How betting odds work: what they are and how to use them

In most cases, the favorite will have negative moneyline odds (less payoff for a safer bet) and the underdog will have positive moneyline odds (more payoff for a risky bet). A «moneyline» wager refers to odds on the straight-up outcome of a game with no consideration to a point spread. For example, 6/5 fractional odds (also described as «1.2» or «6 to 5») are the same as 11/5 decimal odds (also described as 2.2 or «11 for 5).

Free bet – one-time stake of £30, min odds 1.5, stake not returned. To qualify, place a min £10 bet from your cash balance at odds of EVS or higher—only your first bet counts, and it must not be voided or cashed out. Free bet – one-time stake of £10, min odds 1.5, stake not returned. Min 10 qualifying bets, stake not returned.

However, in more variable situations, such as a multi-runner horse race or a football match between two unequally matched teams, betting «at odds» provides the possibility to take the respective likelihoods of the possible outcomes into account. Similarly, fair betting odds can be expressed as «(1−p)/p to 1», «1/p for 1», «+100(1−p)/p», «−100p/(1−p)», «D−N to N», «D for N», «+100(D−N)/N», or «−100N/(D−N)». In gambling, odds are often given as the ratio of the possible net profit to the possible net loss, and sometimes this is called fractional odds. Our basketball odds page brings together the games of the day, while results and standings go back several seasons. On the blocked odds page, you will be able to see matches or markets that online bookmakers are no longer offering odds for, which can signal a change in the market before other operators react to it. It is where the hot odds of the day show up first, and you can filter it by the last hour, 12 hours or 24 hours, by the percentage of bookies cutting their price and by market.

Instead of betting on a single game, you’re predicting outcomes like who will win the NBA championship, MVP award, or a division title. Bettors predict whether the total points scored will be above or below a set number. For example, if a team is -5.5, they need to win by 6 or more points to win the bet.

Betting odds are usually expressed either as fractions (e.g. ‘3/1’) or as decimals (e.g. 4.0). All of these have different possibilities, probabilities, chances – or odds – of happening. They give you a quick indication of how much you could expect to win if your bet wins.

They’re especially popular in horse racing, where bettors often look for value in underdog picks or assess returns more precisely using this format. Fractional odds can be a bit trickier to calculate quickly, but they’re favored by many bettors for how clearly they represent the risk-reward ratio. If you bet $10 at 7/2, you’d get $35 in profit plus your initial $10 back, totaling $45. They’re expressed as fractions, like 5/1 or 7/2, showing the ratio of profit to the original stake. Decimal odds make comparing bets straightforward because you’re seeing the total return value in one number. Higher numbers indicate higher potential payouts, while lower numbers signify favorites and lower returns relative to the stake.

In probability theory and statistics, odds and similar ratios may be more natural or more convenient than probabilities. Odds can also be expressed as a number, by dividing the terms in the ratio—in this case it is unique (different fractions can represent the same rational number). For example, «odds of a weekend are 2 to 5», while «chances of a weekend are 2 in 7». Implied by this definition is the fact that the probability of an event is given by the ratio of favourable outcomes to the total number of possible outcomes. If k is any positive number then X to Y is the same as kX to kY, and similarly if «to» is replaced with «in» or «for». Multiplying these probabilities by 100% gives the percentage.

A «wholesale odds» index is an index of all the prices in a probabilistic market operating at 100% competitiveness and displayed without any profit margin factored for market participants. However, if the teams are evenly matched, both teams can have a negative line at the same time (e.g. −110 −110 or −105 −115), due to house take. The use of odds in gambling facilitates betting on events where the probabilities of different outcomes vary.
