Tech sell-off continues as US Midterms and AI slowdown fears rattle investors
Technology stocks suffered a sharp sell-off this week as investors reassessed the outlook for artificial intelligence infrastructure following sweeping Democratic victories in the US midterm elections and growing concerns about whether massive AI investments will deliver expected returns.
Thursday, November 5, was particularly painful for Wall Street. The tech-heavy Nasdaq Composite plunged 5.5%, its steepest single-day decline since April 2025, while the S&P 500 dropped 4.4%. More than $3.2 trillion was wiped from the value of the US stock market, according to The Guardian.
The Nasdaq also entered correction territory, falling nearly 12% below its October 6 record close. A correction is generally defined as a decline of at least 10% from a recent peak.
Midterm Results Trigger Fresh AI Concerns
The sell-off followed Democratic victories in Tuesday's elections, with the party winning control of both chambers of Congress and several key governorships, including Texas.
Investors are concerned that the incoming Democratic lawmakers and state administrations could introduce tighter restrictions on data centre construction, potentially slowing one of the biggest drivers of technology investment and stock market growth.
Several Democratic candidates campaigned on addressing the environmental impact, electricity consumption and pressure on local communities caused by large data centres. Some also supported moratoriums or tighter approval requirements for new facilities.
The election results have therefore raised questions about whether technology companies will be able to maintain the pace of infrastructure expansion expected by investors.
AI Spending Faces a Reality Check
The political uncertainty comes as investors are already questioning the enormous amounts being spent on AI infrastructure and whether the resulting revenue will justify the investment.
Companies building data centres, supplying chips and leasing computing capacity have been particularly vulnerable. Nvidia shares fell approximately 9% on Thursday, while AMD dropped 17%. The Philadelphia Semiconductor Index also suffered a sharp decline.
Smaller AI infrastructure providers, including CoreWeave and Nebius, faced additional pressure over concerns about borrowing costs, financing requirements and the profitability of their businesses.
The market is increasingly shifting its attention from the promise of AI to the financial returns companies can generate from it. Any slowdown in data centre construction could affect chipmakers, cloud providers, power suppliers and other businesses connected to the AI supply chain.
Broader Financial and Macroeconomic Contagion
The sell-off spread beyond equity markets as institutional funds rotated into defensive positions. U.S. Treasury yields fell as investors sought the safety of sovereign debt, while high-beta asset classes faced correlated pressure. Bitcoin weakened alongside technology equities amid systemic risk-off positioning.
Wall Street analysts note that the midterms have catalyzed a long-brewing structural repricing. As public opposition to energy-hungry data centers intersects with scrutiny over tech corporate earnings, hyperscalers face mounting pressure to demonstrate concrete monetization frameworks before committing to further multi-billion-dollar compute expanTech Sell-Off Deepens as US Midterms and AI Slowdown Fears Rattle Investorssion.
