With billions of passionate fans and comprehensive domestic leagues operating across every continent, matches ranging from the English Premier League and UEFA Champions League to the FIFA World Cup generate staggering betting turnovers through online sportsbooks and physical betting terminals. In the United States specifically, American football and the National Football League command the highest domestic handle, but on a worldwide scale, association football reigns supreme in total betting volume.
