Thanks to @CongressmanRaja, Ranking Member of the House Select Committee on the CCP, for spotlighting how our public-private partnership with the DoD is helping get more production online—and can serve as a blueprint for onshoring critical supply chains across the economy.…
A rare earth story without the clichés. No Deng Xiaoping quotes. No “not that rare” takes. Just sharp, timely journalism. Read it here—or in tomorrow’s Wall Street Journal.
America’s Biggest Rare-Earth Producer Makes a Play to End China’s Dominance $MP wsj.com/business/us-ra…
Fascinated we are talking about magnets are rare earth materials as some of the keys to AI supremacy. (Yes I get the tech). Prehistoric dirt meets Agents. @MPMaterials CEO James Litinsky discussing the $AAPL deal and USG investments. $MP
If you’re doing anything to Reindustrialize America, think 10x bigger. This is a multi trillion dollar opportunity and we are in the first inning.
Strong words from the most bipartisan committee in Congress 👇
🚨Statement from Chairman @RepMoolenaar and Ranking Member @CongressmanRaja on the MP Materials and Department of Defense announcement: "As Chair and Ranking Member of the House Select Committee on the Strategic Competition Between the United States and the Chinese Communist…
We’ve been working quietly with Apple for nearly FIVE YEARS to develop the advanced recycling technologies that make this agreement possible. This news, announced on the heels of our historic agreement with the Department of Defense, reflects growing public and private sector…
After 5 years of technical collaboration, we’re proud to announce a $500M agreement with @Apple to supply 🇺🇸-made rare earth magnets from 100% recycled materials Production at our Fort Worth facility, Independence, begins 2027 and will ultimately support hundreds of millions of…
Hear hear!
Viewing the MP/DoD deal as “un-American” overlooks 230 yrs of US industrial policy. The US has paired public capital w/ private enterprise since its founding…usually when markets couldn’t shoulder the risk of building critical capacity. Alexander Hamilton’s 1791 Report on…
I’ve got to be honest with you, my @Sustainabledud1 -- you gave us a solid laugh in the middle of a pretty serious day. And for that, I salute you.
Truth is crazier than fiction
Serendipity. Eight years ago today—July 10, 2017—MP Materials rescued Mountain Pass from the brink. We were 8 people with big ambitions. Today, we’re 850 strong—and backed by the U.S. Department of Defense. Through noise, doubt, and headwinds, Team $MP delivered. Quietly.…
America doesn’t always choose the easy path—but when tested, it finds the courage to do what’s right 🇺🇸
So proud 🇺🇸 MP Materials Announces a Transformational Public-Private Partnership with the U.S. Department of Defense – Multibillion-dollar DoD commitment – New “10X” magnet facility to be constructed – 10-year price floor + offtake agreements – DoD positioned to become MP’s…
In the latest episode of “Uncut Gems: Junior Miner Edition,” U.S. Critical Materials Corp. skips the sales pitch and just posts the instructions their web designer gave them. Yes, really. They published the how-to, not the what. You can’t make this stuff up. 🫣…

Years of hard work by a fierce and committed team—through endless noise and doubt—are starting to come into focus Watch
This is NdFeB alloy flake—the starting point for high-performance magnet production $MP produces it at our Independence facility in Texas using NdPr metal made on-site from oxide refined at Mountain Pass Our process delivers precise chemical and microstructural control—yielding…
Worthy of strong consideration in reconciliation 👇
🚨The Senate just introduced the Rare Earth Magnet Security Act of 2025—a bill to create a tax credit for U.S.-made high-performance magnets It’s a companion to previously introduced House legislation and is sponsored by Sens. Graham, Mullin & Cortez-Masto If ever there were a…
This chart is such a comically scummy tactic. Maybe someone should make a defensible, honest chart?
$USAR vs $MP MP has very small amounts of the Essential Heavy Rare Earths
Those with a defeatist mentality are so weak and so wrong
“Too far behind” “Can’t compete” “Can’t scale” We’ve heard it all before! $MP has already proven a fully integrated U.S. rare earth supply chain is not only possible, but within reach We’ll take the other side of that defeatist mindset any day of the week 🤫
Truly impressive achievement by James Litinsky with the $MP deal, showing incredible skill and success in the investment world.
Nothing—even remotely—matches the $MP deal James Litinsky pulled off: a return north of 100-300x. Absolutely incredible!
