Will Alberta join the US?

This market will resolve to "Yes" if it is officially announced that Alberta will come under US sovereignty, or if Alberta officially comes under US sovereignty, by December 31, 2026, 11:59 PM ET. Otherwise this market will resolve to "No". Sovereignty is defined as the transfer of the majority of the territory of Alberta as of February 6, 2026, currently a Canadian province, to being under the formal governance or jurisdiction of the United States, either as a state, territory, or other classification within the US system. An official announcement made by the United States and Canada that Alberta will come under US sovereignty, within this market's timeframe, will qualify, even if the actual transfer of sovereignty is yet to occur. Only announcements of official agreements or actions (e.g. a ratified treaty, signed legislation, etc.) will count - mere suggestions, negotiations, or posts on Social Media will not. The resolution source for this market will be official information from the governments of the US, Canada, and Alberta, however a consensus of credible reporting confirming that Alberta has come under U.S. sovereignty will also qualify.

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders at your target price. All positions are settled in USDC when the market resolves.

Resolution

Markets resolve through UMA's Optimistic Oracle. After the market closes, a proposer submits a resolution, followed by a 2-hour dispute window. If no dispute is raised, the resolution is accepted. Disputed markets go to UMA token holder vote.
