77th İstanbul Challenger TED Open

From September 1–7, 2025, the historic courts of Tenis Eskrim Dağcılık (TED) Club in İstanbul will once again host one of the ATP Challenger Tour’s most storied events: the 77th İstanbul Challenger TED Open.

First played in 1946, the İstanbul Challenger holds the distinction of being Türkiye’s longest-running international sports event, staged without interruption for nearly eight decades. As part of the ATP Challenger Tour, the tournament will welcome around 50 players ranked inside the world’s top 200, bringing elite competition to the heart of İstanbul.

More than just a tennis event, the İstanbul Challenger is a living tradition—an arena where Turkish players have gained international exposure and global stars have made crucial stops on their careers. With its mix of competitive tennis, rich history, and İstanbul’s vibrant cultural backdrop, the 2025 edition promises to be one of the highlights of the season.
