Nuclear weapon detonation in 2025?

This market will resolve to "Yes" if a nuclear weapon is detonated anywhere in the world between January 1 and December 31, 2025, 11:59 PM ET. Otherwise, this market will resolve to "No". For the purpose of this market's resolution, any detonation of a nuclear weapon anywhere on the planet Earth or in space will be sufficient to trigger a "Yes" resolution. This includes offensive usages, nuclear tests, and accidental detonations. Use/launch of a nuclear weapon that fails to detonate, a fake weapon that never detonates, or a dirty bomb that distributes radioactive material by means of a conventional explosion are not sufficient to trigger a "Yes" resolution of this market. Only a successful nuclear detonation will result in a "Yes" resolution. This market may resolve to "Yes" as soon as a nuclear detonation is confirmed by a preponderance of credible reporting. For the purpose of this market's resolution, determination as to whether a detonation was nuclear will be made by a preponderance of credible reporting.

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.
