Sports Betting – What is Expected Value (EV) Betting?


Betting is a form of gambling that involves placing wagers on the outcome of a sporting event. This can be done either on an individual game or in conjunction with a series of bets on multiple games.

There are a variety of types of bets, but the most popular are those based on the point spread or money line. These include straight bets, futures bets, and parlays.

Expected Value

Expected value, or EV for short, is one of the most common tools used by sports bettors and has roots in probability theory. It measures the expected value of a variable, such as a team’s chances of winning a game, by multiplying the probability that it occurs with the sum of all possible values and dividing it by the number of times it is likely to occur.

The odds for a team are determined by its perceived strength and can vary dramatically from bookmaker to bookmaker. It is a good idea to shop around at a few different books before making your bets, so that you can get the best value.

+EV betting is the practice of betting on teams that are projected to win a game with a higher expected value than the line offered by a sportsbook. This is a valuable strategy that can help you make more money in the long run by increasing your profit potential without having to risk more of your own money than you would otherwise have to.

It is important to remember that EV betting is not for everyone, but it can be an effective tool for many people. It is also a great way to boost your bankroll, as it can allow you to place smaller bets without having to worry about losing a large amount of money.

A +EV bettor will look at every team that is available for betting and decide whether there is value in it. This can be difficult, but it is an important step in a successful betting strategy.

Favorites immediately attract a lot of bettors, but they don’t offer the same type of value as underdogs. This is because the favorite’s price is inflated by popular franchises and fans.

This means that a bettor who backs the favorite will receive a higher payout, but they will also lose a greater percentage of their bets than those who bet on an underdog. This can be a problem for those who want to earn a high return on their bets, but it’s worth it if you have a solid reason to believe that the underdog will win.

Line shopping

Buying a bet is an important strategy in sports betting, and it’s especially useful for those looking to place over/under bets. When placing an over/under bet, you need to check the lines at a number of online sportsbooks before committing to your final choice.

While most bettors don’t have the knowledge or experience to find the weak points in a book’s line, it is a skill that can be learned and developed over time. By checking a few different sportsbooks’ lines before you place your bets, you can get the best value for your money and increase your profits while still maintaining an acceptable level of risk.
