A "dead heat" occurs when two or more competitors or teams finish an event with identical results, making it impossible to determine a clear winner. This can happen in horse racing, athletics, swimming, and certain team sports where a tie is possible.
Dead heat rules apply when a bet's outcome ends in a tie between two or more participants. These rules vary depending on the bet type and sport involved — for the specific rules that apply to your bet, see the Betting Rules section.
