I had to refresh my screen three times when the lines dropped for UFC 324.
Seeing a “plus sign” (+) next to Amanda Nunes‘ name feels like a glitch in the matrix. For a decade, the “Lioness” wasn’t just a favorite; she was unbettable chalk. We are talking -600, -1000 lines. She was the woman who retired Ronda Rousey, Cyborg, and Miesha Tate.
But here we are in 2026. Nunes is coming off the couch, and the books have installed Kayla Harrison as the clear favorite to spoil the return of the GOAT.
Is this a trap? Or is this the classic “Passing of the Torch” moment where the books are begging us to bet on the aging legend one last time?
Let’s break down the weirdest line of the year.
📊 The Odds Board: A Rare Sight
Odds provided by BetUS. Lines subject to change.
| Fighter | Opening Line | Current Line | Implied Win % |
|---|---|---|---|
| Kayla Harrison | -150 | -165 | 62.3% |
| Amanda Nunes | +120 | +135 | 42.6% |
The Story of the Line: The books opened Harrison at -150, and the early sharp money pushed it straight to -165. The market is saying loud and clear: “We don’t trust a retired fighter against a prime killer.”
🦁 The Case for Amanda Nunes (Why She is +135)
Why is the greatest female fighter of all time an underdog? Two words: Inactivity and Hunger.
Nunes has been living the good life. She retired, enjoyed her family, and seemingly left the sport behind. Coming back at age 37 (turning 38 soon) is historically a disaster. We saw what happened to Cejudo. We saw what happened to Fedor. The sport moves on fast.
The oddsmakers are banking on three things:
- Ring Rust: You can’t replicate fight speed in the gym.
- The “Bank Account” Effect: Nunes is rich. Does she still have that savage desire to eat a punch to give one?
- Harrison’s Size: Nunes used to bully 135ers. She won’t bully Kayla Harrison.
But here is the counter-argument: Amanda Nunes hits harder than anyone Kayla Harrison has ever seen. Harrison has been dominating girls who were scared of her Judo. Nunes isn’t scared. If Harrison rushes in for a clinch (like she did against Holm), Nunes has the check hook to put her lights out.
🥋 The Case for Kayla Harrison (Why She is -165)
Kayla Harrison is not just a “Judoka” anymore. Since cutting to 135 lbs, she has looked like a monster.
- The Physical Prime: Kayla is in her absolute athletic peak.
- The Grappling Gap: Let’s be honest—if Kayla gets her hands locked around anyone’s waist, they are going for a ride. Even Nunes.
- The Momentum: While Nunes was retired, Kayla was active, cutting weight, and staying sharp.
The books are pricing Harrison as the “New Era.” They believe her top control is too heavy, and if she gets Nunes down early, the gas tank of the returning legend will empty by Round 2.
🥊 The Stylistic Matchup: Violence Guaranteed
This isn’t a chess match. This is a car crash.
If Harrison Wins: It looks like a mauling. She eats one or two shots to close the distance, trips Nunes, and spends 15 minutes grinding her face into the canvas. It won’t be pretty, but it will be dominant.
If Nunes Wins: It looks like the Cyborg fight. Harrison gets overconfident, tries to trade in the pocket, and gets caught by the “Lioness” right hand. Or, Nunes stuffs the first two takedowns, Harrison panics, and Nunes picks her apart on the feet.
💰 The Verdict: Where is the Money?
I struggle to bet against Amanda Nunes at plus money. It feels like betting against Tom Brady or Michael Jordan.
However, the “Smart Money” rule in MMA is simple: Fade the returning legend.
The sport waits for no one. Kayla Harrison has been active, she is hungry for legacy, and she is physically massive for the weight class. The -165 line is actually… fair.
But I’m not betting the Moneyline.
The best value on the board is the OVER 2.5 ROUNDS (-130).
- Nunes has the experience to survive the early storm.
- Harrison respects Nunes’ power too much to rush in recklessly.
- Both women are durable.
I expect a tentative Round 1, a grindy Round 2, and the bet to cash midway through the 3rd.
Official Prediction: Kayla Harrison via Decision. Best Bet: Over 2.5 Rounds (-130).
Feeling risky? If you think the GOAT has one last roar in her, +135 is insane value. Just know that you are betting against Father Time, and he is undefeated.
