Largest Grocery Chains in the US: 40,000 Supermarkets, Top 10 Hold About 60%

There are roughly 40,000 US supermarkets as of the 2023 Census Economic Census for NAICS 445110 (Supermarkets and Other Grocery Stores, Except Convenience Stores). That count excludes c-stores, dollar stores, warehouse clubs, and general-merchandise retailers with a grocery section. Counting all food-retail formats together pushes the number well above 100,000, but for vendors selling into supermarket operators, 40,000 is the working universe.

Progressive Grocer and Supermarket News rank grocery operators by self-reported annual revenue. That is the canonical industry view and it tracks deal flow and revenue concentration. This list ranks the same operators by US supermarket count, which is the unit that matters when you are selling software, refrigeration, or services into store managers. The views agree on who is at the top but disagree on the long tail. By revenue, Walmart and Kroger dominate. By store count, the top 10 own roughly 60 percent of the 40,000 US supermarkets, and the remaining 40 percent is regional, ethnic-specialty, and the franchised independent base that public statistics treat as one entity.

Walmart runs roughly 4,600 US Supercenters and Neighborhood Markets that sell full-line groceries. Kroger Co. operates around 2,720 supermarkets across Kroger, Ralphs, Fred Meyer, King Soopers, Smith's, Fry's, QFC, City Market, Dillons, and Mariano's. Albertsons Companies runs around 2,200 across Albertsons, Safeway, Vons, Jewel-Osco, Shaw's, ACME, Tom Thumb, Randalls, and Pavilions. Ahold Delhaize USA runs around 2,000 across Stop and Shop, Food Lion, Hannaford, Giant Food, and Giant/Martin's. The Kroger-Albertsons merger was blocked in December 2024.

More than pest control and less than the dollar-store sector. The 10 largest grocery operators by US supermarket count run roughly 24,000 stores out of 40,000, around 60 percent of the universe. The remaining 40 percent is regional banners (Wegmans, Meijer, WinCo, Winn-Dixie, Giant Eagle), ethnic-specialty chains, and the long tail of franchised independents under IGA (around 1,100) and Piggly Wiggly (around 500). Those franchised independents operate as roughly 1,600 separate owner-operators even though they share two brand banners.

Yes. The dataset is filterable by state, metro, ZIP, banner, parent company, and store format (full-line supermarket, limited-assortment discount, natural and organic, hispanic or asian specialty, military commissary, franchised independent). California, New York, and Texas together hold around 27 percent of US food-retail locations, so most vendors start with those three plus their named target metros.

Orbital refreshes the location graph against the universe of US small and mid-market businesses on a rolling monthly schedule. The June 2026 snapshot is the one quoted on this page. Progressive Grocer publishes annually and lags by 6 to 12 months. The Census Economic Census refreshes every five years (2017, 2022). Counts on this page move when stores open, close, or change hands, and the 2024 blocked merger plus the 2025 wave of Save A Lot store closures means the chain table is moving more than it used to.

Three cases. First, if you only sell to the chain HQ procurement team at Walmart Bentonville or Kroger Cincinnati, you need two phone numbers, not 40,000 records. Second, if you sell to grocery shoppers directly, you want consumer panel data, not B2B operator contacts. Third, if your sales motion only fires above 250,000 dollars in annual contract value, the long tail of single-store independents and franchised IGA operators will not fit your unit economics. Save your budget and call us when an enterprise-only motion stalls.

Both, depending on whose statistics you read. IGA and Piggly Wiggly are franchised brand banners that license the name to roughly 1,100 and 500 independent owner-operators respectively. Public statistics often roll them up as a single chain entry because the banner is unified. The buying contracts are not. Each store is a separately owned LLC with its own equipment budget, its own software stack, and its own owner-operator on the title. For vendors selling into grocery, IGA and Piggly Wiggly are roughly 1,600 long-tail accounts wearing two coats.
