NEW YORK, Jan. 28 -- Wall Street's tech giants faced sharp declines on Monday amid concerns over a Chinese competitor potentially disrupting the booming artificial intelligence (AI) sector.

The S&P 500 dropped 1.7% in afternoon trading, on course for its steepest loss in over a month. Tech-heavy Nasdaq Composite took a significant hit, falling 3.2%, as major technology stocks suffered. Nvidia led the slide, plummeting 16%, AP reports.

In contrast, industries outside the AI sector showed resilience. The Dow Jones Industrial Average rose by 137 points, or 0.3%, at 12:42 pm Eastern Time. The Dow's smaller exposure to tech helped cushion its performance compared to the S&P 500 and Nasdaq.
