US Lawmakers Introduce Bill to Restrict AI Chip Exports to China Amid Rising Domestic Competition

• •The MATCH Act aims to restrict advanced semiconductor equipment sales to China.
• •Chinese firms captured 41% of the AI server market in 2025, impacting Nvidia's dominance.
• •Huawei has become a leading supplier of AI chips, benefiting from U.S. export restrictions.

A bipartisan group of U.S. lawmakers introduced the MATCH Act to limit the sale of advanced semiconductor manufacturing equipment to China, aiming to close loopholes in AI export controls. This legislation seeks to curb China's ability to establish a fully domestic AI supply chain, as imports of semiconductor machinery surged from $10.7 billion in 2016 to $51.1 billion in 2025. The act would expand restrictions on chipmaking machines and associated services, targeting key Chinese chip companies. Concurrently, Chinese firms have gained significant ground in the AI chip market, with local vendors capturing 41% of the AI server market in 2025, largely at the expense of Nvidia, whose market share dropped from 95% to 55%. Huawei emerged as a major player, delivering 812,000 AI chips, while the U.S. sanctions have driven China to enhance its domestic semiconductor capabilities. The situation highlights the geopolitical tensions surrounding technology and national security, with both countries striving for dominance in AI capabilities.
