Story summary

As of October 23, 2026, US tech stocks experienced significant declines due to investor concerns over the sustainability of substantial capital investments in artificial intelligence (AI). The Nasdaq Composite fell by 2.6%, its steepest drop since June 5, and the S&P 500 declined by 1.21%. This market downturn was led by Meta’s shares dropping nearly 7% despite raising projected spending for this year to $135 billion to $145 billion. Other major tech companies like Nvidia and Lam Research also saw their stock prices fall sharply, with the semiconductor index sinking over 6%, reflecting worries about high borrowing costs for AI infrastructure development and inflated stock valuations.
