Point spread

Year Total sports betting revenue in the US (in billion USD)
2019 12.03
2020 21.5
2021 28.4 (projected)

A point spread is a type of sports betting where a bookmaker handicaps a particular game by subtracting points from the favored team’s score or by adding points to the underdog’s score. The purpose of this is to create a more even betting field and encourage betting on both sides of the game. The spread can be either a positive or negative number, which determines which team is the favored or underdog team. For example, if a spread on a football game is listed as -7, that means that the favored team must win by more than 7 points in order for a bet to be successful. With the growth of sports betting, total revenue in the US increased from $12.03 billion in 2019 to a projected $28.4 billion in 2021.

Vigorish (or “vig”) is the commission charged by bookmakers for accepting bets from gamblers. It usually ranges from 5%-10% and is a way for bookmakers to make money regardless of the outcome of the sports event. For instance, if the total amount of bets placed on both teams in a basketball game is $11,000, and the bookmaker’s vig is 10%, they would make $1,100 regardless of which team wins. Therefore, it’s essential to factor in the vig when evaluating sports betting numbers as it can significantly reduce the potential payout.
