Even before his significant win, McIngvale was already living comfortably. His mattress business was quite successful, as evidenced by the substantial sum of money he initially used to place the wager.

Astros fans were elated as the team clinched a second title as Yordan Alvarez's Game 6 homer ousted the Philadelphia Phillies.
