What is Vig?
Vig, short for vigorish and sometimes called juice, is the built-in commission or fee that sportsbooks charge for accepting your bet. This fee is not shown as a separate charge but is embedded within the odds themselves, ensuring that the bookmaker profits over time, regardless of who wins or loses the event.
