  • 2026-07-30T10:00:26.000Z momentum-repricing
    Democrats firmly favored to win the US House in midterms Kalshi 83%
    • The Kalshi prediction market prices an 83% chance Democrats win the US House in the next election.
    • An 8-point Democratic generic ballot lead from CNN is broadly consistent with the high Kalshi probability on a House flip.
    • The Kalshi contract on Republicans holding more governorships than Democrats after the midterms sits at 50%, suggesting a more mixed down-ballot picture.
    • The Library of Congress is the named resolution source; the contract settles on official certified election results.
  • 2026-07-26T00:00:00.000Z momentum-repricing
    Democrats winning the US House stays heavily favored at 84 percent Kalshi 84%
    • The Kalshi contract prices an 84% chance Democrats win the US House in the next election, resolving via Library of Congress.
    • Democratic polling leads and a focused affordability message from Jeffries are consistent with the strong odds, but the market prices in that structural advantages matter.
    • Companion Kalshi event CM-EVT-T5VXKJT451 puts only 43% on Republicans controlling at least one chamber after midterms, showing Democrats are favored in the House but the Senate remains contested.
    • Redistricting gains for Republicans cited in news are already in the market; the 84% hold suggests traders view them as insufficient to overcome the Democratic polling advantage.
  • 2026-06-14T00:00:00.000Z momentum-repricing
    Democrats retaking the House in 2026 solidifies near strong consensus Kalshi 79%
    • Kalshi prices a 79% probability Democrats win control of the US House in the 2026 midterms.
    • The NBC poll's five-point Democratic generic ballot lead is broadly consistent with the 79% pricing: markets and surveys align on a Democratic House lean.
    • The Polymarket House contract (CM-EVT-2N6T7M0T15) prices 83% for Democrats, a small cross-venue gap suggesting Polymarket is modestly more bullish on a Democratic flip.
    • Senate control (CM-EVT-M9WJY06T90) prices only 44% for Republicans, implying a potential split-chamber outcome is the market-implied base case heading into November.
  • 2026-06-08T11:29:39.000Z momentum-repricing
    Democrats favored to retake the House at 78 percent Kalshi 78%
    • Kalshi prices a 78% chance Democrats win control of the US House of Representatives after the 2026 midterms.
    • Republican urgency on a pre-recess legislative package reflects awareness of the hostile electoral environment the market is pricing.
    • The companion Kalshi contract on Republicans controlling at least one chamber sits at only 23%, a structurally consistent read.
    • Resolves via Library of Congress official certification of House composition following the November 2026 election.
