Walmart is bringing selected products from independent marketplace sellers into the storage areas of its US stores. Instead of shipping goods from distant fulfilment centres first, participating providers can make items available for local pickup and fast delivery. The test shows how closely delivery speed, product recommendation and retail media advertising will work together in future.
Why Walmart is bringing third-party goods into its stores
At the Piper Sandler investor conference on 16 September 2026, marketplace manager Manish Joneja described the model: Walmart uses regional demand and customer data to bring suitable products from selected sellers closer to potential buyers. The items initially end up in the storage area behind the sales floor, not regularly on the shop shelves. Via the online shop they can appear in the basket together with the weekly shop.
Adweek picked up the test in October. The decisive innovation lies in the delivery route: a marketplace item can arrive with a grocery order instead of travelling separately for several days. Walmart decides which products are stored in which store based on local demand. The pilot is therefore designed for specifically selected items.
Infrastructure for 30-minute shopping
Walmart has already created the prerequisites. In May the group reported that it offers deliveries in 30 minutes or less in 33 US markets. More than 100.000 items are suitable for the fast assortment; already in the first quarter 2026 millions of such deliveries took place in over 19.000 US postcode areas.
For third-party providers this is a considerable lever. In the investor conference Joneja explained that the marketplace business grew by more than 50 percent in each of the first two quarters. Around half of marketplace sales now run through Walmart Fulfillment Services. According to him, goods stored there achieve a conversion rate more than 50 percent higher and lower handling costs than comparable offers outside the system.
So it is about a new combination: suitable stock in the right place, short delivery times and a platform that understands customers better from data.
Retail media becomes a question of delivery capability
The model also changes advertising planning. If a customer can receive a product today, the delivery promise itself becomes an argument in the paid search result. For sellers, besides CPC and ROAS, regional demand, storage position and actual availability for express orders will increasingly count.
Walmart has in any case expanded its advertising infrastructure in recent months: Walmart Connect is expanding CTV, offsite and social advertising. Added to this are Walmart purchase data for CTV campaigns via Vibe and AI-based shopping agents with approval rules. The in-store warehouse is the physical counterpart to these digital offers.
What retailers can learn from this for Germany
The concrete pilot runs in the USA, where Walmart uses its huge store network. The principle is also interesting for German retailers: regionally available stock can make the basket more attractive – and local delivery capability can improve the effect of a campaign.
For platforms with a store network, products with spontaneous demand are particularly suitable: accessories, pet supplies, household items or last-minute gift ideas. The key is to think assortment, product data, local stock levels and ad management together. The retail media expansion by DoorDash and Instacart shows a different route to the same goal: bringing advertising closer to the actual purchase.
With this, Walmart turns its greatest traditional strength, its local stores, into a competitive advantage for third-party sellers. The test is a preview of a retail landscape in which the question "Can I get it today?" is increasingly answered already at the product search stage.
