Historical data shows that when CapEx for a new technology exceeds 2-3% of GDP, a market crash follows within a few years. Today's AI infrastructure spending has reached similar levels, with 93% of GDP growth coming from AI CapEx, suggesting the current tech boom is unsustainable and headed for a correction.

Europe's investment opportunity in AI lies not in creating foundational technology, but in its adoption. European companies leading in AI adoption are showing significant earnings outperformance and trade at a 27% discount to US equivalents, representing a distinct and undervalued growth angle.

The real investment case for AI in Europe is not in creating foundational models but in adoption. The continent's vast 'old economy' index has significant potential for productivity gains. As AI's return on investment becomes clear, Europe could be re-rated as a major beneficiary of AI adoption, capitalizing on its large industrial base.

A key driver for renewed interest in European equities is not just a search for value, but a strategic move to hedge against volatility in the US AI sector. Investors, while maintaining their AI holdings, are allocating new capital to Europe to diversify and mitigate risk from the AI complex's price swings.

The extreme market concentration in AI stocks might not end in a tech crash. An alternative is that other sectors like financials, industrials, and energy will "catch up" as they benefit from the massive capital expenditure required to build out AI infrastructure, broadening market performance.

Europe's primary AI bull case is not in creating foundational AI but in its large base of "AI adopters." These firms, a quarter of the index, show strong earnings outperformance and trade at a significant 27% discount to US equivalents, presenting a unique investment angle.

The massive investment in AI data centers is fueling a powerful economic cycle of equity appreciation and consumer spending. This dependence creates a significant risk, as any slowdown in this capital expenditure boom will have far-reaching negative consequences for the broader economy.

The narrative of a broad AI investment boom is misleading. 60% of the incremental CapEx dollars in the first half of 2025 came from just four firms: Amazon, Meta, Alphabet, and Microsoft. Owning or being underweight these four stocks is a highly specific bet on the capital cycle of AI.

The global stock market rally is largely an extension of the U.S. AI story. International markets are benefiting from demand for AI-related inputs (e.g., minerals from Latin America) and as global investors seek to diversify away from highly-valued U.S. tech stocks into other, relatively cheaper markets.
