The Houston furniture salesman known as "Mattress Mack" is betting big on the Bengals to win Super Bowl LVI against the Rams in Los Angeles.
Jim McIngvale placed more than $4.5 million in bets on the Caesars Sportsbook app in Louisiana on the underdog Bengals to win on the moneyline at +170 odds - meaning the bet would net more than $7.7 million if Cincinnati wins the game.
It's believed to be the largest wager he's ever placed, and Caesars Sportsbook tweeted that it's the single largest legal mobile wager ever.
McIngvale said he had to drive across the Texas border into Louisiana - because mobile sports wagering isn't legal in Texas - pull over at a gas station, and make about 20 wagers of $200,000 each through his account with Caesars Sportsbook, according to multiple reports.
