A dead heat occurs when two or more competitors finish in an exact tie for the same position. Rather than voiding your bet, bookmakers apply dead heat rules that reduce your payout proportionally.
How Dead Heat Calculation Works
The formula is straightforward: divide your stake by the number of tied competitors, then apply full odds to the reduced stake.
Example: You place a £10 bet on a horse at odds of 6.00. Two horses cross the line together in a dead heat for first place.
- Effective stake: £10 ÷ 2 = £5
- Payout: £5 × 6.00 = £30
- Without dead heat: £10 × 6.00 = £60
You receive £30 instead of £60 — half the potential return, not half the odds.
Where Dead Heats Commonly Occur
Horse Racing
Dead heats in horse racing are relatively rare but do occur. The photo-finish technology determines whether a dead heat is declared. This applies to both win and place positions, which is particularly relevant for each-way bettors.
Golf
Dead heats are far more common in golf betting, especially in top-5, top-10, and top-20 markets. If three players tie for 8th place and you have backed one of them in a top-10 market, dead heat rules apply because only two of those three tied players can fill the remaining top-10 spots.
Football Top Scorer
If you back a player at 10.00 to finish as the Premier League top scorer and two players end the season on 22 goals each, dead heat rules reduce your payout by half.
Each-Way Bets and Dead Heats
Each-way bets add complexity because the win and place portions are settled independently.
Scenario: Your horse dead-heats for 3rd place in a race offering 1/4 odds for the first four places.
- The win part of your bet loses (your horse did not win).
- The place part is subject to dead heat rules — your place stake is divided by the number of horses sharing 3rd place, then paid at the each-way fraction.
How to Manage Dead Heat Risk
- Check market terms — Some bookmakers settle top-goalscorer or top-batsman markets differently, using alternative tie-break rules instead of dead heat.
- Favour outright win markets — Dead heats are rarer in win-only markets compared to top-finish or place markets.
- Account for the edge — In golf, where dead heats are frequent, reduce your expected value calculations by 5-10% to account for the dead heat probability.
