The European semiconductor industry is caught in a dangerous vise, squeezed between two fires that threaten to erase the continent’s ambitions for technological autonomy. The alarm comes from a joint report by the EU Institute for Security Studies (EUISS) and the French think tank Institut Montaigne, published on Thursday as part of the EU-funded Chips Diplomacy project, now in its 18th month. The analysis puts on paper what many insiders feared: the future of chips made in Europe is as uncertain as ever, caught on one side by Chinese export controls on critical materials and on the other by deepening dependence on U.S. technology.

The problem is entirely geopolitical. Chinese restrictions target in particular rare earth elements and other materials essential for advanced chip production, while dependence on the United States plays out in design, fabrication tools, and dominant architectures. The report offers no easy way out: despite the investments of the EU Chips Act, Europe remains a fragile player in a global ecosystem dominated by non-European giants.

For those operating in the AI world—and especially for anyone evaluating on-premise deployment architectures—this scenario has concrete repercussions. The availability of high-performance GPUs and accelerators—key components for inference and fine-tuning of Large Language Models—depends heavily on supply chains that are now showing deep cracks. Prolonged material squeezes or a hardening of U.S. export licenses can translate into longer lead times, higher procurement costs, and infrastructure planning that hinges on extra-technical variables. The Total Cost of Ownership of a self-hosted cluster is no longer measured only in watts and FLOPs, but also in supply risk.

The Chips Diplomacy project was created precisely to analyze these dynamics, and the EUISS-Montaigne report is just the first piece of a path that is supposed to lead to policy recommendations. But the message is already clear: European digital sovereignty, so often invoked in data protection and GDPR documents, risks remaining an empty shell if not underpinned by a resilient hardware supply chain. It is not enough to host data on servers located in Frankfurt or Milan if those servers depend on components whose flow can be halted by a decision in Beijing or a strategic realignment in Washington.

The implications go beyond the industrial sphere. For organizations considering deployment of language models in air-gapped or on-premise environments for compliance reasons, supply chain fragility introduces a systemic risk factor. Even comparative assessments between cloud solutions and local infrastructure—addressed on AI-RADAR through dedicated analytical frameworks—must now assign a higher specific weight to the geopolitical variable. In other words, the question is no longer just “how much VRAM do I need to run a 70-billion-parameter LLM,” but also “how many external bottlenecks can block my access to that VRAM.”

The report does not hazard precise predictions, but its tone is enough to chill the enthusiasm of those hoping for a rapid European comeback. The feeling is that tensions between China and the United States, far from easing, are redrawing the global chip map without a reserved seat for Europe. A wake-up call that, if ignored, could leave the continent in technological subservience for the entire coming decade.
