Eurozone households hold around €440 billion in US technology companies, and European Central Bank President Christine Lagarde says that means European savings are helping finance the American AI boom while Europe gets left with the bill and the bragging rights of someone else’s machine. Speaking in Vienna on Monday, Lagarde warned that the money parked across the eurozone is flowing into Nvidia, Alphabet and other US tech firms, even as the economic gains are built elsewhere. “The companies are being built elsewhere,” she said. “Last year the United States produced 59 notable AI models, and China produced 35. France and the United Kingdom produced one each.”
Capital Moves, Workers Don’t
The ECB’s own analysis, published on Tuesday, shows the scale of the imbalance. Eurozone households held nearly €10 trillion in bank deposits as of May 2026. They keep around one-third of their financial assets in deposits, compared with 11% among US households. Around 80% of eurozone households own no shares, bonds or investment funds. That’s the quiet architecture of the European financial order: savings sit idle for most people, while the returns and the power flow upward and outward.
The ECB says limited resources, knowledge gaps, low trust and concerns about risk keep many Europeans out of financial markets. More than 60% of eurozone households held most of their wealth in property, around a quarter relied mainly on bank deposits, about 10% invested indirectly through pension and insurance products, and just 4% held a substantial share of their wealth directly in financial markets. So when Brussels talks about “mobilising” savings, it’s talking about a system where ordinary people are already boxed into narrow choices, then told to become more “invested” in the same market logic that keeps them at the edge of it.
Those who do want exposure to AI often end up buying American technology companies through investment funds and pensions. Jeremie Peloso, chief strategist for Europe at BCA Research, said investing in US technology was not necessarily a problem for European households. “US tech has been outperforming European indices for the past 10 years,” he said, adding that international investments can help savers spread their risks. He also said a weaker euro has sometimes increased the returns made by euro-based investors on dollar-denominated assets. But he warned that the US technology sector had become highly concentrated, leaving investors exposed to a relatively small group of companies affected by many of the same market forces.
The Bond Market’s Quiet Drain
Ben Barringer, head of technology research at Quilter Cheviot, said European capital had moved abroad because many of the world’s leading technology companies had been built and expanded outside Europe, offering stronger growth prospects and investment returns. That’s the market speaking in its usual dead language: capital goes where capital can squeeze more out of labour, infrastructure and public subsidy, and the rest of Europe is told to call it efficiency.
Buying an existing US technology share does not provide fresh money to the company, but strong investor demand can support its valuation and make it easier to raise capital by issuing new shares. When European retail investors buy newly issued shares, as happened when SpaceX invited them to participate in its IPO in June, they provide money that the company can use for investment. The route is familiar. Savings are pooled, markets are polished, and the money ends up where the returns are already concentrated.
The biggest technology companies are also borrowing heavily through the bond market. Major hyperscalers are expected to spend more than $1 trillion (€870bn) on capital investment by 2028, according to an ECB analysis. That spending covers data centres, advanced chips, electricity supplies and network infrastructure. Lagarde said major US hyperscalers issued more than $100bn (€87bn) in bonds last year and now account for close to one-tenth of new euro-denominated bond issuance by non-financial companies. Five large US hyperscalers have around €40 billion in euro-denominated bonds outstanding, according to the ECB. European funds, insurers and pension schemes that buy these bonds are directly lending money to American technology companies.
The consequences don’t stop at the border, because capital never does when it’s chasing yield. Heavy US bond issuance can contribute to higher global yields, while long-term interest rates in the eurozone often move alongside US rates. “Europe will bear part of the price of this boom in its own borrowing costs,” Lagarde said. “The question is whether it will also get the growth that goes with it.”
Brussels’ Answer: More Markets
Rapid AI adoption could raise eurozone productivity by as much as 4% over a decade, according to ECB estimates. But Europe remains far behind the US in the infrastructure needed to develop and run AI. Lagarde said the United States hosts around 75% of global AI computing capacity, compared with approximately 5% in Europe. The European Commission estimates that the gap between demand for data-centre capacity and available supply in the EU could reach 19 gigawatts by 2036, and closing it could cost as much as €600 billion.
Eurozone companies are expected to devote around 10% of their investment to AI in 2026, while AI-related borrowing accounted for approximately one-quarter of the first-quarter increase in credit to companies, according to ECB estimates. Europe clearly has capital. What it doesn’t have, at least by the ECB’s own telling, is a system that keeps that capital from being siphoned into the US tech machine.
Peloso said there is no shortage of capital in Europe, only a problem of channelling funds. He added that Europe also had a considerable number of technology companies, but relatively few were publicly traded, leaving retail investors and funds restricted to public markets with a limited choice of European technology investments. Mistral shows the contradiction neatly. The French AI company raised €3 billion last week in the largest equity fundraising by a European technology company, but ordinary savers could not participate directly because its shares are not publicly traded.
Barringer said simply encouraging investors to direct more money towards European AI would treat the symptom rather than the underlying cause. “The challenge is not simply a lack of available capital, but creating the conditions for more world-class European companies to emerge and compete globally,” he said. That would require deeper venture-capital markets, greater willingness to finance higher-risk businesses and rules that support innovation while maintaining appropriate oversight.
The EU’s main response is the Savings and Investments Union. It is intended to make it easier for households to invest and for European companies to obtain funding across national borders. Proposed measures include simpler, potentially tax-advantaged investment accounts, changes to supplementary pensions and efforts to reduce the cost of operating across different European financial markets. The EU has also introduced its Listing Act, designed to make it cheaper and easier for companies to go public, with simpler listing documents and rules allowing founders to retain greater control after their companies enter the stock market.
These reforms could help more European technology companies grow and eventually become accessible to ordinary investors. But they cannot guarantee that European households will choose them over American companies offering stronger prospects. Peloso said channelling more savings into businesses would be a multi-year process requiring easier regulation, a more favourable environment for start-ups, deeper venture-capital and private-equity markets, and stronger incentives for households to invest. Barringer similarly argued that policy should focus on building stronger companies rather than simply directing savings towards a preferred sector. “If the underlying foundations are not strong enough to support innovation, simply directing more savings towards the sector is unlikely to solve the problem,” he said. Europe has the capital, the institutions and the speeches. The money still goes where the returns are.
