Traditional retailing is a low-margin business. Grocery margins run in the low single digits. Even the most efficient retailers rarely push above 5–8% EBITDA from their core operations. Retail media is quietly changing that arithmetic — and the implications are profound.
The Margin Gap Is Enormous
Retail media revenue carries margins of 50–90%. On-site advertising — where the retailer controls the inventory, the data, and the technology — generates margins in the 65–85% range. Off-site comes in lower at 20–40%, but still well above any physical retail category. A retailer doesn’t need to run a massive advertising business to materially change its financial profile. A relatively modest retail media operation, scaled over time, can add 10–30% to EBITDA forecasts — turning a single-digit margin business into something structurally more profitable.
Amazon as the Extreme Case
Amazon’s advertising business generates operating margins estimated above 70%, on revenues approaching $47 billion. That advertising income effectively subsidises Amazon’s other operations while making the retail arm more competitive by keeping consumer prices low. The advertising business is now a core pillar of the Amazon investment case, not a footnote. Every major retailer is trying to replicate this dynamic at their own scale.
The European Opportunity Is Particularly Significant
European retailers are years behind US counterparts in retail media maturity. Tesco, Ahold Delhaize, and Carrefour are building advertising businesses from much lower bases — meaning the margin uplift opportunity is proportionally larger. Analysis suggests retail media could add 10–30% to EBITDA forecasts for leading European names by 2025E. For brands and agencies, this means the conversations about retail media investment with European retailer partners will only intensify. When your retailer is generating 65–85% margins on advertising revenue, they have very strong incentives to grow that revenue aggressively.
