75% of Kalshi traders now back Democrats to win the House, down from 85.3% on April 28 and the party's lowest odds since late December.
Two court decisions drove the drop: the U.S. Supreme Court's April 29 Louisiana ruling curbed race-based mapmaking, and Virginia's top court voided a voter-approved redistricting referendum.
Louisiana is expected to send one fewer Democrat to Congress, while Tennessee, Alabama and South Carolina are weighing map changes that could threaten up to three more Democratic incumbents.
Virginia's current map will stay in place for 2026, removing a path for as many as four additional Democratic seats; Florida has already enacted a Republican-backed redraw aimed at adding four GOP seats.
The redistricting fight is colliding with primary season, with Nebraska's 2nd District — a seat Democrats likely need for a House flip — voting Tuesday.

What are the unseen logistical costs for states that redraw voting maps just before an election?
Supreme Court’s 2026 Redistricting Ruling: How Louisiana v. Callais Reshapes Voting Rights, Minority Representation, and the Battle for the U.S. House
Overview
The Supreme Court’s 2026 decision in Louisiana v. Callais struck down a key voting map, ending a major legal dispute and setting off immediate changes in U.S. election rules. This ruling weakened a landmark civil rights law and allowed other states to redraw their congressional maps, making it harder to challenge racial discrimination in voting. Experts warn this will reduce diversity and representation in the House of Representatives, as new maps may dilute minority voting power. The decision has reshaped the political landscape for the 2026 midterms, with both parties racing to redraw districts and secure their advantage.
