Results for the 435 House races contested in 2018. Prior to the election, Republicans held 235 seats, Democrats 193. There were seven vacancies.
Democrats won control of the chamber in the 2018 midterm elections, with a net gain of 40 seats. One race remains undecided on the map. The GOP won a close race in NC-9, but credible accusations of election fraud mean a new election is likely in 2019. Assuming that is the case, Democrats will hold a 235-199 advantage - with one vacancy - when the new Congress is seated in January.
