The Open de Caen celebrates its 20th edition from December 13 to 16, 2026, at the Palais des Sports Caen-la-Mer, bringing together former champions and breakout international stars for its milestone event. Tournament organizers unveiled a star-studded lineup blending returning fan favorites with fresh contenders, aiming for a mix of competitive grit.
Valentin Vacherot and Casper Ruud Lead the Men’s Draw
Monaco’s Valentin Vacherot anchors the tournament’s headline acts following a stellar stretch on the ATP Tour. Vacherot claimed an ATP 500 title in Basel on October 26, 2026, and reached world ranking No. 14 on October 5, 2026, building on his breakout Masters 1000 victory in Shanghai in October 2025. He nearly upset Novak Djokovic at the Paris-Bercy Masters 1000 on November 3, 2026. General manager Arnaud Guimard praised the Monegasque player’s relentless style, noting that he has been in exceptional form over the past two seasons.
Joining Vacherot is Norway’s Casper Ruud, a former world No. 2 who reached the finals at Roland-Garros twice and the US Open once. Ruud holds 14 singles titles, predominantly on clay, and remains a fixture near the top of the men’s game. Guimard described the Norwegian as a versatile, technically complete competitor who brings established global pedigree to the Caen tournament. Ruud advanced at Bercy on November 3, 2026, defeating Spanish newcomer Rafael Jodar 6-3, 6-4.
Ugo Humbert and Holger Rune Return to Caen
The tournament also welcomes back two past winners who left lasting impressions on local crowds. France’s Ugo Humbert returns after capturing the 2024 Open de Caen title by defeating Cameron Norrie 6-1, 6-4, when Humbert stood at No. 14 in the world. Humbert also reached the 2023 final, losing a nearly three-hour battle against Alex De Minaur. He currently sits at No. 38 in the rankings.
Holger Rune rounds out the notable returnees. Rune holds the distinction of being the final champion crowned at the Zénith venue in 2022, where he defeated Roberto Bautista Agut 6-0, 6-4 before the Open de Caen transitioned across the street to the Palais des Sports. After missing nearly a year following an Achilles tendon rupture in October 2025, Rune returned to competition in September 2026 and reached the quarterfinals in Basel on October 30, where he fell in three sets to Vacherot.
Maja Chwalinska and Donna Vekic Complete the Field
On the women’s side, Poland’s Maja Chwalinska and Croatia’s Donna Vekic will compete at the Palais des Sports Caen-la-Mer during the four-day winter event. Organizers structured the player selection around a double philosophy: inviting active competitors who shaped previous editions and introducing fresh international faces to the Caen audience. Tournament management emphasized that selection prioritized competitive spirit and fighting qualities above simple rankings.
Palais des Sports Caen-la-Mer Hosts the Milestone Tournament
The tournament runs from December 13 to 16, 2026, at the Palais des Sports Caen-la-Mer. With matches scheduled across four days in mid-December, the event serves as a high-profile end-of-year tournament featuring Grand Slam finalists, Masters 1000 winners, and returning champions.
