Story summary

Google announced a summer-2026 U.S. service that builds a single grocery cart from multiple retailers.
Bain says nearly half of U.S. shoppers use AI agents, which create multi-vendor carts.
Grocers warn AI agents can fragment orders by cherry-picking low-margin items, eroding basket profits.
Retailers may offset fragmentation with discounts, faster delivery slots, or pickup incentives.
Private-label brands such as Costco’s Kirkland Signature offer items AI agents cannot match, supporting margins.

History

Historical Context

Amazon introduced its Marketplace in November 2000, letting third-party sellers list alongside its own goods; by 2008 those sellers supplied roughly 40 % of Amazon’s sales. The model inspired Google’s 2026 shopping cart, which mirrors Amazon’s open-seller approach. Facing similar margin pressure, grocers such as Costco and Walmart now offer exclusive items and delivery incentives to protect profitability.
