Pentagon’s $400M Stake in MP Materials: A Strategic Shift Toward Rare Earth Independence

Pentagon to become MP Materials' largest shareholder with a $400M investment, accelerating U.S. rare earth magnet independence amid China tensions.

Pentagon Bets Big on MP Materials to Secure U.S. Rare Earth Independence

In a bold move aimed at fortifying America's strategic supply chain, the U.S. Department of Defense is set to become the largest shareholder in MP Materials, the only rare earth mining company operating in the United States. The Pentagon will invest $400 million in preferred shares of MP Materials, the company announced on Thursday, leading to a surge of more than 60% in its stock price during premarket trading.

This landmark public-private partnership marks a decisive shift in the U.S. government's approach to securing critical mineral resources, particularly in the face of escalating geopolitical tensions with China—currently the world’s dominant supplier of rare earths.

MP Materials: America’s Lone Rare Earth Champion

MP Materials operates the Mountain Pass mine in California’s Mojave Desert, roughly 60 miles from Las Vegas. This site is the only functional rare earth mining and processing facility in the United States, making it central to the country’s ambition to reclaim dominance in rare earth production.

Rare earth elements—especially neodymium and praseodymium (NdPr)—are indispensable in manufacturing permanent magnets used in high-tech military equipment like the F-35 fighter jet, naval submarines, drones, and missile guidance systems. These magnets are also vital for commercial technologies such as wind turbines and electric vehicles.

Despite their critical role, the U.S. has been almost entirely reliant on foreign imports, with China providing over 70% of rare earths consumed in 2023, as reported by the U.S. Geological Survey.

What the Pentagon Investment Entails

The Pentagon’s investment strategy involves acquiring a newly issued class of preferred shares in MP Materials, which can be converted into common stock. It also includes a warrant to purchase additional common shares. Once fully converted and exercised, this would give the Defense Department approximately a 15% ownership stake, overtaking existing major stakeholders including MP CEO James Litinsky (8.61%) and BlackRock Fund Advisors (8.27%).

This infusion of capital will enable MP Materials to:

Expand processing capacity at its Mountain Pass mine
Establish a second U.S.-based magnet manufacturing facility, known as the 10X facility, with support from the Pentagon
Increase the company's rare earth magnet manufacturing capacity to 10,000 metric tons annually

The company expects the new facility to begin commissioning by 2028, and although the location remains undisclosed, its strategic significance is clear.

Securing the Supply Chain: Pricing Guarantees and Contracts

In an unprecedented move, the Defense Department has guaranteed 100% offtake of all magnets produced at the new 10X facility for a decade. This level of certainty provides MP Materials and its investors with strong visibility into long-term revenue streams.

Additionally, the Pentagon will set a price floor of $110 per kilogram for NdPr (neodymium-praseodymium) products, either stockpiled or sold. This pricing mechanism safeguards the company from market volatility and ensures long-term sustainability for the U.S. supply chain.

Private Capital Joins the National Security Mission

The partnership also includes significant financial backing from private sector giants:

JPMorgan and Goldman Sachs are contributing a combined $1 billion to help finance the new magnet manufacturing facility.
MP Materials is also set to receive a $150 million loan from the Pentagon to expand its rare earth separation capabilities at Mountain Pass.

The cooperation between government and private capital illustrates a rare and powerful alignment of interests aimed at reshaping a sector once dominated entirely by global competition.

A Geopolitical Imperative: Reducing Dependence on China

The move comes amid heightened concern over the U.S.’s strategic vulnerability to Chinese dominance in rare earth supply chains. Rare earths have often become a bargaining chip in broader U.S.-China trade and geopolitical disputes.

In April, Interior Secretary Doug Burgum confirmed that the Trump administration was exploring direct equity investments in critical mineral companies to reduce reliance on Chinese imports—a vision that has now come to fruition.

MP Materials CEO James Litinsky emphasized the long-term vision, calling the Pentagon’s stake a “public-private partnership” that will accelerate America’s supply chain independence.

“This initiative marks a decisive action by the Trump administration to accelerate American supply chain independence,” Litinsky noted.

What This Means for the Market and the Future

The announcement sent ripples through financial markets, with MP Materials stock soaring by more than 60% in the premarket session. Analysts believe this surge reflects not just investor enthusiasm over the deal’s financial implications, but also the broader shift in U.S. industrial policy toward onshoring strategic capabilities.

This is more than a corporate milestone—it’s a national security statement. By making direct equity investments in companies like MP Materials, the U.S. is signaling that critical mineral independence is no longer optional, but essential.

This move could also inspire a new wave of investments into domestic mining and manufacturing, especially as demand for EVs, renewable energy, and defense applications continues to grow.

Conclusion: The Future of Rare Earths is American

The Pentagon’s historic investment in MP Materials marks a significant step toward reclaiming U.S. leadership in rare earth production and reducing geopolitical risk. By securing domestic supply chains, the U.S. can better defend its technological edge, safeguard its military readiness, and insulate its economy from global disruptions.

With bipartisan support, robust financial backing, and a clearly defined strategy, MP Materials is no longer just a mining company—it’s now a cornerstone of America's future in advanced manufacturing and national defense.

Author’s Note:

As someone who closely follows the intersection of industrial policy and financial markets, I believe this development is a milestone not just for MP Materials, but for the U.S. economy’s long-term resilience. The collaboration between the Pentagon, Wall Street, and industry leaders like James Litinsky is a blueprint for how nations can align public and private interests to secure strategic independence in the 21st century. This story is a reminder that national strength begins with resource control—and the future is being forged beneath our feet.
