Amazon’s Prime Big Deal Days failed to spark early holiday shopping, with only 23% of consumers buying holiday items and just 7% picking up Halloween goods, according to a Numerator survey. Most shoppers used the event for everyday essentials, apparel, and beauty products rather than seasonal purchases. Despite 59% planning future holiday buys on Amazon, many were cautious due to inflation and economic concerns. With weaker engagement and no sales statement from Amazon, this year’s event likely underperformed expectations, highlighting a shift toward more deliberate, budget-conscious consumer behavior ahead of the holidays.

AppLovin’s launch of Axon marks its transformation from mobile gaming to full-scale AI ad platform — and one of ad tech’s boldest pivots yet. The new Axon Ads Manager promises real-time AI bidding, Shopify integrations, and transparent attribution as the company positions itself as a performance-driven alternative to Meta and Google. The rollout comes as the SEC investigates AppLovin’s data practices, spotlighting the tension between AI-powered innovation and compliance. Marketers see opportunity — regulators see risk.

The growth of commerce media investments promises to connect brands with customers for longer stretches of the customer journey, especially when shoppers are close to purchasing. Though much of this extended digital journey leaves out the physical store, this strategy is changing.

In five years, Instacart’s retail media network (RMN) has transformed from a simple performance engine into a full-funnel, end-to-end marketing ecosystem.

For years, the commerce media conversation has centered around one theme: Measurement. But that may be changing. “We are finally moving past just talking about measurement,” said Collin Colburn, vice president, commerce and retail media at the Interactive Advertising Bureau (IAB). “It’s a horse that’s been beaten over the head a little bit too many times.”

Kroger Precision Marketing (KPM) has introduced a new suite of off-site capabilities, aiming to help small- to mid-sized brands navigate the complexities of programmatic channels.

In-store retail media has the “reach, quality, rent, safety, and cultural relevance that marketers traditionally want,” said Andrew Lipsman, founder and chief analyst, media, ads, and commerce at Colosseum Strategy, during IAB’s Connected Commerce Summit.

Retail media has rapidly evolved from a nascent idea into a core pillar of digital advertising. “If retail media was a baby, it would be like crawling or maybe walking… you still need to get the fundamentals right,” said Arthur Sylvestre, vice president, digital commerce at Danone North America at EMARKETER’s Future of Digital Summit event.

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.
