How these odds work

Prediction markets let traders buy and sell contracts on election outcomes, so prices reflect real money at stake rather than pundit ratings. For every race we track the markets on both Kalshi and Polymarket and blend their prices weighted by volume, so the deeper market counts for more. Odds are probabilities, not guarantees: a race priced at 50 percent is a coin flip.
