US Senators Float Reserve-Backed Bitcoin Mining Bill, Raising Nationalization Prospect

Senators Cassidy and Lummis introduced the Mined in America Act on March 30, 2026, creating a voluntary certification for domestic Bitcoin miners, codifying a Strategic Bitcoin Reserve, and enabling a Treasury procurement channel that would allow certified miners to sell newly mined BTC to the government in exchange for a capital gains tax exemption. The bill aims to shift hardware sourcing away from adversary countries, require phase-out of foreign-made equipment by decade-end, and tie renewable-energy and DOE/USDA benefits to certification. Market implications include a potential demand floor from a price-insensitive sovereign buyer, a narrowed secondary-market float for newly mined BTC, and likely margin compression and consolidation among miners during an expensive domestic hardware transition — dynamics that could be bullish for spot Bitcoin price but disruptive for mid-tier miners.
