French Open 2026 Semi-Finals: Predictions, Order of Play & Best Bets
Roland-Garros will crown a first-time women’s Grand Slam champion. World No.1 Aryna Sabalenka — the last former major winner left in the draw — was stunned 3-6, 7-5, 6-0 by Diana Shnaider in the quarter-finals, so all four women in the last four are chasing a maiden title. Today’s semi-finals pit Mirra Andreeva against Marta Kostyuk in a rematch of this year’s Madrid final, while giant-killer Shnaider meets qualifier Maja Chwalinska — the world No.114 one win from the most improbable final in memory.
The men’s last four (Friday) is set too: Alexander Zverev, the only man left to have reached a Grand Slam final, faces Jakub Menšík, and Italy is guaranteed a finalist as Matteo Arnaldi takes on Flavio Cobolli. Below: the quarter-final results, the semi-final order of play, our best bets and the acca.

Quarter-Final Results: Sabalenka Stunned, Italy Makes History
The biggest shock of the fortnight: world No.1 Aryna Sabalenka, the last Grand Slam champion left in the women’s draw, was beaten by Diana Shnaider — so Roland-Garros is guaranteed a first-time women’s champion. Qualifier Maja Chwalinska continued her fairytale, while Flavio Cobolli and Matteo Arnaldi reached maiden major semi-finals to make it an all-Italian last-four clash.

Semi-Final Best Bets
Andreeva to beat Kostyuk
A rematch of this year’s Madrid final and their third meeting of 2026. Mirra Andreeva, the 19-year-old eighth seed, is the highest-ranked player left in the women’s draw and hasn’t dropped a set all fortnight. Marta Kostyuk has been superb — beating Swiatek and Svitolina — but Andreeva’s consistency edges it. Tip: Andreeva to win (around 8/13).
Shnaider to beat Chwalinska
Diana Shnaider arrives on a high after dismantling Sabalenka, and meets a qualifier ranked No.114 in Maja Chwalinska, whose dream run has been the story of the women’s event. Chwalinska has nothing to lose, but the big-hitting lefty Shnaider is rightly favourite to reach a first major final. Tip: Shnaider to win (around 1/3).
Zverev to beat Mensik (Friday)
The men’s standout. Alexander Zverev is the only man left to have contested a Grand Slam final, and his experience and clay pedigree should tell against the big-serving Jakub Menšík, who is into his first major semi-final. Tip: Zverev to win (around 2/5).
Semi-Final Acca
Two of today’s women’s picks plus Friday’s men’s leans, in one slip:
| Leg | Selection | Approx Odds |
| 1 | Mirra Andreeva to win | 8/13 |
| 2 | Diana Shnaider to win | 1/3 |
| 3 | Alexander Zverev to win | 2/5 |
| 4 | Flavio Cobolli to win | 5/6 |
Combined: around 9/2. Shnaider v Chwalinska is the safest leg on paper, but the all-Italian Arnaldi v Cobolli is a genuine coin-flip — treat the Cobolli leg as the risk. Build it with new-customer free bets via the Bet365 Bet £10 Get £30 welcome offer.
