IllinoisOffice Cboe puts headquarters on the market ahead of move to Old Post Office August 2, 2019 Share on Facebook Share on Twitter Share on LinkedIn Share via email Cboe Global Markets, parent company of the Chicago Board Options Exchange, is putting 400 S. LaSalle Street up for sale. The building has long served as Cboe’s headquarters, but the move comes as the options exchange company looks to relocate next year, reportedly to the Old Post Office. The news came from Brian Schell—executive vice president, chief financial officer and treasurer at Cboe—during a conference call with analysts. According to Schell, Cboe expects to close the sale sometime between the second and third quarters of 2020. Cboe developed the 350,000-square-foot 400 S. LaSalle Street in the 1980s to serve as their corporate headquarters and the company now occupies approximately 300,000 square feet. However, the downsize to a rumored 175,000 square feet in the Old Post Office comes after the company’s workforce contracted in size after a 2016 merger with Kansas City-based Bats Global Markets.
