If the Republican party wins the majority in both the House and Senate, and also secures the presidency, then the market resolves to Yes. A party controls its chamber if they win a majority of voting seats or have more than half of the voting members. The resolution source for this market is the Associated Press, Fox News, and NBC, and it will resolve once all three sources conclusively call winners in the House, Senate, and Presidency. If control of either chamber is ambiguous due to ongoing special elections or runoff triggers, the market will resolve according to party affiliation at the time of the official certification.
