Key Takeaways
- The Scale. The European Parliament cited reliance on non-EU providers for over 80% of digital infrastructure when formally calling for a “Eurostack” — a sovereign alternative across chips, cloud, software, and AI.
- France Moves First. France is transitioning 2.5 million civil servants from Microsoft Teams and Zoom to Visio — a domestically built sovereign platform — by 2027.
- The Trump Catalyst. The prospect of a US executive order restricting digital services to European users — already legally plausible under existing executive authority — has transformed European digital sovereignty from a policy aspiration to a security imperative.
- What Is Being Built. Mistral for AI, STACKIT and OVH for cloud, Wero for payments, Visio for communications — the Eurostack is no longer theoretical. It is being deployed.
Introduction: From Rhetoric to Procurement Policy
For years, “European digital sovereignty” was a phrase used at conferences. It was aspirational — a description of where Europe wanted to be, not where it was. The gap between the aspiration and the reality was embarrassing: European governments ran on AWS. European civil servants communicated on Microsoft Teams. European companies stored their data on Google Cloud. European AI research ran through OpenAI APIs.
In 2026, something shifted. The combination of Trump’s return to office, the weaponisation of trade policy, and the visible risk that critical US digital services could be restricted or modified for geopolitical purposes has converted European digital sovereignty from a conference topic into procurement policy.
The Eurostack project — Europe’s attempt to build a sovereign digital infrastructure layer spanning chips, cloud, AI, payments, and communications — is being actively deployed. It is not ready to replace US infrastructure entirely. It may not be ready for another decade. But the direction is no longer ambiguous, and the pace is accelerating.
Direct Answer: What is the European Eurostack and why is it being built now? The Eurostack is a coordinated European effort to build sovereign alternatives to US-dominated digital infrastructure — including cloud computing, AI models, payments, communications, and eventually chips. It is being built now because the combination of Trump-era trade aggression, the potential for US executive orders restricting digital services to foreign users, and growing European consensus on the security risks of dependency has made action politically viable. The European Parliament formally endorsed the Eurostack in January 2026, citing over 80% reliance on non-EU providers for critical digital infrastructure.
The Dependency Problem: What Europe Actually Relies On
The 80% figure cited by the European Parliament covers the full stack of digital infrastructure:
Cloud computing: AWS, Azure, and Google Cloud collectively dominate European cloud spending. European alternatives exist — OVH, Hetzner, Ionos — but at a fraction of the scale and with significant capability gaps in AI-specific infrastructure.
Office and communications: Microsoft 365 and Teams, Google Workspace, Zoom, and Salesforce are deeply embedded in European enterprise and government. The switching cost for large organisations is measured in years of migration work and billions in retraining.
AI models: The frontier AI models powering European enterprise workflows — ChatGPT, Claude, Gemini — are all US-developed, US-hosted, and subject to US export controls, US government access requests, and US terms of service. The only significant European exception is Mistral.
Payments: Visa and Mastercard dominate European card transactions. Most payments route through US-controlled networks despite the EU having its own Single Euro Payments Area (SEPA) infrastructure.
Operating systems and browsers: Windows, Chrome, iOS, and Android account for effectively all European consumer devices.
The dependency is not theoretical. European governments have already experienced its consequences. During COVID, EU digital infrastructure decisions were constrained by protocols from US platform providers. EU health contact-tracing apps had to conform to Apple and Google’s API specifications. European institutions could not modify those specifications unilaterally.
The Trump Catalyst
Two events in 2025–2026 transformed European urgency from moderate to acute.
Executive Order Powers. Legal analysis published by the European Council on Foreign Relations in late 2025 concluded that a scenario where a US president issues an executive order restricting US digital services to European users is “plausible” under current US law. The scenario is described as a potential “digital Liberation Day 2.0” — analogous to the trade tariff shock but applied to digital infrastructure. The paper describes the European position: “If high-value data is being stored now by US providers, and if a US executive order restricted access to that data, European institutions would have no remedy under US law.”
White House Technology Memorandum. In February 2025, the White House issued a memorandum calling for tariffs and other responses in cases where foreign governments impose “discriminatory” digital regulations — explicitly targeting EU digital policies including the GDPR and the Digital Markets Act. The memorandum treats European digital regulation as an attack on US companies and signals willingness to use trade tools in response.
For European policymakers, these developments made a clear point: digital dependency is not just an economic issue. It is a security vulnerability with an identifiable adversary. The fact that the adversary is a nominal ally makes it more uncomfortable, not less.
What Is Actually Being Built
Cloud: OVH and STACKIT
OVH is Europe’s largest independent cloud provider, operating data centres exclusively in Europe under European law. STACKIT, operated by Schwarz Group (the company behind Lidl and Kaufland), offers enterprise cloud from European data centres with full GDPR compliance and explicit commitments to data localisation.
Neither matches AWS or Azure in the breadth of managed services. Both are adequate for the majority of standard enterprise workloads. For AI-specific infrastructure — GPU clusters, model training, inference at scale — European alternatives lag significantly behind.
AI: Mistral
Mistral is the most significant European AI story of the past 18 months. The Paris-based company, backed by €1.3 billion from ASML, patient public capital, and French research networks, has shipped models competitive with US frontier offerings at a fraction of the size and cost.
Mistral Small 4 — released March 16, 2026 — is a 119 billion parameter hybrid model with 6.5 billion active parameters and a 256,000 token context window. It runs efficiently on European hardware. It can be self-hosted. It is open-weight, meaning European organisations can run it on their own infrastructure with no dependency on Mistral’s servers or Mistral’s continued operation.
Mistral is not GPT-5. But for the majority of enterprise AI use cases — document analysis, code generation, customer service, data extraction — it is adequate and sovereign.
Payments: Wero and the EuroPA Alliance
In early 2026, the European Payments Initiative (EPI) and the EuroPA Alliance signed a memorandum to create a pan-European interoperable payment network centred on Wero — a digital wallet currently used by approximately 130 million users across 13 European countries. Cross-border payments are rolling out in 2026, with e-commerce integration planned for 2027.
The long-term vision is the digital euro, expected by 2029, which would eliminate European dependence on Visa, Mastercard, and US-controlled payment infrastructure entirely.
Communications: Visio and LaSuite
France’s LaSuite (Suite Numérique) is the most advanced national digital sovereignty programme in Europe. It includes Visio — a sovereign video conferencing platform built to replace Microsoft Teams, Zoom, and Webex for French government use. The transition covers 2.5 million French civil servants by 2027.
Visio is already in testing with approximately 40,000 users. It ensures GDPR compliance and data residency within French jurisdiction. Similar programmes are in development in Germany and the Netherlands.
The Legislative Framework
The EU is backing the Eurostack with legislation designed to create procurement incentives and reduce regulatory barriers for European digital providers:
Cloud and AI Development Act (CADA): A Q1 2026 legislative proposal aimed at bolstering Europe’s capacity to develop, deploy, and scale cloud and AI. Expected to include EU-wide eligibility requirements for cloud service providers and procurement preferences for European providers.
Digital Fairness Act: Planned for Q4 2026, this consumer protection legislation targets algorithmic manipulation, dark patterns, and pricing exploitation — primarily aimed at US platforms.
Quantum Act: A Q2 2026 framework for EU quantum technology investment, modelled on the EU Chips Act, designed to ensure European access to quantum computing infrastructure.
EU Chips Act: Already in force, providing subsidies and support for European semiconductor manufacturing. Intel, TSMC, and others have committed to European fab construction. The goal: reduce dependence on Taiwanese and South Korean chip supply chains.
The Honest Assessment: What Europe Cannot Build Quickly
European executives are candid about the limits of what can be achieved in the near term.
Commerzbank has noted that US providers’ superior range and maturity make them the best choice today for large-scale financial operations. Deutsche Bank warns that a sudden switch would cause systemic risk. Thyssenkrupp’s CEO noted that European firms are “not truly in the position to substitute all their IT solutions with European ones.”
The gap is largest in:
GPU-scale AI infrastructure. NVIDIA dominates the global AI compute market. European alternatives are years away from competing at scale. The EU’s EuroHPC supercomputing network provides some access, but not at the scale needed for frontier model training.
Developer ecosystems. GitHub, VS Code, NPM, PyPI, and the other tools European developers use daily are US-controlled. The switching cost for developer tooling is high and the alternative quality gap is significant.
Consumer platforms. WhatsApp, Instagram, YouTube, and Android are too deeply embedded in European consumer behaviour to be displaced by mandate. The DMA’s interoperability requirements create pressure for change, but adoption of European alternatives will be slow.
The realistic European digital sovereignty goal is not independence from US technology. It is “just enough” independence — the ability to maintain critical operations if US digital services became unavailable or were weaponised through policy. That goal is achievable within a decade. Full independence is not.
The Vucense Sovereignty Framework Applied to Europe
The European Eurostack project is the same principle Vucense covers at the individual and organisational level — applied to continental governance.
The sovereign stack at any scale — personal, enterprise, national — is built on the same foundations:
- Open-weight models you can run on infrastructure you control (Mistral, Llama 4, local Ollama instances)
- Self-hosted infrastructure where critical data resides (OVH, STACKIT, home servers, on-premise cloud)
- Open-source software with no single controlling entity (Linux, Nextcloud, Matrix, PostgreSQL)
- Encrypted communications under your jurisdiction (Signal, Proton, self-hosted Matrix)
- Sovereign payments that do not route through foreign-controlled networks (Wero, SEPA, the eventual digital euro)
Europe is building this at national scale. Individuals and organisations can build it today.
FAQ
What is the Eurostack? The Eurostack is a coordinated European effort — involving governments, the European Parliament, and private sector companies — to build sovereign digital infrastructure across chips, cloud, AI, payments, and communications. The goal is to reduce European dependence on US-controlled digital infrastructure from the current 80%+ to a level where critical operations can continue independently if US services were restricted.
Is France really replacing Microsoft Teams for 2.5 million civil servants? Yes. France’s LaSuite programme includes Visio, a sovereign video conferencing tool, which is being rolled out to French government users to replace Microsoft Teams, Zoom, and Webex. The transition is targeted for completion by 2027.
What is Mistral and why does it matter for European AI sovereignty? Mistral is a Paris-based AI company whose models are open-weight, European-developed, and competitive with US frontier models for many enterprise use cases. Its latest release — Mistral Small 4 — has a 256k context window and can be self-hosted on European infrastructure, creating a genuinely sovereign AI option.
Can European organisations realistically run without US cloud providers today? For most standard enterprise workloads, yes — OVH, STACKIT, and Hetzner provide adequate European alternatives. For frontier AI model training and inference at scale, European alternatives currently lag significantly. The practical approach for most organisations is a hybrid: European providers for standard workloads, selective US dependency where European alternatives do not yet exist.
What would happen if the US restricted access to digital services for European users? The European Council on Foreign Relations analysis describes this as legally plausible under current US executive authority. European organisations without local alternatives would lose access to AWS, Azure, Microsoft 365, Google Workspace, and US AI APIs. This is why the Eurostack is being treated as a security imperative rather than a competitive project.
