We have written about Houston-area furniture store magnate and frequent big bettor Jim "Mattress Mack" McIngvale a few times in this space. He makes huge wagers as a hedge against potentially large money-losing promotions at his Gallery Furniture stores. "Mattress Mack" is at it again as he recently dropped $2 million on Caesars Entertainment's William Hill Indiana Sportsbook App on his hometown Astros to win this year's World Series at a price of +1000. Should the Stros win it all for the first time since 2017, McIngvale would win an American betting record $22 million ($20 million and the $2 million wager back).

"This is a potentially historic bet, and it's one that we love to take," said Eric Hession, Co-President of Sports for Caesars Entertainment.  "We pride ourselves on our flexible limits in our sportsbooks and sports betting apps. This wager certainly makes baseball season a little more exciting for us, and we're looking forward to seeing how that plays out."

The Los Angeles Dodgers (+360), Chicago White Sox (+700), San Diego Padres (+850) and New York Mets (+850) are the only teams currently with shorter World Series odds at William Hill than the Astros, who entering Wednesday have the best record in the American League at 45-28 and the best run differential in all of baseball at +122.

Houston is in Baltimore on Wednesday night on an MLB-high nine-game winning streak and just swept the very good White Sox four games over the weekend at Minute Maid Park. In fact, eight of the Astros' nine wins during this run are by double digits. They are more than capable of winning a title – although they might need some starting pitching help by the July trade deadline.

"It's very cool that William Hill took that large of a futures bet," McIngvale said. "Kudos to William Hill for stepping up and taking that big bet. I've done a lot of bets with William Hill, and they've always been great to me. The execution has always been great."

According to ESPN, McIngvale also wagered $1 million on the Astros with FanDuel in Indiana in addition to $250,000 on DraftKings and $100,000 with The Score sportsbook in Colorado. Overall, he has placed wagers worth $3.35 million that would net him a return of $35.6 million.

Yes, there is a promotion at his Gallery Furniture stores ongoing: Customers who spend at least $3,000 over the next several months will receive their money back if the Astros win the World Series.

Back in February, McIngvale dropped a $3.46 million bet on the Tampa Bay Bucs at +3.5 (he bought the extra half-point) to cover the spread in Super Bowl 55 over the Kansas City Chiefs, and Tom Brady's team won outright. 

He also wagered $3.5 million for the Astros to win the 2019 World Series during that season, but Houston blew a 3-2 lead and lost in seven to Washington. Reportedly, he lost a total of $13 million in wagers when the Astros lost to the Nationals in Game 7. A win would have netted him $25 million overall.

Before this year's men's NCAA Tournament, McIngvale wagered $1 million on the University of Houston at +900 to win the national title. The Cougars were blown out in the Final Four by eventual national champion Baylor.
