State of Play

Revised Sep 18, 2026

The moment. Measurement stopped being a complaint and became a subtraction. ARF research across 13 major buyers found five have cut or dropped retail media investment over measurement problems, with two naming it the primary reason. It landed in the week GroupM put global retail media at $101 billion this year, 18% of digital advertising and 11% of all ad spend. Kroger Precision Marketing posted 24% profit growth in the second quarter, its best since 2021. Sam’s Club Connect launched tools that predict future purchases rather than retarget past ones, including churn-prevention segments and audiences likely to buy big-ticket items. Walmart is adding marketplace data, custom dashboards and a deeper Marty AI agent to Scintilla next year.

The tension. The category crossed 11% of all ad spend and lost buyers in the same week, over the one thing it has promised since it started: proof. And the newest placement carries a misreading nobody has priced. Research covered by The Drum found more than half of shoppers believe an ad placed inside an AI tool makes a brand more likely to be recommended by that tool. Shelf placement was always understood as paid. An ad inside an answer is being read as the answer’s judgment, which is a borrowed credibility the networks did not earn and cannot guarantee.

Who’s moving. The ARF, putting a number on buyer withdrawal. GroupM, sizing the category at $101 billion. Kroger, on 24% profit growth. Sam’s Club Connect, moving from retargeting to prediction. Walmart, deepening Scintilla and testing endcap screens carrying live inventory and pricing. Walgreens, rebuilding in-store retail media and fitting 1,200 stores with Looma displays from October. Grocery TV, finding 62% of shoppers bought a product after seeing an in-store ad and front-end screen acceptance up 23 points since 2023. Target, hiring former Hilton CMO Mark Weinstein to oversee Roundel and Target+. Taboola’s Connexity, quietly buying Howl’s creator affiliate business.

What the desk is watching. Whether the five buyers who pulled back come back on better measurement or on better prices, and who takes responsibility for the shopper who reads a paid placement in an AI answer as a recommendation.
