In horse racing the odds are determined by the bets placed. Betting stops when the race starts. These determine the final odds.
In the US, we use the parimutuel system which means that the betters set the odds by the money they bet. The more bet on a horse, the lower the odds. The favorite has the most money bet on him while a longshot is a horse with very little money bet on him.

Traditionally odds is a measure of the likelihood OS something occurring. However in horse racing it measures what your payoff will be if your bet wins. Fractional odds are what most of us are familiar with. If a horse is quoted at 4/1 then for every dollar you bet you win four dollars. Decimal odds indicate what your payoff will be if your bet wins, including your bet. For example if a horse is quoted at 5.00 then you will be paid five dollars for every dollar bet. In decimal odds, a price of 5.00 is the same as the fractional odds of 4/1. Moneyline odds indicate what your payoff will be in relation to a $100 bet. For example if the odds are 4/1 then the moneyline odds will be displayed as $400. If the odds are 1/4 then the moneyline odds will be displayed as negative $400. Fractional odds 4/1 = Decimal odds 5.00 = Moneyline odds $400 Fractional odds 1/4 = Decimal odds 1.25 = Moneyline ofdds -$400
