On June 1, MP Materials rose 5.22% in regular trading, trading at $68.33/share, with trading volume of $166 million.

On the news front, the global rare earth market's tight supply-demand balance has further solidified, with spot prices of praseodymium-neodymium oxide maintaining elevated levels. Industry participants expect additional upside as Q3 procurement windows open. Although China's rare earth export control measures have been postponed until November, rigid domestic supply combined with accelerating downstream demand from electric vehicles and wind power continues to support the sector.

Additionally, MP Materials recently filed a lawsuit against competitor USA Rare Earth in Texas, alleging theft of its proprietary grain boundary diffusion formula — a technology developed over years and costing millions of dollars — highlighting the company's technical barriers in magnet R&D. Both companies are in critical capacity ramp-up phases as the U.S. pushes to build a domestic mine-to-magnet supply chain with federal funding support.

Within the Diversified Metals & Mining sector, USA Rare Earth Inc. rose 6.39%, CRITICAL METALS CORPORATION rose 6.7%, while HudBay Minerals fell 0.72%, Rio Tinto fell 0.21%, and BHP Billiton fell 0.02%.
