recent wire items
  • 2026-08-30T00:00:00.000Z momentum-repricing
    Democrats taking back the House stays heavily favored Kalshi 84%
    • Kalshi puts 84% probability on Democrats winning the U.S. House in the next election, a strongly favored outcome.
    • The White House staff exodus, including Leavitt's departure, is consistent with the market's heavily Democratic lean but does not by itself move the needle on pricing.
    • A companion Kalshi contract (CM-EVT-T5VXKJT451) puts only 47% on Republicans holding at least one chamber, implying the Senate is the GOP's main remaining path to relevance.
    • Kalshi resolves via Library of Congress records; the contract settles on official chamber control, so partial gains without a majority flip would resolve NO.
  • 2026-08-26T00:00:00.000Z momentum-repricing
    Democrats favored to retake the House, odds stay high Kalshi 84%
    • Kalshi puts 84% odds on Democrats winning the U.S. House in the 2026 midterms, resolves via Library of Congress.
    • Intra-party Republican anger over new tariffs, combined with voters ranking affordability as the top concern, is consistent with the strong Democratic pricing.
    • Separately, the Kalshi 'blue tsunami' contract (CM-EVT-6CY3Y4C610) sits at only 39%, suggesting markets see a Democratic House win as likely but not a sweep scenario.
    • Resolves via Library of Congress certification of House majority composition after November 2026 elections.
  • 2026-08-24T00:00:00.000Z momentum-repricing

    • The Kushner-Jeffries meeting underscores Republican concern about House control, consistent with the market's heavily Democratic lean.
    • A companion Kalshi contract (CM-EVT-T5VXKJT451) puts Republicans controlling at least one chamber at 47%, implying the Senate is the GOP's more viable path.
    • Resolves via Library of Congress official chamber composition record after the 2026 election.
  • 2026-08-14T00:00:00.000Z momentum-repricing

    • Election-security concerns and state-level Democratic mobilization are consistent with a market strongly favoring a Democratic House flip.
    • Companion Kalshi contract on Republicans holding at least one chamber of Congress after the 2026 midterms sits at 47%, suggesting Senate control is far less certain.
    • Polymarket contract on a blue wave in 2026 is at 76%, broadly consistent with the Kalshi House reading and pointing to a Democratic sweep scenario as the market consensus.
  • 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.
