Rare Earth Metals and the Escalating U.S.-China Trade Tensions
Rare earth metals, the raw materials that power modern technologies such as chips, EV engines, and military weapons, are at the center of the escalating U.S.-China trade tensions. As the Trump administration pushes to reduce reliance on imports from China, which produces more than 90 percent of the world’s supply, investors are betting big on MP Materials, the only U.S.-based company that mines, refines, and processes rare earths. The company’s stock has surged more than 400 percent this year, raising concerns about whether its valuation is entering bubble territory.

Why MP Materials is the Sole Metal Producer in the U.S.
MP Materials operates in California’s San Bernardino Valley, sitting atop a rich ore deposit at the Mountain Pass mine. Its core product, neodymium-praseodymium (NdPr) oxide, is processed at its Fort Worth, Texas facility into neodymium magnets, known as NdFeB magnets. These magnets are essential components in electronics, EVs, robotics, aerospace, and defense systems due to their high magnetic strength and energy density. As the U.S. seeks to reduce its dependence on China, MP offers a strategic advantage, challenging China’s near-total dominance of the global metals market amid the Trump administration’s push to revive domestic manufacturing.
Building new U.S. mines is notoriously difficult due to complex permitting rules, environmental regulations, high capital costs, and long development timelines. MP sidestepped many of these obstacles by reviving an existing mine that already had much of the needed infrastructure and approvals in place. According to Steve Christensen, executive director of the nonprofit Responsible Battery Coalition, “The lengthy permitting processes and overly complex regulations in the U.S. have made domestic extraction and processing of rare earths very expensive, placing U.S. development at a severe disadvantage compared to global competitors.”
Is MP Materials in a Bubble?
Despite concerns, most analysts agree that MP is unlikely to enter bubble territory in the short term. China’s export restrictions, combined with deregulation under the Trump administration and strong government partnerships, have positioned MP as a key player in America’s effort to decouple its tech supply chain from China. Mark MacDonald, vice president of investor relations at Ucore Rare Metals, notes that “This government commitment will provide excellent long-term financial opportunities as this new industry is established and MP is the de facto leader of this movement.”

However, MP’s long-term value hinges on its ability to scale production. The company recently opened a magnet facility in Fort Worth, Texas, which began commercial production in January 2025—part of a broader plan to establish a U.S. rare earth-to-magnet supply chain by 2026. MP aims to produce 1,000 metric tons of magnets annually, supplying three of the five major automakers, including General Motors, according to the company. To justify its valuation, MP must prove it can expand output efficiently.
As Diana Rasner, group lead of the materials, chemicals, waste, and recycling division at CleanTech Group, a business intelligence firm, notes, “There’s a lot of promise for this to actually bring the control of the supply chain home, but it hasn’t been proven out at scale yet.” Rasner cautions against putting all hopes on one company, as overreliance on MP could sideline smaller players in the U.S. tech supply chain and new rare earth producers that could emerge under the Trump administration.
