Abstract On May 14, 2018, the U.S. Supreme Court effectively allowed single-game sports wagering in America. The current U.S. sports gambling market is estimated at somewhere between $67 billion and $400 billion—and with legalization is expected to grow larger. The social, economic, and sports changes already have begun: thirteen states have legalized sports gambling; there is a sports stadium named after a bookmaker; and a television channel dedicated to 24/7 of coverage of the sports gambling market has been launched. However, few analysts have tried to estimate which American sports are most at risk from the gambling related match-fixing that has plagued many international sports leagues. Using a wide-range of interviews with gambling and match-fixing insiders, this paper proposes an indicator to predict the vulnerability of a sports league to match-fixing, along with seven specific factors that lead to corruption.
