US Stock Futures Plunge, AI Stocks Face Carnage as Democrats Sweep Midterms

TradingKey - Democrats sweep US midterms, US stock index futures plunge, market panics over strict scrutiny on AI data centers, expecting a carnage in AI stocks.

On November 4, 2026, Eastern Time, as vote counting in the US midterm elections progressed and Democrats showed strong momentum in both the Senate and the House of Representatives, the probability of them controlling Congress continued to soar. US stock index futures plunged in an extreme flight to safety during Asian and European trading sessions, with Nasdaq 100 futures and S&P 500 futures moving significantly lower, falling by over 0.5%.

The market is filled with apprehension regarding a Democratic-controlled Congress. Among them, Ryan Detrick, Chief Market Strategist at Carson Group, posted on the X platform, stating, "The worst combination is a Republican president paired with a Democratic-controlled Congress. At present, the movement in the futures market seems to confirm this."

In addition, market anxiety over high-valuation AI computing sectors, regulatory scrutiny on hyper-scalers' CapEx, and semiconductor subsidy policies erupted, triggering strong concerns on Wall Street that AI-concept stocks could face a valuation carnage. Nicholas Mugalli, CEO of World Trade Securities, posted on the social platform X, stating, "Tonight is nothing short of a brutal bloodbath for all investors, especially those in the AI sector."

If Democrats control Congress, they may comprehensively upgrade AI regulation, antitrust enforcement, and data center energy consumption reviews, which is the core reason for market panic. Previously, Democratic congressional leaders had repeatedly warned of potential risks concerning AI model monopolies, data privacy, and national security. Having swept both the Senate and the House of Representatives, Congress is expected to accelerate AI safety regulatory bills and antitrust hearings. In addition, addressing the immense power demand and carbon emissions of hyperscale data centers, a Democratic legislature may raise green energy usage thresholds or levy carbon taxes, directly driving up the marginal cost for giants such as Microsoft (MSFT), Meta (META), Alphabet (GOOG), and Amazon (AMZN) to build out AI computing infrastructure.
