autumn 2026 When a handful of companies control the digital in- frastructure that runs a continent’s banks, hospitals and transport networks, “sovereignty” stops being an abstract political concept. It becomes a business continuity question. For Europe, and Luxembourg specifically, building digital autonomy and resilience have become a top priority. The EU is determined to become a global leader in artificial intelligence (AI) and invests in ensuring both technological superior- ity and sovereignty. But the path to excellence is not a short one. A strategic decision Being sovereign in AI is not only a matter of tech- nology. Eva-Maria Hempe, Executive Director, Pub- lic Sector EMEA at AI computing provider NVIDIA, describes it as a five-layer stack: AI applications, AI models, infrastructure, hardware used to run AI workloads and energy production. Each layer implies a sovereignty decision. “You don’t have to control every single layer – no country in the world does that right now,” she said at the Nexus Luxembourg 2026 tech event. “Instead, you need to make strategic and informed choices about potential dependencies and decide how you will manage them.” Her co-panellist, Olivier Debeugny, CEO of the AI company OVHai LLM, pointed out that this does not concern only political leaders; businesses also need to make these choices. “For a business, sovereignty means strategic autonomy. You don’t want to be tied up by one solution only,” he said. Ahead of the curve Luxembourg is not trying to compete at every level of digital sovereignty. Instead, it has made deliberate bets and built the infrastructure to back them up. The country published one of Europe’s first national data strategies in 2019, at a time when most governments were still debating whether the data economy was real. In 2025, that strategy was followed by the ini- tiative “Accelerating digital sovereignty 2030”, which focused on data, AI and quantum technologies. This forward-oriented thinking reflects the coun- try’s economic story of deliberate reinvention. From steelmaking as its main economic activity, it pivoted to financial services in the 1980s. It then invested in the digital economy, followed by data, AI and super- computing. Each transition was the result of political decisions made ahead of the curve. The economic case often came later. “The key question was never ‘what is trending right now?’ but ‘what will matter in ten years, and how do we position the country now?’,” said the third panel- list, Mario Grotz, CEO of Luxembourg’s national in- novation agency Luxinnovation. “Investing in digital sovereignty now is essential for enabling AI innova- tion in the coming years.” For companies evaluating where to develop their digital innovations, that track record of following through matters as much as any policy document. Building a digital ecosystem for all To fulfil its ambitions, Luxembourg has invested in sovereign infrastructure, including ultra-secure and highly resilient Tier IV data centres, sovereign cloud solutions, supercomputing, data governance and an ecosystem that facilitates AI adoption and develop- ment. It serves all the actors using and innovating in AI: businesses, academia and public bodies. “A mod- el that only works for large research institutions or corporates leaves most of the economy behind,” said AI SOVEREIGNTY
