The index slumped 5.5% on Thursday, driven by a broad sell‑off in artificial‑intelligence stocks, marking its steepest decline in nineteen months.
Nasdaq suffered its worst one‑day drop in nineteen months on Thursday, plunging 5.5% as investors rapidly exited AI‑focused equities.
Broad AI sell‑off drives market tumble
The decline was led by a sharp sell‑off in high‑profile artificial‑intelligence stocks, including megacap names that had surged earlier in the year on hype around generative models.
Key AI stocks under pressure
- Nvidia (NVDA) fell more than 7%, erasing billions in market value.
- Microsoft (MSFT) slipped 4% after its AI cloud revenue guidance missed expectations.
- Alphabet (GOOGL) dropped 5% as its AI‑related ad spend outlook was revised downward.
Smaller AI‑centric firms such as OpenAI‑backed startups and Anthropic also saw their shares tumble, reflecting heightened sensitivity to any hint of slowing demand for AI compute power.
Market context and investor sentiment
The broader Nasdaq composite fell in tandem, while the S&P 500 and Dow Jones Industrial Average posted modest declines, indicating that the panic was largely confined to the technology sector.
Analysts cite a combination of factors: tighter monetary policy, concerns over AI spending cycles, and a recent earnings miss from several AI‑heavy companies that sparked a risk‑off mood.
