Polymarket runs a real-money market on this question. Norynta mirrors it with play credits: it opened at the Polymarket price and settles exactly as that market does. Players and a labelled market tracker move the price from there. Think the crowd is wrong? Trade against it.
This market will resolve to “No” if the United States takes a qualifying military action against Yemen by the specified date, 11:59 PM Yemen Standard Time. Otherwise this market will resolve to “Yes.” A qualifying military action refers to an air strike or a surface-to-surface missile strike, initiated by the United States, that directly impacts Yemen. An air strike includes bombs, air-to-surface missiles, and air-launched drones. A surface-to-surface missile strike includes one-way attack drones and surface-to-surface missiles such as cruise or ballistic missiles. The qualifying military action must be carried out by the armed forces of the United States. Actions carried out by private military contractors, mercenaries, or proxy forces will not qualify. Where a qualifying action is carried out in the course of a coalition or multinational operation, it will qualify only if the armed forces of the United States directly conducted the strike. The full rules are on the Polymarket market. Resolution: this play-money market resolves to the same result as the official Polymarket market settlement, linked as this market's resolution source.
