Reigning bantamweight champion Kayla Harrison puts her belt on the line against Amanda Nunes at Madison Square Garden tonight. The main card starts at 9 p.m. ET, with this five-round title fight going on second to last.

Nunes has not competed since retiring in June 2023. Harrison last appeared in June 2025, so both women are stepping back in after real time away.

That layoff is the pivot point for the whole card. Here is my final Harrison vs Nunes prediction, best prop bets and UFC 334 co-main odds.

Final Harrison vs Nunes Prediction

• Winner prediction: Kayla Harrison retains the bantamweight title

My forecast is Harrison defending the crown. The case for her is strongest on the mat. I prefer the submission price to laying -169 on her to win outright.

Harrison does not need the championship rounds either. She tapped Julianna Peña with a second-round kimura at 4:55 and choked out Holly Holm in the second at 1:47, so the finishing instinct shows up early.

Nunes is the better striker by a distance, and nobody should pretend otherwise. If this stays upright for long stretches, the power and the pedigree swing it her way in a hurry.

How this forecast loses: Harrison gets careless closing the distance and eats a right hand from a fighter who has ended plenty of nights with one. The chalk goes up in smoke before any grappling happens.

Harrison vs Nunes Odds

Odds as of Friday evening, Nov. 13 at BetMGM and subject to change. Check out the best UFC betting apps for UFC 334 on Saturday.

Harrison at -169 and Nunes at +140 come out to roughly a 60 percent win probability for the champion once the sportsbook’s margin is stripped out of both sides. That is a real edge but not a commanding one.

The total is the number worth studying. At 3.5 rounds, the Under needs the fight to finish before the midpoint of round four, which gives you more than three full rounds of runway. New users can claim the BetMGM promo code and score a bonus to use on this fight.

Harrison vs Nunes Best Prop Bets

One note before you play these. A Harrison submission in the first three rounds cashes both tickets at once, so consider sizing them as one correlated position rather than two separate bets.

Prop 1: Under 3.5 Rounds

• Best Prop Bet: Under 3.5 Rounds (-125 at BetMGM)

Neither of these women makes a habit of leaving it to the judges. Harrison closed out both Peña and Holm in the second round, and Nunes has ended fights early for most of her career.

A slower first round would leave less room for the Under. My case for an early finish depends on Harrison forcing the first extended grappling exchange before Nunes settles into a rhythm.

How this forecast loses: Nunes grapples defensively, pins Harrison to the fence and turns this into a five-round stall. The Under dies slowly.

Prop 2: Kayla Harrison by Submission

• Best Prop Bet: Kayla Harrison by Submission (+150 at BetMGM)

Harrison’s transitions are the sharpest part of her game, and she forced the tap in round two against both Peña and Holm. That is the specific skill this matchup rewards.

Nunes has been submitted before, by Peña at UFC 269, when she was dragged into exactly this kind of fight. At +150 you are getting better than even money on the likeliest stoppage.

How this forecast loses: Harrison cannot bridge the distance, the fight becomes a kickboxing match, and she is outgunned there.
