The Brussels think-tank Bruegel published a "First Glance" analysis on Thursday 11 June that put a number on CADA The Commission had not advertised. The Commission's own impact assessment, Bruegel found, costs the migration of public-sector workloads to sovereign-level cloud at up to 86bn euros, on an assumed price premium of just 5% that Bruegel calls unrealistic 1.
That figure dwarfs the rest of the sovereignty budget. The 4.12bn euro AI Gigafactories call due in July and the 2bn euro open-source strategy together come to under a tenth of it.
Bruegel's deeper objection is structural: CADA's test for the highest assurance levels turns on a provider's nationality, not on technical safeguards, and the author argues origin is a poor proxy for security. CADA was adopted on 3 June as the package's cloud law ; the critique lands while the ink is barely dry.
The source matters as much as the sum. This is not US industry lobbying against a Buy-European tilt. It is a centre, Brussels-embedded institution telling The Commission its own figures do not hold.
