Resolution rules
Each outcome is a separate contract with its own rules. The rules for Chuck Grassley:
If Chuck Grassley wins the nomination for the Republican Party to contest the 2028 Class III Iowa Senate seat, then the market resolves to Yes. The nominee is the winner of the June 2028 Iowa Republican primary. If no candidate receives at least 35% of the primary vote, the nominee selected by the Republican state convention counts.
