Jim “Mattress Mack” McIngvale, owner of Houston-based Gallery Furniture, took home $75 million — widely reported to be the largest payout in the history of sports betting — when the Houston Astros won the franchise’s second World Series title with a 4-2 victory against the Philadelphia Phillies in 2022. Based in Texas, McIngvale made a series of bets amounting to $10 million on the Astros to win the World Series.
