The winner of each race is determined including any runoff or other relevant procedure under the applicable rules of the relevant jurisdiction. Seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation, or vacates their office, after election day, the seat is attributed to the party under which the person was elected. Candidates who run as independents or third-party candidates will not be considered to be Republicans regardless of affiliation or caucus decisions. In the event that the winner of an election cannot be determined by March 31, 2027, that election will not be considered for purposes of this market. The resolution sources for this market will be official information from relevant state electoral authorities, the United States Congress, and a consensus of credible reporting.
