In 2025, the Grand Slams of men’s tennis were dominated by the sport’s new superstar duo of Carlos Alcaraz and Jannik Sinner, while four different champions were crowned on the women’s tour.
The season opened with Madison Keys taking the Australian Open, followed by Coco Gauff winning at Roland Garros, Iga Świątek dominating at Wimbledon, and Aryna Sabalenka claiming the US Open.
With the new season starting up Down Under on 18 January, here are some predictions for the 2026 Grand Slams.
Australian Open Winners 2026
Having waited until the final opportunity to secure another Grand Slam, Sabalenka looks primed and ready to reclaim the Australian Open to start the 2026 season hot.
She was ousted by Keys in the final to deny a rare triple, but this remains the Belarusian’s preferred surface and her supremacy showcased throughout 2025 kept her well ahead atop the WTA rankings.
Even so, the sports betting lines only see Sabalenka as the narrow favourite. She’s at 2/1 with Świątek just behind at 6/1. The reigning champion, Keys, gets odds of 7/1. With the odds behind her, Sabalenka is predicted to win.
Novak Djokovic, the record leader for Grand Slam victories, is still in the picture for the 2026 Australian Grand Slam at 15/2, but most predict that the two-time champion eyeing up his third title Down Under will come out on top.
Now 38-years-old, Djokovic might prove to be Sinner’s closest competitor as the Italian seeks to be the first to win three on the bounce in Australia since the Serbian did so himself.
Bundle in that Alcaraz – even while seemingly being on the up on hard courts – has famously struggled in Australia. Sinner’s 1/1 odds certainly back the prediction that he’ll claim the first men’s Grand Slam of 2026.
French Open Winners 2026
Many are seeing Świątek’s 2025 season on clay as a blip. The 24-year-old Pole has more than earned the title of being the ‘Queen of Clay,’ having already claimed the French Open four times.
The tennis odds back a return to dominance on this surface at 9/4, but given that Sabalenka was the one to end her time at Roland Garros in 2025, the world number one is close behind at 11/4.
Even with Sabalenka seemingly being in such good form and the defending French Open Champion, Gauff, likely to go far, Świątek looks primed to come out on top as she has done so often in previous years.
On the men’s side, there are only really two names in consideration. Sinner is in with a shot at 7/4 to get revenge after the epic 329-minute final of last year, but Alcaraz remains the best on clay.
That said, the Spaniard did have a slight added advantage over his foe last season as Sinner only recently returned from a three-month ban. Even so, at odds of 8/5, Alcaraz is predicted to win the French Open again.
Wimbledon Winners 2026
Had Świątek not seen her clay season come to an abrupt end, she may not have turned her focus to grass and ultimately take the Wimbledon crown.
She obliterated Amanda Anisimova in the final while Sabalenka fell one round short for a third time. Wimbledon remains the only Grand Slam in which she hasn’t made it to the final, but the odds favour her to win it at 3/1.
Świątek sits a bit back at 4/1, partly because her clay season is expected to be more extensive in 2026. Add in that a new champion has been crowned in each of the last eight finals, and Sabalenka gets the call for Wimbledon.
Back in 2023, Alcaraz finally broke the four-year winning streak of Djokovic on the grass of Wimbledon. The Serbian was part of many of the greatest Wimbledon finals ever, and didn’t bow out quietly.
He met the upstart Spaniard in 2023 and 2024 in the final, before being crowded out by Alcaraz and Sinner in 2025. Last time out, Sinner came out on top, ending Alcaraz’s hopes of taking the Grand Slam three years running.
Sinner is just ahead in the odds at 6/4 with Alcaraz back at 13/8, but the prediction here goes to Alcaraz getting his third Wimbledon trophy.
US Open Winners 2026
Over the last couple of years, Gauff has been a favourite to take the US Open, but the 2023 champion has fallen very short in each of the last two years.
In bowing out in the fourth round twice, Gauff made the path to Sabalenka’s double that little bit more straightforward. The Belarusian is now dominant, very confident in the US, and favoured to win it again.
According to the odds, Sabalenka is marginally ahead at 12/5 to Świątek’s 4/1, with Gauff way out at 11/1. Even if Gauff returns to form, Sabalenka is predicted to add another Grand Slam at Flushing Meadows to end the 2026 season.
Taking place at the end of the season, the US Open regularly finds itself a new winner to defy expectations. Since Roger Federer’s five-year run of complete dominance ended in 2009, there have been ten different winners without a single back-to-back men’s champion.
The last four instalments have traded the trophy from Alcaraz to Djokovic to Sinner and back to the Spaniard. For 2026, Sinner is favoured at 7/5 while Alcaraz is at 2/1 to become the first back-to-back winner in 17 years.
After a long season, this might be Djokovic’s best shot at overtaking Margaret Court and make history with 25 Grand Slam titles. Despite being out at 11/1, the four-time champion gets the nod to win the US Open in 2026.
