Exchange: What happens if there is a dead heat? Dead Heat is a tie between two or, rarely, more runners in a race. Usually, a photo finish can determine the winner, but at times it is too close to call. If there is a Dead Heat, you will win part of your bet and lose part of your bet. A Dead Heat is most common in horse racing and greyhound markets but occur in other sports such as Golf as well. A Dead Heat is calculated by dividing the stake proportionally between the number of winners in the event.
