Europe's AI Investment Gap: Where €440 Billion in US Tech Companies Leaves Europe Behind

European households have around €440 billion invested in US technology companies, including Nvidia and Alphabet. European Central Bank President Christine Lagarde warned that European savings are financing the expansion of artificial intelligence (AI) in the United States without Europe receiving a comparable share of the economic benefits.

The problem is not a lack of money; rather, it's getting more funds to companies that can grow. Eurozone households held nearly €10 trillion in bank deposits as of May 2026, but only around one-third of their financial assets are invested in shares, bonds, or investment funds. Around 80% of eurozone households own no shares, bonds, or investment funds.

Many Europeans who want exposure to AI invest in American technology companies through investment funds and pensions. However, investing in US technology is not necessarily a problem for European households. Jeremie Peloso, chief strategist for Europe at BCA Research, said that international investments can help savers spread their risks and that the US tech sector has been outperforming European indices for the past 10 years.

However, Barringer, head of technology research at Quilter Cheviot, 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.
