Sports betting has exploded since the US Supreme Court struck down PASPA in 2018. With more states legalizing regulated sports wagering, questions over what’s legitimate and what isn’t have emerged. One issue that’s been the subject of controversy is official betting, which involves placing bets on a specific event using data from a league or other source.

The official betting rules of a sport determine how the odds are set and how bets are graded. Some bets are placed on individual players and teams, while others involve a more broad scope of action in the game. Regardless of the type of bet, the official betting rules of a sport must be followed in order to ensure the integrity of the game and the fairness of bets.

A key element of the official betting rules is ensuring that all bets are made with the latest available information. This means that bettors must make sure the results are final before making a bet, or it will be considered void. Additionally, the official betting rules of a sport require that bets on a specific outcome must be officially announced before they can be accepted or paid out.

The rules also address how a bet is graded when stats change after the fact. For example, a fielder may have reached first base on an error during a game but the official scorer may later change it to a hit. In such cases, the sportsbook may adjust the bet’s grade and pay winning bettors accordingly.
