Why Antimony Supply Dynamics Are Reshaping U.S. Defense and Technology Strategies

The Strategic Importance of Antimony in Modern Supply Chains

Antimony has quietly emerged as one of the most consequential materials for national security and technological advancement. As a critical component in semiconductor manufacturing, this element sits at the foundation of artificial intelligence infrastructure and military applications. Yet most investors remain unaware of its growing geopolitical significance.

The supply chain vulnerability stems from a stark reality: China controls the majority of global antimony export capacity alongside Russia, commanding over 60% of worldwide antimony ore production. When Beijing began signaling potential export restrictions—and briefly threatened an outright ban—it triggered urgent action across U.S. government agencies and technology companies. The threat has since been tempered, but substantial export controls remain in place, creating persistent uncertainty about future access.

A Monopoly Opportunity in North America

This geopolitical pressure has created an unusual market dynamic. While multiple antimony producers operate internationally, North America has essentially one active supplier: U.S. Antimony (NYSEMKT: UAMY). Other potential competitors, including firms like Perpetua Resources, remain years away from commercial production. This timing mismatch works decisively in U.S. Antimony’s favor.

The Pentagon and artificial intelligence companies cannot afford to wait. Both require immediate, reliable access to antimony supplies at scale. U.S. Antimony has capitalized on this urgency, translating it into rapid expansion. The company projects 2025 revenue between $40 million and $43 million, representing 182% year-over-year growth through the first nine months of 2025. Even more striking, Q3 revenue tripled compared to the prior year period.

Looking ahead, management forecasts revenue could climb to $125 million in 2026—a near 200% increase from the midpoint of 2025 guidance. The company operates two antimony smelting facilities spanning Montana and Mexico, holding the distinction of being the sole DOD-approved fully integrated antimony miner and producer across North America.

Government Backing as a Competitive Moat

U.S. Antimony’s market position strengthened considerably after securing a $245 million Pentagon contract to replenish the U.S. National Defense Stockpile, complemented by a $10 million delivery order from the Department of Defense. These agreements underscore how essential government entities view antimony access and demonstrate the financial commitment Washington will deploy to reduce supply chain risk.

Should China escalate export restrictions further, the U.S. government faces limited alternatives. The logical response would involve increased capital commitments to domestic production capacity. This dynamic creates a structural advantage for U.S. Antimony—the company functions as infrastructure for both defense and technology sectors.

The stock itself has attracted significant market attention, climbing more than 900% over the past five years and advancing approximately 190% during 2025. However, the company maintains a relatively modest market capitalization near $730 million, suggesting potential room for expansion. Investors should note the stock exhibits substantial volatility, characteristic of emerging supply-critical mining companies.

Territorial Expansion and Diversification

Management continues extending the company’s footprint beyond current antimony operations. Mining claims in Alaska and Ontario’s Sudbury Basin represent future production capacity. Additionally, U.S. Antimony operates a zeolite mine in Idaho—a material with applications in nuclear remediation and potentially relevant to tech companies pursuing nuclear power infrastructure for data centers and AI operations.

The convergence of antimony demand, geopolitical supply constraints, and government support has fundamentally altered the competitive landscape for critical minerals in North America. U.S. Antimony occupies the sole position to serve this demand today, a distinction that carries substantial strategic and commercial implications for the evolving technology and defense sectors.
