Carlos Alcaraz is the betting favorite for the 2026 Rolex Monte-Carlo Masters, carrying an implied title probability of 49% after another clean start to his title defense. Jannik Sinner is close behind at 45.5%, setting up a narrow race at the top of the Monte Carlo tennis 2026 market as the tournament moves into the round of 16.
Alcaraz backed up that status by dispatching Sebastian Baez in the round of 32, while Sinner rolled past Ugo Humbert 6-3, 6-0. The draw also delivered shocks that reshaped the field, with Valentin Vacherot beating Lorenzo Musetti and Zizou Bergs ousting Andrey Rublev, reminders that this ATP Masters 1000 event can turn quickly once play starts to settle.
What gives Alcaraz the edge is not only the number beside his name. He has a favorable top-half draw and could face Alexander Zverev in the semifinals, a route that looks manageable compared with the problems waiting elsewhere in the bracket. Sinner, by contrast, was set for round-of-16 tests against Tomas Martin Etcheverry and Tomas Machac, a stretch that offers less room for error even after his one-sided win over Humbert.

The shape of the market also reflects the players’ wider reputations on clay. Alcaraz arrives with superior clay pedigree and multiple deep French Open runs, while Sinner is still trading on his push toward world No. 1 and the kind of explosive hardcourt momentum that has made him a threat in any setting. That contrast is part of why the field feels so finely balanced, even with Alcaraz holding the shortest number.

Novak Djokovic’s withdrawal because of a shoulder issue removed one of the sport’s biggest names from the conversation and changed the texture of the draw. It did not make the path easy for either front-runner, but it did leave the tournament leaning even more heavily on the Alcaraz-Sinner duel that now defines the market. For a field this deep, the favorite has been named; the hard part begins now.
