European Stocks Slide as Fears of US AI Rules Grow After Midterms

what happened

European stock indexes fell sharply on Friday, with the pan-European Stoxx 600 closing down 1.84%. Britain's FTSE 100 lost 2.21%, Germany's DAX 2.33%, France's CAC 40 1.83% and Switzerland's SMI 1.14%. According to dpa-AFX, citing RTTNews, the sell-off reflected worries that the Democrats' strong showing in the US midterm elections could lead to tighter AI regulation and slower data center expansion.

Teleperformance dropped 15% after cutting its 2026 revenue outlook. In Germany, Deutsche Post, Siemens, Rheinmetall, Allianz and Deutsche Bank fell 3% to 5%. Daimler Truck slipped 3.7% despite a 73% jump in third-quarter adjusted operating profit, as nine-month results remained below last year's levels.

Economic data was mixed. UK house prices fell 1.2% year on year in October, a faster decline than September's 0.1%. France's trade deficit widened to €7.3 billion in September, well above the €5.8 billion expected. German industrial production rose 0.7% month on month in September, beating expectations of no change.

why it matters

Markets are focused on the uncertain policy outlook for AI, whose impact on tech and data center investment could weigh on shares in Europe and the US. Weak French trade data alongside better-than-expected German output gives mixed signals for the euro area economy.
