Global equity markets experienced a sharp selloff on Thursday and Friday following the Democratic party's sweeping victories in U.S. midterm elections, with investors citing concerns over potential AI regulation and data center construction delays as the primary catalyst [1][2]. In the U.S., major indices suffered significant losses: the Dow Jones Industrial Average fell 1,833 points or 3.44% to 51,523.06, the S&P 500 declined 4.36% to 7,353.73, and the Nasdaq Composite dropped 5.52% to 24,314.99—its worst session since April 2025 and entering correction territory, closing more than 10% below its October record high [2]. The technology sector bore the brunt of the selloff, with Nvidia falling more than 9% and the Philadelphia Semiconductor Index plunging more than 12% [2].
The contagion spread to Asian markets, where Japanese and South Korean stocks fell sharply on Friday morning [1]. Japan's Nikkei Stock Average dropped 7%, falling below the 60,000 threshold for the first time since mid-May, while South Korea's KOSPI declined 9% [1]. According to eToro market analyst Jakub Rochlitz, "The obvious catalyst for the sharp selloff is that markets are pricing in the midterm results" [2]. The selloff reflects investor concerns that Democratic policies may lead to increased AI regulation and potential delays in data center construction, which are critical infrastructure for artificial intelligence development and deployment [1].
President Donald Trump responded to the market decline by blaming Democrats for the losses, posting on Truth Social that "The Stock Market suffered one of the Worst Days in History based on the results of the Election" and warning that Americans' retirement savings and 401(k)s had been negatively impacted [2]. Beyond election-related concerns, investors have also raised broader concerns about the enormous borrowing and spending fueling the AI boom, particularly as technology companies expand data centers amid rising energy costs and uncertainty over future returns [2]. The market downturn notably came just one day after stocks rallied following the midterm elections, wiping out the previous session's gains [2].
CONCLUSION
The Democratic midterm election victory triggered a severe global market correction driven by investor fears of increased AI regulation and data center construction delays, with U.S. indices suffering their worst losses since April 2025 and Asian markets following suit. The technology sector, particularly semiconductor and AI-related stocks, bore the brunt of the selloff, with the Nasdaq entering correction territory. The sharp reversal from the previous day's post-election rally underscores heightened uncertainty regarding future AI policy and the sustainability of the current AI investment boom.
