Every other sector in this document — AI, robotics, defense, EVs, energy infrastructure — depends on the same dozen-or-so raw materials . Rare earths for the magnets in motors. Lithium for the batteries. Copper for the wires. Silicon carbide for the next generation of power chips. Industrial gases for every fab.
Here's the wrinkle: China spent twenty years locking up most of the world's supply of all of them. Now the West is racing to rebuild a parallel non-Chinese supply chain — and that costs trillions, takes a decade, and creates a generational opportunity for the few Western companies that already have mines, refineries, and processing capacity.
You don't have to pick which downstream theme wins. If AI wins, materials win. If robots win, materials win. If EVs win, materials win. If reshoring wins, materials win. The same dozen rocks sit underneath every story.
You cannot build a motor without a permanent magnet. You cannot build a permanent magnet without rare earths. China makes 90% of both.
Every electric motor — in an EV, a wind turbine, a robot, a missile guidance system, a smartphone vibrator — uses a neodymium-iron-boron (NdFeB) permanent magnet . For high-temperature applications (motors, especially EV drive motors) you additionally need dysprosium and terbium (the "heavy" rare earths). China refines ~90% of rare earths globally and produces ~95% of permanent magnets . The MP Materials and USA Rare Earth names appear in AI Choke 01 (rare earths flow to AI lasers and magnets); they belong here too because the magnet thesis spans every other sector. We add net-new exposure via Lynas — the only at-scale ex-China rare-earth refiner.
China imposed export controls on heavy rare earths in 2025. If the Nov 27, 2026 deadline isn't extended, prices spike and any non-Chinese supply becomes strategically priceless.
Only at-scale ex-China rare-earth miner + refiner
Australian miner that operates the only commercial-scale rare-earth refining facility outside China — in Malaysia. Building a second refinery in Texas (Lynas USA, ~2026 first production) with US Department of Defense partnership. Owns the Mount Weld mine in Western Australia, one of the highest-grade rare-earth deposits on Earth.
Covered in detail in AI Choke 01 — included here for completeness
Both names sit primarily in the AI rare-earths chokepoint above. The thesis here is identical with an added flavor: EV motors and humanoid robots use the same magnets as AI laser systems . Any pure-play rare-earth name is implicitly a multi-sector chokepoint. See AI Sector for full cards.
