The Sinan Erdem Dome, among the largest indoor arenas in Europe, hosted the final of the 2010 FIBA World Championship, the 2012 IAAF World Indoor Championships, as well as the 2011–12 Euroleague and 2016–17 EuroLeague Final Fours. Prior to the completion of the Sinan Erdem Dome in 2010, Abdi İpekçi Arena was Istanbul's primary indoor arena, having hosted the finals of EuroBasket 2001. Several other indoor arenas, including the Beşiktaş Akatlar Arena, have also been inaugurated since 2000, serving as the home courts of Istanbul's sports clubs. The most recent of these is the 13,800-seat Ülker Sports Arena, which opened in 2012 as the home court of Fenerbahçe's basketball teams. Despite the construction boom, five bids for the Summer Olympics—in 2000, 2004, 2008, 2012, and 2020—and national bids for UEFA Euro 2012 and UEFA Euro 2016 have ended unsuccessfully.
