Old Mission Capital is trading the Loop for Fulton Market, lining up a much larger office presence at one of Chicago’s most in-demand business addresses. The move gives the Chicago trading firm a new foothold in the neighborhood while its existing downtown lease remains in effect.
Per The Real Deal, Old Mission plans to sublease 70,000 square feet at 167 North Green Street from ArcBest, which holds a lease at the building through 2034. Old Mission currently occupies about 52,000 square feet at 1 North Dearborn Street and plans to sublease that space through August 2028, meaning the firm is adding a new address before its old commitment fully runs out.
Old Mission Is Leaving A Loop Lease Behind
Old Mission describes itself as a privately held quantitative market maker that uses proprietary technology and trading models across equities, bonds, currencies and derivatives. The firm’s Old Mission website says its platform has traded trillions of dollars in securities since the company began building it in 2008.
The relocation is the second time Old Mission has shifted its office setup since the pandemic. The firm previously signed a sublease at 1 North Dearborn in 2020, according to an earlier report from The Real Deal.
Fulton Market Offers A Different Office Pitch
At 167 Green, Old Mission will be moving into a 17-story office tower developed by Focus and Shapack Partners. The developer describes the building as offering more than 750,000 gross square feet, with a rooftop amenity suite, fitness facilities, lounge space, a terrace and a basketball court, according to Shapack Partners.
That amenity-heavy pitch is part of Fulton Market’s broader transformation from an industrial district into a corporate and lifestyle hub. Meanwhile, the Loop is still working through its own reset, including an office-to-apartment conversion at 65 East Wacker Place that Hoodline reported is set to create 252 residential units.
Old Mission’s move does not mean the Loop has lost every office tenant, or that Fulton Market has become a one-way escape hatch. But it does show how Chicago companies are continuing to reshuffle their footprints around newer buildings, stronger amenities and neighborhoods that can offer more than a traditional nine-to-five commute.
