Madrid Open 2026 — Model Preview & Predictions
Carlos Alcaraz is out with a wrist injury for a second consecutive Madrid, which changes everything. With Alcaraz absent, Jannik Sinner enters as the overwhelming favourite — and the model agrees. Sinner's clay ELO rating is the strongest in the field and his surface-specific win probability against any likely finalist is above 65%.
The draw
The top half is brutal. Sinner shares his side with Ben Shelton, Arthur Fils, and Lorenzo Musetti — three players in the form of their lives after Munich and Barcelona. Shelton and Fils are on a collision course in the fourth round, with the winner likely meeting Musetti in the quarters before a semi against Sinner. That's a gauntlet.
The bottom half is far more open. Alexander Zverev — two-time Madrid champion and No. 2 seed — is the clear favourite from his side. Felix Auger-Aliassime, Daniil Medvedev, Alexander Bublik, and defending champion Casper Ruud are all in his half. Based on current clay ELO ratings, Zverev is the most likely finalist from this side of the draw.
Model ratings — court speed context
Madrid's court speed index sits at approximately 0.55 — one of the slower Masters 1000 surfaces on tour. Slower courts favour baseline grinders, extend rallies, and reduce the serve advantage. This hurts big servers like Medvedev and Bublik significantly. Players with strong return games and high rally tolerance — Sinner, Musetti, Fils — are systematically advantaged here according to the model.
Hot players entering Madrid
Shelton won Munich. Fils won Barcelona. Both are carrying momentum into a surface that doesn't obviously suit either of them — but form matters, and the model weights recent performance in its ELO calculations. Both are live outsiders.
Valentin Vacherot is worth watching at big odds. His clay ELO is underrated relative to his ranking, and he reached the Monte-Carlo semis last week.
Players to avoid backing
Medvedev's clay ELO is consistently one of the weakest among top-20 players. His win probability against any top-10 opponent on this surface is below 35% according to the model. Casper Ruud is defending champion but his form coming in is poor — the model doesn't support him as a value play at current odds.
Model predictions
Quarterfinals: Sinner over Fonseca, Musetti over Shelton, Auger-Aliassime over Bublik, Zverev over Dimitrov
Semifinals: Sinner over Musetti, Zverev over Auger-Aliassime
Final: Sinner over Zverev
Sinner's clay ELO gives him a win probability of approximately 68% in a hypothetical final against Zverev. The model is clear — barring injury or an extraordinary run from Fils or Shelton, this is Sinner's tournament to lose.
