The U.S. Department of Defense executed a US$400 million purchase of a newly created series of convertible preferred stock in MP Materials, the only operating rare-earth producer in the United States — a purchase that closed on 11 July 2025. Alongside it came a warrant over additional common shares, a US$150 million loan from the Office of Strategic Capital for heavy rare-earth separation at Mountain Pass, a ten-year US$110-per-kilogram price floor on neodymium-praseodymium (NdPr) products, and a ten-year commitment that all magnets from a planned second facility find defense or commercial buyers. On an as-converted and as-exercised basis, the preferred and the warrant together represent about 15 percent of the company — positioning the Pentagon to become MP’s largest shareholder.

The price floor is the real story here, not the equity check. An equity stake is ownership; a ten-year floor is insurance against the single mechanism China has used most effectively to strand Western rare-earth projects — dumping NdPr oxide below the cost of producing it whenever a non-Chinese competitor threatens to scale. Beijing does not need to out-compete a magnet producer on quality. It only needs to make sure that producer's price collapses before its financing does.

Read together, the equity and the floor are two halves of one act: the DoD becomes an owner of the supply chain and a guarantor of the price that keeps the supply chain’s downstream buildout financeable. That is a different posture than a grant or a loan — Washington is taking on balance-sheet risk that a private lender would otherwise refuse to underwrite for a full decade, precisely because a decade is how long it takes a magnet-manufacturing base to actually get built. The private market read the signal immediately: JPMorgan and Goldman Sachs produced a commitment letter for US$1 billion of construction financing for the same facility, which is what a credible floor is supposed to unlock.

Note the authority, because it is the part that generalizes. This was not assembled from a single appropriation. The Department combined Title III of the Defense Production Act — which permits purchases and purchase commitments to run up to ten years, outside ordinary competition and acquisition rules — with money from the One Big Beautiful Bill Act, which explicitly confirmed that the Department may take equity positions in companies. The ten-year horizon of the floor is not a policy preference; it is the outer edge of what the statute allows. And the state kept upside: the Department is entitled to a share of revenue above the floor once the second magnet facility is operating.

This is capital statecraft at the layer where it is easiest to see and hardest to fake: sovereign capital deployed directly into a single named company, with a price mechanism built to survive a demonstrated Chinese tactic, under an authority designed for wartime industrial mobilization. What remains open is not whether the money moved — it moved — but whether the factory gets built on schedule and whether the floor ever has to pay out. A price floor that is never triggered is the cheapest weapon in the arsenal. One that is triggered every quarter for a decade is a subsidy with a different name, and the Treasury will notice the difference.
