Our Take
Retail media is attracting agency M&A because margins are fat and Amazon/Walmart control the shelf—but these bolt-on buys don't solve the core problem: each platform changes its algorithms and ad products faster than any agency can retrain staff.
Why it matters
Commerce agencies are betting that buying expertise in Amazon and Walmart marketplaces will let them serve brands at scale. The pattern suggests retail media is maturing from a niche to a standard agency service line, just as client budgets shift toward first-party commerce channels.

Commerce teams: audit your Walmart marketplace specialists' turnover rate and algorithm-tracking process before accepting any integration with a newly acquired team—acquisition velocity often outpaces knowledge transfer.
Four retail-focused acquisitions in five months
Podean, a commerce agency focused on Amazon and Walmart marketplace selling, acquired Cartbloom in May. This was Podean's fourth acquisition this year, with two more planned before year-end (company-reported). In the same month, The EVOQ Group, a network of independent agencies, acquired Red View Ventures, an Amazon specialist. Harvest Group, a shopper marketing firm, acquired Cartograph in April, which specializes in Amazon and ecommerce platform marketing.
The deals cluster in a single vertical: agencies are consolidating expertise in platform-specific retail media operations. Podean CEO Travis Johnson confirmed the acquisition pipeline is active and intentional.
Retail media margins justify the acquisition price
Amazon and Walmart advertising operate like owned media for these platforms. The commission structure and ad product roadmaps are controlled by the platform, not the agency. This creates two pressures: brands want single-vendor expertise because each platform's algorithm and ad product differ materially, and agencies can charge higher fees for proven category knowledge.
The acquirers are not betting on unique intellectual property. They are buying Rolodexes, staffing depth, and the credibility signal that comes with saying "our team knows Walmart's algorithm." That signal has measurable value in a category where performance is public (spend and sales are auditable) and client churn is rapid when results slip.
What these acquisitions don't solve: algorithm changes and product feature releases from Amazon or Walmart outpace the re-training cycle at most agencies. Buying a team of Walmart experts in May doesn't insulate that team from a significant ad product overhaul in July. The premium for "specialist" expertise is real, but the half-life is short.
Know what you're acquiring before the check clears
If you are the acquirer, map exactly which client relationships and which staff members are non-negotiable to the deal thesis. Retail media teams have high poach risk; competitors will contact your new hires within weeks. Document their current algorithm knowledge in writing (what do they know about Walmart's Q3 feed ranking changes?) and build retention agreements that extend past integration.
If you are a brand working with an acquired agency, ask directly whether your account team is staying and whether their platform-specific playbooks transfer to the acquiring parent or stay siloed. Many acquisitions create friction when the acquirer tries to "scale" the small team's methods across a larger, less specialized organization.
