Businessman Jim 'Mattress Mack' McIngvale is looking to cash in on massive bets placed on his hometown Houston Astros.

McIngvale, 72, reportedly placed a $2 million futures bet wager on the Astros to win the 2023 World Series at +600 odds at DraftKings Sportsbook, according to USA TODAY, as well as $1.9 million futures World Series bet on the Astros at +600 odds at Caesars Sportsbook, according to FOX Sports' Patrick Everson. In total, the businessman would have a cashout exceeding $23.4 million on $3.9 million placed.

Last year, McIngvale won the reported largest legal bet in U.S. sports betting history after placing $3 million on the Astros to win the 2022 World Series at 10-1 odds at Caesars Sportsbook, which resulted in an approximately $75 million payout, ESPN reported at the time.

"What can we say? We just wrote the biggest check in sports betting history to Mattress Mack for $30,000,000," said Ken Fuchs, chief operating officer for Caesars Digital, in a press release on behalf of the company Saturday night.

McIngvale -- who gets his nickname from his popular Houston based furniture store -- had also won an estimated $7 million in bets on the Astros throughout the 2022 MLB season at various sportsbooks, which included average payout odds of +750. The entrepreneur did, however, pay back some of his winnings to his customers who participated in spots betting promotions at his Gallery Furniture store.
