Recent developments in New Jersey’s 12 congressional districts show Democrats positioned to hold their nine seats from the prior cycle while targeting the Republican-held 7th, represented by incumbent Tom Kean Jr. Forecasters rate that contest as a toss-up or lean Democratic due to the district’s even partisan lean, Kean’s extended public absence earlier in the cycle, and the broader midterm environment viewed as a referendum on the Trump administration. National rating shifts have also strengthened Democratic holds such as the 9th, reducing the chance of losses. These dynamics drive trader consensus toward a net gain of one seat as the highest-probability outcome, with smaller probabilities attached to holding steady or achieving larger gains in less competitive districts.

All New Jersey 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. If the caucus decisions of relevant members of the US House of Representatives elected as independents cannot be determined as of the date of the 2026 United States midterm election, this market may remain open until the earlier of (i) an announcement from the relevant members of their intents to caucus, or (ii) January 4th, 11:59 PM ET of the following calendar year. If no such announcement is made by January 4th, 11:59 PM ET of the following calendar year, the member will not count towards the seat count of any party.
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.
