Australian Open Odds | Sabalenka Huge Favorite Over Keys; Sinner Expected To Beat Zverev
The Australian Open finals are set, and both defending champions are expected to win again Down Under.
Aryna Sabalenka is going for her third straight title in Melbourne, while Jannik Sinner will hope to win his second. Both are and have been the Australian Open odds favorites across our best sports betting sites from the outset.
Sabalenka will play Madison Keys, who advanced to her first final in eight years by beating Iga Swiatek. On the men's side, Sinner will face the No. 2 seed and our player to watch from the start of the tournament, Alexander Zverev, on Sunday.

Men's Australian Open odds favorites
Jannik Sinner Australian Open odds (-275)
The defending champion is the prohibitive favorite to repeat Down Under, and for good reason. As expected, Sinner wiped the floor with Ben Shelton, winning in straight sets to book his place in the final against Zverev.
Zverev is one of the few players on tour who has gotten the better of the Italian, winning four of six previous meetings. However, Sinner won the last time these two played in 2024.
Sinner has been in the best form since last year's Australian Open, but he won't have it easy in this final. A winning bet would profit just $3.64.
Best odds: -275 via bet365 | Implied probability: 73.33%

My 2025 Australian Open men's player to watch
Alexander Zverev Australian Open odds (+225)
Zverev got fortunate in his semifinal match against Novak Djokovic, with the Serbian legend forced to retire due to an injury he couldn't overcome. The German No. 2 seed will now face the world's top seed in his third Grand Slam final and first Down Under.
Zverev has dropped just two sets en route to Sunday's final and will be the slightly fresher of the two. He's also beaten Sinner in both Grand Slam meetings on hard court. Zverev's only defeat in a major to Sinner came on clay at the French Open in 2020.
I have been bullish about the German 27-year-old since last year's US Open final, and I won't stop now. His +225 odds offer exceptional value. Plus, he's going for his first Grand Slam triumph, which might provide just enough inspiration to secure the upset.
Best odds: +225 via BetMGM | Implied probability: 30.77%

Australian Open women's odds 2025
Odds from our best sportsbooks as of Jan. 24.
| Player | DraftKings | FanDuel | BetMGM | Caesars | bet365 |
|---|---|---|---|---|---|
| Aryna Sabalenka | -330 | -345 | -325 | -350 | -350 |
| Madison Keys | +250 | +220 | +270 | +250 | +275 |
Women's Australian Open odds favorite
Aryna Sabalenka Australian Open odds (-325)
Sabalenka is one win away from three straight Australian Open titles. If she beat Keys, she'd join the rarified air of Martina Hingis, Monica Seles, and Steffi Graf as three-peat winners.
The gregarious Belarusian faces Keys in the final, who she's beaten in four of five previous meetings. Keys' solo victory came in 2021 in Berlin.
I've been a Sabalenka proponent since I can recall, and I backed her after she won the US Open in September. There's no way I'm changing my tune now. I hope you got her at plus-money odds previously, as a winning $10 bet now will only profit $3.08.
Best odds: -325 via BetMGM | Implied probability: 76.47%
2025 Australian Open women's finalist
Madison Keys Australian Open odds (+275)
You've got to be impressed with how Keys acquitted herself against Swiatek, who hadn't dropped a set prior to the semifinal tilt. Swiatek had a match point but was unable to finish off the resilient American, whose power from the baseline could pose some problems for Sabalenka.
If she plays as well as she did against Swiatek, we'll have ourselves a grandstand final. Either way, I can't see Keys pulling off the sizable upset. However, Mike Spector backed the underdog in his Sabalenka vs. Keys prediction and odds. A winning $10 bet will profit $27.50.
Best odds: +275 via bet365 | Implied probability: 23.26%
