European companies are investing more money in artificial intelligence than ever before, but the gap separating them from their American counterparts is not narrowing — it is widening. That was the picture painted by European Central Bank President Christine Lagarde in a September 14 address detailing how the continent is accelerating into an AI race it is losing by a significant margin.

Euro area firms are expected to direct roughly 10% of their total investment toward AI this year, up from about 9% in earlier estimates. That progress, however, is modest against the wider backdrop: the United States controls approximately 75% of the world's AI computing capacity, while Europe's share sits at about 5%. Computing capacity — the data-center hardware used to train and run AI systems — is a core input for frontier development, and at those shares the US lead amounts to roughly fifteen times Europe's capacity.

Spending Is Rising, but the Gap Persists

The growth in European AI investment is not trivial. AI-related borrowing accounted for roughly 25% of the overall increase in credit to euro area firms during the first quarter of 2026. More than half of euro area employees now use AI tools in their jobs — a figure that has doubled over the past two years, a sign of how widely the technology has already spread through European workplaces even as the investment gap with the US persists.

Even so, the pace of digital investment in the United States has grown twice as fast as in Europe over the same two-year period.

European Households Are Funding Their Competitor

The funding imbalance also runs household portfolios. European households collectively hold around €440 billion in US technology companies, meaning ordinary Europeans are effectively bankrolling the American AI dominance that their policymakers are trying to catch up with.

Production figures for cutting-edge AI models underscore the dynamic. In 2025, the United States produced 59 notable AI models, while China produced 35. France and the United Kingdom each produced one — a combined output nearly 30 times smaller than the United States', a measure of how concentrated frontier model development remains outside Europe.

What Lagarde Proposes

Lagarde's prescription centers on two priorities: building stronger European computing infrastructure and integrating the continent's fragmented capital markets. The two priorities map onto the imbalances her address describes: computing infrastructure speaks to Europe's 5% share of global computing capacity, while capital market integration speaks to the €440 billion of household savings held in US technology companies. She cited estimates suggesting that rapid AI adoption could boost euro area productivity by up to 4% over the next decade. The same indicators Lagarde cited — AI's share of euro area investment, Europe's slice of global computing capacity, and the geography of notable-model output — are the ones to watch for any shift in the trajectory.
