Nvidia fell 16% as U.S. stocks broadly declined, with the Nasdaq leading losses. AI infrastructure makers took the heaviest hits, many falling double digits.
The selloff followed China's release of DeepSeek, an artificial intelligence model that appears to deliver strong performance at a fraction of the cost rival American companies charge. The development raised a question investors couldn't ignore: Do they still need expensive chips from Nvidia and other U.S. chipmakers if Chinese competitors can build capable AI systems cheaper?
This matters because Nvidia has dominated the AI boom. The company supplies the graphics processing units that train and run large language models. For months, demand seemed endless and prices kept climbing. DeepSeek disrupts that narrative by showing AI capability doesn't require the scale of spending companies like OpenAI and Meta have pursued.
What happens next depends on whether DeepSeek's efficiency reflects real advantages or just represents an early challenger. If the model holds up under scrutiny, chip demand could flatten. Investors will now scrutinize earnings reports and guidance from semiconductor companies more closely. Nvidia's next earnings call will face questions about whether AI infrastructure spending will continue accelerating or plateau.
