Key takeaway

Bruegel's Mariniello argues the EU sovereignty package mimics rivals while EU cloud share stays near 15%.

Bruegel economist Mario Mariniello argued in a June publication that Europe's tech-sovereignty package uses nationality as a proxy for security, mimicking the very strategies of the US and China it means to counter. Bruegel is a Brussels economic think-tank, and Mariniello's critique notes that EU cloud providers hold only about 15% of their own home market, so a nationality test does little to change who actually supplies European computing.

Bruegel had already costed the CADA public-sector cloud migration at up to €86bn. The mimicry critique extends that argument: even at that price, a design that screens suppliers by nationality rather than fixing the underlying gaps in energy cost and capital access does not buy genuine sovereignty, only a European-flagged version of the dependency logic it set out to escape.

Deep Analysis

In plain English

Bruegel is a respected economics think-tank based in Brussels. One of its economists, Mario Mariniello, published an argument in June that the EU's new tech-sovereignty rules are not actually making Europe more secure; they are just copying what the US and China do. His argument is based on a simple number: European cloud companies hold only about 15% of their home market. The rest goes to Amazon, Microsoft and Google. Telling government agencies they must use European cloud providers sounds like a sovereignty move, but if European providers do not have the scale to handle the workload, it just makes public services more expensive without making data more secure. Bruegel had already calculated in an earlier report that moving EU public-sector data to EU-only cloud providers would cost up to €86bn. Mariniello's new piece argues the expense does not buy the security benefit it is sold as.

Deep Analysis
Root Causes

Europe's 15% cloud market share reflects a decade of structural disadvantage: US hyperscalers Amazon Web Services, Microsoft Azure and Google Cloud entered the market with capital and network effects that European incumbents could not match at equivalent scale. Deutsche Telekom's Open Telekom Cloud, OVHcloud and Hetzner collectively address different segments and price points but have not closed the hyperscaler gap in the enterprise and public-sector segments CADA targets.

The buy-local mandate, rather than addressing the structural investment gap, attempts to solve a market-share problem through procurement rules. Mariniello's mimicry critique identifies the logical gap: the US and China built market leaders first and restricted access to rivals second; Europe is restricting access to rivals before it has built market leaders.

The restriction without the substitute creates cost without security gain, exactly the €86bn migration premium Bruegel costed in its earlier analysis.

What could happen next?
  • Risk

    If CADA's nationality proxy fails to produce EU cloud market-share gains within five years, the €86bn migration cost will be a permanent structural expense rather than a one-time sovereignty investment.

    Long term · Reported
  • Consequence

    Mariniello's mimicry critique, published by a Commission-adjacent think-tank, provides academic cover for member states seeking to dilute CADA's nationality requirements in trilogue negotiations.

    Short term · Reported
  • Meaning

    The 15% EU cloud market-share figure, cited by Bruegel and sourced from the Commission's own State of the Digital Decade report, is the most authoritative quantification of the structural gap that CADA must overcome to work as intended.

ECIPE found nine states gave about 97% of awarded cloud lots to home providers from 2018 to 2025, and every sovereignty-framed lot went to a domestic supplier. The think tank reads sovereignty clauses as a home-bias tool that narrows competition, with a 46% sole-bidder rate on a small sample.
