Traders assign overwhelming probability against Donald Trump acquiring Greenland before 2027 because the territory remains an autonomous part of Denmark, which has repeatedly rejected any sale since the 2019 proposal. Completing such a transfer would require sustained bilateral negotiations, a ratified treaty needing Senate supermajority support, congressional appropriations, and alignment with Danish parliamentary processes—all within roughly fourteen months. No recent diplomatic signals, legislative actions, or policy shifts indicate movement toward these steps. While improbable, late developments such as a sudden Danish government change, major economic concessions, or an unforeseen geopolitical crisis could theoretically reopen talks, though each faces steep structural and timeline barriers.
