The first Grand Slam tournament of 2025 is officially underway, with the Australian Open kicking off over the weekend for fans in the United States. Melbourne has welcomed the biggest stars in men’s tennis, including Jannik Sinner, Carlos Alcaraz, Novak Djokovic, Alexander Zverev, and Daniil Medvedev. Sinner enters as the defending champion, having claimed his inaugural major title at last year’s event. However, he’ll face fierce competition from a highly motivated field eager to dethrone him.
Sinner tops the 2025 Australian Open betting odds at +125, reflecting his status as the favorite. Close behind is Carlos Alcaraz, who captured the French Open and Wimbledon titles in 2024, listed at +350. Novak Djokovic, a 10-time Australian Open champion, follows at +550.
Alexander Zverev (+800), Daniil Medvedev (+1400), and Taylor Fritz (+2800) round out the top contenders. Medvedev, the 2021 US Open champion, has twice come agonizingly close to winning in Melbourne, having held a two-set lead in the final on both occasions. Meanwhile, Fritz aims to build on his momentum from a runner-up performance at last year’s US Open.

| Jannik Sinner
It’s difficult to look past world number one Jannik Sinner, given his composed and consistent approach on the court. The Italian has become a regular fixture in Grand Slam semi-finals, handling high-pressure situations with minimal fuss. Last year, Sinner was dominant, cruising through the tournament without dropping a set until his clash with Novak Djokovic. He eventually dropped only three sets in total, including an incredible comeback from two sets down to defeat Daniil Medvedev in the championship match. In his 2025 opener, Sinner delivered a solid performance, defeating Chile’s Nicolas Jarry 7-6, 7-6, 7-1. However, with Medvedev in the same half of the draw, there’s potential for a rematch of last year’s dramatic final. While Sinner will be tough to beat, his odds may not offer great value. Novak Djokovic, chasing yet another piece of tennis history in Melbourne, could present a more compelling option for bettors. Novak DjokovicNovak Djokovic remains a strong contender to expand his Grand Slam tally if everything falls into place. Despite entering the Australian Open following a quarter-final exit at the Brisbane Open, where he was defeated by Reilly Opelka, Djokovic is bringing fresh energy to Melbourne with a new coach in his corner—none other than Sir Andy Murray. Remarkably, Murray was still competing in the tournament just a year ago, making this partnership a headline-grabber. This dynamic duo has sparked media buzz, and Djokovic is listed at +550 to clinch his record-breaking 25th Grand Slam title, which would move him past Margaret Court’s long-standing record. At 37, Djokovic last triumphed in Melbourne in 2023 but reached the semi-finals last year, where he was defeated by eventual champion Jannik Sinner. In this year’s campaign, Djokovic began his journey against American wildcard Nishesh Basavareddy and could face Carlos Alcaraz in a highly anticipated quarter-final clash. Alcaraz, aiming to secure his first Australian Open crown, is looking to complete a career Grand Slam.
