US Army Backs REalloys as China's Magnet Curbs Bite into Defense Supply Chain
Washington's first direct Army partnership with a rare earth processor tests whether non-Chinese magnet supply can break Beijing's grip.
The US Army has signed a partnership with rare earth processor REalloys, putting Pentagon weight behind the only non-Chinese North American facility capable of processing heavy rare earths, according to reporting published Wednesday (2026-07-29).6
The deal matters because it moves the rare earth fight from policy statements to procurement. REalloys holds an exclusive 80% offtake from the Saskatchewan Research Council's operating plant, has existing government contracts, and counts a Korean magnet manufacturing partner among its backers. The company has roughly $130 million in cash, Russell 3000 membership, and feedstock deals spanning multiple continents, with qualification underway for a major defense procurement deadline.6
China's export controls are the backdrop. Terbium, one of the two heavy rare earths at the core of military-grade magnets, is up 103% this year. Chinese rare earth magnet exports to the United States fell 22.5% year-over-year in the first two months of 2026, even as overall magnet exports rose, meaning Beijing is redirecting supply away from American buyers while keeping global volumes intact.3
The template for what comes next is antimony. In August 2024, Beijing imposed export controls on the metal, which goes into more than 200 types of military munitions. Within weeks, the price went from $1,400 per ton to $38,000, a 2,600% spike, and shipments to the United States fell 97%.3
Beijing fired another warning shot on Monday (2026-06-22), issuing export controls against a raft of US firms, including two prominent rare earth companies. Bryan Bille, a policy analyst at Benchmark Mineral Intelligence, called it a "warning shot" rather than a full embargo.2
The market math is straightforward. Morgan Stanley projects rare earth magnet demand rising three to five times over the coming decade, driven by defense platforms, electric vehicles, robotics, and AI infrastructure. The supply response outside China remains thin, with the sector dominated by miners holding large resource estimates and separators still running pilot plants.6
That imbalance raises questions about how far the Army partnership can stretch. One analyst argued that concentrating nearly $11 billion in a single incumbent doesn't fix the underlying market structure, and that a rare earth processing startup with novel extraction chemistry and just $2 million in revenue is not scalable through other transaction authority contracts alone, unattractive to most institutional investors without an anchor customer.4
The US is not the only front. South Korea has become a battleground for downstream demand, with Chinese-made EVs capturing one third of the Korean market last year and accounting for 30.9% of EV registrations in the first quarter of 2026. That gives Beijing a demand lever in a key ally's market even as Washington pushes to build alternative supply chains.1
Meanwhile, the European Union pitched a minerals deal to Brasília in late June (2026-06-30), joining a flood of interest in Brazil's rare earth deposits. But it is unclear whether Brasília is ready to meet the moment, and any Brazilian supply remains years from production.5
The Trump administration has gestured toward taking equity stakes in critical mineral champions, following its Intel model. But the subsidy-for-subsidy approach has limits when the bottleneck is not capital but processing capacity and qualified offtake.4
For traders, the signal is in the price action. Terbium's 103% gain this year reflects a market that believes Chinese export controls are tightening, not loosening. The antimony precedent shows how fast these markets can move once Beijing acts, and how completely US shipments can collapse.3
The Army's backing of REalloys is the first concrete sign that Washington is trying to lock in non-Chinese processing capacity before the next round of controls. Whether that capacity scales beyond pilot plants, and whether South Korea's EV market stays open to Chinese imports, will shape how much of the magnet supply chain actually escapes Beijing's grip.6
The qualification deadline REalloys is racing toward is the real test. If it clears the bar, the Army has a domestic source of heavy rare earth magnets and a template for future partnerships. If it slips, the gap between US demand and non-Chinese supply gets wider just as Beijing tightens the screws.6
