Story summary

As of October 22, 2026, AI-related stocks are experiencing significant declines worldwide, leading to broader market downturns. The Nasdaq composite dropped 2.4%, while the S&P 500 fell 1.3%. Concerns over escalating costs for borrowing money and building data centers have shaken investor confidence in the artificial intelligence sector. For instance, despite Lam Research reporting better-than-expected summer profits and revenue growth, its stock price plummeted 11.8% due to fears of an AI bubble. Additionally, rising tensions with Iran pushed oil prices to their highest levels since May, contributing further to market volatility.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
