We need permission from the Chinese government to make military things.
Beneath the Mojave Desert lies a quiet battleground where geology meets geopolitics. The United States, long dependent on China's near-total dominance of rare earth magnet production, has placed a $400 million bet on a single California mine and two unlikely stewards to reclaim a supply chain essential to fighter jets, smartphones, and the machinery of modern life. The Pentagon's investment in MP Materials — including a government ownership stake and a decade-long price guarantee — reflects a reckoning with how deeply strategic vulnerability can be hidden inside everyday commerce. Whether this act of industrial will arrives in time remains an open question, as a fragile trade truce with Beijing approaches its expiration.
- China's grip on over 90% of rare earth magnet production became undeniable in 2025 when retaliatory export restrictions left Ford and other manufacturers scrambling for materials they didn't know they lacked.
- The crisis exposed a supply chain so hollowed out that America's defense systems — from F-35 jets to drone fleets — effectively required Beijing's cooperation to function.
- The Pentagon responded with rare urgency, invoking the Manhattan Project and Operation Warp Speed as it injected $400 million into MP Materials and took a 15% ownership stake in the nation's only active rare earth mine.
- A 10-year price floor shields the company from China's historic tactic of flooding markets to undercut competitors, but the demand is steep: tenfold growth in magnet production by 2028.
- A second magnet factory is rising in Texas, refined powder worth $120,000 a bag is destined for GM and Apple, and Mountain Pass now employs over 700 — yet China still dominates, and the trade truce expires in November.
In the Mojave Desert, an open pit mine 600 feet deep has become an unlikely symbol of American strategic anxiety. Mountain Pass, California — the country's only active rare earth mine — sits at the center of a quiet crisis: the United States has allowed China to control more than 90 percent of the rare earth magnet production that powers its weapons, vehicles, and consumer electronics.
Two Florida hedge fund managers, James Litinsky and Michael Rosenthal, bought the bankrupt Mountain Pass operation in 2017 and found it literally flooded — 30 million gallons of water, eight employees, and years of work ahead. They rebuilt it from the ground up, mastering the difficult chemistry of refining rare earths to industrial purity and eventually completing a full supply chain with a magnet factory in Fort Worth, Texas.
The urgency sharpened in spring 2025, when U.S. tariffs prompted China to restrict rare earth exports. Manufacturers discovered, suddenly and painfully, how exposed they were. Ford lacked magnets. Defense contractors faced shortages. Washington could no longer look away.
The Pentagon summoned Litinsky and Rosenthal and made its expectations clear. The resulting deal was unusual by any measure: $400 million in government investment, a 15 percent ownership stake for American taxpayers, and a guaranteed 10-year price floor — protection against China's long-practiced strategy of undercutting competitors until domestic production becomes economically impossible. In exchange, MP Materials must increase magnet output tenfold by 2028.
A second, larger Texas factory is now under construction. Mountain Pass employs more than 700 people, and its refined rare earth powder — each bag valued at roughly $120,000 — will soon flow into General Motors vehicles and Apple products. Officials defended the government's equity position not as a departure from free markets, but as a response to a market that an adversary had already broken.
Still, the work is unfinished. China retains its dominance in global production, and the U.S.-China trade truce that has kept supplies flowing is set to expire in November. The mine in the Mojave is producing again, but America's industrial independence remains, for now, a work in progress.
In the Mojave Desert, an hour southwest of Las Vegas, a massive open pit cuts 600 feet into the earth. This is Mountain Pass, California—the only active rare earth mine in the United States, and increasingly, the front line of America's struggle to break free from Chinese control over materials essential to modern warfare and everyday life. Two hedge fund managers from Florida, James Litinsky and Michael Rosenthal, now run this unlikely fortress. Neither has a background in geology or mining. Yet they find themselves at the center of a national security crisis that few Americans know exists.
Rare earths are not actually rare. What is scarce are deposits rich enough and accessible enough to mine profitably. These elements—seventeen metals buried deep in the periodic table—possess magnetic, conductive, and optical properties that make them indispensable. A single F-35 fighter jet contains roughly 100 pounds of rare earths woven throughout its systems. Your smartphone, your car, your laptop: all depend on them. So do drones, radar systems, and electric vehicles. For decades, this supply chain was entirely controlled by China, which gradually cornered the market by undercutting competitors until American mining became economically impossible. By the time the Trump administration took office, China controlled more than 90 percent of rare earth magnet production globally.
The vulnerability became catastrophic in the spring of 2025. After the administration imposed sweeping tariffs, China retaliated by choking off rare earth exports. Ford Motors suddenly lacked magnets for production. Major manufacturers discovered, to their horror, that they had no idea how dependent their supply chains were on Chinese rare earths. The economy teetered on the edge of shutdown. It took a crisis to force Washington to act.
Litinsky and Rosenthal had already begun rebuilding Mountain Pass after buying the bankrupt Molycorp operation in 2017. The mine was literally underwater—30 million gallons of water pooled at the bottom, with only eight employees on staff. They invested hundreds of millions of dollars to restart extraction and, crucially, to master the difficult chemistry of refining rare earths to 99.9 percent purity. Three years of work yielded the ability to produce neodymium and praseodymium at industrial scale. By 2024, they had built a magnet factory in Fort Worth, Texas, completing the supply chain from mine to finished product. But they needed more capital and faster growth than the market alone could provide.
The Pentagon called them to Washington with an explicit directive: accelerate. Officials used two phrases—Manhattan Project and Operation Warp Speed—to describe what they wanted. The result was an unusual deal that blurred the line between capitalism and industrial policy. The Pentagon injected $400 million into MP Materials and took a 15 percent ownership stake, making American taxpayers part-owners of a rare earth company. More critically, the government guaranteed a 10-year price floor, protecting MP from China's traditional weapon of market flooding. The deal came with one non-negotiable demand: increase rare earth magnet production tenfold by 2028.
MP is now building a second, larger magnet factory in Texas to meet that target. Today, the Mountain Pass operation employs more than 700 people. The refined rare earth powder—each bag worth around $120,000—will flow into General Motors vehicles and Apple products starting next year. Yet even with these investments, China still dominates global magnet production. The vulnerability persists. Secretary of the Interior Doug Burgum defended the government's equity stake and price guarantees as pragmatism rather than socialism, arguing that free markets cannot function when an adversary controls a monopoly. The U.S.-China trade truce is set to expire in November. Without renewal, the rare earth supply remains exposed, despite the progress at Mountain Pass. For now, America's defense industrial base still requires permission from Beijing to function.

Why does a metal buried in the ground matter so much to national security?
Because every advanced weapon system we have depends on rare earths. An F-35 carries 100 pounds of them. Without these elements, you can't make the magnets that power modern electronics—from missiles to radars to fighter jets. China realized this decades ago and built a monopoly. Now we can't make military equipment without their permission.
But the U.S. used to mine rare earths. What happened?
Economics. China could do it cheaper, so American companies shut down. Mountain Pass closed in the 1990s after environmental problems and couldn't compete. For thirty years, we outsourced the entire supply chain. It seemed rational at the time. It wasn't.
Two hedge fund guys buying a mine seems absurd. How did they even know what to do?
They didn't. Litinsky saw the assets—this massive pit with one of the world's richest deposits—and recognized the value. Rosenthal learned mining and metallurgy on the job. They had capital and determination. Sometimes that's enough. But they couldn't have scaled without government backing.
So the Pentagon is now part-owner of a private company. Isn't that socialism?
That's what the interviewer asked Burgum. He said it's pragmatism, not socialism. When your adversary controls a monopoly, free markets don't work. You need to kick-start domestic capacity. It's the same logic that built the railroads and the semiconductor industry.
Can MP Materials actually break China's hold?
Not yet. China still makes over 90 percent of the world's rare earth magnets. MP's new factory won't be ready until 2028. Even then, it will only meet U.S. needs. The real risk is what happens if China decides to weaponize this again—say, during a conflict over Taiwan. We'd still be dependent.
What's the deadline?
November. The trade truce expires then. If there's no new deal, China could cut off rare earths again. By then, MP will have more capacity, but not enough to fully replace Chinese supply. We're in a race against time.
