Precinct-Reporting Nowcast

On election night the raw vote total is deeply misleading, because precincts report in a non-random order — urban centers and mail batches often come late, producing a lead that predictably evaporates. A model that knows each precinct's historical partisan lean and expected turnout can convert partial returns into a projected final margin while the market is still reacting to the running total. This is the single largest recurring mispricing in political markets.

What you need to run it

Precinct- and county-level historical results with expected-vote-share modeling
Live returns feed at county granularity, not just statewide totals
Uncertainty bands that widen appropriately when reporting patterns break from history

Where this applies

Markets on Polymarket where precinct-reporting nowcast is the natural play:

Will Democrats win the 2026 Pennsylvania Senate race?
Will Republicans hold the Georgia governorship in 2026?
Will the Democratic candidate win the Arizona Senate seat?
