Key takeaway

Sovereign cloud spending is tripling, but US hyperscalers and US-built AI models still dominate European infrastructure.

European sovereign cloud spending is forecast to triple from roughly $7bn in 2025 to $23bn by 2027 ¹. All 27 EU member states signed a digital sovereignty declaration in November 2025. European governments describe sovereignty as a "matter of national survival" ².

Budgets are growing, but the harder question is what runs on the infrastructure. AWS, Microsoft, and Google are all members of GAIA-X, Europe's flagship sovereign cloud initiative. The framework that was designed to reduce dependence on American providers now has the Americans inside the tent. GAIA-X's first multi-provider catalogue lists 600 services from 15 providers across four sovereignty tiers ³. Only the highest tier (Label Level 3) excludes companies subject to the US CLOUD Act. Uptake data for Level 3 is not publicly available.

Domestic providers (OVHcloud, Hetzner, Scaleway) account for roughly a sixth of European cloud revenue, with US hyperscalers commanding the rest ⁴. On price, the European alternatives win easily. But the vast majority of AI workloads on European cloud, sovereign or otherwise, use US-built models: OpenAI's GPT-4o, Anthropic's Claude, Google's Gemini. You can run a US model on a German server and call it sovereign. Genuine independence requires sovereignty at both the compute layer and the model layer. Europe has plausible compute alternatives. It has almost no enterprise-scale model alternatives.

Deep Analysis

In plain English

European cloud sovereignty is about who stores and processes your data, and whose laws apply to it. Three American companies; Amazon Web Services, Microsoft Azure, and Google Cloud; together control roughly 70% of the European cloud market. The remaining 30% is split between European companies (OVHcloud, Hetzner, Scaleway, T-Systems) and others. GAIA-X is a European initiative to create a framework for trusted cloud services, with different levels of sovereignty certification. Level 1 is basic compliance; Level 4 means the service is run by a company not subject to US law; which would exclude AWS, Azure, and Google. All 27 EU member states signed a digital sovereignty declaration in November 2025, signalling political commitment to using European cloud services for government data. But current procurement patterns have not changed: the €7 billion Europeans spent on sovereign cloud in 2025 is forecast to triple to €23 billion by 2027, though most of that growth may flow to American companies' European-branded products rather than genuinely European alternatives.

Deep Analysis

Root Causes

European sovereign cloud's persistent 15% market share despite years of policy attention reflects two structural constraints. First, enterprise IT procurement decisions have 5-10 year cloud provider lock-in timelines: organisations that migrated to AWS or Azure between 2015 and 2020 will not complete migration to European alternatives before 2025-2030, regardless of regulatory incentives. The procurement cycle is longer than any regulatory mandate cycle.

Second, GAIA-X's inclusion of US hyperscalers in its catalogue reflects a political compromise that undermines its market differentiation purpose. If AWS and Azure can achieve Level 1 and Level 2 GAIA-X certification by meeting basic data localisation standards, the GAIA-X brand loses its ability to signal European sovereignty to procurement officers.

The catalogue's 600 services from 15 providers includes providers that are CLOUD Act-subject; a structural inconsistency that sophisticated buyers will identify.

What could happen next?

Risk
GAIA-X's inclusion of US hyperscalers in its catalogue at lower sovereignty tiers risks making the GAIA-X brand a market confusion tool rather than a genuine sovereignty signal, undermining EU procurement differentiation.
Short term · 0.75
Opportunity
If EU member states implement mandatory domestic cloud preferences for regulated sectors (following South Korea's model), EU-native cloud providers could gain 10-15 percentage points of regulated-industry market share within 5 years.
Long term · 0.5
Consequence
The $23bn sovereign cloud forecast will disproportionately benefit AWS and Azure European Zone products and French/German hyperscaler sovereignty wrappers, not EU-native independent providers; unless DMA switching cost reductions materialise.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: Japan's attempt to build domestic internet infrastructure in the 1990s through the WIDE Project and domestic ISP ecosystem produced a robust local industry that briefly held significant market share before the global internet's winner-take-most dynamics concentrated hosting and cloud infrastructure in US providers.

Japanese internet sovereignty was real for a decade, then structurally eroded. Europe's GAIA-X faces the same trajectory if it cannot maintain regulatory differentiation that US providers cannot replicate.

Counter-parallel: South Korea's Naver Cloud Platform has maintained approximately 60% domestic market share against AWS and Azure in South Korea, supported by regulatory preferences for domestic cloud in public sector and financial services procurement, and by a domestic technology ecosystem that values local data residency.

If the EU were to implement equivalent mandatory domestic cloud preferences for regulated sectors; rather than voluntary sovereignty tiers; the Korean model suggests genuine market share maintenance is achievable.

The $7bn to $23bn sovereign cloud forecast growth represents a 229% increase in 3 years; roughly 95% compound annual growth rate. This is not market share gain by European providers but rather the rapid monetisation of Europe's existing preference for 'sovereign' framing in procurement. Much of this growth will accrue to AWS and Azure European Zone products and Thales/S3NS (Google Cloud wrapped in French infrastructure), not to EU-native independent providers.

Hetzner's 14.3x and Scaleway's 4.8x cost-performance advantage relative to AWS (per Holori/Callista pricing analysis) is real and measurable, but has not translated into market share gains because switching costs; not running costs; determine enterprise cloud provider selection. DMA interoperability mandates, if implemented, would directly address the switching cost constraint that prevents these price advantages from translating into market share.

Consensus view: Synergy Research Group and IDC both assess the 15% EU-native cloud market share figure as structurally stable over the past five years; it has not grown materially despite GAIA-X, sovereign cloud rhetoric, and national procurement initiatives, because enterprise switching costs and the AWS/Azure ecosystem premium have offset any price or regulatory advantage European providers offer.

The $7bn to $23bn forecast growth is an expansion of overall European cloud spend, not a rebalancing of market share.

Counter-view: OVHcloud CEO Jean-Marc Lazard argues the sovereignty-tier market is growing faster than aggregate figures suggest: the relevant metric is not total cloud market share but share of regulated-industry workloads (financial services, healthcare, public administration, defence) where GDPR and data localisation requirements create genuine preference for EU-native providers.

In that segment, OVHcloud, Hetzner, and T-Systems collectively hold approximately 35-40% of European regulated workload revenue; not 15%.

Key tension: Whether GAIA-X's four sovereignty tiers create a meaningful market segmentation that produces real procurement differentiation, or whether Level 3 and Level 4 (excluding CLOUD Act-subject companies) remain aspirational categories with no substantial uptake among European enterprise buyers.

Sovereign cloud spend set to triple by 2027

The spending surge demonstrates real demand for sovereign cloud infrastructure, but GAIA-X's inclusion of US hyperscalers in its catalogue raises questions about whether the framework delivers genuine independence or sovereignty in name only.

Different Perspectives

European cloud and open-source industry

European cloud providers gain a binding procurement mandate from CADA, confirmed by Gartner's $12.6bn sovereign-cloud figure for 2026. The $40bn Pax Silica commitment signals Brussels will not extend sovereignty discipline to the silicon layer, and the missing €350m Sovereign Tech Fund leaves open-source maintenance infrastructure unfunded beneath those same clouds.

United Kingdom

Science Secretary Kendall's £1.1bn Hardware Plan on 8 June chose demand-side instruments, advancing £150m to British chip startups via the British Business Bank, where Brussels chose supply-side alliance membership. Britain joined Pax Silica before the EU and has no collective EU procurement leverage; the Hardware Plan is the bilateral answer to the same silicon gap.

United States

Pax Silica, a State Department initiative launched in December 2025, secured EU membership the same afternoon Brussels adopted its cloud sovereignty law. Ambassador Puzder had named CADA a red line against the EU-US trade framework; the narrowed CADA scope and the $40bn chip commitment together represent the settlement Washington sought.

France

France was the only EU state to oppose Pax Silica accession at COREPER on 3 June, asking the Commission to clarify the Council's steering role inside the alliance. Paris backed CADA and hosts Mistral AI; a $40bn US-chip commitment contractually narrows the commercial space for the sovereign AI model that France is trying to scale.

European Commission

Von der Leyen framed CADA on 3 June as keeping 'most of our market open to like-minded partners', and the Commission's EVP Virkkunen simultaneously required majority-European ownership for the €4.12bn AI Gigafactories call. Brussels is managing rather than resolving the silicon dependency by asserting regulatory control at the cloud layer while formalising the chip relationship through Pax Silica.

European Central Bank

The ECB's digital euro pilot drew more than 50 PSP applications and is naming 10 to 30 participants in July, advancing on its own monetary mandate without requiring a Commission act. Its trajectory this week is the inverse of CAIDA's: the sovereignty instrument that restricts no US firm is the only one keeping its published calendar.
