Tennis Betting Specials For 2026: Carlos Alcaraz, Jannik Sinner & Novak Djokovic

The start of 2026 represents the beginning of a new tennis season. Only a few weeks after the 2025 ATP Finals, attention turns to the Australian Open and other outright tennis betting markets.

At William Hill, we have player-specific markets for the total number of Grand Slams they will win. You can wager on zero, 1, 1+, 2, 3, or 4 Grand Slams for each of Carlos Alcaraz, Jannik Sinner, and Novak Djokovic in 2026.

Carlos Alcaraz Specials

Winner of four of the last seven Slams, Alcaraz is deservedly world number one. You have to go back to 2021 for the last year that he didn’t win a Grand Slam – it’s no surprise he’s as short as 1/33 to win one or more Slams in 2026.

Betting Alcaraz not to win a Grand Slam at 9/2 seems like a wager on a major injury. He’s been notably durable throughout his career so far and he’s still in his early 20s. If he’s healthy for the full year, he’s going to win at least one Slam.

The chasm between Alcaraz, Sinner, and the rest of ATP Tour is massive. The pair have met in three consecutive Slam finals and are on a collision course for the Australian Open later this month. Anything other than an Alcaraz-Sinner final would be a major surprise.

We can pencil Alcaraz in for French Open success as he pursues a three-peat. It feels like two titles is the minimum with how he’s played over the last couple of years – the Spaniard is 2/1 to win two Slams in 2026.

Jannik Sinner Specials

Sinner’s record is arguably even better than Alcaraz’s. He’s reached five consecutive Slam finals, winning three, and has won the ATP Finals in 2024 and 2025. Since the start of 2024, a quarter-final appearance at Wimbledon is his worst Slam showing.

Over that period, the Italian has won four Slams and twice been named a runner-up. Alcaraz was the only man to beat Sinner in a Grand Slam in 2025.

The betting markets are even more favourable for Sinner than Alcaraz. He’s 1/66 to win at least one Grand Slam and out at 6/1 to win no Slams. Outrageously, winning all four Slams is only 10/1. No man has achieved that feat in the Open Era.

Sinner has been imperious on hard courts. He’s more than comfortable on the grass of Wimbledon. He won his final 16 completed matches of 2025 after losing the US Open final. At 9/2, three Slams is very much in play.

Novak Djokovic Specials

With only one Grand Slam final appearance in the last two years, which ended in a straight sets defeat to Alcaraz, a 38-year-old Djokovic isn’t capable of keeping up with the world’s top two.

Djokovic was eliminated at the semi-final stage of all four Slams last year. He pulled out of the ATP Finals with a shoulder issue and withdrew from the Adelaide International, citing the same problem. His involvement in the Australian Open is in doubt.

It was remarkable for Djokovic to win three Slams in 2023 when he was deep into his thirties. That was the last hurrah in his all-time great career, ushering in the Sinner-Alcaraz era.

The 3/10 price on Djokovic not to win a Grand Slam looks like great value.
