Nvidia's Market Cap Plummets Nearly $600 Billion in Biggest Single-Day Loss in U.S. History

Nvidia saw a substantial decrease of more than 13 percent in its stock value, representing the largest single-day drop in U.S. history, amounting to nearly $600 billion in market capitalization. DeepSeek, a Chinese AI company, has become the top downloaded free app on Apple's U.S. App Store, surpassing OpenAI's ChatGPT. The Nasdaq index, which is tech-heavy, dropped by almost 600 points or nearly 3 percent during a broader market selloff on Monday. Investors are now scrutinizing the steep expenses associated with AI investments by major tech companies such as Google and Microsoft, especially as DeepSeek claims to offer lower training costs.
