CMO TLDR: WPP, Amazon & the Bot Buyers
The AI Ad Economy
Marketers Build a Cage Around the AI Agents They Just Hired
Brand and agency executives are racing to deploy AI agents in programmatic buying, then immediately fencing them in with spend caps, brand-voice gatekeepers, and data anonymization rules to prevent autonomous bots from torching a quarter of budget over a weekend. Bayer is throttling spend to protect testing with new data partners, while Kelly Scott Madison Media has built an internal agent it calls the librarian to police client brand voice before any other agent touches a campaign. The message from the Digiday Programmatic Marketing Summit is unambiguous; marketers want the productivity, not the hallucinations, and the IAB Tech Lab is moving to standardize controls before AI deepens an already opaque buying ecosystem.
Hershey Bets Agentic MMM Is Worth Owning, Not Outsourcing
Hershey spent a year building an in-house system of AI agents, partnering with Mutinex and Tracer.tech, that compresses media mix modeling from months to weeks and is now steering real budget decisions, including a lean into Reddit that the confectioner says moves more units per dollar than any other channel. Vinny Rinaldi, vp of media and marketing technology, says the shift toward relevance over reach has reshaped how Hershey thinks about its 72% digital, 28% traditional portfolio heading into upfronts. The strategic stake is clear; Rinaldi argues measurement intelligence is now a competitive moat brands should own outright rather than rent from agencies or platforms.
Duluth Trading Hands Bidding to the Bots, Keeps the Jokes for Humans
Duluth Trading Company has split the agentic AI question down the middle, letting its agency partner run automated bidding and creative iteration while keeping brand voice, humor, and overall ethos under human control. Director of marketing Ellie Uberto says the trust comes from the agency knowing the brand intimately, not from the technology itself, a distinction that reframes agentic adoption as a relationship question rather than a tooling one. For CMOs, the Duluth model offers a workable middle path between full automation and AI skepticism, preserving brand equity while still capturing efficiency gains.
Agencies & Platforms
WPP's First Female CEO Inherits a Stock Down 30% and a Ticking Clock
Cindy Rose is trying to pivot WPP toward an AI-driven future while cutting costs, ending internal rivalries, and destigmatizing risk-taking, all under the shadow of a stock that has lost roughly 30% of its value since she took the helm. The Cannes Lions festival next month will be her highest-profile stage to prove that holding companies can still command relevance as AI compresses creative and media workflows. The stakes extend beyond WPP; if the largest agency network cannot demonstrate AI fluency at the top, the entire holding-company model faces an existential repricing.
Buyers to Google, The Trade Desk and Meta: The Black Boxes Are Getting Worse
At Digiday's Programmatic Marketing Summit, brand and agency executives unloaded on the industry's most powerful platforms, with one buyer saying Google doesn't care that DV360 is terrible because Performance Max is quietly absorbing the entire ecosystem. Critics described PMax as unsold remnant inventory dressed up as premium, flagged geo-reporting changes that obscure where ads actually run, and accused The Trade Desk and Meta's Advantage+ of similar opacity. The frustration matters commercially; when buyers stop trusting the dominant DSPs, dollars start hunting for alternatives, and the IAB's push for server-side standards starts looking less optional.
CTV, Commerce, and Earnings
Amazon Turns Prime Video Ads Into a Shopping Funnel of One
Amazon Ads has launched Dynamic TV Creative on Prime Video, a capability that automatically personalizes interactive video ad elements, call-to-action, headline, and product imagery at impression time using Amazon's trillions of shopping and streaming signals across 90% of U.S. households. Hershey is an early adopter, with Amazon citing studies showing interactive video ads drive 6x higher brand search and 5x higher purchase rates versus standard streaming campaigns. The play tightens Amazon's grip on the full funnel inside CTV; advertisers upload one asset, and Amazon's authenticated graph does the rest, leaving rival streamers to explain why their reach data cannot match.
Ad Tech's Q1 Scorecard: AI Talk Is Loud, AI Revenue Is Still Quiet
Twelve publicly traded ad tech companies reported Q1 earnings over the past two weeks, with most posting revenue gains but three, including Teads (down 7% year over year) and Criteo (down 6%), flashing warning signs as analysts press executives on whether AI will erode platform stickiness. The Trade Desk beat with $689 million in revenue but saw its stock punished after a soft $750 million Q2 forecast and the departure of CSO Jed Jacobson to OpenAI, while CTV emerged as the single brightest growth segment across nearly every report. The takeaway for CMOs: AI is reshaping vendor narratives faster than vendor P&Ls, and the gap between agentic ambition and agentic revenue remains the sector's defining tension.

Retail Media Networks Are In Their 'Gangly Teenager' Phase. They're Trying to Grow Up.
Albertsons, Home Depot, DoorDash, and JPMorgan Chase will stage an upfront-style event in September called Ascendant, aiming to win brand budgets as U.S. retail media spend climbs 19% to $72 billion this year, per Emarketer. The challenge: Amazon already commands nearly 80% U.S. share, and WPP Media warns smaller networks face existential pressure unless they consolidate data or differentiate inventory.
Forget Dances. TikTok Wants People To Shop.
TikTok used its TikTok World event in New York to launch TikTok GO for in-feed travel booking, Branded Buzz for scaled creator collaboration, Search Hubs for sponsored brand pages, and a new Model Context Protocol that lets marketers connect external AI systems directly to the platform. Combined with creative tools powered by ByteDance's Dreamina Seedance 2.0 video model, the rollout cements TikTok's repositioning from entertainment app to end-to-end commerce engine, just as broadcasters fight for upfront dollars.
Heineken Pours 189% More Into Soccer Ahead of World Cup
Heineken USA is increasing soccer spend by 189% year over year, launching a 'Fans Have More Friends' brand platform, limited-edition soccer-themed packs in retailers like Publix, and watch parties in Los Angeles, Houston, Philadelphia, New York, Miami, and Dallas. The brewer is not an official 2026 FIFA World Cup sponsor but is betting that experiential and retail activation can capture the cultural moment more cheaply than the sponsorship tier.
Server-Side Implementations for AdTech
Server-side adoption has reached 30% to 40% of the top 1,000 websites globally, with publishers and advertisers routing data through their own infrastructure to sidestep browser restrictions, ad blockers, and degraded signal quality. The IAB Tech Lab's Trusted Server initiative is pushing standards for consent enforcement and auditability, positioning server-side architecture as the operating system for the post-cookie, AI-driven ad stack.
