According to foreign media reports, the Biden administration plans to implement a new round of restrictions on the export of artificial intelligence chips from companies like Nvidia (NVDA.O) before leaving office. According to informed sources, the U.S. aims to limit the sales of AI chips used in data centers at both the national and corporate levels, with the goal of concentrating AI development in friendly countries and encouraging global companies to align with U.S. standards. Amid a surge in demand for AI technology, this move will expand semiconductor restrictions to most of the world. Informed sources say that the new regulations will set three layers of restrictions on chip transactions, possibly to be announced as early as Friday. Following this news, Nvidia, AMD (AMD.O), and others saw declines in after-hours trading on the U.S. stock market.
