Official betting is a type of wagering that requires the use of official data provided by a sports league. This data is used to determine the odds of a particular result.

Major American sports leagues are heavily involved in the industry, with teams and clubs having sponsorship deals with bookmakers. These deals often come with access to live stats, in-play betting and data.

The NFL playoffs offer a unique once-a-year opportunity to place a bet on a team to win the Super Bowl. The bracketed path for a team to qualify includes four first-round Wild Card games, followed by three Divisional rounds and finally one Super Bowl.

Betting on football matches is extremely popular in the US. Most states allow some form of legal sports betting, and a number of top betting sites offer NFL action throughout the season.

There are many types of official bets, including parimutuel wagering, totalizators and if bets. The latter type of bet is a flexible-rate bet that pays out according to the percentage of total exchange that each possible outcome has received in real time.

While a majority of bettors place their money on the winner of an event, some place their bets on specific outcomes or scores. These bets are called if bets, and they are available at a variety of bookmakers.

Since the US Supreme Court overturned PASPA in 2018, states have been individually deciding how to regulate sports betting. Some of them have adopted a neutral stance, while others have embraced the legal industry. A key element of this is the debate over the role that official league data should play in state-regulated sports betting.
