Artificial intelligence is transforming how brands navigate media buying, with digital ad buyers using AI for processes like ad personalization, audience insights, and creative ideation. In a conversation with EMARKETER, Mike Hauptman, CEO of cross-DSP manager AdLib, discussed how AI is altering the media buying landscape. Marketers are operating in a landscape where AI is a necessity—but as challenges are expected to persist for years to come, those who thrive will be the ones who find a happy medium.

GumGum’s CMO Kerel Cooper says contextual advertising has shifted from an education hurdle to a growth engine. In an EMARKETER interview at Advertising Week New York, he described how AI now interprets full-page or frame-by-frame context, allowing brands to reach audiences based on meaning rather than identity. As cookies fade, contextual ads offer privacy-safe precision and brand safety at scale. Cooper calls this “mindset marketing”—targeting users in the right headspace, not just the right demo. With the open web regaining advertiser trust and AI powering deeper relevance, contextual targeting is emerging as the foundation of a healthier ad ecosystem.

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.

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.

The news: Despite the shift toward programmatic advertising, a study from the Association of National Advertisers (ANA) identified a lingering issue with the trend: The growth of wasted ad spending. The amount of wasted ad spend in programmatic advertising has risen 34% in two years, up to $26.8 billion from $20 billion in June 2023. Our take: The efficiency and growing relevance of programmatic comes with brand safety trade-offs, making transparency and stronger verification a prerequisite for sustained investment.

The Trade Desk will join the S&P 500 on July 18, a milestone that highlights the company’s growing importance in the ad tech space. TTD has recently introduced tools like Deal Desk and AI-powered video placements via Kokai and Rembrand, all while vocally criticizing Amazon’s bundling practices. Despite a 30% YTD decline in stock price, the company’s Q1 revenue rose 25%, and retention remained above 95%. With Ventura OS on the horizon and renewed leadership in place, TTD is positioning itself as a transparent, open-web alternative to Big Tech’s walled gardens—just as it prepares to enter a new phase of institutional visibility.

The news: Amazon will bring inventory from Roku to its demand-side platform (DSP), the two announced at Cannes Lions, starting in Q4 2025. Our take: Amazon’s Roku partnership is a well-timed announcement to convince advertisers to stick with their CTV ecosystems even amid tightening budgets.

Programmatic ad buying is undergoing a sea change: Microsoft’s DSP closure signals a smaller role for Big Tech in managing third-party ad inventory—so who will take its place?

The news: Quality control is a growing fear for advertisers as an Adweek investigation found ads from major brands appeared near offensive and inappropriate content. Ads from brands like Amazon and Verizon were found near sexual or racially offensive content on the Android short-form video app XShorts. Our take: Advertisers are increasingly faced with a digital landscape where programmatic ad buying lacks the quality control required to keep up with rapid innovation and demand for ad space—prompting renewed calls for transparency, verification, and human oversight in automated systems.

Amazon’s retail media ad revenues will exceed $60 billion, per WARC: The change represents its steady growth despite broader economic setbacks.
