Why Antimony Supply Security Is Reshaping the Mining Sector—And Creating a Hot Commodity Play

The Strategic Resource Everyone’s Suddenly Concerned About

Semiconductors power artificial intelligence. Antimony powers semiconductors. And China controls the majority of global antimony supply—a problem that’s keeping Pentagon officials and tech executives up at night.

This critical mineral has become one of the most important commodities on the planet, yet most investors haven’t noticed the seismic shift happening in the sector. China and Russia command over 60% of global antimony ore production, making them gatekeepers to a resource that’s fundamental to AI infrastructure and national defense. When Beijing threatened export bans on antimony last year, it sent shockwaves through supply chains worldwide.

The threat hasn’t fully materialized, but significant restrictions remain in place. The uncertainty is forcing the U.S. government and major tech companies to seek alternative sources—and they’re not interested in waiting years for new suppliers to ramp up production.

U.S. Antimony’s Uncommon Market Position

Enter U.S. Antimony (NYSEMKT: UAMY)—the only antimony producer operating in North America. This distinction alone sets the company apart in a market starved for domestic supply.

The stock has demonstrated remarkable momentum, gaining approximately 900% over five years and rising around 190% through 2025. With a market capitalization near $730 million, it remains small enough to move significantly in either direction. Investors should anticipate volatility; this is not a stable, utility-like investment.

What makes U.S. Antimony’s position particularly compelling is the absence of real domestic competition. International competitors like Perpetua Resources are still years away from commercial production. Meanwhile, U.S. government agencies and artificial intelligence companies need antimony now, not in 2027 or 2028. They’re prepared to pay premiums for immediate access.

Explosive Revenue Growth Backed by Government Demand

The numbers tell a striking story. U.S. Antimony projects $40 million to $43 million in 2025 revenue, representing 182% year-over-year growth through the first nine months. Third-quarter revenue more than tripled compared to the prior year. Looking ahead, the company anticipates reaching $125 million in revenue during 2026—nearly triple the 2025 forecast.

“Most of our potential competitors discuss plans for two to four years down the road,” said Joe Bardswich, Executive Vice President and Chief Mining Engineer. “We’re extracting ore and selling finished products to customers today.”

This isn’t hyperbole. The Pentagon awarded U.S. Antimony a $245 million contract to replenish the National Defense Stockpile, plus an additional $10 million delivery order from the Department of Defense. These aren’t speculative contracts—they’re immediate capital commitments from the world’s largest military power.

A Hot Commodity With Multiple Tailwinds

Rising antimony prices create a powerful tailwind for both revenue and profitability. Higher commodity prices flow directly to the bottom line while the company maintains near-monopoly pricing power in North America. Should China escalate restrictions further, the U.S. government faces limited options but to increase its investments in domestic production.

U.S. Antimony operates two antimony smelting facilities in Montana and Mexico, making it the only Pentagon-approved fully integrated antimony miner and refiner in North America. The company is expanding with new mining claims in Alaska and the Sudbury Basin in Ontario. It also controls a zeolite mine in Idaho—another critical mineral for nuclear remediation and potentially important for tech companies pivoting toward nuclear power.

The Verdict

U.S. Antimony occupies a rare position: a hot commodity producer with government backing, first-mover advantage, and genuine supply-chain urgency working in its favor. It’s a small-cap stock that could experience significant appreciation, though volatility will be a constant companion.

The combination of geopolitical necessity, immediate government demand, and near-exclusive North American supply creates compelling fundamentals for a contrarian bet on antimony’s critical role in both AI infrastructure and national security.
