The parent of the Chicago Board Options Exchange plans to sell its South Loop headquarters, with a company spokeswoman saying Friday the listing is expected in the “coming weeks.”

The company has received “multiple indications of interest from potential buyers,” the spokeswoman said.

The announcement, which came during a conference call with analysts, comes on the heels of reports the options exchange company is eyeing a move to the Old Main Post Office, which is being redeveloped.

The “planned relocation is a result of a reduction of Cboe’s employee work space requirements in Chicago ... and is projected to be completed in the second or third quarter of 2020,” Brian Schell, the company’s executive vice and chief officer, said during the conference call.

Crain’s Chicago Business reported July 31 that parent company Cboe Global Markets is negotiating a deal for about 175,000 feet in the post office building. The options exchange has occupied about 350,000 square feet at 400 S. La Salle St. since 1984.

A spokeswoman Friday refused to confirm plans to move to the post office building.

“As we’ve stated previously, Cboe is evaluating its current real needs, and we are looking at various options in the area as part of our ongoing plan to meet the needs of current and future workforce, as well as our customers and trading floor company,” the spokeswoman said.
