The CHIPS and Science Act became Public Law 117-167 when it was approved on August 9, 2022. Division A, formally titled the “CHIPS Act of 2022,” directed about $50 billion toward semiconductor manufacturing and research: $43 billion to the CHIPS for America Fund, $2 billion to a CHIPS for America Defense Fund, $500 million to an international technology security fund, and $200 million for workforce and education. The aim was to reverse a decades-long shift of advanced chip fabrication offshore and to reduce US dependence on a supply chain concentrated in East Asia.
The law paired direct subsidies with a 25 percent investment tax credit for chip manufacturing equipment, and it came alongside export controls restricting the sale of advanced computing chips and chipmaking tools to China. Together the two policies framed semiconductors as a matter of national security and economic competition rather than ordinary industrial policy.
For AI specifically, the act mattered because the entire field runs on a tiny number of leading-edge fabrication plants, most of them outside the United States. Funding domestic fabs was an attempt to put more of the AI hardware supply chain on US soil.
Why business readers should care: the CHIPS Act turned semiconductor capacity into explicit government strategy, with billions in incentives reshaping where chips - including AI accelerators - get built. Companies across the AI stack now operate in an environment where geography, subsidy and export law are first-order business variables.
