EU Tech Sovereignty: Reducing Reliance on US Cloud Giants 2026

The European Union is moving from rhetoric to action on tech sovereignty, aiming to reduce its reliance on US hyperscalers like Microsoft, Google, and Amazon for storing critical data. The European Commission is expected to present its Tech Sovereignty Package on May 27, a set of measures designed to bolster the EU's strategic autonomy in sensitive areas.

This shift comes amid growing political instability and recent incidents that highlight US leverage over European tech infrastructure. The package signals a decisive step toward digital independence for Europe.

Why the EU Is Pushing for Tech Sovereignty

The push for tech sovereignty is driven by fears that the US could use its control over technology infrastructure as a geopolitical weapon. Recent events have intensified these concerns. In May, Microsoft reportedly "cancelled" the email account of Karim Khan, a prosecutor cited in a Donald Trump executive order. Microsoft denied the claim, but the damage was done.

Such incidents have raised fears that the US could deploy a "kill switch" against European institutions dependent on American hardware and software. The EU wants to ensure that critical data and services remain accessible regardless of political shifts.

The CLOUD Act: A Legal Backdoor for US Spying

A key driver of the EU's concerns is the CLOUD Act (Clarifying Lawful Overseas Use of Data Act), a 2018 US law that allows US law enforcement to compel tech companies headquartered in the US to hand over data, regardless of where it is stored. This means that even data stored on European servers by US companies could be accessed by US authorities.

The CLOUD Act effectively grants the US government extraterritorial reach over data held by American firms, undermining EU data protection rules like GDPR. For European institutions, this represents a significant risk to data sovereignty.

What the Tech Sovereignty Package Will Include

While details are still emerging, the package is expected to include measures to promote European alternatives to US hyperscalers, incentivize local data storage, and strengthen cybersecurity. It may also involve funding for European cloud providers and standards for secure data sharing.

The goal is to create a more resilient digital infrastructure that can withstand external pressures. This could reshape the European tech landscape and reduce dependency on foreign providers.

Key Takeaways for European Businesses

• Regulatory shift: New rules may require critical sectors to store data within the EU or with trusted providers.
• Increased costs: Migrating to European cloud services could involve short-term expenses but long-term risk reduction.
• Opportunities for EU providers: Local cloud and tech companies may see growth as demand for sovereign solutions rises.
• Compliance complexity: Businesses will need to navigate both EU and US regulations, especially regarding data transfers.
• Geopolitical awareness: Companies must consider political risks when choosing technology partners.

What to Watch Next

The Tech Sovereignty Package is set to be unveiled on May 27, and its specifics will determine how quickly Europe can reduce its reliance on US tech giants. Key points to monitor include funding allocations, enforcement mechanisms, and the response from US companies.
