Several states completed mid-decade congressional redistricting between summer 2025 and mid-2026, producing new maps expected to govern the 2026 House elections. Ten states—Alabama, California, Florida, Louisiana, Missouri, North Carolina, Ohio, Tennessee, Texas, and Utah—enacted or had court-approved changes, often following the Supreme Court’s Louisiana v. Callais ruling that altered standards for race-based districting and prompted further litigation and legislative action. These revisions, driven by state legislatures and ballot measures, account for the market’s strong consensus on those states. A smaller number of additional states attempted but failed to finalize new lines before primary deadlines, while most others remain on post-2020 maps. Special primaries and final court rulings in August 2026 represent the last procedural checkpoints that could still affect a handful of districts.
