Hedging means betting the other side of a wager you already hold so that you collect something either way. Divide your ticket's total return by the decimal odds of the other side to get the stake that pays the same on both outcomes. It is not free: two-way markets in our archive kept a median 4.16%, and the hedge leg pays that.

What is hedging in sports betting?
Hedging is placing a second bet on the opposite outcome of a bet you already hold, so that you collect something whichever way the event finishes. It is used on tickets whose price has moved a long way since you placed them, most often futures and parlays with one leg left. It reduces how much the result can swing your money in either direction.
How do you calculate a hedge bet?
Take the total return your open ticket would pay, then divide it by the decimal odds of the other side. That stake pays the same amount whichever outcome lands. A $100.00 ticket at +600 returns $700.00. If the other side is now −140, decimal 1.7143, the equal-payout stake is $408.33.
| Outcome | Ticket pays | Hedge pays | Total staked | Net |
|---|---|---|---|---|
| The ticket wins | $700.00 | $0.00 | $508.33 | +$191.67 |
| The hedge wins | $0.00 | $700.00 | $508.33 | +$191.67 |
A $100.00 bet at +600 hedged with $408.33 at −140. Both rows land on the same net by construction, which is what the equal-payout stake is for. Left alone, the same ticket pays +$600.00 if it wins and −$100.00 if it does not.
Two other stakes get used. Staking to break even, $140.00 here, returns your original outlay if the hedge lands and leaves more on the table if the ticket wins. A partial hedge is any stake below the equal-payout figure: it narrows the gap between the two outcomes without closing it. Our hedge calculator does all three.
How much does hedging cost?
A hedge is not free, because the second bet is placed into a market that is priced to keep a margin. Across 711,756 two-way head-to-head quotes in our archive the two implied probabilities summed to a median 104.34 rather than 100, so the median hold was 4.16%. The middle half of quotes ran 104.01 to 104.93.
That margin is the floor, not the whole cost. What the hedge actually costs you depends on how far the price moved between the two bets. If the original price was a fair reflection of the outcome, hedging lowers the spread of results and lowers the average one at the same time, by roughly what the second market keeps. Hedging buys certainty and the margin is the price of it.

Two-way head-to-head markets only, 2025-01-01 to 2026-08-06. Soccer sits outside this table because its head-to-head market prices three outcomes, not two: 2,711,285 of the quotes in the window were three-way and are excluded from every figure on this page.
Where you hedge changes what it costs
The margin is not the same everywhere. Across the same window the median two-way hold ran from 2.10% to 4.29% depending on the book. On a hedge stake the size of the one above, $408.33, that difference is real money.

Lowest median hold first, among books with at least 500 two-way quotes in the window. A betting exchange charges commission on winnings separately, so its posted prices are not directly comparable with a sportsbook's.
When does the math favour hedging?
The arithmetic favours it when the stake is large relative to what you can comfortably lose, when the price has moved far enough that the locked amount is close to what letting it ride would average, and when the second market is cheap. It favours letting the ticket stand when the hedge price is poor or the position is small enough that the swing does not matter to you. This is a question about your own tolerance for variance, and it is yours to answer.
How do you hedge a parlay?
The same way, once one leg is left. Treat the remaining return as the ticket value and price the hedge against the final leg alone. A parlay with two legs outstanding cannot be fully hedged with a single bet, because no single market covers both results at once. You would need to cover every surviving combination, which multiplies the margin you pay.
How do you hedge a free bet or bonus bet?
A free bet usually returns winnings only, not the stake, so the return it is hedged against is the profit alone. That changes the stake and it changes the result: hedging a stake-not-returned bonus converts part of its face value into cash you keep whichever way the game goes. How much depends entirely on the two prices, which is what the calculator is for.
Hedging, arbitrage and middling are not the same thing
A hedge is a second bet on a ticket you already hold, taken at whatever the price now is, and it may leave you ahead or behind. Arbitrage is two bets placed together across books whose prices disagree enough to cover every outcome. A middle is two bets on different numbers that can both win if the result lands between them, and that both cannot lose only if the numbers overlap. The arbitrage guide covers the second and third.
How this was measured
- Source. odds.lines, market_key h2h, 2025-01-01 to 2026-08-06: 711,756 two-way quotes across 37 bookmakers, 23,171 events and 27 sports.
- One quote. One bookmaker's prices for one event at one capture instant. A quote is included only if the book priced exactly two outcomes; three-way markets are counted separately and excluded, never averaged in.
- Overround and hold. Each American price is converted to an implied probability and the two are summed. A market with no margin sums to 100. Hold is the excess divided by the total, which is the share of a two-sided market the price structure keeps.
- Exclusions. 598 rows of 9,558,002 in the window (0.006%) carried a price outside the range a real American line can take and were dropped rather than repaired.
- Percentiles. percentile_disc, so every figure quoted is a value that was actually observed rather than an interpolation between two of them.
- What this data cannot tell you. These are pre-game listed prices from a capture archive. They are not closing lines and nothing here measures in-play prices, which is where many hedges are actually placed.

Frequently asked questions
Is hedging a bet risk-free?
No. A hedge removes the swing between the two outcomes but it cannot remove cost. The second bet goes into a market priced to keep a margin, a median 4.16% across 711,756 two-way quotes in our archive, and either leg can still be voided or graded in a way you did not expect. Certainty about the result is not the same as a guaranteed profit.
Does hedging guarantee a profit?
Not by itself. Whether a hedge leaves you ahead depends entirely on how far the price moved after you placed the original bet. If it moved in your favour the hedge can lock a gain; if it did not, hedging locks a loss instead. The arithmetic makes the two outcomes equal, not positive.
How do I calculate the hedge stake?
Divide the total return of your open ticket by the decimal odds of the other side. A $100.00 ticket at +600 returns $700.00, so against a −140 other side, decimal 1.7143, the equal-payout stake is $408.33 and you finish on $191.67 either way.
Should I hedge my bet?
That is a question about your own tolerance for variance and we do not answer it for you. What the arithmetic says is narrow: hedging trades a wider range of outcomes for a narrower one, and charges you the second market's margin to do it. This site publishes no picks and no recommended wagers.
Is hedging the same as arbitrage?
No. Arbitrage is two bets placed at the same time across books whose prices disagree. A hedge is a second bet on a position you already hold, at whatever price exists now, and it can leave you behind where an arb by definition does not.
