About this market
ContextThis market will resolve to "Yes" if the United States officially annexes any territory by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No." Annexation is defined as an official declaration or legal act by the US government claiming sovereignty over territory they were not claiming at the time of this market's creation. Qualifying examples of annexation include the Louisiana Purchase, however instances where settlers claim administrative control over land without a formal annexation will not count. The primary resolution source for this market will be official information from the US government; however, a consensus of credible reporting may also be used.
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.
