Prediction markets
Sports prediction markets
Championship futures and season-long props.
Sports prediction markets focus on the big season-long questions — who wins the Super Bowl, the NBA Finals, or the World Cup — rather than the night-to-night game lines that sportsbooks specialise in. Each price is a clean implied probability for a contender.
When a championship future trades on both a prediction market and a sportsbook, you can convert each to implied probability and back whichever offers the better number. That cross-venue comparison is the whole point.

Sports markets FAQ
- What are sports prediction markets?
- Sports prediction markets let traders buy and sell contracts on real-world outcomes — championship futures and season-long props. The contract price reflects the crowd's implied probability of each outcome.
- Where can I trade sports markets?
- Polymarket and Kalshi carry the deepest liquidity for most questions, with Manifold offering a play-money signal. OddsGrab lines up each platform price for the same event so you can take the cheapest side.
- How is the "best" price decided?
- For a buyer, the best price is the lowest one — it costs less to back the same outcome, so the payout is larger. We highlight the cheapest tradeable price per selection across platforms.
