America’s Rare Earth Clock Is Running Out, But the Bottleneck Isn’t Where You Think

Key Points

• A January 1, 2027 defense sourcing deadline bars Chinese-origin rare earth metals and magnets from U.S. defense systems, while domestic magnet output covers roughly 1% of demand.
• REalloys plans to begin producing rare earth metals in early 2027 and heavy rare earths by year-end, with a planned facility at Utah's Tooele Army Depot still under a term sheet.
• MP Materials remains the main U.S. midstream processor of light rare earths, while REalloys argues its feedstock-agnostic model and near-term production timeline set it apart.

Election headlines are dominating the tape, but the date that matters most for defense and critical minerals investors isn’t on any ballot. On Jan. 1, 2027, a Pentagon sourcing rule bars Chinese-origin rare earth metals and magnets from U.S. defense systems, and the support behind it runs across both parties.

That puts a hard edge on a supply chain the United States handed to China decades ago. Fighter jets, submarines, and missiles all run on rare earth magnets, and China controls the overwhelming majority of global production. The deadline itself may already be in the price. The open question is who can actually deliver domestic metal once stockpiles run thin.

A 2027 Defense Sourcing Deadline Exposes a 99% Domestic Supply Gap

Anupam Ghildyal, chief operating officer of REalloys NASDAQ: ALOY, frames the stakes bluntly. Under the Defense Federal Acquisition Regulation Supplement (DFARS), metals from China or other embargoed countries can’t go into U.S. defense systems after the deadline. In his reading, that means no F-35, submarine, or aircraft carrier built with Chinese-origin metals or magnets.

China makes more than 90% of light rare earths, 97% of heavy rare earths, and more than 90% of magnets, per Ghildyal. U.S. magnet demand runs about 50,000 tons a year against roughly 500 tons of domestic output in 2026, or about 1%.

Defense contractors have been stockpiling, which could cover a few months. After that, he expects a genuine shortage.

Politics isn’t the swing factor, in his view. Washington has issued near-monthly reminders that the date is real, and reliance on an adversary for defense inputs worries both parties. If the deadline slips, it would likely be because domestic capacity isn’t ready—not because of an election.

Processing, Not Mining, Is the Real Rare Earth Bottleneck

Rare earths aren’t rare. Processing them is.

REalloys has its own mine, but its focus is the midstream: stripping contaminants, separating oxides, and converting them to metal. That stage is nearly empty in the United States. MP Materials NYSE: MP processes significant volumes of light rare earths but, to Ghildyal’s knowledge, no heavy rare earths. Domestic heavy rare earth output, he says, is zero.

It’s an argument he has made before, and the case for processing as the real 2027 chokepoint has only sharpened since. REalloys also pitches itself as feedstock-agnostic. Many developers build processing around a single ore, such as bastnaesite or monazite, so their plants can only run their own rock. REalloys says it can handle multiple types, which widens the pool of suppliers it can pull from instead of leaning on one deposit.

Rebuilding the chain is a seven- to 10-year project, per Ghildyal, because the United States outsourced processing in the 1980s and early 1990s while China spent 40 years scaling and innovating. Even with unlimited money, permits and power push a new facility out at least a couple of years.

An Army Base Partnership Could Fast-Track Heavy Rare Earth Supply

The U.S. Army selected REalloys to build rare earth metal manufacturing at Tooele Army Depot in Utah, per Ghildyal. The site would start with heavy rare earth metallization and could later add magnets.

Phase 2 is planned at roughly six times Phase 1, targeting about 3,500 tons a year of rare earth metals and 3,000 tons of magnets, with the Army holding a right of first offer on output. Those terms remain in a term sheet, and definitive agreements haven’t been signed.

REalloys plans to start producing rare earth metals in the first quarter of 2027 and add heavy rare earths by year-end. Its long-range goal is 20,000 tons of magnets a year, which it estimates would cover 20% to 40% of U.S. magnet demand in 2035.

Production Revenue, Not Budget Headlines, Could Reprice Rare Earth Stocks

Rare earth and drone stocks have lagged amid defense budget delays in Congress. Ghildyal shrugs off that link. Defense spending tends to rise over time, and the contractors building those jets, submarines, and missiles still need the hardware regardless of when a budget clears.

The sector’s real problem is revenue. Rare earth names have made plenty of noise, but only one or two U.S.-listed companies generate sales, per Ghildyal. He expects that to change quickly as producers come online, and demand doesn’t look like the constraint. Customers are asking for small lots of dysprosium and yttrium, and he believes domestic output could sell within hours, while conceding there are no guarantees.

Capital may be less of a hurdle than it looks. Ghildyal estimates 20,000 tons of annual magnet capacity would take a couple of billion dollars in capital expenditures (CapEx) and could support $6 billion to $8 billion in revenue. Government loans, guarantees, and price floors cushion producers if China pushes prices lower. REalloys says it funded Phase 1 with equity alone and plans to seek Phase 2 financing once revenue starts.

The upside is a company that could be generating revenue while many peers point to 2029 or 2030 start dates. The risk is execution, since permits, ramp-ups, unsigned agreements, and price swings could all push those dates out.

Domestic Output Milestones Matter More Than the January Date

Ghildyal thinks the deadline is already baked into defense and supplier stocks, so Jan. 1 alone may not be the spark. Where analysts have set their targets reflects that same wait-for-production stance. He also warns this isn’t a sector for quick doubles, framing reshoring as a long-term trend that doesn’t reverse.

MP Materials is the light rare earth processing base the United States already has. REalloys is a bid to add heavy rare earths and flexible processing on a secure defense site. Both answer the question the market keeps asking, which is who can make the metal here.

The setup doesn’t depend on the deadline holding to the day or on a bigger defense budget. It does depend on production arriving on schedule, the Army agreements being finalized, and price support holding if China leans on the market.

Stay focused on first production and signed supply agreements, because that’s what moves rare earth stocks from promise to revenue.
