MP Materials stock news
On September 18, 2026, MP Materials (NYSE: MP) shares declined 2.35% to $48.22 following reports that the state--owned China Rare Earth Group is in negotiations to acquire Shenghe Resources. This transaction would grant the Chinese government an indirect 3% ownership stake in the primary U.S. rare earth producer. The potential deal introduces significant geopolitical complexity, as the U.S. Department of Defense is also a major stakeholder in MP Materials, which operates the strategically vital Mountain Pass mine in California.
