Australian Open Tennis Betting Tips for the Semifinals

Alcaraz and Sinner have almost a duopoly in the tennis world, and it’s been so for the past couple of years. Last year, they split the Grand Slams 2-2, playing in three consecutive Grand Slam Finals (French Open, Wimbledon, US Open).

This year, they’re on a collision course to meet in the AO 2026 finals, after booking their spots in the semifinals in dominant fashion. Alcaraz is facing Sasha Zverev for a spot in the final, while Sinner plays one of the greatest tennis champions of all time – Novak Djokovic.

Let’s take a look at the Australian Open 2026 Men’s Semifinals predictions and some tips below.

Semifinal 1: Carlos Alcaraz (1) vs. Alexander Zverev (3)

World number one Carlos Alcaraz meets third-seed Alexander Zverev in a trophy for the final. Alcaraz is just one trophy away from a career Grand Slam at the young age of 22. However, that’ll be a tough task despite the favorite odds, as Zverev has reached the final last year after winning a match that Novak Djokovic surrendered in the semifinal.

The Spaniard is in much better form, but you can’t count Zverev out. He defeated Alcaraz here once before in 2024, and will be looking to do the same in this one. The Australian Open 2026 Men’s Semifinals predictions are much tighter than the Alcaraz vs Zverev odds, which is supported by the head-to-head between the two players where both have won 6 times in their matches.

Zverev’s mentality is not on the same level as Alcaraz’s. That’s one of the main reasons why the German player has not won a Grand Slam yet, despite three finals. Alcaraz is a mental beast that never gives up, and we’ve watched him come from behind to defeat legends of the sport many times before.

Motivation is high for both players. Zverev is looking for another spot in the final and possibly his first Grand Slam. For Alcaraz, this is his maiden AO semifinal, and he’ll be looking to complete the career Grand Slam with a win tomorrow and in the final.

While the Spaniard is a major favorite, this is a match where overs on games are more suitable. Matches between these two may turn into a marathon, so it won’t be surprising to see any of them winning in 4 or 5 sets. The last match went to 4 – here are the highlights:

Our Alcaraz vs Zverev predictions suggest a win for Carlos Alcaraz in 4 or 5 sets. It won’t and shouldn’t be as easy as some might predict, and will almost likely feature a tiebreak or a few. But as one of the main ATP Melbourne 2026 favorites, Alcaraz should have the strength and focus to win against Zverev in the semifinal.

Semifinal 2: Jannik Sinner (2) vs. Novak Djokovic (4)

The second AO 2026 semifinal tomorrow features defending champion Jannik Sinner and Novak Djokovic. The Serbian legend has reached the final luckily, after a walkover in the last 16 (Menšík surrender), and a lucky win against Lorenzo Musetti in the quarters, which the Italian player surrendered after leading 2 sets to 0.

Djokovic had a medical timeout in that match and was obviously too banged up to play to his level. After going down 2-0, Musetti experienced a leg problem, which ultimately led to his surrender in the third set. Novak Djokovic said that he was lucky to reach the semifinals and that Musetti was the better player overall. He’ll enter the semifinal match against Sinner with doubts over his stamina and with an obvious injury, which drastically affects the Sinner vs Djokovic betting odds.

Sinner has had a tremendous Australian Open so far, and is looking toward a third consecutive trophy. He’s just ahead of Alcaraz as the main AO 2026 favorite, but no one can count Novak Djokovic out. The legendary player has won battles he should have lost many times before. The head-to-head records are in Sinner’s favor, having won 6 matches against Djokovic’s 4.

The last time they met in the Australian Open semis was in 2024, which Sinner won 3-1. He dominated the match from start to finish, winning his 3 sets strongly, while losing one tiebreak against Djokovic. Additionally, Sinner’s pace on the Melbourne Park hard courts is tough to match, and with Djokovic’s injury, a Sinner win is almost a lock.

With Jannik Sinner being a heavy favorite, better value might be found in the first set winner markets. A good option is to have Sinner as the winner of the 1^st set and the match. If Novak Djokovic can find the strength to fight back, then we may be in for a 5-set treat. But everything points to a Sinner vs Alcaraz final, as the Italian is too good on hard courts to beat, especially for an aging tennis star that’s banged up.

Betting Strategy & Market Insights

The sports betting BetPlays section features a number of tennis betting markets for the semifinals ahead. At the moment, Jannik Sinner and Carlos Alcaraz are favorites to reach the final and win the first Grand Slam of the season.

However, their winner odds don’t offer a lot of value, which has to be looked at elsewhere. The underdog spread on Zverev certainly providers more than solid odds. Prop bets do, too, especially in these tight matches which might feature several tiebreaks.

For Zverev and Sinner, players should also take a look at the number of aces. Both players serve much stronger than their opponents, and this is a market that can deliver strong returns.

Alternatively, live betting will allow bettors to react to momentum swings and back up a favorite in many statistical categories. BetPlays’ live betting section offers live streams of the top matches, including the AO 2026 semis, so Canadian bettors can follow the action and make more accurate predictions.

Final Thoughts on the AO 2026 Men’s Singles Semis

After two weeks of action, the sun is setting over Melbourne Park. The stage is set for a historic conclusion with the semifinals, and we might be witnessing history in the final two steps.

Carlos Alcaraz is on a path to a career Grand Slam, while the King of Melbourne Novak Djokovic may be playing the last tournament. Zverev and Sinner have strong chances to win their respective finals, so drama is guaranteed early on Friday.

For Canadian bettors looking for Australian Open betting tips, the money is on a youth takeover. Sinner an Alcaraz remain the top ATP Melbourne 2026 favorites, but thin margins in the Alcaraz vs Zverev predictions suggest that upsets aren’t entirely off the table. If the German can maintain good serving percentages, the Spaniard may be in for a surprise.

The Sinner vs Djokovic betting odds reflect a changing of the guard. However, betting against Novak Djokovic is never a smart idea, especially in a semifinal. He’s beaten the odds many times before, and may do so again.
