X banned in any European country by December 31?

This market will resolve to "Yes" if the use of X/Twitter is banned within any European country by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". For the purposes of this market, a “European country” is defined as any of the following sovereign states: Albania, Andorra, Austria, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Georgia, Germany, Greece, Hungary, Iceland, Ireland, Italy, Kosovo, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Moldova, Monaco, Montenegro, Netherlands, North Macedonia, Norway, Poland, Portugal, Romania, San Marino, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, Ukraine, United Kingdom, and Vatican City. A ban will qualify if legislation is enacted or government action is taken to bar the respective country's citizens from downloading and/or viewing X/Twitter, and/or posting on X/Twitter. Any legislation or government action that meets these standards will qualify, regardless of whether or when the ban goes into effect. The primary resolution source for this market will be official information from the respective government and X/Twitter; however, a consensus of credible reporting will 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.
