kalshi
If ALL of the following occur: Democrats hold 235 or more seats in the House after the 2026 midterms AND Democrats hold 51 or more seats in the Senate after the 2026 midterms, then the market resolves to Yes.
This is a combination market requiring ALL specified outcomes to occur for the contract to pay out. If ANY single component resolves to No or becomes impossible, the entire contract immediately resolves to No. Each component is resolved according to its corresponding Kalshi ruleset: "Will Democrats hold 235 or more seats in the House?" uses SEATSCONGRESS, "Will Democrats hold 51 or more seats in the Senate?" uses SEATSCONGRESS. For economic data releases, resolution uses the first officially released value (not preliminary or revised estimates unless specified). All conditions must be satisfied within the specified time period.
This market will resolve based on the composition of the U.S. House of Representatives and the Senate on February 1, 2027. Individuals caucusing with either party will be included with them (e.g. an Independent who caucuses with a party, like Vermont Senator Bernie Sanders who caucuses with the Democrats, would be counted as a Democrat).

recent wire items
- Blue tsunami in 2026 wavers below majority pricing at midterms Kalshi 36%
- Kalshi prices a blue tsunami in 2026 at 36%, a meaningful probability but still below majority odds.
- News of Democrats threatening double-digit Trump districts suggests structural risk for Republicans; the market is partially pricing this but not calling it the base case.
- Polymarket on House control (CM-EVT-2N6T7M0T15) prices Republicans retaining the House at 83%, showing the market sees Democratic gains as possible but not wave-level.
- Resolves via Bureau of Labor Statistics; resolution mechanics are non-standard for an election outcome and should be verified against contract terms.
