Bonus Bet Converter
How It Works
Turn a free bet into cash you keep.
How This Works
A bonus bet stakes but never returns, so its cash value is what the other side pays. We hold every book's price and size the cover bet that turns yours into the most cash, at the prices shown.

Your Hedge Goal. Get My Stake Back: hedge just enough to get your stake back if your bet loses, and keep the rest if it wins. Also called a free roll. Equal Profit Either Way: hedge so you end with the same amount whichever side wins. Lock In A Set Profit: locks at least this many dollars whichever side wins, at the prices shown. Get Back a Set Amount: hedge so a set amount comes back if your bet loses. The rest rides on your bet. Lock In An ROI: locks at least this return on your stake whichever side wins, at the prices shown. Profit On One Side: make this profit if the hedge wins, and let the rest ride on your bet. Never Lose: the smallest hedge where neither result loses. Partial Hedge: hedge part of the equal hedge and keep more riding on your bet. Middle: both bets win when the result lands between two different lines. Spreads and totals only. Compare a Cash-Out Offer: type the cash-out offer your book shows and compare it with hedging.
Parlay Hedge. One Leg at a Time: hedge only the first-resolving leg now, then re-run here after each leg wins. Keeps the most, but the later hedge prices can move on you. Cover All Legs Now: place every hedge today for a floor you know now. Removes line-movement risk, costs more vig; the floor can be negative unless the parlay is deep in the money.
What a Hedge Finder Does
A hedge finder locates the best available price on the opposite side of a bet you already placed, so you can lock in a profit or cap a loss before the result lands. A hedging calculator tells you how much to stake once you have found both prices yourself. A hedge finder goes further: it already holds every book's number, so it finds the price and does the math in one pass.
How This Hedge Finder Works
The Odds Gap holds live prices from every tracked book, sportsbooks and prediction-market exchanges alike, including Kalshi, Polymarket US, ProphetX, and Novig. Pick your game and side, enter your stake, and the scanner ranks every hedge from best to worst with the exact stake to place and the profit you lock either way. It runs seven modes: a standard hedge on any open bet, free bet conversion, profit and odds boosts, no-sweat bets, wager requirements, a futures hedge that backs the rest of a tournament field at each outcome's best price, and a full arbitrage scan across the whole board. Every result links straight to the book carrying the price, and nothing here requires a signup.
When to Hedge
Hedge when a number locked in at the prices shown is worth more to you than the gamble: the last leg of a long parlay, a futures ticket that has shortened hard, or any spot where the swing is bigger than you want to carry. If a book has offered you a cash-out, enter it and the tool tells you whether that offer beats the real market or shorts you.
Two tools of their own: the Cash Out Calculator compares a cash-out offer with what the bet is worth at fair prices and with a hedge, and the Bonus Bet Converter turns a bonus bet into cash at the best prices.
The Honest Math
Hedging locks a result, but it costs expected value. The hedge leg pays the second book's vig, so your average outcome is slightly worse than letting the bet ride. That is the whole trade: certainty now for a small haircut on EV. We show you the locked number and the breakdown either way, and you decide. Math, not picks. Lines move fast, so re-check the price before you place.
The Odds Gap Daily
One email each morning: how the lines moved in last night's big game, new finds from Trends, and where the books disagree most on the weekend slate.
