Market Share (Europe) | Headquarters |
|---|---|---|
| Amazon Web Services (AWS) | Part of >70% combined | United States |
| Microsoft Azure | Part of >70% combined | United States |
| Google Cloud | Part of >70% combined | United States |
| European providers | Remaining <30% combined | Europe |
Who Pays and Who Benefits
The cost estimate is likely to become a political football. Supporters of sovereignty argue that the price of dependence could be higher in the long run, especially if foreign providers are subject to conflicting legal obligations.
Critics, including those aligned with US tech firms, will point to the €115 billion figure as evidence that the push is economically risky. The study's funding by CCIA Europe will be used to question its neutrality, even as the author asserts independence.

For European businesses, the outcome matters directly. New rules could force them to re-evaluate cloud contracts, potentially increasing costs or limiting access to advanced services. Smaller companies may find it harder to absorb the transition. The background to this story is set out in Business: latest articles.

What to Watch Next
The CADA proposal will now go through the EU legislative process, where the cost estimate is likely to be heavily debated.
