How Polymarket Election Markets Work (Winner, Party Control and Margins)

Explainer · live examples updated November 9, 2026, twice a day

Election markets ask who wins a race, which party controls a chamber, or by how much a candidate wins. Winner markets list each candidate as its own yes/no outcome; party-control markets usually have two or three outcomes.

Prices react to polls, debates and early returns, which makes them a live read of how traders see the race — a different signal from polling averages.
