The US government has spent the past eighteen months deploying capital into critical minerals at a pace and in a form that has no real precedent in modern American industrial policy. This is not a grant programme or a research initiative. Washington is taking equity stakes in private companies, setting price floors for commodity output and making loan commitments before projects break ground.
On top of that, it is building a national reserve designed to buffer manufacturers against supply disruptions.
Understanding how each tool works matters to any company considering government engagement. It also matters to any investor trying to read the signals correctly. The instruments look similar on press release day. Their implications for a company’s balance sheet, operational independence and commercial exposure are quite different.
Tool One: Preferred Equity Stakes
The most visible form of government intervention has been direct equity investment. The Department of Defense, the Department of Commerce and the Department of Energy have each taken ownership positions in private critical minerals companies. They do so typically through preferred stock, which sits above common equity in the capital structure.
The MP Materials deal, announced in July 2025, is the clearest template. The DoD purchased $400 million of convertible preferred stock. That made it the company’s largest shareholder at approximately 15%. The DoD made the investment under the Defense Production Act. In return, the government gained financial participation in the upside if MP’s performance exceeds agreed benchmarks.

The Elmet Group deal in September 2026 followed a similar architecture. The Department of War committed $450 million in redeemable preferred equity. It also received warrants that could give the government up to 19.9% of Elmet’s common shares. The government secured the right to appoint an independent director and a non-voting board observer. That governance footprint goes beyond passive investment.
The Commerce Department took approximately a 10% equity stake in USA Rare Earth in January 2026. This formed part of a broader $1.6 billion commitment. Earlier interventions saw the government take stakes in Lithium Americas and Trilogy Metals.
Preferred equity protects the government’s position relative to common shareholders. It sits senior in a liquidation and typically carries a fixed return. The warrants that accompany many of these deals give the government further upside if the company’s value rises. For the company, the terms dilute existing holders. They also bring in capital that commercial lenders would not provide at comparable cost.

The governance rights deserve more attention than they typically receive. A board seat gives the government visibility into company operations. In some structures, it also provides formal approval rights over major decisions. Companies accepting these terms should treat that governance dimension as a real operational consideration, not a formality.
Tool Two: Conditional Loan Commitments
Alongside equity positions, the government has issued a series of large loan commitments. The word conditional carries material meaning and deserves careful reading.
A conditional loan commitment is a promise to lend, subject to the satisfaction of specified conditions — typically completion of due diligence, finalisation of loan documentation, regulatory approvals and evidence that the project is advancing on schedule. The money does not sit in the company’s bank account on announcement day. The government can withdraw the commitment if conditions are not met.
The Department of Defense’s Office of Strategic Capital announced a $725 million conditional loan commitment to Energy Fuels in 2026. The announcement explicitly noted that the loan remained conditional, pending further due diligence and finalisation of agreements.
The USA Rare Earth package included a proposed $1.3 billion senior secured loan under the CHIPS Act, also at the letter of intent stage at announcement. Perpetua Resources secured a $2.9 billion, 13-year loan from the US government for its Idaho antimony and gold project. MP Materials expected a separate $150 million DoD loan within 30 days of its equity deal closing, earmarked for the Mountain Pass heavy rare earth expansion.
The distinction between a conditional commitment and a funded loan matters enormously for investors reading company announcements. Committed capital changes a company’s financial position immediately. A conditional commitment does not. Government commitments have in some cases preceded project stalls or restructurings before the loan reached execution. Checking the specific conditions and the stage of documentation is essential before treating any commitment as cash.
Tool Three: Price Floors and Offtake Agreements
The most structurally innovative tool in the US critical minerals toolkit is the price floor combined with a government offtake agreement. It addresses a specific problem: critical minerals markets are dominated by Chinese-controlled pricing, and no Western developer can build a business plan around a commodity price set in Beijing.
The MP Materials deal established a 10-year offtake agreement for neodymium-praseodymium products at a price floor of $110 per kilogram. Under that structure, the DoD compensates MP for the difference between the benchmark NdPr price and the $110 floor, on all volumes either sold commercially or stockpiled. At the time the agreement was signed, the global NdPr benchmark in China sat at roughly $63 to $63.28 per kilogram. The floor therefore represented a premium of more than $40 per kilogram over prevailing market prices.
For the 10X magnet facility that MP plans to commission in 2028, the DoD went further, guaranteeing a minimum EBITDA floor of $140 million with a 2% annual escalator once the plant reaches capacity. The government also structured upside participation, meaning it benefits if prices and earnings exceed those floors.
The significance of this instrument is that it decouples project viability from Chinese market pricing. A developer who can show a lender a 10-year government price floor can build a financial model that does not depend on winning a price war with state-backed Chinese producers. Benchmark Mineral Intelligence noted at the time that the MP price floor could also help normalise pricing outside China and potentially anchor an ex-China rare earth price index — a market mechanism that does not currently exist in a functional form.
The offtake agreement works differently from the price floor. An offtake is a commitment to purchase a specified volume of output at agreed terms. The DoD structured a 10-year magnet offtake commitment for MP’s 10X facility, ensuring that production from that plant has a buyer before it opens. Combined with the price floor for upstream materials, the two instruments together address the two risks that typically kill critical minerals projects: revenue uncertainty and demand uncertainty.
Tool Four: Prepayment Facilities
The most structurally innovative tool in the US critical minerals toolkit is the price floor combined with a government offtake agreement. It addresses a specific problem: Chinese-controlled pricing dominates critical minerals markets, and no Western developer can build a business plan around a commodity price set in Beijing.
The MP Materials deal established a 10-year offtake agreement for neodymium-praseodymium products at a price floor of $110 per kilogram. Under that structure, the DoD compensates MP for the difference between the benchmark NdPr price and the $110 floor, on all volumes either sold commercially or stockpiled. When the parties signed the agreement, the global NdPr benchmark in China sat at roughly $63 to $63.28 per kilogram. The floor therefore represented a premium of more than $40 per kilogram over prevailing market prices.
For the 10X magnet facility that MP plans to commission in 2028, the DoD went further, guaranteeing a minimum EBITDA floor of $140 million with a 2% annual escalator once the plant reaches capacity. The government also structured upside participation into the deal, meaning it benefits if prices and earnings exceed those floors.
The significance of this instrument is that it decouples project viability from Chinese market pricing. A developer who can show a lender a 10-year government price floor can build a financial model that does not depend on winning a price war with state-backed Chinese producers. Benchmark Mineral Intelligence noted at the time that the MP price floor could also help normalise pricing outside China and potentially anchor an ex-China rare earth price index — a market mechanism that does not currently exist in a functional form.
The offtake agreement works differently from the price floor. An offtake commits a buyer to purchase a specified volume of output at agreed terms. The DoD structured a 10-year magnet offtake commitment for MP’s 10X facility, ensuring that production from that plant has a buyer before it opens. Combined with the price floor for upstream materials, the two instruments together address the two risks that typically kill critical minerals projects: revenue uncertainty and demand uncertainty.
Tool Five: Project Vault and the Strategic Reserve
The fifth instrument operates at the national level rather than the project level. Project Vault, announced in February 2026, is a $12 billion public-private initiative to establish a US Strategic Critical Minerals Reserve. The Export-Import Bank approved a direct loan of up to $10 billion to anchor the initiative. Approximately $2 billion in private capital completes the funding structure.
EXIM described Project Vault as its Deal of the Year at its 2026 annual conference. The reserve is structured as an independently governed public-private partnership that stores essential raw materials in distributed facilities across the United States. Early anchor manufacturers include Clarios, GE Vernova, Western Digital and Boeing as participating buyers. Hartree Partners, Mercuria Americas and Traxys are among the key suppliers.
The initiative is designed to give US manufacturers a buffer against supply disruption — access to a shared reserve of approximately 60 targeted minerals rather than each company individually sourcing and storing material. One description that circulated in industry circles was that of a Costco for critical minerals: a shared purchasing and storage structure that spreads cost and risk across multiple participants.
Project Vault will initially source from global markets, including China, then pivot over time toward domestic supply. That sequencing reflects an honest acknowledgment that domestic production cannot meet near-term needs on the timeline the reserve requires.
For mining companies, the relevant implication is that Project Vault creates an institutional buyer ready to absorb domestic output as it comes online. A project that can demonstrate alignment with Vault’s mineral priorities and quality requirements has a visible offtake pathway that did not exist two years ago.
The Private Capital Counterpart
Government tools alone are not sufficient. The instruments described above are designed explicitly to crowd in private capital, not to replace it. The MP Materials deal included a $1 billion financing commitment from JPMorgan Chase and Goldman Sachs for the 10X magnet facility, alongside the DoD equity and loan components. That combination of public and private capital is the intended model.
JPMorgan’s broader Security and Resiliency Initiative, announced in October 2025 and expanded to a $1.5 trillion, 10-year commitment, allocated up to $10 billion in the bank’s own capital for direct equity and venture capital investments in sectors including critical minerals. By October 2026, reporting indicated the Strategic Investment Group led by Todd Combs had directed approximately $5 billion across ten companies in capital-intensive sectors including defence, aerospace, healthcare, critical minerals and energy. The specific allocation to critical minerals within that total has not been disclosed separately.
The point of that private commitment is not the headline number. It is that JPMorgan’s participation in a specific critical minerals deal — as in the MP financing — signals to the broader lending market that the sector is bankable. That signalling function is what the government’s tools are ultimately trying to trigger.
What the Tools Do Not Do
Each of these instruments is powerful in its specific application. None of them resolves the underlying economics of an uncompetitive project.
A preferred equity stake does not guarantee that a mine will produce at cost. A conditional loan commitment does not guarantee that the conditions will be met. A price floor does not guarantee that the ceiling on costs will hold. A prepayment facility does not guarantee that the project will deliver on schedule. Project Vault does not guarantee that domestic supply will be available when the reserve needs to pivot away from imported material.
Companies that have accepted government instruments should not treat them as substitutes for commercial discipline. Projects that need a government price floor to be viable at all are in a structurally different position from those where the floor serves as a hedge against downside scenarios.
Investors reading government announcements should also distinguish between commitment and execution. The total headline figure across announced commitments in the critical minerals space has grown substantially. The amount that has reached company bank accounts, been drawn on loan facilities and been deployed into actual construction is a smaller number.
What the Industry Should Watch
The conversion rate from commitment to funded loan is the most important metric to track across the conditional commitments outstanding. Monitoring which deals have progressed from letter of intent to signed agreement to first drawdown reveals the real pace of deployment.
Governance rights are underappreciated. Board seats and observer roles give the government visibility and, in some structures, effective veto power over major corporate decisions. Companies should model those constraints before accepting equity on those terms.
Price floors create a reference point for sector pricing. The $110 per kilogram NdPr floor in the MP deal is now a data point that other rare earth developers, their lenders and their offtake partners will reference. That has implications for how non-government offtake agreements get negotiated.
Project Vault’s mineral list is not yet fully public. Companies developing materials outside the initially disclosed priority minerals should verify eligibility before building Vault assumptions into their business plans.
Private capital follows government signals, but it follows execution more. JPMorgan’s participation in the MP deal came after the DoD equity and price floor were in place. The sequence matters. Government derisking precedes commercial bank lending. Projects that are still at the government commitment stage should not assume bank financing will follow automatically.
A Toolkit, Not a Guarantee
The five tools the US government has deployed — preferred equity, conditional loans, price floors with offtakes, prepayment facilities and strategic reserves — collectively represent a more sophisticated industrial policy than anything Washington has attempted in the minerals sector in decades.
Each tool addresses a specific financing barrier. Together, they are designed to create the conditions under which private capital will follow. Whether they succeed depends not on the size of the commitments but on the number of commitments that reach the production stage.
That is the question the market is watching. The toolkit is built. The projects now have to deliver.
