Starting with Texas in the summer of 2025, a series of states redrew their US House districts in the middle of the decade, and other states answered with maps of their own or declined to act. Courts decided much of the outcome, including the US Supreme Court's ruling in Louisiana v. Callais on 29 April 2026, after which Florida, Tennessee and Louisiana adopted new maps in May. Missouri's 2025 map was suspended pending a citizen referendum, and the state votes under its 2022 districts on 3 November 2026.
Nine states use new House districts on 3 November 2026, the Associated Press reported in September: Alabama, California, Florida, Louisiana, North Carolina, Ohio, Tennessee, Texas and Utah. Louisiana holds an open House primary under its May 2026 map, with a 12 December election where no candidate wins a majority. Missouri votes under its 2022 districts, with a referendum on the 2025 map on the same ballot. Virginia, Indiana, South Carolina, Maryland and New York use their existing maps, and Maryland voters also decide an amendment on congressional districting that would not change the 2026 map, the Maryland Association of Counties and NCSL reported.
