# Retail Media's $60B Market Is Creating a Two-Tier System That Hurts Independent DTC Brands

*U.S. retail media ad spend has surpassed $60 billion, but independent DTC merchants on Shopify, WooCommerce, and BigCommerce face structural disadvantages versus large CPG advertisers — and rising CPCs, questionable attribution, and unequal platform access are prompting a rethink of channel strategy heading into Q4 2026.*

Retail media networks have become one of the dominant forces in U.S. digital advertising, but a growing number of independent merchants and their agencies are questioning whether the channel's celebrated returns hold up under rigorous scrutiny — and whether the market's structure fundamentally favors large consumer packaged goods brands over smaller DTC operators.

## The $60 Billion Figure Obscures Who Is Actually Spending

U.S. retail media ad spend has crossed the $60 billion mark, a figure widely cited by eMarketer in its 2025 and 2026 forecasts. Amazon Advertising alone is the dominant player: the company reported $56.2 billion in advertising revenue in 2024. Walmart Connect posted double-digit growth through the first half of 2025, and networks including Instacart, Kroger, and Target's Roundel all expanded self-serve advertiser tools over the same period.

But analysts and agency practitioners argue the aggregate figure masks a structural divide. The bulk of retail media spend flows from large CPG advertisers — companies like Procter & Gamble, Unilever, and Nestlé — that treat the channel as an evolution of traditional trade promotion. Money that previously went to slotting fees and co-op advertising is now being routed through Amazon's Demand-Side Platform and Walmart Connect's managed service tier. Those advertisers bring dedicated trade marketing budgets, managed-service account teams, and category-level data sharing agreements that self-serve merchants on Seller Central do not receive.

Access thresholds reinforce the gap. Amazon's managed-service DSP, according to the company's own publicly posted documentation, carries a minimum spend threshold cited at $35,000 per month for full-service access — a floor that immediately excludes the median Shopify seller. Target Roundel, per Target's publicly available vendor partnership documentation, remains largely a managed-service-only operation for most brand categories. The result, as the source analysis describes it, is "a two-tier market" in which large endemic advertisers access better data, better placements, and lower effective CPMs through preferred arrangements, while independent brands compete at auction against those better-resourced advertisers for the same sponsored placement real estate.

## ROI Scrutiny Intensifies as CPCs Rise and Attribution Is Questioned

Rising costs are compounding the access problem. Amazon's sponsored products cost-per-click rates have climbed substantially from 2022 levels, a trend documented in Jungle Scout's quarterly State of the Amazon Seller reports, which tracked average CPCs rising across major categories through 2024 and into 2025.

At the same time, retail media's signature selling point — closed-loop attribution — is under renewed challenge. In June 2025, the Interactive Advertising Bureau released an updated Retail Media Measurement Standards guidance document. The IAB's stated concern was that "inconsistent attribution windows and incrementality definitions make cross-network comparison unreliable for advertisers." The guidance calls on networks to disclose attribution windows, methodology for incrementality measurement, and definitions of what counts as a viewed or clicked ad. Adoption is voluntary, and not all networks have publicly committed to full compliance.

Performance marketing agency Tinuiti has published research on its website examining incrementality testing methodologies for Amazon Advertising. That body of published work finds that advertised ROAS and incremental ROAS can diverge significantly, particularly in mature categories with high organic search share — meaning brands that already rank organically for core keywords may be paying for sponsored placements that cannibalize clicks they would have received anyway.

## Not All Networks Are Equally Problematic for Independent Merchants

The merchant dissatisfaction is not evenly distributed across networks. Instacart Ads is frequently cited as a relative bright spot for independent brands in grocery and consumables, having invested in self-serve tooling with lower effective entry points. eBay has also drawn merchant interest after relaunching its promoted listings standard format with a tiered cost-per-sale model that only charges advertisers when a sale occurs — a structure that removes the CPC risk that makes Amazon sponsored products expensive to test for smaller sellers.

Walmart Connect occupies the most contested position. Walmart reported a 22% increase in U.S. e-commerce sales in its fiscal Q1 2026 earnings, released in May 2025, creating an advertising audience that independent merchants cannot ignore. However, the self-serve advertiser experience on Walmart Connect is described as less sophisticated than Amazon's interface, and Walmart's overall marketplace GMV remains a fraction of Amazon's, limiting reach for advertisers targeting broad consumer audiences.

## How Independent Merchants Are Rebalancing Their Channel Mix

The practical response from DTC operators and their agencies has been a partial rebalancing rather than a wholesale exit from retail media. Publicly documented moves include increasing investment in owned channels — specifically email and SMS, where Klaviyo's 2025 benchmark reports document open and click rates that retail media cannot replicate for repeat-purchase categories. Merchants are also using retail media budgets more surgically, focusing on new-customer acquisition keywords while pulling back on branded and defensive spend where incrementality is lowest.

Some operators are testing Google Shopping's Performance Max campaigns as a complement or partial substitute, though Google's removal of granular PMax reporting controls has generated its own debate about attribution transparency. Retail media management platform Pacvue, which integrates with Shopify and other platforms via API, has published documentation on its website describing incrementality experiment frameworks available within its platform — part of a broader agency and software ecosystem now treating incrementality testing as a standard practice rather than an advanced capability.

## What This Means for Your Business

For marketing teams at small and midsize e-commerce companies deciding Q4 budget allocation, the evidence points toward a disciplined, divided approach. Proven retail media placements where ROAS history is strong are worth maintaining, but the growing body of agency-published research and the IAB's standards work both suggest that the ROAS number a retail media dashboard reports may not reflect true incremental sales. Running at least one incrementality or holdout test before scaling spend — and ensuring owned channels like email and organic search are not being underinvested because dashboard numbers look favorable — are the clearest practical takeaways from the current debate.

The merchants most exposed to wasted spend, according to the source analysis, are those in mature, competitive categories running retail media budgets "on autopilot, optimizing to the ROAS number the network's own dashboard reports" without independent validation.
