US senators float ‘Mined in America Act’ to boost BTC mining, codify reserve
The Mined in America Act, introduced by Senators Bill Cassidy and Cynthia Lummis, pairs a voluntary onshore certification with a government-backed Strategic Bitcoin Reserve — a deliberate policy package aimed at shifting hardware supply chains and creating a new outlet for certified miners. Its combination of phased equipment rules, domestic manufacturing support, and a Treasury purchase pathway makes this more than a symbolic bill; it lays out incentives and checkpoints that could materially change U.S. mining infrastructure.
Who this reshapes: miners, manufacturers, and national security planners
The bill targets a concrete imbalance: U.S. miners control about 38% of Bitcoin’s hash rate while roughly 97% of mining hardware is sourced from foreign manufacturers, primarily China’s Bitmain and MicroBT. Sponsors frame the program as addressing that dependency because hardware provenance creates points of geopolitical and supply-chain risk—examples include customs seizures of Bitmain ASICs flagged as radio devices that raised enforcement questions.
Instead of a broad industry subsidy, the proposal channels attention to specific actors: the Department of Commerce will run a voluntary “Mined in America” certification for mining facilities and pools, while existing federal technical bodies — the National Institute of Standards and Technology (NIST) and the Manufacturing Extension Partnership (MEP) — are charged with helping domestic vendors redesign and scale rigs to meet security and energy-efficiency targets.
How certification, phased hardware rules, and domestic support are supposed to operate
The bill requires certified operators to phase out equipment tied to foreign adversaries over a defined timeline that the Department of Commerce will set through rulemaking. Certification ties technical standards, provenance checks, and operational security to tangible benefits (discussed later), and it pairs with NIST/MEP assistance to push U.S. manufacturing capacity rather than create new standalone grant programs.
| Stage | Hardware rule | Compliance timing | Primary benefit for miners | Key watchpoint |
|---|---|---|---|---|
| Initial certification | Proof of sourcing and baseline security practices | Set in Commerce rulemaking | Eligibility for tax-exempt sales to Treasury | Stringency of provenance checks |
| Phased equipment transition | Gradual elimination of hardware linked to foreign adversaries | Multi-stage, deadlines to be published | Continued market access while upgrading fleet | Domestic supply chain ramp speed |
| Domestic manufacturing support | Technical assistance and integration with USDA and energy programs | Ongoing; aligned with existing program cycles | Access to projects that monetize excess renewable or stranded energy | Whether existing programs provide adequate financing |
How the Strategic Bitcoin Reserve and tax rules change miner economics
The bill formally codifies a Strategic Bitcoin Reserve inside the Treasury, extending the concept from President Trump’s 2026 executive order to a statutory framework. The reserve would be funded by law-enforcement seizures and by purchases from certified miners; those certified operators can sell newly mined Bitcoin to the Treasury and receive a capital gains tax exemption on that sale, creating an explicit fiscal incentive tied to certification.
That mechanism is designed to be budget-neutral: rather than allocating new appropriations, it uses tax treatment plus transfers to build a government-held reserve. Practically, this creates a predictable counterparty for certified miners but also alters liquidity dynamics — a regular pathway into government holdings could reduce the immediate sell-side pressure on spot markets while concentrating a portion of newly mined supply into a public reserve.
Decision checkpoints: when miners, manufacturers, and regulators should act or wait
Miners evaluating whether to pursue certification should track three near-term checkpoints: the Commerce Department’s rulemaking that defines compliance windows; the pace at which U.S. OEMs scale production under NIST/MEP guidance; and USDA or DOE program decisions that fund energy-coupled projects. If rulemaking sets aggressive equipment phase-out timelines before domestic supply can scale, miners face retrofit costs and potential operational disruptions.
Manufacturers deciding to invest in domestic ASIC production should weigh capital intensity against the policy signal: the bill creates demand via certified-miner incentives and potential Treasury purchases, but scaling fabs remains high-cost and dependent on whether the MEP and private partners can close specific funding and supply agreements. Regulators and budget offices will judge whether the tax exemption and purchase authority meet fiscal rules; that judgment will shape the reserve’s size and timing.
Quick answers to likely questions
Will certification be mandatory? No — the program is voluntary, but benefits like capital gains exemptions and Treasury purchase access are limited to certified operators, creating a built-in market incentive.
Where will the reserve’s Bitcoin come from? The bill directs the reserve to be built from law-enforcement seizures and purchases negotiated with certified miners; the exact purchase mechanics are to be specified in implementing guidance.
When should industry watch for concrete dates? The next critical signals are Commerce’s certification rulemaking and any implementing notices from NIST and MEP — those will set compliance windows and indicate whether the phased transition is achievable within industry timelines.
