Last week’s Amazon-Netflix partnership represents a convergence between commerce media and streaming TV that promises to blur the lines between brand-building and performance marketing while raising fundamental questions about which budgets, which teams, and which strategies will control advertising's future.

Programmatic has effectively become the defining mechanism for delivering ads. This benchmark guide unpacks how programmatic advertising is shaping spend in key channels.

The digital ad market is shifting fast. In court, Google admitted the “open web is already in rapid decline,” contradicting its public claims, as AI Overviews erode publisher traffic. The Trade Desk’s stock plunged 12% after Netflix’s Amazon DSP deal, with Morgan Stanley citing CTV headwinds and higher fees. Meanwhile, Reddit is positioning itself as a publisher ally, rolling out Reddit Pro to help offset traffic losses from search. Together, these moves underscore a fractured open web ecosystem: Google under pressure, The Trade Desk undercut by Amazon, and Reddit stepping up as publishers seek new discovery sources.

Tariffs and inflation are reshaping retail, pushing shoppers toward value and convenience. Off-price chains gained ground, while housing-linked retailers sought new growth paths in a slowing market.

"In the space of what amounts to less than two years, we've seen commerce media evolve from an emerging idea to an industry pillar," said our analyst Sarah Marzano during a recent EMARKETER webinar.

In-store retail media is Europe’s next big ad opportunity. But as retailers digitize stores, standardization and measurement challenges are dragging advertiser adoption.

US ad spend with financial media will reach over $600 millions this year, according to EMARKETER forecasts, but still represent a small fraction of the commerce media landscape. "This is a really nascent space. There aren't many players that make up this cohort of financial media networks (FMNs), and they represent a really diverse array of types of financial companies," said our analyst Sarah Marzano during a recent episode of "Behind the Numbers."

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.
