This bill, known as the "Mined in America Act of 2026," aims to bolster national security and promote domestic innovation in blockchain and artificial intelligence technologies. It directs the Secretary of Commerce to establish a voluntary Mined in America Certification Program for cryptocurrency mining facilities and mining pools. To qualify, these entities must be physically located in the United States or a friendly nation, not be controlled by foreign adversaries, and adhere to strict cybersecurity protocols. A key requirement is the phased elimination of proof-of-work mining hardware manufactured by entities related to foreign adversaries, reaching 0 percent by January 1, 2030. Certification under this program serves as a basis for eligibility or priority in various federal loan, grant, reimbursement, and procurement programs. Specifically, it amends Department of Energy programs, including Title XVII Loan Guarantees, the Infrastructure Reinvestment Program, and Smart Grid Investment Grants, to support certified projects. These projects focus on replacing foreign-made hardware with US or friendly nation-manufactured compute infrastructure, converting facilities into grid-interactive operations, and deploying systems for load shifting and emissions reduction. The USDA Rural Energy for America Program is also expanded to provide grants and loan guarantees for certified compute-focused entities in rural areas, supporting local grid reliability and employment. To further incentivize domestic operations, the bill provides a capital gains exemption for certified Bitcoin miners selling "qualified Bitcoin" to the United States for its Strategic Bitcoin Reserve. This reserve, along with a United States Digital Asset Stockpile, is formally established and codified, building upon a previous Executive Order. The Treasury Department is authorized to generate yield from Stockpile assets, such as through staking, to acquire additional Bitcoin for the Strategic Reserve, ensuring a budget-neutral approach. Bitcoin acquired for the Reserve must be verifiable as "mined Bitcoin" through on-chain demonstration. The legislation also mandates several strategic studies and support initiatives. The Department of Energy is directed to study the load-management capabilities and grid-balancing potential of domestic proof-of-work mining and high-density compute facilities. Concurrently, the Secretaries of Defense and Commerce must jointly assess the national strategic relevance of decentralized artificial intelligence infrastructure. Furthermore, the National Institute of Standards and Technology and the Hollings Manufacturing Extension Partnership are tasked with supporting the development and domestic manufacturing of secure, energy-efficient crypto-mining hardware. Finally, the bill promotes the export of US-produced mining equipment to friendly nations.
