Amanda Nunes is coming back to the UFC as the betting underdog. BetOnline Sports and Casino opened women’s bantamweight champion Kayla Harrison as a -190 favorite for their title fight at UFC 334, with Nunes sitting at +161, according to odds reported by Yahoo Sports and Sherdog. The bout is the co-headliner on the promotion’s annual Madison Square Garden card, set for Nov. 14 in New York.
Here’s what those numbers mean. At -190, you’re laying $190 to win $100 on Harrison, which works out to an implied win probability of about 65.5%. The +161 on Nunes pays $161 on a $100 bet and implies roughly 38.3%. Add them together and you get about 103.8%. That extra 3.8% is the book’s cut, and it’s why the house never needs a lucky night.
The detail that jumped out of the Yahoo report is the last time “The Lioness” walked into a completed UFC fight as an underdog. That was against Cris Cyborg at UFC 232 in 2018, and Nunes knocked her out in 51 seconds. One fight from 2018 doesn’t decide what happens in 2026, but it does tell you the market has been wrong about her before, and loudly.

The rest of the main card
The main event has heavyweight champion Ciryl Gane defending against the unbeaten Josh Hokit. Gane opened at -243 with Hokit at +203, so the book gives the champ around a 70.8% implied chance. That’s a wider gap than the co-main, which tells you how the oddsmakers rate Harrison’s hold on her belt compared with Gane’s.
The closest line on the main card belongs to the middleweight fight between Caio Borralho (-120) and Yousri Belgaroui (+103). That’s about as near to a coin flip as you’ll see with juice attached. Uros Medic opened at -165 over Kevin Holland at +140.
Then there’s the outlier. Flyweight prospect Bilal Hasan is a -950 favorite against Luis Gurule, who sits at +650. Laying -950 means risking $950 to win $100, an implied probability of roughly 90.5%. That number is going to end up in a lot of parlays by fight week, stapled next to Gane and Harrison by people who think three favorites equals free money. I’ve built that ticket. I’ve watched it die on the last leg. Twice.
My take: the most interesting price on this card is Nunes at +161. I don’t love fighters returning at short odds, and that’s exactly why this line is worth a look. The books are asking you to pay a premium to back the champion and offering a discount on the woman who made a career out of embarrassing that kind of math. If you think Nunes has a better than 38% shot at MSG, the value is on her side of the sheet. Watch where this number sits as the Nov. 14 card gets closer, because if money moves toward Nunes, that +161 won’t be around for long.
