Overview

• The U.S. government has imposed new export controls requiring licenses for Nvidia's H20 AI chips and AMD's MI308 GPUs, citing national security concerns.
• Nvidia announced a $5.5 billion charge as a direct result of the restrictions, while AMD anticipates an $800 million impact from inventory and purchase commitments.
• Shares of Nvidia and AMD fell by over 5% following the announcement, with broader declines across global tech stocks and semiconductor markets.
• Chinese tech giants like ByteDance and Tencent are accelerating efforts to develop domestic semiconductor alternatives due to reduced access to U.S. chips.
• Analysts predict sustained challenges for U.S. chipmakers in the Chinese market, with no assurance that export licenses will be granted.
