If Marco Rubio defeats Kamala Harris in the 2028 presidential election, then the market resolves to Yes. This is a combination market requiring ALL specified outcomes to occur for the contract to pay out. If ANY single component resolves to No or becomes impossible, the entire contract immediately resolves to No. Each component is resolved according to its corresponding Kalshi ruleset: Democratic Nominee (PRESNOM), Republican Nominee (PRESNOM), Presidential Winner (PRESPERSON). All conditions must be satisfied the 2028 presidential election. This market will close and expire early if any component becomes impossible to occur (resolving to No) or all components have been satisfied (resolving to Yes).
