Few meals are more American than a good old-fashioned sandwich—and National Sandwich Day is tomorrow (11/3)—which serves up a prime opportunity to take a look at the Quick Serve Restaurant (QSR) Sandwich subcategory, where 125 brands are buying sponsorship or media, averaging six sponsorship deals per brand.

Jersey Mike’s Subs leads the list by sponsorship volume with 135 deals. The NJ-based franchise has partnered with many prominent rights holders, including the NHL, the New York Yankees, and even Danny DeVito. In second place with 92 partnerships is Subway, the world’s largest sandwich chain with more than 44K locations in over 100 countries worldwide. The franchise—which partners with the NFL, the Toronto Raptors, and the UK’s Guild Esports—recently inked a deal with the Brazilian Olympic Committee ahead of the 2024 Summer Olympics in Paris. With 60 sponsorships, third-place Jimmy John’s of Champagne, Illinois, focuses its endorsement efforts on college sports, including rights holders like the Baylor Bears, Illinois Fighting Illini, and the Myrtle Beach Bowl.

Nearly 30% of sandwich deals have a social media component, with TikTok accounting for almost 60% of all branded post engagement in the subcategory. Collectively, these brands generated 2.6M in total engagement across 4.2K posts in the last year—the top three of which belong to Subway, which dominates QSR sandwich brands with engagement of 1.7M.
