Nomi Prins — The Part of the Rare Earth Supply Chain That's Actually Broken
Not mining, not magnets — the broken link is separation & refining, where China controls ~91% (and ~99% of heavy rare earths). That midstream bottleneck is where the next wave of government money is pointed.
One-line take: ex-China NdPr oxide prices have doubled since January — a capacity story, not supply-demand. The real bottleneck isn't mining or magnets but separation & refining: pulling chemically near-identical rare earths apart takes hundreds of solvent-extraction stages. The US shut its own down in the 1980s over uranium-trace regulations; China kept going and now controls ~91% of separation capacity (~99% for heavy rare earths dysprosium/terbium/yttrium). Ex-China NdPr trades a 63% premium to inside-China — pure scarcity, supplied mainly by Lynas in Malaysia plus pilot plants. China's Nov-10-2026 export-control suspension expiry + US Section 4872 (bans China-sourced rare earths for defense contractors from Jan 1, 2026) intensify the scramble. Note: built from the free portion — the recommended separator (DoD-funded, 10× faster proprietary tech, North American plant commissioning this year) is reserved for Founders+ (its name and buy-up-to price are paywalled).

2. Key points
The price spike is a capacity story
- Amid the war and oil shock, ex-China NdPr oxide (the blend in every permanent magnet) has doubled since January — not a supply-demand spike but a capacity one. Most investors watch mining or magnets; the real bottleneck is the step between them.
Separation & refining is the hard part
- Before a rare earth can go into a magnet, EV motor or missile guidance, it must be separated from 15+ chemically near-identical elements — hundreds of stages of solvent extraction through banks of mixer-settlers, run continuously for weeks. China controls ~91% of global separation capacity; for heavy rare earths (dysprosium, terbium, yttrium) it's ~99%.
Why the US stopped
- In the 1980s US firms pulled rare earths from iron-ore and phosphate by-products. Then uranium-proliferation regulations targeted anyone handling ores with trace uranium — harmless or not — and domestic production shut almost overnight. China kept processing, refined the chemistry and scaled for three decades.
The price gap tells the story
- Ex-China NdPr trades a 63% premium over the same oxide inside China — same specs, the only difference is where it was separated. Not tariffs or shipping; pure missing capacity. Non-China buyers compete for output from a handful of facilities (mainly Lynas in Malaysia plus pilot plants) — not enough at any price.
The policy clock is ticking
- Beijing suspended part of its rare-earth export controls in Nov 2025 in a trade truce; that suspension expires Nov 10, 2026, on top of restrictions in place since April 2025. Meanwhile US Section 4872 bans defense contractors from acquiring China-mined/refined/separated/melted rare earths (full chain as of Jan 1, 2026) — but certifying a China-free chain is very hard when ex-China separation is barely a fraction of need.
The opportunity
- That midstream gap is where the next wave of government investment is pointed. The Founders+ pick is a rare-earth separator with proprietary tech ~10× faster than conventional methods, DoD funding in place, a North American facility commissioning this year, and downstream customer agreements secured — full analysis (with the buy-up-to price) reserved for Founders+ subscribers.
3. In plain English
A jargon-free summary of why each name is in the piece. (Plain-language companion to the table above; renders on each name's consolidated page.)
RareEarths — Rare earths / NdPr (commodity) Positive
Rare earths are a group of metals needed for the powerful magnets in EVs, wind turbines and missiles. Everyone talks about mining them or making the magnets, but Prins says the truly broken link is in the middle: "separation," the painstaking chemical process of pulling these nearly-identical metals apart so they're usable. China does about 91% of this step worldwide (99% for the rarest "heavy" types), because the US shut its own plants in the 1980s over outdated nuclear rules.
The tell is price: outside China, this material now costs 63% more than the exact same stuff inside China — purely because there's almost nowhere else to get it processed. With US defense rules now banning China-sourced rare earths and China's export controls set to snap back in November 2026, buyers are scrambling. That's why Prins is pointing at companies that can do the separating outside China.
LYSDY — Lynas Rare Earths Neutral
Lynas isn't a rated pick here — Prins names it as proof of how scarce non-Chinese processing is. When a Western or defense buyer needs rare earths separated outside China, Lynas (which runs a plant in Malaysia) is basically one of the only options, alongside a few tiny pilot operations. There simply isn't enough of this capacity to go around, which is the whole point of the article.
