The concentration of artificial intelligence exposure in global equity markets is more severe outside the United States than previously assumed, according to a new analysis from MarketWatch.
While US investors have long debated the risks of overexposure to a handful of tech giants, the report highlights that international markets are increasingly reliant on these same US-based firms for AI-driven growth, creating a structural dependency that amplifies volatility.
This dynamic is accelerating the divergence between American technology leaders and their European counterparts.
As US firms capture the lion's share of new market value generated by the AI boom, European companies are struggling to keep pace, leading to a persistent underperformance in non-US tech indices.
The disparity is not merely a matter of valuation multiples but reflects a fundamental shift in where innovation and capital are being deployed.
Global equity markets extended their decline on Tuesday, with technology stocks bearing the brunt of the selling pressure.
