Rare-earth magnets & motors

Who owns it. China produces roughly 90% of the world's sintered NdFeB magnets and a near-monopoly share of the separated heavy rare earths — dysprosium and terbium — that keep those magnets from demagnetizing at the temperatures inside a drone motor running flat-out (CSIS). The moat is not geology; Mountain Pass and Mount Weld prove the West has ore. The moat is three decades of accumulated separation chemistry, metal-making, strip-casting and sintering capacity run at ~300,000 t/yr scale — enough to price NdPr below any greenfield Western producer's cost of capital — plus a licensing regime Beijing has now twice weaponized: the April 2025 controls on seven heavy rare earths and finished magnets, then the October 2025 extraterritorial expansion, suspended only until November 10, 2026 (China Briefing). A NdFeB magnet is a low-single-digit slice of a drone's bill of materials and 100% of its propulsion. That asymmetry is the trade.

What breaks it. Not mining — magnet-making, plus price insulation to survive Chinese flooding. Washington has now underwritten both. The DoD's July 2025 deal with MP Materials set a $110/kg NdPr floor for ten years and backstops 100% offtake from the "10X" magnet campus — ~7,000 t/yr at the Northlake, Texas site MP selected in February, the anchor of ~10,000 t/yr of total planned US capacity alongside Independence (MP Materials). Vulcan Elements landed a $1.4B public-private package — anchored by a $620M Office of Strategic Capital loan and a $50M CHIPS letter of intent, with the balance in private capital and an $80M OSC loan to recycling partner ReElement — for a second 10,000 t/yr plant (NIST). USA Rare Earth commissioned its first commercial sintered-NdFeB line at Stillwater in March 2026, with customer deliveries starting this quarter (GlobeNewswire). Stack in e-VAC and Noveon and announced US capacity approaches ~30,000 t/yr by 2028–29 — real, but a tenth of China's, and most of it still short heavy-RE feedstock. That is the binding constraint: Lynas's Malaysia circuit is the only commercial ex-China Dy/Tb source (Mining.com), and Energy Fuels poured its first US terbium oxide only this year (Northern Miner). Breaking the choke takes floors (done), mandates (dated), and three to five years of unglamorous metallurgical execution — with slippage risk on display in Lynas's Seadrift, Texas wobble.

The repricing catalyst. January 1, 2027. NDAA §844/§854 and DoD's implementing rule ban NdFeB and SmCo magnets touched by Chinese melting or fabrication from defense systems, with False Claims Act teeth (Breaking Defense). The Pentagon is simultaneously buying one-way attack drones by the tens of thousands — and industry reporting says that fleet overwhelmingly flies on Chinese magnets today (PR Newswire, a vendor-sourced figure, but consistent with the ~98% China magnet-share estimates repeated across outlets). Compliant magnet supply cannot cover compliant magnet demand in 2027; somebody pays scarcity prices, and markets should start handicapping that in H2 2026 — especially if Beijing lets the export-control suspension lapse on November 10. Own the few balance sheets that can legally sell a magnet, or a motor, into that gap.
