Key Players
Competitive Landscape
US competition centres on store density and delivery speed. Walmart grew US e-commerce 24% in the quarter to July 2026, Kroger pivoted from automated centres to store-based delivery with Instacart, DoorDash and Uber Eats as partners, and Amazon extended same-day perishables to more than 2,300 cities and towns. Instacart competes through retailer partnerships and AI ordering, and orders placed through the pilot assistant run above the standard order value. In India, Blinkit, Instamart and Zepto run 2,443, 1,171 and 1,139 dark stores respectively on the latest disclosures, with Zepto's June 2026 updated draft prospectus seeking a fresh issue of up to INR 8,010 crore.

Who leads the online grocery market?
Brick Meets Click data credit Walmart with close to 37% of American online grocery spend in early 2026, the biggest disclosed national position. Blinkit leads Indian quick commerce on orders and is the only one of the three main operators with positive adjusted EBITDA. No source ranks operators by global online grocery sales.
Which companies show the widest recent product coverage?
Instacart discloses orders, gross transaction value and adjusted EBITDA each quarter, Ocado Retail publishes basket and order growth, and Eternal reports Blinkit net order value and adjusted EBITDA.
What should buyers evaluate before approving a supplier?
Brands and retailers selecting a platform partner should compare average order value, fees per order, substitution and spoilage rates for fresh items, and the platform's delivery radius from store or dark store. Margin disclosures, such as Instamart's guidance for contribution margin between zero and minus 100 basis points, indicate how long promotional support may last.
How is competition expected to change through 2036?
Consolidation is likely around existing stores in the US and UK, with margin-led price discipline among Indian quick commerce operators. Ocado's technology partners have already closed sites, including Kroger and Sobeys centres that generated GBP 260 million of net closure receipts in the first half of 2026.
