Highlights

• China controls ~91% of refined rare earths and ~92% of magnets, creating a midstream vulnerability that capital markets and governments are scrambling to address through new mines, processing facilities, and strategic stockpiles.
• J.P. Morgan's report conflates advisory interest with analysis, positioning deals like MP Materials as blueprints while glossing over the gap between construction milestones and sustained, globally competitive production capacity.
• The real shift is critical minerals becoming a financialized national security infrastructure, but investors must distinguish scarcity theater from processing reality—permitting, solvent extraction buildout, and metallurgy talent remain the hard industrial gates that money alone cannot dissolve.

J.P. Morgan, in a recent report, (opens in a new tab) says critical minerals demand is climbing fast because AI data centers need power and hardware, the energy transition needs metals, and defense budgets are rising. Supply chains—especially rare earth refining and magnets—are concentrated in China, so governments and capital markets are pushing new mines, processing, and stockpiles. Translation: demand up, chokepoints matter, geopolitics is now a cost line.

That core framing is fair. The voice is not disinterested.

The Hard Truths They Nail

J.P. Morgan puts a sharp number on the central vulnerability: China supplies 91% of refined rare earths and 92% of magnets. That’s the midstream truth investors can’t diversify away with slogans.

They also correctly tie NdPr magnet demand to EVs, wind, and defense platforms. Modern high-performance motors still use rare-earth permanent magnets, and large-scale rare-earth separation still relies on industrial solvent extraction—no scalable miracle process has displaced it. (That’s the bottleneck, not the rock.)

Where the Narrative Gets “Helpful”

The MP Materials passage reads like research—but it also reads like a case study in why the author is in the room. J.P. Morgan highlights its advisory/financing role and calls the DoD–MP transaction a potential “blueprint.”

That doesn’t make it false; it makes it incentivized. When the same institution that structures the deal also spotlights its precedent-setting value, investors should mentally add a disclosure label: strategic storytelling attached to fee-bearing activity.

Also, refine the phrasing around “fully integrated magnet producer.” MP Materials is building what it describes as a vertically integrated rare earth metal, alloy, and magnet manufacturing platform in Texas. Company materials reference commissioning phases, qualification runs, and ramp schedules—real and meaningful progress. But commissioning and ramp-up are not the same as sustained, scaled, globally competitive output across full demand cycles.

Rare Earth Exchanges™ is openly rooting for MP Materials, America’s rare earth element treasure trove. A resilient domestic magnet supply chain is a national security imperative. At the same time, our obligation is to investors and policymakers: distinguish construction from capacity, and ambition from industrial maturity. We can support the mission while still calling the field as we see it.

The Signal REEx Readers Should Bank

The real news is the financialization of industrial policy: critical minerals are being framed as national security infrastructure, which invites bigger balance sheets, structured finance, and stockpiles.

Investors should separate:

• Scarcity theater (often overstated)
• Processing reality (very real)
• Capital-market momentum (accelerating)

Final Word

J.P. Morgan is directionally right on demand and concentration. The risk is believing capital alone dissolves bottlenecks. Permitting, solvent extraction buildout, metallurgy talent, and magnet QA pipelines are still the hard gates. The rare earth story is not just money—it’s industrial competence.
