Retail Media Monetization

Retail media monetization is how a retailer turns its site traffic, shopper data, and store footprint into advertising revenue. It sells sponsored product placements, display ads, offsite audiences, and data services to the brands and marketplace sellers whose products it stocks.

How retailers monetize retail media

In retail media monetization (also spelled monetisation outside the US), the retailer is the publisher and its retail media network is the ad business. Revenue falls into four groups:

  • Sponsored products: listings in the retailer's own search results and category pages, sold through auctions (see auction-based pricing).
  • Onsite display and video: banner and rich media placements priced on CPM or share of voice.
  • Offsite: the retailer's audiences applied to third-party inventory, covered in onsite vs offsite advertising.
  • Data and services: shopper insights, closed-loop attribution reporting, and campaign support.

The raw material is traffic plus first-party data. The buyers are the retailer's suppliers and, where it runs a marketplace, third-party sellers. Walmart opens formats such as Brand Shop to eligible suppliers and Marketplace brand owners, and Amazon sells advertising to sellers, vendors, publishers, and authors.

Why retail media margins are so high

Onsite, the retailer sells space on a digital shelf it already owns, in front of traffic it already has, so an extra sponsored slot should cost little to serve. BCG estimated in 2022 that onsite retail media would earn margins of 70% to 90%, and offsite 20% to 40% after media costs and agency fees, because offsite means buying someone else's inventory.

Company results show the scale. Walmart's global advertising business, including VIZIO, grew 46% to nearly $6.4 billion in the fiscal year that ended January 31, 2026. Amazon's worldwide ad revenue passed $68 billion in 2025, Marketing Dive reported in February 2026, still driven mainly by sponsored product listings. Neither company's results report an advertising margin, so the margin ranges above remain estimates.

Three retail media network models

How a retailer monetizes depends on what kind of retailer it is:

  • Marketplace-led networks such as Amazon earn most of their ad revenue from sponsored listings on the marketplace itself, bought by vendors and third-party sellers alike. See marketplace advertising.
  • Delivery platforms such as Instacart sell ads on their own marketplace and syndicate them to partner grocers' sites and in-store smart carts. See the Instacart RMN profile.
  • Omnichannel retailers pair store and loyalty data with digital inventory. Kroger says its purchase data covers more than 62 million households (accessed September 2026). See the Kroger RMN profile.

The model shapes where the money comes from. A Forrester survey published in January 2025 found that 36% of US retail media spend comes from brands' trade marketing budgets and 26% from shopper marketing budgets. Forrester analyst Nikhil Lai told Digiday that "shopper and trade dollars have strings attached". BCG estimated in 2022 that 30% to 40% of the market would be reallocated trade money, and called a retail media offering a defensive strategy for holding onto trade dollars.

Self-serve vs managed service: how networks sell

Networks sell the same inventory in two ways. With self-serve, brands and sellers run campaigns in the retailer's console and bid in its auctions, which lets many advertisers bid for the same placements, the demand that yield optimization works with. With managed service, the network's team plans and runs campaigns for the advertiser. Large networks often offer both; Amazon's DSP, for example, comes in self-service and managed options.

Behind either model sits a platform decision: build the ad technology or license it. Vendors such as Criteo offer retailers a self-serve platform plus access to brand and agency demand. BCG lists the core components of the stack: user interface, data management, ID resolution, audience building, order management, ad serving, measurement, and billing.

Target's Roundel shows the whole model at work. Target said in June 2026 that Roundel generates more than $2 billion of value and aims to double that value from 2025 to 2030. It sells through Roundel Media Studio with self-service and managed-service models, and in 2025 more than 30% of partner media spend ran outside Target's owned platforms. Our Target Roundel guide covers how to buy it.

Why it matters for brands and sellers

A network's revenue model shapes what it sells you. Keep the margin gap between onsite and offsite in mind when a network bundles offsite audiences and data products with sponsored search. Budgets tied to trade agreements come with conditions, while self-serve access puts bids and keywords in the brand's own hands. IAB and PwC note that commerce media growth slowed in 2025 partly because brands are challenging retailers to prove the value of incremental spend, and that brands must navigate multiple retailer ecosystems, disparate buying systems, and fragmented workflows.

So judge each network on its self-serve access, SKU-level reporting, and incremental results before moving budget, and compare them across networks. Our networks hub and retail media database put them side by side.

Frequently asked questions

How do retail media networks make money?

They sell ads on inventory they own, such as auction-priced sponsored products and onsite display, extend their audiences to third-party sites, and sell data, insights, and campaign services. Suppliers and marketplace sellers are the buyers, and larger networks sell both self-serve and through managed service.

Why is retail media so profitable for retailers?

The retailer sells space and an audience it already owns. BCG estimated in 2022 that onsite retail media would earn margins of 70% to 90% and offsite 20% to 40% after media costs. Walmart's and Amazon's results do not report an advertising margin, so treat these as estimates.

How big is retail media revenue?

IAB and PwC put US commerce media ad revenue, which includes some sellers beyond retail, at $63.4 billion in 2025. Amazon's worldwide ad revenue passed $68 billion in 2025, and Walmart's global advertising business, including VIZIO, reached nearly $6.4 billion in fiscal 2026. These scopes differ, so the figures cannot be added.

Should a retailer build its own retail media platform or use a partner?

Large networks such as Amazon run their own ad platforms. Smaller retailers can license ad technology that comes with a self-serve console and access to brand demand. BCG advises niche networks to assess and select vendors for ad serving, order management, measurement, and billing.
