The Australian Open has reached its semifinal stage, and the theme of the tournament could not be clearer. This has belonged to Jannik Sinner and Carlos Alcaraz from the very start. Both have cruised through the draw, overwhelming opponents with pace and an inevitability that has defined men’s tennis over the past two seasons. As a result, the odds entering Friday night paint a stark picture. The new generation has fully arrived, and the gap to everyone else is wide.
That reality is reflected most clearly in the pricing. Sinner is a massive favorite over Novak Djokovic, a matchup that would have been unthinkable just a few years ago. Alcaraz, meanwhile, faces Alexander Zverev, another established star who finds himself cast firmly as an underdog. Between them, Sinner and Alcaraz have claimed the last eight major titles, and this semifinal round feels less like a crossroads and more like a formality on the way to another blockbuster final.
The schedules reflect the global spotlight on these matches. Alcaraz and Zverev take the court at 10:30 PM ET, followed by Sinner versus Djokovic at 3:30 AM ET, with the tennis world tuning in to see whether experience can slow momentum or whether dominance will continue uninterrupted.

Australian Open Men's Semifinal Odds
10:30 PM ET: Carlos Alcaraz (-750) vs. Alexander Zverev (+500) Check out these Best Australian Open Odds at FanDuel Sportsbook
Alcaraz enters the semifinal as a commanding -750 favorite, and it’s easy to see why. His level throughout the tournament has been relentless, blending explosive offense with improved patience and defensive coverage. Zverev has played solid tennis to reach this stage, but he has yet to show the kind of sustained aggression required to trouble Alcaraz over five sets.
Zverev’s path likely requires serving at an elite level and shortening points, but that is a narrow margin for error against someone who thrives in extended rallies. Alcaraz’s ability to absorb pace and turn defense into offense makes it difficult for Zverev to dictate play. Unless Alcaraz dips significantly, this matchup looks tilted heavily in one direction.
3:30 AM ET: Jannik Sinner (-1500) vs. Novak Djokovic (+800) Check out these Best Australian Open Odds at DraftKings Sportsbook
Seeing Djokovic listed at +800 in Melbourne is jarring. This used to be his event, where he lifted the Australian Open trophy 10 times and built one of the most dominant résumés in tennis history. But this is now Sinner’s court. The Italian has not dropped a set all tournament and has looked untouchable from the baseline, dictating points with depth and precision.
Sinner has also won the last two Australian Open titles, firmly shifting the balance of power. Djokovic’s experience and competitive edge can never be dismissed entirely, but over five sets, it is hard to see him consistently matching Sinner’s pace at this stage of his career. The odds reflect a belief that this matchup is less about legacy and more about the present reality of men’s tennis.
Who Will Win it All?
With the semifinals set, the championship picture has narrowed dramatically. Sinner sits as the outright favorite at -135 to win the title, followed closely by Alcaraz at +120. The remaining field is priced far behind, signaling that anything other than a Sinner–Alcaraz final would be a major surprise.
Djokovic’s history in Melbourne deserves respect, and Zverev has the talent to disrupt matches on his best day, but the numbers and the on-court evidence tell the same story. This tournament belongs to the sport’s two dominant forces. If form holds, the Australian Open will once again be decided by the rivalry that has defined the modern era.
