Sports odds on Polymarket and Kalshi

Sports drive more than 80% of all prediction market volume, and both venues carry the same championship and award markets — Super Bowl, NBA title, Champions League, college football, MVP races. Because these run for a whole season, the same contract stays live for months and the two books have plenty of time to drift apart.

Prediction market contracts price differently from a sportsbook line: you are buying a contract that settles at $1, not taking a fixed-odds price against the house. Prediction markets vs sports betting covers what changes, and the best platforms for sports ranks the venues on depth.

Frequently asked questions

Are prediction markets cheaper than a sportsbook?

Often. A sportsbook bakes a margin into the line, usually four to five percent on a two-way market. Prediction markets charge an explicit fee instead, so the all-in cost is typically lower — though single-game liquidity is thinner. More in prediction markets vs sports betting.

Can I trade individual games, not just championships?

Both venues list individual games. This page tracks season-long championship and award markets, where a contract stays live for months and the comparison holds up over time.
