Ukraine responsible for Moscow attack?

This market will resolve to 'Yes' if the March 22 attack at Crocus City Hall is officially attributed to a Ukrainian group by March 31, 2024, 11:59 PM ET. ‘Ukrainian group’ will be considered any group which primarily consists of Ukrainians, or is otherwise affiliated with the government of Ukraine. This market may resolve once it is definitively determined whether or not the attack was attributed to a Ukrainian group. The primary resolution source for this market will be official information from the Russian and Ukrainian governments and security services. 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.
