USA Rare Earth shares rose 8.52% to $16.68 after President Donald Trump announced a new U.S. security agreement with Denmark and Greenland. The agreement includes plans to expand U.S. military deployment, restrict sensitive investments by adversaries without U.S. approval and establish what Trump described as "permanent control" over Greenland's security affairs. It is expected to be finalized during the United Nations General Assembly. The announcement lifted Greenland-focused mining and rare-earth stocks, including Critical Metals Corp., which owns a 92.5% stake in Greenland's Tanbreez rare-earth project and gained roughly 25%. USA Rare Earth has no assets in Greenland; its holdings span the United States, United Kingdom, France and Brazil, including the Round Top deposit in Texas and magnet manufacturing operations in Stillwater, Oklahoma. Its gain reflects a thematic sympathy trade tied to broader rare-earth sector momentum and renewed efforts to secure Western supply chains outside China, according to 24/7 Wall St.
