Official betting is a type of sports betting that involves using official betting data to make bets. The data consists of stats, odds and other information collected by the official sports league for the event in question.
The data can be used to determine the final score of a game, or to place a bet on an individual player in the game. In the US, official betting is regulated by state laws. The federal Professional and Amateur Sports Protection Act of 1992 (PASPA) made it illegal for states to regulate sports gambling, but the Supreme Court overturned PASPA in May 2018.
In the aftermath of the SCOTUS ruling, the major leagues begin lobbying to compel state-regulated sportsbooks to use their own data. This effort has been led by the NBA and MLB, with their first attempt in West Virginia.
Since then, the debate over official data has continued to rage across US markets, as the industry has struggled to find a reasonable compromise between operators’ concerns about how valuable the data is and lawmakers’ desire for integrity.
The leagues have tried a number of approaches to the mandated use of their data, including private commercial agreements and legislative mandates. The latter, however, has proved a tough sell in US markets, as operators are unwilling to enter into such deals without assurances that the data will be worth it.
Lawmakers in some US states have attempted to strike a balance between the two, proposing legislation that requires use of official data for certain types of wagers while not mandating the use of official data in all tiers. The leagues argue that the compromise represents a win-win for both bettors and sportsbooks, but many operators disagree.
There are several different kinds of official betting, from prop bets to totals and runlines. These bets can be based on a variety of factors, such as the amount of runs scored and whether a team will win or lose the game.
Bettors can also place bets on the outcome of individual plays in a game, such as which player will hit a home run or how many points a team will score. The most popular of these is a wager on the team to score the most points, but bettors can also bet on whether a player will score a single, double or triple.
Another popular wager in baseball is a bet on whether or not the game will end with a walkoff hit. This market is typically offered for both the final inning and the bottom of the ninth.
The game will need to go at least 7 innings for this market to have action. If a team is ahead in the game, the totals will be settled based on the 6.5-inning rule.
During a shortened game, such as a playoff or postseason tournament game, all bets have action until the end of the game, as determined by the governing body.
The major leagues have a data arrangement with Sportradar and Genius Sports, but other providers of real-time betting data exist. As the appetite for legal sports betting grows, more and more operators will seek out these relationships. The value of the data will ultimately be driven by operators and bettors.
