Critical Metals Stock Surges on Greenland Security Pact

Shares of Critical Metals surged on Monday, September 21, 2026, following the announcement of a trilateral security pact between the United States, Denmark, and Greenland. The stock climbed approximately 25% to 37.5% during the trading session, with prices reported between $8.41 and $9.22. The rally was fueled by investor optimism that the agreement could enhance Western access to Greenland's mineral resources, particularly the Tanbreez rare earth deposit. Critical Metals owns a 92.5% stake in Tanbreez, which it describes as one of the world's largest undeveloped heavy rare earth deposits and the only project in Greenland with an exploitation permit for rare earths. President Donald Trump announced the deal on Friday, September 18, in a post on Truth Social, stating the U.S. had reached an agreement granting it permanent control over Greenland's security. "At my direction, we worked with representatives of Denmark and Greenland to guarantee that the United States will FOREVER have the complete ability to do what is necessary in Greenland to secure and defend the security of Greenland, and the United States of America," Trump stated.
