Traders currently price "Texas" at 98% for "Which states will use new congressional maps in the midterms?". Full distribution: Texas 98%, Florida 98%, California 98%, North Carolina 96%. The market has traded $395K in total volume and resolves Nov 3, 2026. Ten states—Alabama, California, Florida, Louisiana, Missouri, North Carolina, Ohio, Tennessee, Texas, and Utah—have enacted new congressional maps for the 2026 midterms through mid-decade redistricting, a process accelerated by the Supreme Court’s May 2026 Louisiana v. Callais ruling that adjusted standards for racial considerations under the Voting Rights Act. Partisan legislative majorities drove most changes, with additional influence from ballot measures in California and ongoing federal litigation that has largely upheld the new lines. Primary elections and candidate filing deadlines have already shifted in several states to accommodate the maps, while attempts in other states were rejected or stalled by courts. Remaining legal challenges and any late adjustments before November could still affect which boundaries are used.
