Exclusive | Mattress Mack lays $516K hammer on the Astros to win $13 million at Kalshi

Mattress Mack is back — throwing around cash and beds to boot.The famous sports bettor and furniture salesman is all in on his beloved and native Astros to win the World Series now that they have officially made the playoffs.After marketing for roughly two months an Astros to win the World Series promotion where customers who spend $4,000 or more at his Gallery Furniture store get their purchases refunded if the team wins the Fall Classic, Jim “Mattress Mack” McIngvale has officially put his money on Houston with a new operator.Mack tells The Post he has laid $516,000 on the Astros to win the World Series, with a potential payout of $13 million if they do – and he’s gone to prediction market Kalshi to facilitate.“Well, we’ve been running the promotion for a while, so we have some built-up liability already,” Mack tells The Post.“Baseball is a very random game, and the Astros have more home runs than anybody”The furniture salesman added that he already has a big liability here despite Houston wallowing for much of the season.
