Online reports, on January 27, Bloomberg reported that U.S. stock index futures plunged sharply in early Asian trading on Monday due to concerns that China's DeepSeek artificial intelligence model might disrupt the technology market. As of 10:12 am Hong Kong time, S & P 500 futures fell by 1%, and Nasdaq 100 futures fell by 1.9%. DeepSeek released an upgraded artificial intelligence model last week and said it was comparable to OpenAI's technology. Over the weekend, reports that the product runs on lower-performance chips and costs less, raising questions about the dominance of U.S. technology companies such as Nvidia. Nirgunan Tiruchelvam, head of consumer and Internet at Aletheia Capital, said DeepSeek products seriously violate the argument that Silicon Valley's huge capital and operating expenses are the most appropriate way to respond to the trend of artificial intelligence. It raises doubts about the large amount of resources invested in artificial intelligence.
