DANA White won a stunning $100,000 (PS74k bet) after Canelo Avarez's amazing KO of Caleb Plant.
After overseeing a stellar card in which Kamaru Uman beat Colby Covington, the UFC chief placed a huge wager on the P4P king just before their undisputed super-middleweight world title fight in Las Vegas.
After Canelo Alvarez's victory over Caleb Plant, Dana White is PS30,000 more wealthy
White won the jackpot with $41k (PS30k), after backing the Mexican to win through knock-out.
Canelo, 31 years old, struggled through the fight but sent Plant to the ground in the 11th round.
He is the undisputed champion of super-middleweight in history and has earned at least PS30m.
White is also richer because of it.
The 52-year old, who was watching the fight from the front row at UFC 268 while sitting in front of UFC 268 on TV, admitted that he is a degenerate' gambler after he lost a $1MILLION (PS741k), boxing bet in 2007.
White, a Las Vegas-based blackjack player, loves to take a bet on sports.
In February, he told ESPN: "Oh my God. What was the name of the child? Jermain Taylor.
"And who did he fight?" This is because of the ass-whooping that I did. Kelly Pavlik, a tall, white, tall kid from Ohio, was his opponent.
"It cost me $1million to bet on Taylor, and he was destroyed."
"It was my first $1m dollar bet because I was confident Taylor would win that fight."
White was born in Boston and moved to Sin City following a fight with Whitey Bulger, a crime boss.
His love for gambling began in Vegas.
He stated, "I would say it's just about time. It's something I enjoy. It's evident that people love it.
It makes watching whatever you are watching much more enjoyable and interesting. But I'm originally from Vegas.
"I love table games too much. If you don't get it, I'm a degenerate. Yes, I am a degenerate. I love to gamble."
