The co-main event for UFC 269 saw one of the biggest upsets in the sport’s history when Julianna Pena dethroned longtime bantamweight queen Amanda Nunes with a rear-naked choke. Going into the fight, Nunes was a massive betting favorite, per usual, with Pena being a sizable underdog.
Earlier in the night, DraftKings Tweeted out that one gambler was risking $318,000 on Nunes, for a possible total payout of $349,800. If you do the math, that means whoever bet on Amanda did so at a moneyline of -1000. A couple of hours later, Pena hit a rear-naked choke to become the new champ, Nunes was one belt lighter, and DraftKings bagged 318-stacks off of one unfortunate gambler.
