Shares in a number of Greenland-linked companies have surged after US President Donald Trump renewed threats to take control of the Danish territory, fuelling speculation around potential US involvement and investment in the resource-rich island.

According to reporting by the Financial Times, Copenhagen-listed Grønlandsbanken, Greenland’s largest bank, has risen around 33% this week following Trump’s repeated assertions that the United States must “have” Greenland.

Other companies with exposure to the territory have also seen sharp gains. US-listed Critical Metals, which is exploring for rare metals in southern Greenland, has climbed more than 100% since the start of the year. Føroya Banki, a Nordic lender with operations in Greenland, has reached an all-time high after gaining roughly 30% since mid-November.

The rally has coincided with increasingly aggressive rhetoric from the Trump administration, including suggestions that military force could be used to secure control of the island, which is home to about 57,000 people and holds significant natural resource potential. The comments have drawn strong objections from Denmark and European Union officials.

While no formal policy steps have been announced, the market moves suggest investors are positioning for scenarios in which increased US involvement could lead to higher investment, particularly in Greenland’s financial and resource sectors.

The surge also reflects broader market sensitivity to geopolitical headlines, especially where strategic assets and natural resources are concerned. Recent developments elsewhere, including US actions in Venezuela, have similarly triggered speculative interest in companies seen as exposed to potential shifts in foreign policy.

For now, Greenland-linked stocks appear to be benefiting from heightened attention and uncertainty, highlighting how geopolitical signals alone can drive significant short-term market movements.
