Wall Street technology stocks drop on fears over artificial intelligence spending

United States stock markets fell sharply on Friday, October 30, 2026, driven down by a selloff in technology shares. The Guardian Business, Reuters, Investing.com News, Livemint, Seeking Alpha, and Yahoo Finance UK all reported that worries over artificial intelligence cash burn triggered the market decline. The Guardian Business reported that all three major United States stock indexes slumped, with the technology heavy Nasdaq index suffering the steepest loss. [1][2][3][4][6][7][8][9]

The market drop followed disappointing quarterly earnings reports released late on Thursday. According to the Guardian Business, disappointing financial results from Intel and Amazon sparked the technology rout. Chip stocks dropped sharply, which pulled the Philadelphia SE Semiconductor Index down to a monthly loss. [1][6][7]

All three major stock indexes closed lower for the week, the Guardian Business reported. Based on preliminary data, the S&P 500 fell 139.30 points, or 1.80 percent. Both the S&P 500 and the Nasdaq recorded monthly losses for October, while the Dow Jones Industrial Average ended the month with a gain. As FTMQ Business reported earlier, artificial intelligence technology stocks also experienced significant weekly losses earlier in October. [1][15]

Wall Street serves as a metonym for the American financial services industry and the New York Stock Exchange. The institution encompasses major investment banks and brokerages in Lower Manhattan. A Wall Street veteran cited by Fortune noted that an artificial intelligence slowdown could extend the long term durability of the boom by removing excessive market exuberance. [5][12][13]
