Semiconductors are the foundation of the modern economy and of military power, and the contest to design, manufacture, and secure semiconductors defines the US-China semiconductor competition. Export controls, subsidies, and the drive to reshore fabrication have turned chips into one of the most consequential arenas of technology policy. This hub follows the semiconductor race: the role of critical inputs such as gallium and other semiconductor minerals in chip production, the US-China semiconductor competition over advanced nodes, the exposure of concentrated supply in Taiwan, and the AI chips and advanced chips driving demand. Demand for AI chips is now the engine of the industry, and control over AI chips has become a central goal of export controls. Fellows and analysts assess the vulnerabilities in chip supply chains and the effectiveness of export controls on semiconductors. Explore expert analysis and commentary on semiconductors and the competition at the heart of economic security.
