Tech stocks tumble amid AI spending concerns, Oracle cuts 21,000 jobs

Global technology stocks experienced a significant downturn on June 22nd and 23rd, 2026, amid a widespread AI-related sell-off that raised concerns about the sustainability of the artificial intelligence boom. Major indices like the tech-heavy Nasdaq Composite and the S&P 500 saw notable declines. This market correction impacted companies across the globe, with particular vulnerability seen in chipmakers and memory chip manufacturers, notably in South Korea where the KOSPI index, dominated by such firms, plummeted.

Prominent tech giants including Nvidia, Alphabet, Amazon, and recently public SpaceX were among those whose shares fell, reflecting investor apprehension over soaring valuations. Analysts attribute the slump to "AI bubble" fears, substantial capital expenditures by companies on AI infrastructure with unproven returns, and the increasing likelihood of higher interest rates impacting economic growth.

While some market observers view this as a necessary rebalancing, others are debating whether the current market conditions present a buying opportunity or signal a more extended period of instability.
