Jim “Mattress Mack” McIngvale, owner of the Gallery Furniture in Houston, placed a $3.5 million bet on the Astros to win the World Series. 

The Houston furniture salesman placed his insanely large bet at the DraftKings sportsbook at Scarlet Pearl casino in Biloxi, Mississippi.

If the Astros win the World Series, which they have a pretty good shot at doing, then Mattress Mack will net $7.7 million.
