U.S. stocks plunged Thursday as investors sold off artificial intelligence stocks, with market experts saying the selloff reflects deeper concerns about the AI boom's sustainability. The Dow Jones Industrial Average fell 1,833 points, or 3.44%, while the Nasdaq Composite dropped 5.52% in its worst session since April 2025. The Nasdaq also closed in correction territory, down at least 10% from its October 6 record closing high.
The rout stems from growing concerns about the massive spending and borrowing fueling the AI boom and whether those investments will ultimately generate returns. Paul Mueller, an economist with the American Institute for Economic Research, identified debt as Wall Street's primary worry, saying the market is concerned about enormous debt obligations being issued by tech companies to build data centers, particularly as interest rates have risen and political uncertainty around data center construction has increased.
Adam Patti, CEO of VistaShares, said investors are contending with three simultaneous concerns. Political uncertainty intensified after the midterm elections, with wins in several key data center states raising fears of increased regulation, slower permitting and opposition to rising power bills. Investors are also questioning return on investment, asking how long major technology companies can sustain current spending levels while free cash flow turns negative. Additionally, semiconductors represent an increasingly crowded trade in the market, and such crowded positions tend to unwind sharply.
Power availability has emerged as another critical concern. Patti stated that power represents the real bottleneck in AI today, more significant than chip supply, and warrants investor focus. The massive electricity demands of AI data centers raise questions about grid capacity, utility costs and how quickly new facilities can come online. Despite this pressure, data center development may shift toward areas with greater available power and fewer permitting obstacles.
Jakub Rochlitz, EToro market analyst, suggested that heavy borrowing combined with crowded trades amplified the selloff. The mix of election results and disappointing tech earnings results provided the spark needed to trigger the market decline, with large numbers of crowded and leveraged trades unwinding simultaneously. However, Patti noted that the selloff represents a valuation and sentiment reset rather than a fundamental change in AI demand. Paul Mueller advised ordinary investors to focus on diversification and long-term holding strategies while ignoring market volatility.
