What did Bruegel find about EU cloud providers' home market share?

Does CAIDA solve Europe's AI chip dependency problem?

No, according to Bruegel Analysis 13/2026. CAIDA can mandate where European public data lives but says nothing about where the silicon underneath comes from. Both the US and China are building their way out of chip dependency while Europe is legislating around it.Source: ETS Update #7

Background

Bruegel's three-scenario refill model, published 23 April, priced EU storage refill at EUR 26bn at EUR 45/MWh TTF, EUR 35bn at EUR 60/MWh, and EUR 44bn at EUR 75/MWh. With TTF settling at EUR 50.17/MWh on 18 May 2026, the operative scenario has shifted above the EUR 26bn lower-bound towards the EUR 35bn mid-range. More critically, the model assumed the pace required to reach 80% would be delivered; the 17 May AGSI+ print at 0.18 pp/day (against 0.53 pp/day required) means the EUR 26-44bn range is now a cost estimate for a landing below 80%, not at it.

Bruegel publishes the weekly EU gas storage and LNG tracker datasets that underpin Commission and market analysis. Its 13 May weekly dataset confirmed Middle East LNG at its lowest level since 2019. The think tank's joint-buyer Coalition proposal, involving Japan and South Korea in EU LNG procurement, remains the most structurally novel recommendation on the policy table. AccelerateEU (22 April) declined to include any storage injection mechanism, leaving Bruegel's EUR 35bn estimate as the authoritative figure without a policy counterweight. Bruegel's fiscal tracker placed total EU and UK energy crisis spending above EUR 11bn as of May 2026, with Spain accounting for 45%, overwhelmingly through untargeted VAT cuts.

Bruegel is a Brussels-based economic research institution founded in 2005, funded by EU member states, major corporations, and international organisations. Its research spans EU macroeconomic policy, trade, energy economics, and, increasingly, technology sovereignty. Its energy team has been the primary quantitative reference for European gas crisis policy since 2022. In 2026 Bruegel's analytical scope has expanded to cover Europe's structural dependencies on US and Chinese technology infrastructure, making it the leading independent voice on both the cost of energy security and the limits of legislative sovereignty.

Bruegel published Analysis 13/2026 on 19 May 2026, finding that Europe is structurally dependent on US or Chinese computing infrastructure regardless of what the Cloud and AI Development Act (CAIDA) does. Chinese domestic chips power 41 per cent of China's data centres; Huawei projects AI-chip revenue of USD 12bn in 2026, up from USD 7.5bn in 2025. The recommended fix is coordinated EU procurement for compute on the Airbus demand-aggregation model, plus subsidies to move off Nvidia.

In June 2026, Bruegel economist Mario Mariniello deepened the critique: Europe's sovereign tech package uses "nationality as a proxy for security", mimicking the approaches of the US and China without addressing root causes such as energy costs and capital access. With EU cloud providers holding only approximately 15 per cent of their home market, Mariniello argued the package risks replicating the dependency logic it purports to address rather than resolving it.
