European Central Bank President Christine Lagarde warned in Vienna on Monday that Europe cannot rely solely on imported artificial intelligence from the United States and must develop its own capacity or risk giving foreign technology suppliers leverage over every corner of its economy. Lagarde said Europe's first priority must be expanding its own computing infrastructure, noting the continent already lacks sufficient data center capacity to meet existing demand and that on current trends the gap is projected to grow more than sixfold within a decade, with closing it potentially costing as much as €600 billion over ten years, chips included. She said the E.U.'s new gigafactories are a start but fill only a fraction of the shortfall, and that Europe must also develop AI models competent enough for the majority of use cases and hosted on European systems, pointing to French firm Mistral and a company in San Sebastián that adapted a Chinese open model to top independent benchmarks among European models. Lagarde said euro area households hold roughly €440 billion in U.S. technology firms while U.S. hyperscalers issued more than $100 billion in bonds last year, and cited ECB estimates that rapid AI adoption could raise productivity by as much as 4% over a decade. She argued the buildout requires patient equity rather than debt alone, noting European households save roughly €1.4 trillion a year but that markets to channel that capital into homegrown technology do not yet exist at the necessary scale. The remarks came alongside prior Brussels steps, including European Commission legislation to restrict sensitive government cloud contracts to providers meeting European sovereignty standards through the Cloud and AI Development Act, and a roughly €30 billion E.U. tender for up to seven AI gigafactories pairing up to €10 billion in public funding with at least €20 billion in expected private investment, with construction targeted to begin in 2027.
