It also is the future home of the Chicago Sky of the WNBA.The arena was announced in May 2013, with construction planned to begin in 2014, and use expected to begin with the 2016 - 17 season. The start of construction was delayed to November 2015, with completion now expected for the 2017 - 18 season. Although DePaul had been seeking a new home arena — it has used Allstate Arena in suburban Rosemont since 1980 — it rejected a November 2012 ten-year offer to play rent free at the United Center. Instead, DePaul planned to use Allstate Arena on a recurring one-year basis until it had a new home. On November 16, 2016, DePaul and the Metropolitan Pier and Exposition Authority announced that the new event center at McCormick Square would be called Wintrust Arena. The announcement came after the signing of a letter of intent that contemplated a definitive 15-year sponsorship agreement between DePaul and Wintrust. In 2017 the Chicago Sky announced their move from Allstate to Wintrust.
