Large bets, as much as $500,000, showed up on Gennady Golovkin at Las Vegas sportsbooks in the final hours before Saturday's title fight against Canelo Alvarez. They would all have to be refunded, after a controversial decision left both bettors and bookmakers disappointed and confused.
Heading into the decision, oddsmakers believed Golovkin had won the fight. International sportsbooks had Golovkin as high as a -500 favorite when live betting on the bout closed.
But when the decision was announced, judge Adalaide Byrd had seen things differently. She had Alvarez an easy 118-110 winner, a stunning difference from the cards from judges Dave Moretti (115-113 Golovkin) and Don Trella (114-114). The fight was ruled a split draw.
Shortly after the decision was given, lines formed at sportsbooks, with bettors looking for refunds. Straight bets on the winner of the fight were refunded in Las Vegas. Wagers on the method-of-victory props, which included an option to bet draw, were not refunded.
