Walmart leads a fragmented global food and grocery retail market

A new Business Research Company report says the global food and grocery retail market remains highly fragmented, with Walmart holding the largest 2024 sales share at 0.4%. The report points to small-format urban stores, AI forecasting, micro-fulfillment and omnichannel retail as the main competitive battlegrounds through 2035.

Why it matters: - The food and grocery retail market is fighting for share in a low-concentration industry where scale, logistics and digital execution determine who wins. - The shift toward convenience-led shopping, faster delivery and online-offline integration is reshaping store formats and investment priorities. - The report frames the next phase of competition around supply chain efficiency, private labels, pricing and inventory technology.

What happened: - The Business Research Company published its Food And Grocery Retail Market Report 2026, covering market size, trends and global forecasts for 2026-2035. - Walmart led global sales in 2024 with a 0.4% market share, according to the report. - Costco followed at 0.3%, Kroger at 0.2%, and Carrefour, Tesco and Target each at 0.1%. - REWE Group held 0.04%, Lidl 0.03%, 7-ELEVEN 0.01% and Aeon 0.004%. - The top 10 players accounted for just 1% of total market revenue in 2024, underscoring how fragmented the market remains.

The details: - Major companies in the market include Walmart, Costco, Kroger, Carrefour, Tesco, Target, REWE, Lidl, 7-ELEVEN, Aeon, Leclerc, ASDA, Publix, Morrisons, Coles, Spar, Mercadona, Auchan, Wakefern, Sainsbury’s, HEB, Kaufland, Safeway, Meijer, Fred Meyer, Système U and Edeka. - Major raw material suppliers include Nestlé, Unilever, PepsiCo, Coca-Cola, Mondelez, Danone, General Mills, Kellogg, Kraft Heinz, Associated British Foods, ADM, Cargill, Bunge, Tyson, Hormel, JBS, Marfrig, Conagra, Saputo, Lactalis, FrieslandCampina, Barry Callebaut, Wilmar, Olam and Ingredion. - Major wholesalers and distributors include Sysco, Performance Food Group, US Foods, Gordon Food Service, McLane, Reyes Holdings, C&S Wholesale Grocers, SpartanNash, United Natural Foods, Core-Mark, Ben E. Keith, Shamrock Foods, Merchants Distributors, KeHE, Associated Wholesale Grocers, Coles Group Supply Chain, Woolworths Group Supply Division, Metro Inc. Wholesale Division and Carrefour Supply Chain Services. - Major end users include Walmart, Amazon, Kroger, Tesco, Aldi, Lidl, Target, Metro, Seven and I Holdings, Aeon, Woolworths, Coles, Sainsbury’s, Albertsons, Publix, Meijer, Big Bazaar, Reliance Retail, Lulu Group, SPAR, Edeka, Migros and Rewe. - The report says leading companies are building market share through diversified assortments, large store networks, supplier partnerships, omnichannel retail, private labels and digital grocery platforms. - The report also says demand for convenient shopping, rapid home delivery and integrated online-offline grocery ecosystems should favor strategic collaborations, supply chain optimization and regional expansion. - More information is available through the report sample request. - Access the full report is available through the company’s report page.

Between the lines: - The market’s tiny revenue shares suggest that even the biggest chains have room to gain, especially if they can translate scale into better pricing, fresher inventory and faster fulfillment. - Small-format urban grocery stores are emerging as a key response to changing consumer behavior. - Amazon launched amazon grocery in Chicago in October 2024, a 3,800-square-foot store with about 3,500 curated grocery and ready-to-eat products. - The compact format, curated selection and grab-and-go model are designed to speed up trips in dense urban areas. - The strategies highlighted in the report point to a technology race rather than a pure store-count race. - AI-powered demand forecasting, automated replenishment, micro-fulfillment centers and computer vision shelf monitoring are becoming core competitive tools.

What’s next: - The report expects omnichannel grocery, delivery speed and supply chain precision to remain central through 2035. - Retailers that expand freshness, local convenience and digital execution are likely to strengthen their positions. - The next competitive edge may come from better inventory control and smaller, faster store formats rather than from traditional expansion alone.

The bottom line: - The global food and grocery retail market is still highly fragmented, but the winners are increasingly defined by technology, logistics and convenience-led formats, not just size.
