A leaked Adweek-reviewed file details how The Trade Desk partners with 49 retailers worldwide to sell ad placements built on shopper data. The document reveals steep markups and inconsistent rules: Albertsons charges up to 45% of media costs, Best Buy limits custom audiences, Costco sets $100K minimums, and Walmart imposes fees capped at $3.50 CPMs plus measurement charges. Other retailers add restrictions around ad categories or approvals. The leak highlights both the value and complexity of retail media as brands chase audience targeting tied directly to transactions. Transparency remains a challenge, with costs and conditions varying widely by partner.

Retailers have built lucrative revenue streams from retail media networks (RMNs), leveraging on-site ad inventory and first-party transaction data. As the potential grows for consumers to shop through AI agents instead of retailer sites or apps, those data streams and ad surfaces are at risk.

Only 40% of US retail media networks (RMNs) offer self-service sales data, according to Q2 data from Mars United Commerce.

AI-fueled gains kept Google, Meta, and Amazon atop Q2’s ad market, but slowing engagement, murky ROI, and macro risks leave the triopoly’s future growth story more complex than the headlines suggest.

For advertisers, the increasing fragmentation within the search landscape can be quite frustrating and challenging. “But for consumers it feels like ease and convenience," said our analyst Sarah Marzano on a recent episode of "Behind the Numbers." "We're able to conduct product searches wherever we're spending time and go on a journey that's tailored to the mindset we're in."

Kroger has consolidated its retail media, consumer insights, and loyalty marketing capabilities under the Kroger Precision Marketing (KPM) brand.

The news: Amazon reported strong Q2 results for its advertising business, with advertising revenues reaching $15.6 billion—up a significant 23% YoY. Net sales increased 13% YoY to $167.7 billion, well above Q2 guidance that warned of “tariffs and trade policies” and “recessionary fears.” Our take: Moving forward, Amazon will need to innovate what it’s already offering by pioneering a retail media strategy that extends Amazon’s data and ad tech beyond its own storefront, AI-driven tools that simplify creative production and optimization at scale while prioritizing privacy, and more immersive and shoppable ad formats in its streaming offering.

The number of retail media networks (RMNs) worldwide offering competitive conquesting (the ability to target campaigns to competitors’ shoppers) has risen from 10 in Q2 2024 to 15 in Q2 2025, a 50% increase, according to data from Mars United Commerce.

The situation: Amazon and Google, once bound by a symbiotic relationship in which Amazon funneled ad dollars into Google Search and Google indexed Amazon’s pages, are now veering toward open conflict as generative AI (genAI) blurs the lines between ecommerce, advertising, and search. Both companies are determined to own the entire journey from discovery to checkout, and that ambition is unraveling what remains of their former détente. Our take: Amazon and Google are racing to define where and how consumers discover and buy products in the genAI era. If Amazon succeeds in walling off its marketplace data and steering shoppers to its own AI interfaces, the retail landscape could splinter into walled gardens where tech giants cooperate far less. That winner‑takes‑all dynamic might suit the victors, but it risks degrading the overall consumer experience with fewer choices and less transparent pricing. At the same time, it could lead brands and retailers into a margin‑sapping race to the bottom inside whichever closed ecosystem proves most dominant.

Ocado Ads has partnered with data collaboration platform Permutive to make its first-party purchase data available to select UK publishers.

In-store retail media has long been a mysterious black box for marketers—hard to measure and optimize. But thanks to first-party shopper data and AI-driven measurement tools, that’s changing. Marketers can now pinpoint how shoppers engage with in-store campaigns and tie those interactions directly to sales.

Last November, our analysts made some predictions about how the retail category would fare in 2025. Now that we’re halfway through the year, it’s time to check back in on what has (or hasn’t) happened. "We're seeing many of our predicted trends playing out, though not always in the ways we anticipated," said our analyst Suzy Davidkhanian on a recent episode of the "Behind the Numbers" podcast. "The retail landscape is evolving rapidly, with some developments accelerating faster than expected while others face unexpected headwinds."

Criteo is modernizing retail media by launching a global auction-based ad platform and integrating with Mirakl to enable self-serve advertising for over 100,000 third-party sellers. This dual move addresses two persistent challenges: outdated fixed-price ad systems used by most retailers, and untapped ad spend from marketplace sellers. The auction system gives advertisers more control and performance insights, while Mirakl opens up a scalable, automated path for small sellers. Criteo also brings standardized attribution and reporting across retail partners—fixing transparency gaps. These changes position Criteo as a full-spectrum solution for brands, retailers, and sellers looking to compete in a fast-evolving market.

Retail media search ad spending propelled retail media ad spending to its current size. Now, more retail media networks are closing in on search feature parity, and advertisers are looking for ways to approach the critical channel.

Retail media is not just for retailers anymore. US commerce media ad spending is projected to hit $118.4 billion by 2029, growing at a 15.3% compound annual growth rate (CAGR), per a May EMARKETER forecast.

The commerce media space is growing fast, and as it gets more crowded, it’s becoming harder to keep up with the retail media giants. But by teaming up, smaller players can more easily scale their networks to achieve the reach to stay competitive.

To help advertisers better assess the effectiveness of their campaigns, Sam’s Club Member Access Platform (MAP) has introduced Omni-Impact—a new AI-powered measurement solution.
