What to know

  • Status: Greenland is a self-governing part of the Kingdom of Denmark. The governments of Denmark and Greenland have repeatedly said it is not for sale.
  • Different deadlines: the Kalshi markets run to early 2029, while the Polymarket markets end in 2026, so their odds are not directly comparable.
