As sports betting becomes legalized in the United States, more and more professional leagues are forming partnerships with bookmakers that offer official betting lines for their games. These odds are calculated by taking into account the number of bets placed on each team or individual player, as well as the total amount wagered on all possible outcomes for a specific game. The more money that is bet on a specific outcome, the lower the odds will become.
A wager on a horse race involves placing a bet on the winner of a particular race or series of races. The goal is to correctly predict the first finishers in a race or series of races in order for the bet to win. A “quinella” entails picking the first two finishers in correct order; a “trifecta” is the same but with three winners; and a “superfecta” requires picking the first four finishers in exacta order.
The NHL and MLB have both partnered with sportsbook operators to provide official betting lines. The NHL has been able to leverage its partnership with the Vegas Golden Knights to secure a sponsorship with William Hill that includes access to official league data for betting purposes.
In addition to offering official betting lines, sports books also make a variety of prop bets. Statistical totals, such as the over/under on the total number of runs scored in a game, require that a full nine innings be played to have action. Similarly, First to X and Player Props require that the specified players are in the starting lineup for bets to have action.
