Kroger's Ad Business Posts Its Strongest Profit Growth Since 2021
Kroger's retail media business delivered its strongest profit growth since 2021 in its latest quarter, reinforcing how high-margin advertising has become the engine of profitability for grocers operating on razor-thin core margins.
The numbers
Kroger's advertising business recorded its most significant profit growth since 2021, according to results reported by Digiday and Modern Retail around its Q2 2026 earnings. As the grocer's core same-store sales stayed roughly flat, its retail media arm stood out as a clear bright spot in the numbers.
The contrast tells the whole story of modern grocery economics: selling groceries is a low-margin grind, while selling ads against shopper data is enormously profitable. Retail media is increasingly where the money is actually made.
Why retail media is so valuable
Grocery is a notoriously thin-margin business, often operating on low single-digit profitability. Retail media flips that equation. Selling advertising against first-party purchase data carries margins that can dwarf the core business, which is why every major retailer is racing to build one.
The strategic asset is data. Retailers know exactly what shoppers buy, and that closed-loop measurement — connecting an ad to an actual purchase — is precisely what advertisers are desperate for as third-party cookies fade. Kroger's data is, in effect, a media product with grocery attached.
The bigger shift in retail
Kroger's results are a data point in a structural transformation. Retailers are becoming media owners, and advertising is moving from a nice-to-have side hustle to a core profit centre that can subsidise prices and fund growth elsewhere in the business.
The caution is over-monetisation. Cram too many ads into the shopping experience and retailers risk degrading it, eroding the very customer relationship that makes their data valuable. The best operators will balance ad revenue against experience with discipline, not squeeze every last impression.
What brands and retailers should take from it
For advertisers, retail media's closed-loop measurement is a genuine advantage, but scale and standards vary widely between networks. Push for transparency and incrementality rather than assuming every retail media dollar is working as hard as the retailer claims.
For retailers of any size, the lesson is that your first-party data may be your most valuable, highest-margin asset. Even smaller businesses can monetise audience and insight — the principle scales down from a grocery giant to a single strong customer relationship.
Quick FAQ
What did Kroger report?
Kroger's advertising business posted its strongest profit growth since 2021 in its Q2 2026 results, even as core same-store sales stayed roughly flat, per Digiday and Modern Retail.
Why is retail media so profitable?
Grocery runs on thin margins, but selling ads against first-party purchase data carries far higher margins and offers advertisers the closed-loop measurement they increasingly want.
What is the risk for retailers?
Over-monetising the shopping experience with too many ads can degrade it and erode the customer relationship that makes the underlying data valuable.
Kroger's results expose grocery's open secret: the groceries are the low-margin grind, and the ads are where the money is actually made. First-party purchase data is a media product with a supermarket attached. The discipline that separates winners is restraint — monetise the audience without degrading the experience that makes the data worth anything in the first place. — Daniel Nikolla, Founder of Merx Marketing
The takeaway: retail media is the highest-margin growth engine in grocery because first-party purchase data is a media product — but the winners monetise it without degrading the shopping experience that makes the data valuable.
What first-party data does your business sit on that could become its highest-margin asset — and are you using it, or letting it gather dust?
