We’re heading into the clay court season in tennis and looking forward to another exciting addition to the rivalry between Carlos Alcaraz and Jannik Sinner. Both are tipped to be in the French Open final, but who’ll clinch victory?
At prediction market Kalshi, both Sinner and Alcaraz hold very close numbers to emerge as the men’s singles champion, but it seems too early to call. As we write this, Alcaraz has pulled ahead by one point, but this could change following Sinner’s recent victories on clay. Here’s your total guide to making this pick on Kalshi.
The 2026 ATP French Open begins on the 24th May and we’re looking forward to epic rallies and intense competition across the whole competition, but particularly in the men’s singles draw. As it stands, many sites are predicting that the final will be another thrilling battle between Spain’s Carlos Alcaraz and Italy’s Jannik Sinner.
At the moment, Sinner and Alcaraz are very evenly matched on Kalshi, with an implied probability of French Open glory standing at 41% for Alcaraz and 40% for Sinner. Here’s how the two measure up in numbers:
Carlos Alcaraz is the defending French Open champion, having beaten Sinner in the 2025 final in dramatic fashion to secure his second French Open title. Both Alcaraz and Sinner served for the championship (Sinner in the fourth set and Alcaraz in the fifth), after Alcaraz came back from two sets down.
Sinner has only reached the French Open final once, in his match against Alcaraz. Following this, he went on to defeat Alcaraz in the next Grand Slam final at Wimbledon just a few weeks later. He has won the Australian and US Open and is only missing the French to complete the career Grand Slam.
The main men’s singles draw will feature 128 players divided into eight sections according to seeding. Novak Djokovic has won the French Open twice and should never be discounted as a possible finalist. Alexander Zverev is also a potential winner, having reached the final in 2024, where he lost in five sets to Alcaraz.
The French Open is famously the only tennis Grand Slam played on clay, which gives baked earth specialists a distinct advantage. Traditionally, Spain and Italy have more clay courts, so players who have trained in these countries tend to be more comfortable on this surface.
In the head-to-head record between these two, Alcaraz holds a very slight advantage, but there’s still time in the busy tennis schedule for this to shift.
Since this market opened, Alcaraz and Sinner have flipped back and forth as the main front-runners. As of this moment, Alcaraz has established a razor-thin edge.
Sinner has just clinched the biggest clay court title of his career so far, after defeating Alcaraz at the Monte Carlo Masters ATP 1000 event. This was a best-of-three-set match, so it’s important to take into account the possibilities for more dramatic twists and turns over the five-set format at the French Open.
This victory allowed Sinner to reclaim the world number one spot, which could provide extra motivation to underline his world leader status with a statement tournament final.
You can never count out upsets at Grand Slams, but they happen less frequently at the French Open. Weather conditions can impact ball speed and bounce on the clay, but the pros like Alcaraz and Sinner should be well prepared for any difficulties.
Alcaraz won the French Open back-to-back in 2024 and 2025, with both finals going to five sets. We’re expecting a Sinner versus Alcaraz final again, but it will be important to assess how each player’s progression through the rounds may impact this possibility. Heavy five-set matches along the way, late finishes, and matches played in challenging conditions, such as hot weather, could mean one player goes into the final more fatigued.
