Mars, the US-based snacking and confectionery giant, has announced a $100 million investment to expand its global headquarters in Chicago, creating 602 new jobs.
The project involves opening two new office hubs to house the company’s North America region and global functions. Mars will establish a regional office in the Fulton Market district and a new global home for its Accelerator Division in the former Kellanova headquarters in River North. According to the company, the new sites will provide capacity for more than 1,000 associates, adding to its existing workforce of 4,000 employees in the Chicago area.
The expansion follows the $36 billion acquisition of Kellanova by Mars that completed in December 2025, which added brands such as Pringles and Pop-Tarts to its portfolio. It also builds on a previous $42 million investment in a research and development facility on its Goose Island campus.
Andrew Clarke, global president of Mars Snacking, commented: “Chicago has long been a hub for our business, and now it is our official home for our North America region and our Accelerator Division — firmly establishing our legacy and our future together”.
According to sources, the state of Illinois is providing approximately $42.8 million in tax incentives through the EDGE programme to support the investment.
