Dead Heat Rules in Betting: How Bookies Pay a Dead Heat

Dead heat rules decide what happens to your bet when two or more horses cross the line together and the Judge can’t separate them. The short answer: your stake is divided by the number of horses that tied, the divided stake is paid at your full odds, and the rest of the stake is lost. So £10 on a 4/1 winner that dead-heats with one other horse is settled as £5 at 4/1, a £25 return instead of £50.
That one rule covers most bets, but it plays out differently in each way bets, doubles and accas, forecasts, Tote pools and other sports. This guide takes each case in turn with worked examples, and shows how to check the numbers in our bet calculator.
What Is a Dead Heat in Horse Racing?
A dead heat is a tie for a finishing position. In racing it usually means a tie for first, but horses can dead-heat for second, third or any other place, and it is the places that matter most to each way backers.
How the Judge Calls a Dead Heat
In Britain the result is called by the British Horseracing Authority’s judges, using the photo finish. In March 2026 the BHA announced that Lynx photo finish cameras capturing images “at around 6,000 frames per second” were in use on British racecourses, giving its judging team clearer pictures in tight finishes. The BHA’s Judge and team principal, David Hicks, said that “the judging process itself doesn’t change”, and added that “it won’t always be possible to split horses, with dead heats an inevitability at times”.
For betting, the result that counts is the one at the weighed-in announcement. Tattersalls Rule 8 says any bet on a photo finish “will be settled according to the result at the time of the ‘Weighed-In’ announcement”, and our guide to the stewards’ enquiry explains what can change before that point.
Why Is It Called a Dead Heat?
Wikipedia’s article on the term says the Oxford English Dictionary traces it to horse racing. Meetings used to run the same horses in several heats, and the winner was decided on the number of heats won. A heat with no clear single winner was discounted from the tally and was therefore “dead”.
Famous Dead Heats
Wikipedia’s list of dead heat horse races includes the 1884 Epsom Derby, between Harvester and St. Gatien, and the 2018 Ayr Gold Cup, between Baron Bolt and Son of Rest. The same article notes that both recorded quadruple dead heats in racing were in England in the 1850s. According to Wikipedia, the photo finish, first used in racing in the second quarter of the 20th century, notably reduced the number of dead heats.
Dead Heat Rules: How Bookies Pay a Dead Heat
The rule is the same in every UK bookmaker’s rules we read for this guide, because it comes from the industry’s settlement rules rather than any one firm’s terms.
The Stake Is Divided, the Odds Stay the Same
The Tattersalls Committee Rules on Betting put it in Rule 10: “a bet on either horse involved in the dead heat loses half the stake, with full odds being applied to the remaining half (if there is a triple dead heat or more, the reduction is in proportion)”. Sky Bet’s dead heat help page describes the same calculation: divide the total stake by the number of participants in the dead heat, then multiply by the odds. It adds that “one part of your bet is treated as a winner, and one part as a loser”.
So a dead heat changes your stake, never your price. The formula is:
Return = (stake ÷ number of horses tied) x decimal odds
Worked Example: £10 at 4/1 in a Two-Way Dead Heat
You back a horse for £10 at 4/1 (decimal 5.0) and it dead-heats for first with one other.
- Divided stake: £10 ÷ 2 = £5.
- Winning half: £5 x 4 = £20 winnings, plus the £5 stake, so a £25 return.
- Losing half: the other £5 is lost.
- Result: £25 back on a £10 bet, a profit of £15. Had the horse won outright, the return would have been £50.
The Equivalent Odds Shortcut
Another way to see it: a dead heat is the same as a bet for your full stake at lower odds. Divide the decimal odds by the number of horses tied. At 4/1 the decimal is 5.0, so a two-way dead heat is worth 5.0 ÷ 2 = 2.5, which is 6/4 in fractional odds. £10 x 2.5 = £25, the same answer as the stake split. A 10/1 shot (decimal 11.0) in a two-way dead heat works out at 5.5, or 9/2.
Dead Heat Payouts at a Glance
Here is what a £10 win bet returns at different prices, depending on how many horses share first place. Returns include the stake, rounded to the nearest penny.
| Odds | Sole winner | Two-way dead heat | Three-way dead heat |
|---|---|---|---|
| 10/11 | £19.09 | £9.55 | £6.36 |
| 2/1 | £30 | £15 | £10 |
| 4/1 | £50 | £25 | £16.67 |
| 10/1 | £110 | £55 | £36.67 |
| 20/1 | £210 | £105 | £70 |
The working for the 10/1 line: £10 ÷ 2 = £5, and £5 x 11 = £55, which matches Sky Bet’s own example. In a three-way tie, £10 ÷ 3 = £3.33 (rounded), and £3.33 x 11 is about £36.67.
When a Winning Bet Still Loses Money
Look at the 10/11 row. A dead heat on an odds-on horse returns less than you staked: £9.55 back from £10. Betfair’s help page makes the same point with a £50 back bet at 1.60 that dead-heats for first, an overall loss of £10 “although your selection wins the race”. In a two-way dead heat you only break even at evens (decimal 2.0). In a three-way dead heat the break-even point is 2/1, which is why the 2/1 row returns exactly £10.
Triple Dead Heats and Beyond
The rule simply scales. Three horses tied means a third of the stake at full odds; four means a quarter. Our calculator handles up to four horses tied, which covers anything you are likely to see in racing.
Dead Heats in Each Way Bets
An each way bet is two bets, one to win and one to place, and the dead heat rule is applied to each half separately. For the basics and place terms, see our guide to what an each way bet is. The question for the place half is how many paying places the tied horses share.
How Many Places the Tied Horses Share
Sky Bet’s help page gives the formula in its golf example: the stake is divided by “number of places remaining” over “the number of participants involved in the dead heat”. Paddy Power’s page uses the same wording, and Betfair says its calculator applies dead heat settlement to “all types of events”. If the tied horses fit inside the remaining places, the place half is paid in full. If there are more tied horses than places left, the stake is cut in proportion.
A Dead Heat for First
£5 each way (£10 total) at 6/1 in a non-handicap with eight runners, paying 1/5 the odds for three places. Your horse dead-heats for first with one other.
- Win half: £5 ÷ 2 = £2.50 at 6/1. £2.50 x 7 = £17.50 returned.
- Place half: two horses share first and second, both inside the three places, so the full £5 is paid at 6/1 x 1/5 = 6/5. £5 x 2.2 = £11 returned.
- Total: £28.50 back on £10. Without the dead heat, the win half would have returned £35, for £46 in all.
A Dead Heat for the Last Paying Place
£10 each way (£20 total) at 16/1 in a 16-runner handicap paying 1/4 the odds for four places. Your horse dead-heats for third with two others. The three tied horses share third, fourth and fifth, but only two of those places (third and fourth) pay.
- Win half: loses.
- Place half: two places remaining ÷ three horses tied = two thirds of the stake. Two thirds of £10 is £6.67, settled at 16/1 x 1/4 = 4/1, so £6.67 x 5 = £33.33 returned. The other £3.33 is lost.
- Total: £33.33 back on £20, against £50 if your horse had finished third alone.
A two-way dead heat for third in a race paying three places is simpler: one place, two horses, half the place stake. Big fields with extra places, such as the Grand National, are where a tie on the last paying place matters most.
When a Dead Heat for a Place Makes No Difference, and a Caveat
On the formula above, a two-way dead heat for second in a race paying three places costs you nothing on the place half: two places remain, two horses share them. Be aware that not every help page agrees. bet365’s dead heat page works through a horse tying for second in a race with 1/5 odds, places 1-2-3, and halves the place stake. If a bookmaker settles a placed dead heat in a way you don’t expect, check its rules for that market and ask for the working.
In our each way calculator, a horse marked Placed with a dead heat gets one more option, Paid places the tie covers. Leave it at 1 for a tie on the last paying place; pick 2 for the examples above where two paying places are shared (a two-way tie for second of three places, or the three-way tie for third of four), and the place half is settled on that share.
Dead Heats in Doubles, Trebles and Accumulators
In a multiple, the dead heat is applied to that one leg, and whatever the leg returns rolls on to the next.
How the Reduced Return Rolls On
Tattersalls Rule 10(a) says that in a double where one selection dead-heats, “the stake on this selection is halved and full odds applied. This then becomes the stake on the other selection.” If the other selection dead-heats too, “the stake is again halved”.
Example: a £10 double. Horse A wins at 3/1 but dead-heats with one other. Horse B wins at 5/2.
- Leg A: £10 ÷ 2 = £5 at 3/1, so £5 x 4 = £20.
- Leg B: the £20 goes on at 5/2, so £20 x 3.5 = £70.
- Total return: £70, a profit of £60. Without the dead heat the double would have returned £10 x 4 x 3.5 = £140.
Check It in Our Bet Calculator
Every selection in our bet calculator has a Rule 4 / dead heat option. To reproduce the example: choose a double, enter a £10 stake, enter 3/1 and mark it Won, open Rule 4 / dead heat and choose “2 horses tied”, then enter 5/2 and mark it Won. The return shows £70. The same option sits on every row in the each way calculator and the acca calculator.
When Both Legs Dead Heat
If Horse B had dead-heated as well, the £20 from leg A is halved again: £10 at 5/2 returns £35. In an accumulator, every dead-heating leg halves (or thirds) the running total once, so an acca with two legs in two-way dead heats pays a quarter of its normal return.
Dead Heats and Rule 4 Together
A late withdrawal and a dead heat can hit the same race. Both reduce your return, and the order matters.
Which Comes First
Tattersalls Rule 10(b) settles it: “In the event of any withdrawals, Tattersalls Rule 4(C) reductions will apply to the winnings from the reduced stake.” So you halve the stake first, work out the winnings on that half, and then take the Rule 4 deduction from those winnings. The size of the deduction depends on the withdrawn horse’s price, which our Rule 4 calculator looks up for you.
Worked Example
£10 win at 6/1. A late withdrawal brings a 15p in the £ deduction, and your horse dead-heats for first with one other.
- Reduced stake: £5.
- Winnings on the reduced stake: £5 x 6 = £30.
- Rule 4 at 15p in the £: £30 x 0.15 = £4.50 off, leaving £25.50.
- Return: £25.50 plus the £5 stake = £30.50.
In our bet calculator, set the Rule 4 deduction to 15p and the dead heat to “2 horses tied” on the same row and you’ll get the same £30.50.
Forecasts, Tricasts and Tote Bets
Pool bets and dividend bets don’t use a single price, so dead heats are handled in the dividend rather than by cutting your stake.
Bookmaker Forecasts and Tricasts
Coral’s shop betting rules, for example, settle tricasts on “the appropriate industry Tricast Dividend”, and their forecast rules work from the declared straight forecast dividend, so the effect of a dead heat comes through in the dividend that is declared. Where you took a fixed Showcast forecast price, the same rules say “half the stake will be applied to the forecast at full odds and the other half will be lost”. Once the dividend is declared, our forecast calculator turns it into a return for straight, reverse and combination forecasts and tricasts.
Tote Win and Place Pools
The Tote’s betting rules (effective from 24 January 2024) split the win pool when horses dead-heat for first: “the net pool will be divided into as many equal parts as there are dead-heating runners”, and each part is divided by the stakes on that horse to give its dividend. The minimum dividend on a win bet involving dead-heating horses is 60p. In the place pool, when horses dead-heat for the final place, “the amount of the pool allocated to that place is divided equally between the dead-heating horses”.
Placepot and Jackpot
The multi-leg pools are kinder. In the Placepot, the rules say horses that dead-heat for any paying position are all considered fully placed, so no share of your line is lost. In the Tote Jackpot, “dead heats for first place count as equal winners”, so either horse carries your ticket through the leg.
Dead Heats on the Exchange and in Other Sports
Dead heats are rare in racing but common in sports where competitors finish level on a score.
Betfair Exchange: Back and Lay
Betfair’s dead heat page says the calculations are “exactly the same for backers and for layers”, with one rule to remember: “whatever the backer wins, the layer loses and whatever the backer loses, the layer wins”. Its example: a £20 lay at 5.0 on a horse that dead-heats for first. The backer’s £10 winning half makes £40 profit, the losing £10 half goes to the layer, so the layer loses £30 rather than the full £80 liability.
Golf Each Way and Top Finishes
Golf produces ties for places all the time. Sky Bet’s example is an each way bet at 1/4 the odds for three places, where three players tie for third: one place remaining, three players tied, so the place stake is cut to a third. With four places paid, two places remain and the stake is cut to two thirds. bet365 adds that in markets which include a tie, such as 2 Balls with the tie priced, dead heat rules don’t apply and a bet on a player who ties is a loser.
Football Top Goalscorer
Sky Bet’s help page uses a three-way tie for top scorer. A £10 bet at 6/4 becomes £3.33 at 6/4, a return of £8.33, less than the stake. A £20 bet at 20/1 becomes £6.67 at 20/1, a return of £140.
When Dead Heat Rules Don’t Apply
Sky Bet’s rules are clear: “Dead heat rules do not apply when the tie or draw is offered in the market.” If you could have backed the tie, a tie is a separate result, not a shared win.
Betting always carries a risk of loss and no tipster, system or staking plan can guarantee a profit. Only stake what you can afford to lose, and set a budget before you start. Gambling responsibly.
Frequently asked questions
They split your stake by the number of tied horses and pay that share at the odds you took. With two horses level, half your stake wins at full odds and the other half is lost. Three tied means a third wins. The price itself is never cut, only the stake.
It is settled as partly won and partly lost. You get back a fraction of your stake plus winnings at your price, so the return is smaller than an outright win. On short prices the return can be below your stake, for example any odds-on horse in a two-way tie.
The horses that can't be split are all given the same finishing position, so a dead heat for first gives the race two winners and each is credited with the win. Betting is settled on the official result at the weighed-in signal, with dead heat rules applied to every bet on the tied horses.
The term comes from racing in the days when horses ran several heats at one meeting and the overall winner was decided by heats won. When a heat had no single winner, it was left out of the count. That discounted heat was described as dead, and the name stuck.
Golf ties are settled on the places left in the market. Bookmakers divide the places remaining by the number of players tied and apply that fraction to the stake. Five players sharing the last two paid places would have two fifths of the stake settled as a winner at the agreed odds, and the rest lost.
