Mattress Mack is back with another monster bet this weekend. 

As the Kentucky Derby prepares to race on Saturday, Houston retailer Jim "Mattress Mack" McIngvale is going all-in on the odds-on favorite, Essential Quality, placing a $500,000 wager on the No. 14 horse.

MATTRESS MACK JUST BET $500K ON THE KENTUCKY DERBY 🚨 Mack’s taking Essential Quality. And he’s not done betting... https://t.co/8RDFAgsipX

As of Friday afternoon, Essential Quality's odds are up to 4-5 (win $4 for every $5 bet) with Rock Your World coming in a 5-1 and Hot Rod Charlie at 9-1. 

Trained by Louisville native Brad H. Cox, Essential Quality enters the starting gates with five first-place finishes dating back to last September, including one at Churchill Downs. Now, he's got Mattress Mack jumping on the bandwagon a day before the race. 

Mack's last major bet saw the Texan drop $1 million on Houston to win the NCAA tournament at 9-1. That didn't quite pan out too well with the Cougars falling in the Final Four to eventual-champion Baylor. 

He's hoping the run for the roses goes a bit better this time around.
