Seat-Level Fundamentals & Redistricting Model

For a House seat, the district's partisan lean, incumbency status and the national environment explain most of the outcome before any polling exists — and cheap, unpolled races are where markets are least efficient. When maps are redrawn, the old lean is obsolete and the market often keeps using it. You build a seat-level model from district composition and trade the many small races nobody bothers to price carefully.

What you need to run it

District partisan-lean data updated for the current maps, plus incumbency and candidate quality
National-environment estimate feeding a uniform-swing-plus-noise model
Coverage across many low-liquidity races, since the edge is spread thin per seat

Where this applies

Markets on Polymarket where seat-level fundamentals & redistricting model is the natural play:

Will Democrats win the 2026 Texas 15th district?
Will Republicans win 220 or more House seats in 2026?
Will the incumbent hold this competitive House seat?
