President Trump’s security agreement with Denmark and Greenland is expected to be signed this week, easing months of U.S. pressure over the semiautonomous Danish territory and potentially opening the way for greater American investment. Greenlandic and U.S. businesspeople say the accord could reduce geopolitical tension, encourage development on the resource-rich but cash-starved island and lessen the stigma Greenlanders associate with working with Americans. The agreement would expand U.S. military access and allow Washington to bar particular parties, potentially including Chinese or Russian interests, from Greenland’s critical-minerals and mining sectors, while sovereignty remains with Denmark. Greenland’s parliament and Denmark’s parliament must approve the arrangement. The territory has substantial rare-earth resources, but harsh conditions, an ice sheet covering 80% of its land and limited infrastructure make development costly. Prediction-market odds of signing by September 23 rose to 74.5% from 64% over 24 hours, while the probability of a broader U.S. acquisition by the end of 2026 remained 5.9%.
