Icelandic European Union membership negotiations referendum passes?

The Icelandic European Union membership negotiations referendum is a ballot referendum in which voters will be asked whether Iceland should restart membership negotiations with the European Union. This referendum is currently scheduled to be held on August 29, 2026. You can find more information about the referendum here: https://government.is/topics/foreign-affairs/iceland-in-europe/referendum/. This market will resolve to "Yes" if Iceland passes this referendum. Otherwise, this market will resolve to "No". If the election is officially rescheduled to a date prior to December 31, 2026, 11:59 PM ET, the same rule applies to the new ballot and its corresponding deadlines. This market will resolve to "no" if no qualifying referendum vote is passed by December 31, 2026, 11:59 PM ET, or if such a referendum is scheduled to be held later than such date. The resolution source will be based on the official certified results of the vote as published by the National Electoral Commission of Iceland. Subsequent litigation, administrative challenges, or failure of any post-approval implementation steps will not be considered.

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.
