Rare earth-related stocks advanced on Tuesday, with Critical Metals (CRML.US) and USA Rare Earth (USAR.US) climbing more than 7%, while MP Materials (MP.US) and Energy Fuels (UUUU.US) rose over 3%. The upward movement followed reports that the Trump administration plans to leverage an artificial intelligence program developed by the U.S. Department of Defense to help establish reference prices for critical minerals as part of efforts to build a global metals trading group. These reference prices will be determined by the Department of Defense's AI-driven "Security Open Price Exploration" (OPEN) metals initiative. According to sources, Trump administration officials are initially focusing the OPEN pricing model on at least four key minerals—germanium, gallium, antimony, and tungsten—with plans to expand to other minerals in the future.
