**NVIDIA Faces Historic Stock Decline Amid AI Sell-Off**

On January 27, U.S. and European AI-themed stocks experienced a massive sell-off, shaking market confidence. The Nasdaq Composite Index dropped 3.07%, with leading AI company NVIDIA witnessing a staggering 17% plunge in its stock price. This drop wiped out $592.7 billion in market value, marking the largest single-day market value loss in U.S. history.

Other tech giants were also affected. Broadcom's stock plummeted 17%, AMD saw a 6% decline, and Microsoft slipped by 2%. Companies in related fields, such as utilities, also faced steep losses. American Electric Power's stock fell by 21%, while Vistra dropped 29%.

Analysts attribute the sell-off to the rise of Chinese AI startup DeepSeek. Its AI assistant recently overtook OpenAI’s ChatGPT as the most downloaded free app in the U.S. Apple App Store. DeepSeek’s model reportedly outperformed OpenAI in several tests, with development costs under $6 million, significantly undercutting competitors.

The disruption caused by DeepSeek has shaken investor confidence in established AI firms, raising questions about future competition and innovation in the AI sector. As markets recalibrate, the long-term impact of this shake-up remains uncertain.
