Kalshi 65%

record: CMSIG2026102502 | category: momentum-repricing | target: CM-EVT-T5VXKJT451 | published: 2026-10-25

4-bullet brief | narrative

Kalshi puts 65% odds on Republicans controlling at least one chamber of Congress after the 2026 midterms.
The story ties the Fed hold directly to midterm timing, but the Kalshi contract shows Republicans as clear but not overwhelming favorites.
A companion Kalshi contract puts 75% on Republicans holding more governorships than Democrats, suggesting broader GOP strength at the state level than in Congress.
Resolution depends on certified election results per Bureau of Labor Statistics designation as resolution source, with any contested races potentially delaying settlement.
