According to ESPN:
If the Hail Mary pass by Seahawks quarterback Russell Wilson would have been ruled an interception by Packers safety M.D. Jennings, Green Bay — 3½ point favorites — would have won by five, covering the spread.
Instead, the replacement officials' call that Seahawks wide receiver Golden Tate had possession shifted all those who bet on the Packers to those who took the underdog Seahawks.
“Most of the customers in the sportsbook were not happy with the final call,” said John Avello, director of the race and sportsbook at the Wynn in Las Vegas. “The shift was 100 percent. After the (Seahawks) score, all bets were reversed.”
Avello's best guess as to how much money was shifted worldwide on the call? $150 million in total bets worldwide.
Mike Perry, spokesman for betting site Sportsbook.ag, told ESPN.com his estimate in the money swing on the call at the end of the game is closer to between $200 million and $250 million.
Perry said that 70 to 80 percent of the money on his site was put on the Packers, which is in line with the percentage bet in Vegas. At Mandalay Bay, the sportsbook took in about $500,000 in total bets, with about 85 percent of the money on the Packers.
