Mars is sweetening its Chicago presence in a big way, with plans to add about 600 jobs and invest $100 million in its local operations, according to reporting published Wednesday, March 25, 2026. The move is one of the largest single local commitments from a snack-maker in recent months and will significantly expand Mars' footprint in the city. Local officials are already framing the deal as a meaningful boost for the region’s food-and-beverage economy.
As reported by Crain's Chicago Business, the plan calls for roughly 600 new positions and about $100 million in capital spending at the company’s Chicago operation. Specifics in the initial report were limited, and company representatives have not yet laid out a public hiring timeline.
Mars' Chicago footprint
Mars already runs a major research-and-development campus on Goose Island and opened a $42 million snacking R&D hub there in 2024, part of a broader push into local innovation, according to Mars. The company has described that hub as a core engine for new product development for brands such as M&M’s and SNICKERS. With that base already in place, Mars has a ready-made platform to scale up operations in Chicago.
Deal background and office plans
The expansion comes as Mars absorbs Kellanova, the Chicago-based snack spinoff of Kellogg, and has reportedly been touring large blocks of Fulton Market office space while rethinking its local footprint, according to The Real Deal. Industry watchers note that acquisitions on this scale often lead to hiring and targeted investment in the cities where work is centralized. Mars has not yet confirmed a single site for the new roles.
What it could mean for the local economy
Chicago has been pulling in corporate facility projects at a steady clip in recent years, with World Business Chicago reporting that the region ranked No. 1 for corporate relocation and site selection in 2025. That track record helps explain why a company like Mars is choosing to deepen its roots here. According to World Business Chicago, the metro area recorded thousands of qualifying projects last year, a volume that economic-development leaders hope will translate into durable employment growth. Local workforce groups are expected to track Mars’s hiring plans closely for chances to align training and placement programs with the new roles.
More detail on site selection and hiring timelines is expected in the coming weeks as Mars and city officials work through the remaining steps. For now, the announcement adds to a run of corporate investments that boosters point to as fresh evidence that the Chicago region remains prime territory for food and manufacturing employers.
