Artificial Intelligence Stocks Tumble as Chinese Competitor Emerges

The S&P 500 plunged 1.5% on Monday, led by significant losses in technology stocks. Nvidia's decline of nearly 17% dragged the Nasdaq composite down 3.1%. The Dow Jones Industrial Average, however, bucked the trend, rising 0.7%.

This market volatility stems from the emergence of DeepSeek, a Chinese company claiming to have developed a cost-effective language model comparable to US giants.
