Prediction markets put the probability at 42%: Will Jannik Sinner win the 2026 Men's French Open. Currently, markets are divided (42% YES, 58% NO). ATPTour.com looks at the top Movers of the Week in the PIF ATP Rankings, as of Monday 13 April 2026.
Jannik Sinner has returned to the world No. 1 ranking, reclaiming the top spot from Carlos Alcaraz after winning the Rolex Monte-Carlo Masters on April 13, 2026. This victory marked a significant milestone, as Sinner became only the second man after Novak Djokovic in 2015 to win the season's first three ATP Masters 1000 events. The win on clay is particularly notable for his campaign, directly addressing a key goal set by his coaching team for the 2026 season. [ATP Tour, Mon 13]
The Monte-Carlo final was the first clay-court meeting between Sinner and Alcaraz since the 2025 French Open final, where Alcaraz saved three match points to defeat Sinner in a fifth-set tiebreaker. That recent history at Roland-Garros is a critical factor in the current narrative, underscoring the high-stakes rivalry as the tour builds toward the major clay events. Sinner’s coaching team emphasized that winning a major clay title was a primary objective for this year, framing his current form as a direct build-up to the French Open. [Greenwich Time, Mon 13]
Attention now turns to the remaining clay-court Masters events, the Madrid Open and the Italian Open, which are the only two Masters 1000 titles Sinner has yet to win. His performance in these tournaments will be closely watched as the final indicators of form ahead of the season's second Grand Slam. The path for Jannik Sinner at the men's French Open appears to hinge on translating his dominant early-season hard-court and newfound clay success into a breakthrough at Roland-Garros, where he came agonizingly close in 2025.
