The market is conditional on a nuclear weapon being launched for combat, non-testing purposes before Jan 1st, 2023, anywhere in the world (referred to as CONDITION).

It resolves to N/A if CONDITION isn't met.

It resolves to YES if the original nuclear weapon launched for combat is a Russian attack, targeting Ukrainian territory (in 2022). If many nuclear weapons are launched at the same time (within an hour), it resolves to YES if any are targeting Ukrainian territory. If the launched weapon fails to detonate, it still counts as YES.

It resolves to NO if CONDITION is met, but the weapon launched doesn't target Ukrainian territory or isn't Russian.
