Can government stakes and price floors build U.S. rare-earth production?
Core argument: The Defense Department will take a 15% stake in MP Materials, America's largest rare earths miner, and commit billions of dollars to investing in the company and purchasing its output.
MP Materials America’s largest rare earths miner has reached a deal under which the Defense Department will take a 15% stake in the company. The government is committing to spending billions of dollars investing in MP Materials and purchasing its output. The deal calls for MP Materials to build a new factory to make rare-earth magnets at a scale that vastly exceeds current U.S. magnet production. It is expected to come online in 2028. In its deal with MP Materials, the Department of Defense is guaranteeing a price floor for rare earth minerals and magnets. That means the company is protected against a scenario in which China fully withdraws its restrictive export policies and the minerals flood into the market, lowering global prices.
