AI spending fears send Nasdaq down 2.86% in technology sell-off

Investors now demand clearer profits from companies funding artificial intelligence.

31 Oct 2026

Overview

Wall Street’s technology sell-off erased hundreds of points from major indexes as investors questioned whether the vast spending on artificial intelligence will produce profits soon enough. The fell 2.86%, the dropped 1.82% and the lost 1.10%, with technology and chip stocks bearing most of the damage. The decline followed weak signals from Alphabet, Amazon and Intel. Alphabet’s record share drop reflected concerns over rising cash use, while Amazon reported a $42.4 billion over 12 months and Intel warned of weaker profit and continued personal-computer weakness.3

Big technology companies committed more than $200 billion to AI infrastructure in one quarter, but high interest rates and financing costs make data centers harder to justify before customer demand is proven. That has revived doubts about whether AI valuations have outrun future earnings. The losses were concentrated in technology rather than showing a broad economic collapse, but they reduced global risk appetite and pressured Indian technology shares. A lasting repricing would require further weak earnings, reduced spending plans and declining ; stronger profits and continued demand could show this was only a correction.
