Round 15 of the SMS Grup Efeler Ligi confirmed Ziraat Bankkart as the team to beat, while big results in Istanbul reshaped the chasing pack.
The league leaders showed no signs of slowing down, sweeping past Gebze Belediyespor in straight sets to stay seven points clear at the top. Behind them, the spotlight was firmly on Istanbul, where Galatasaray HDI Sigorta produced one of their strongest performances of the season, defeating Halkbank 3–0 at home. The win lifted Galatasaray to within a single point of second place, while Halkbank held onto their position despite the setback.
İstanbul Gençlik Spor Kulübü stayed close to the top three with a comfortable straight-sets win, as away victories for Akkuş Belediyespor and Gaziantep Gençlik Spor Kulübü highlighted the growing divide in the standings. Fenerbahçe Medicana were left frustrated after a 3–1 road loss to Spor Toto.
