On January 11, news broke that the Biden administration's planned new restrictions on AI chip exports triggered a sharp decline in the share prices of multiple chip companies upon the opening of the U.S. stock market on January 10. NVIDIA's share price plummeted by over 3%, AMD's by nearly 6%, and Broadcom's by more than 2%. According to prior reports, the Biden administration is anticipated to issue a new round of chip export restrictions as early as January 10, which will be structured into three tiers: a limited number of U.S. allies will retain unrestricted access to U.S. semiconductors, the majority of countries will face new export controls, and certain nations will be completely barred from importing datacenter chips. The Information Technology Industry Council (ITIC), representing tech giants including Amazon, Microsoft, and Meta, voiced concerns that these new regulations could hinder U.S. companies from selling computing systems abroad, thereby ceding market share to competitors. Similarly, the Semiconductor Industry Association (SIA) expressed apprehension about this potential regulatory measure, fearing that it will impose global constraints on U.S. exports of advanced integrated circuits and introduce burdensome licensing requirements.
