How major US stock indexes fared Monday, 1/27/2025

Wall Street’s superstars are tumbling as a competitor from China threatens to upend the artificial-intelligence frenzy they’ve been feasting on.

The S&P 500 fell 1.5% Monday. Big Tech stocks took some of the heaviest losses, with Nvidia down nearly 17%, and they dragged the Nasdaq composite down 3.1%. Besides chip companies, utilities hoping to electrify power-hungry AI data centers also tumbled. Stocks outside of AI-related industries held up much better, and the Dow Jones Industrial Average rose 0.7%.

A Chinese company called DeepSeek said it had developed a large language model that can compete with U.S. giants at perhaps a fraction of the cost.

On Monday:

The S&P 500 fell 88.96 points, or 1.5%, to 6,012.28.

The Dow Jones Industrial Average rose 289.33 points, or 0.7%, to 44,713.58.

The Nasdaq composite fell 612.47 points, or 3.1%, to 19,341.83.
