Iconic Chicago exchange operator CME Group Inc. will decide “shortly” whether to keep its headquarters in Illinois, where it has a disproportionate tax burden, its executive chairman said Thursday.

Terrence Duffy said other U.S. states are seeking to attract the parent of the Chicago Mercantile Exchange and the Chicago Board of Trade, adding he expects to have these states’ proposals in hand in two weeks.

“We are definitely working and seeking proposals actively from other states, and they’re seeking us,” Duffy said in an interview. “We’re going to have a decision that needs to be made.”
