Background & analysis
On Thursday, October 22, 2026, a selloff in AI stocks pulled global markets lower, according to The Guardian. The S&P 500 fell 1.2%, its worst single day since July, while the Nasdaq composite dropped 2.6%. The weakness in tech shares was severe enough to obscure strength elsewhere in the US market, where most individual stocks actually rose on the day.
The report linked investor sentiment to the cost of borrowing for datacenter construction and AI chip purchases. Investors, it said, are worried that these costs are too high and could threaten the current AI boom, even as companies in the sector continue to report growth. The same report noted that oil prices climbed to their highest levels since May amid concerns about the war with Iran.
The available information stops at that trading day's market moves and the concerns described above; the material offers no further developments or additional responses from the parties involved.
