In the six years since the U.S. Supreme Court cleared the way for states to offer sports betting, each successive year has set a record for the amount of money wagered legally.
Another new high-water mark of close to $130 billion is expected by the end of 2024. It coincides with what has been a year of reckoning rocked by high-profile scandals.
The bad publicity included former Toronto Raptors player Jontay Porter's lifetime ban from the NBA after a league investigation found he disclosed confidential information to bettors and faked ailments in games to fix proposition bets related to his own performance. There was also the case of Ippei Mizuhara, the former interpreter for Shohei Ohtani who pleaded guilty to bank and tax fraud in a case in which prosecutors said he stole nearly $17 million from the Japanese baseball star to pay off illegal gambling debts.
Ohtani was cleared of any wrongdoing, but his proximity to such malfeasance heaped negative attention on baseball's biggest name.
"When you have people betting on sports, you have people trying to corrupt sports — they go hand in hand,'' said John Holden, an associate professor at Indiana University who conducts research on gambling and college athletics policy. ''So, these were things that were going to happen. I think it's opening people's eyes that the legalization of sports betting in the U.S. wasn't going to be the exception to the problems that come with sports betting everywhere else in the world.''
Porter was on a two-way contract at the time of his violations, which meant he could bounce back and forth between the Raptors and their G League affiliate. His salary was $410,000, and a standard NBA contract would have been more than $2 million. In pleading guilty to federal conspiracy charges in July, Porter acknowledged wrongdoing, saying he did it ''to get out from under large gambling debts.''
''Certainly, prop bets, depending on how precise they are, lend themselves to more shenanigans than other kinds of bets," NBA Commissioner Adam Silver said in May.
In light of Porter's banishment, BetMGM Sportsbook said in October that it would not take NBA prop bets on players on two-way or 10-day contracts. It joined several others taking this action, including U.S. sportsbook giants DraftKings and FanDuel, as well as ESPN BET.
