Rules

This market is scheduled to end November 03, 2026, 11:59 PM ET.

This market will resolve according to the number of seats in the US House of Representatives won by the Democratic Party in California in the 2026 United States midterm election. All California US House of Representatives elections held as part of the 2026 United States midterm election that elect voting members and determine representation in the upcoming 120th congress are included. Special elections to fill a vacancy for the remainder of an unexpired term are not included, whether or not held concurrently with the 2026 United States midterm election. Runoffs for qualifying elections will determine attribution of the relevant seat. Seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation or vacates their seat after the date of the 2026 United States midterm election, the seat is attributed to the party under which the member was elected. Members of the House elected as independents who formally caucus, or who announce their intent to caucus, with a party prior to the date of the 2026 United States midterm election are included in that party’s count. … (condensed)
