The Pentagon just made one of its biggest strategic investments in U.S. mining in recent history, and it’s worth a closer look for investors.
In a bold move to secure America’s supply of rare earth elements, the Department of Defense purchased a 15% equity stake in MP Materials (MP) — the only major rare earth mining company operating in the U.S. The deal includes a staggering $400 million in stock, plus a $150 million government loan.

So what’s going on here?
Rare Earths Are the New Gold Rush
Rare earth elements are essential to powering everything from:
- iPhones and EVs
- Drones and military jets
- Missile guidance systems and nuclear submarines
And 90% of the world’s rare earths? They come from China — the very country the U.S. is competing with in the global artificial intelligence (AI) and defense race.
That’s why this investment in MP stock isn’t just a mining play. It’s a national security move.
What Do They Know That You Don’t?
The U.S. Department of Defense plans to continue investing in critical minerals projects to ensure a domestic supply for weapons and many electronics.
Just 6 miles north of MP’s Mountain Pass mine lies a tiny, overlooked project run by Dateline Resources (DTREF), a microcap mining stock with both gold and rare earth exposure at its Colosseum project. Some analysts believe it may be geologically identical to MP’s massive mine — a “carbon copy,” in the words of insiders.
And with China recently hiking rare earth prices by 14%, retail traders and hedge funds are starting to take notice.
Apple’s $500 Million Bet
Apple (AAPL) also just inked a $500 million deal with MP Materials to secure its rare earth pipeline — making this not just a government-backed investment, but a corporate supply chain priority, too.
The Department of Defense has even introduced a price floor of $110/kg on rare earths, which could practically guarantee profits for approved suppliers.

Final Thought
The Pentagon doesn’t usually buy stock. When they do — especially in a critical industry — it’s time to pay attention.
Rare earths might not just power the next generation of defense tech… They could power your next winning trade, too.
