What the Odds Say
Amanda Nunes and Kayla Harrison meet on Saturday, November 14 at 9:00 PM PST, and the betting market has a clear lean. Across major sportsbooks, Harrison is the favorite, with moneylines ranging from -192 at Pinnacle to -278 at Grosvenor. Nunes is the underdog, with her best available price at +168 at Bovada and +165 at BetOnline.ag and Coolbet.
The consensus is firm: Harrison is expected to win more often than not. But the spread across books tells a more nuanced story, and that range is where opportunity sits.
Breaking Down the Implied Probabilities
At Pinnacle, the sharpest book in the market, Harrison sits at -192. That translates to an implied win probability of roughly 66%. Nunes at +162 on the same book implies about 38%. Because these are raw, vig-included prices, the two will add up to more than 100% combined.
At the other extreme, Grosvenor has Harrison at -278, implying closer to 74%. That gap signals the market has not fully settled into a tight consensus on where this line belongs.
For Nunes, the best available price of +168 at Bovada implies roughly 37% probability. Her worst price of +138 at Grosvenor implies only about 42% in reverse terms.
