Defence offtake deals with price floors make critical minerals projects infrastructure-grade. The shift could reverse if policy changes.
MP Materials Corp. / DE currently carries an Alpha Score of n/a, giving AlphaScala's model a neutral read on the setup.
The U.S. Department of Defense’s 10-year offtake agreement with MP Materials Corp. (NYSE: MP) includes a $110 per kilogram price floor. That single number transforms how credit committees underwrite rare earth mining projects. For the first time, a critical minerals asset can be modelled as infrastructure, not a speculative commodity play.
For a decade, investment theses for critical minerals leaned on electric vehicle penetration and renewable energy build-out. That narrative moved capital. The structural problem was that demand tied to policy cycles and adoption curves carried irreducible uncertainty. Project financiers priced that uncertainty as higher capital costs. The energy transition never delivered the predictable, government-backed cash flow required to make a mine bankable at scale.
Defence procurement rewrites the model. Governments negotiate offtake agreements with price floors and long tenors. The U.S. Department of Defense’s contract with MP Materials mirrors a power purchase agreement (PPA) in renewable energy. Lenders can model a base-case revenue stream that does not depend on spot commodity price forecasts. That reclassification alters the cost of debt and shrinks the equity dilution a project must absorb. The valuation floor that emerges is one that pure-play commodity projects rarely achieve.
The MP Materials contract runs 10 years with a $110 per kilogram minimum price for rare earth products. If spot prices rise above that floor, the company captures the upside. If spot prices fall, debt service remains covered. Lenders can stress-test a base case without relying on commodity price forecasts. That certainty is the mechanism that reclassifies bankability.
The MP Materials deal sits inside a larger apparatus. Project Vault combines a $10 billion EXIM Bank direct loan facility with a $12 billion public-private strategic reserve structure. The Defense Industrial Base Consortium has signalled willingness to deploy $100 million to $500 million per project through equity-like instruments alongside traditional contracts. In February, the Forum on Resource Geostrategic Engagement (FORGE) launched with 54 nations, moving allied supply chain coordination from aspiration to architecture.
Private capital has followed. Venture capitalists deployed more than $628 million in U.S. rare earth startups in 2025, equivalent to 90% of global sector funding, after the Trump administration committed to minimum price guarantees. The flow is rational. A concentrated policy-driven capital pipeline, however, introduces a specific exposure: if government priorities shift, the same signal that pulled money in can yank it out. (For deeper valuation risk, see our earlier analysis of MP Materials’ $10B valuation debate.)
Canada holds deposits of all 12 minerals NATO identifies as essential for defence manufacturing and actively produces 10 of them. Its projects operate in allied, traceable, CFIUS-compatible jurisdictions. In the current financing framework, that jurisdictional status feeds directly into bankability. Lenders discount political risk when the host nation is a Five Eyes member with a stable mining code.
Canada has signed more than 30 critical mineral agreements in recent months. Earlier this year, the Prospectors and Developers Association Conference (PDAC) unlocked $12.1 billion in mining project capital. Defence-linked offtake agreements are now crystallizing.
Germany’s Thyssenkrupp Marine Systems signed a teaming agreement with E3 Lithium to integrate Canadian lithium into the Canadian Patrol Submarine Project, a program valued at more than $30 billion. This is not a generic memorandum. It ties a specific mineral input to a specific defence platform with a defined budget. That specificity lets lenders underwrite the offtake directly.
The deal illustrates a structural advantage for Canadian projects: European and allied defence offtake diversifies revenue away from sole U.S. dependence. Projects serving multiple allied buyers carry a more durable risk profile than those anchored entirely to U.S. procurement frameworks.
Canada and the United States are allies and competitors simultaneously. Both countries court the same partners for the same capital. The bilateral relationship navigates tariffs and sovereignty tensions Ottawa has not faced in decades. Canadian defence analysts note that critical minerals give Canada genuine leverage in broader trade negotiations. The market, however, is still pricing Canadian projects that secure European offtake at similar multiples to U.S.-only plays. That parity implies an asymmetry the market has not yet corrected.
Projects that are closing financing today share a specific profile:
Defence acts as the anchor tenant, not the whole building.
Projects built around a single government demand signal carry policy-cycle risk that current valuations may not fully reflect. A change in administration, a budget reallocation, or a shift in geopolitical priorities can reprice that offtake. The market is treating many of these contracts as permanent constructs. Several extend beyond election cycles.
The $628 million that flowed into U.S. rare earth startups in 2025 was not pure speculation. It followed explicit policy signals: minimum price guarantees, EXIM Bank facilities, and the Defense Industrial Base Consortium’s co-investment framework. Venture capital moves faster than government appropriations. Should the next Congress or administration slow the funding pipeline, early-stage companies dependent on a single offtake signal could face a sudden re-rating.
This is not an argument against the trend. It is a reminder that policy-driven capital flows are two-way. The same mechanism that pulls money in can push it out when the signal changes.
The most durable investment thesis in this space treats defence as the foundation of a diversified, commercially viable revenue stack. Defence offtake provides the underwriting anchor. Commercial OEM contracts, technology licensing, or recycling streams supply the upside. Lenders are already differentiating. Projects with multiple demand verticals receive better terms. A project selling to both a defence department and an automotive manufacturer can demonstrate revenue resilience if one buyer delays orders. A project reliant on a single defence contract cannot.
Full chain-of-custody documentation is no longer a compliance checkbox. It is a pricing input. Lenders ask whether a supply can trace its material from mine to magnet. A project that demonstrates CFIUS-compatible sourcing and allied-only processing secures a governance discount on its cost of capital. The FORGE framework, with 54 nations, is building standards that will make traceability a hard financing requirement.
The shift in critical minerals finance is accelerating. Defence demand has accomplished what the energy transition narrative promised and never fully delivered: it has made a subset of projects genuinely bankable at scale. The capital now moving into the sector follows sovereign demand signals, allied supply chain architecture, and a geopolitical realignment.
The next concrete test is how many Canadian, Australian, and European projects lock in defence-linked offtake agreements with non-U.S. allied buyers. A project that secures a long-term rare earth offtake with a Japanese or Korean defence contractor adds an additional layer of revenue diversity. The market has not yet priced that diversity. Investors tracking this gap are effectively betting that the discount will close as multi-jurisdictional demand becomes visible.
For investors, the central question is not whether the financing shift is real. It is whether the specific projects and jurisdictions they are evaluating are built for a durable position within it, or only for the current policy moment. Assets with diversified offtake, allied jurisdictional status, and traceable supply chains will be the ones lenders reward first.
