Hedge Checker: Do Both Bets Settle the Same Way?
A hedge only protects you if both bets settle the same way when something unusual happens. Pick a market and the two places you plan to bet. The Hedge Checker shows how each one settles a scratch, a substitute, a retirement or a postponement, and whether your hedge still holds.
Read these guides first: Sportsbook House Rules and Kalshi and Polymarket Market Rules.
Key Takeaways
- A hedge only works if both legs settle the same way when a player doesn’t play, retires or the game moves.
- Most sportsbooks void a prop when the player doesn’t play. Kalshi and Polymarket US pay a fair price set by the exchange.
- Tennis retirements split sportsbooks. Some void the bet unless a set is finished, others pay the player who advances.
- A red result means one leg can lose while the other is refunded. Pick a different pair.
- Rules change and can vary by state. Read the rules on both markets before you bet.
Check Your Hedge
Pick the market, then the two platforms you plan to use. Each row shows how both platforms settle one case and whether they match.
Double-check before you bet. This checker covers the most common cases, not every rule. Rules change, can differ by market, state and location, and some cases below aren't covered by a platform's rules at all. Read the rules on both markets before you place either bet.
How to Read the Result
- Rules line up: both platforms settle every case the same way.
- Hedge with caution: both legs settle, but they can pay different amounts. A fair price on one side and a refund on the other is the usual case.
- Not safe to hedge: in at least one case, one leg is graded on the result while the other is refunded or paid a set price. You are left holding a live bet.
- Can’t confirm: one platform’s rules don’t cover a case. Check its rules before you bet.
