Amazon DSP vs. Criteo Commerce Max in 2026: Which Retail Media Platform Wins?

Retail media has officially eaten the digital advertising industry. In 2026, U.S. retail media ad spend is projected to surpass $61 billion, according to eMarketer’s June 2026 Retail Media Forecast — a figure that would have seemed absurd five years ago. Two platforms are increasingly at the center of agency budget conversations: Amazon DSP and Criteo Commerce Max. One is the undisputed gorilla backed by the world’s largest product catalog and first-party purchase intent data. The other is a scrappy, open-internet challenger that has quietly assembled a coalition of 225+ retailer data partners — including Walmart Connect, Target’s Roundel, Best Buy Ads, and Instacart — into a single unified buying surface.

For DTC brands scaling beyond owned channels, Amazon sellers looking to capture off-Amazon demand, and agency media buyers trying to justify retail media line items to CFOs, the choice between these two platforms is not academic. It’s a budget allocation decision with real margin implications. We dug into both platforms — talking to agency leads, brand-side media buyers, and platform reps — to give you the most operationally honest comparison available heading into Q4 2026.

What Does Each Platform Actually Offer in 2026?

Amazon DSP has undergone significant expansion since its 2022 rebrand push. As of mid-2026, it offers programmatic display, video (including streaming TV via Prime Video), audio, and out-of-home placements — all powered by Amazon’s first-party shopper data covering roughly 220 million active U.S. customer accounts. The platform’s defining advantage remains its closed-loop attribution: brands can connect an ad exposure directly to an Amazon purchase event, often within a 14-day window.

Criteo Commerce Max, launched in its current unified form in late 2024, operates differently. It’s a demand-side platform built on top of Criteo’s Commerce Media Platform, which aggregates shopper data from over 725 retailer and publisher partners globally. In the U.S., its most consequential data partnerships include Walmart Connect (first-party purchase data), Costco, Kroger Precision Marketing, and Albertsons Media Collective. Brands activate Commerce Max through a single interface and reach consumers across the open web, in-app, and increasingly on connected TV — without being confined to a single retailer’s walled garden.

How Do the Audience Targeting and Data Depth Compare?

This is where the platforms diverge most sharply — and where Amazon DSP’s moat is most defensible. Amazon’s purchase intent signals are unmatched in product-level specificity. You can target consumers who searched for “stainless steel French press” in the last 30 days and did not purchase. That granularity, built on real transaction data rather than modeled segments, is genuinely difficult to replicate.

“Amazon’s in-market audiences are still the highest-quality retail signal we have access to in any DSP,” said Melissa Tran, VP of Retail Media at Tinuiti, in an interview earlier this month. “The problem is you’re paying a premium to reach people who are already on Amazon, and the attribution tells you what you want to hear — not necessarily what’s true.”

Criteo’s counter-argument is breadth and openness. Its Commerce Audiences product aggregates purchase signals from its retailer network and layers in Criteo’s proprietary Shopper Graph — which the company claims covers 725 million active shoppers globally. For brands selling across Walmart.com, Target.com, or DTC simultaneously, Commerce Max offers something Amazon DSP structurally cannot: cross-retailer audience intelligence without requiring an Amazon relationship.

“We’re not trying to be Amazon,” said Brian Gleason, Criteo’s Chief Revenue Officer, at the Cannes Lions Commerce Stage in June 2026. “We’re building the connective tissue between every retailer’s data and every brand’s media budget. That’s a different bet, and we think it’s the right one for the next decade of retail media.”

What Does the Pricing and Minimum Spend Reality Look Like?

Amazon DSP has historically required a $35,000 monthly managed-service minimum when running through Amazon’s own team. Self-service access via the DSP console is available to sellers and vendors directly, but meaningful scale typically demands agency intermediaries or Amazon’s own managed service. CPMs for display run $4–$9 on-Amazon; off-Amazon display averages $2–$5; STV (streaming TV) placements are commanding $25–$40 CPMs in 2026, up roughly 18% year-over-year.

Criteo Commerce Max has positioned itself as more accessible. Minimum managed spends start around $15,000–$20,000 per month depending on the agency relationship, and self-service access is available with no enforced floor. CPMs vary widely by retailer data overlay: open-web display without retailer data runs $1.50–$3.50; Walmart-data-targeted segments are fetching $6–$10 CPMs, with Kroger and Albertsons grocery audiences sitting in the $8–$14 range due to category scarcity.

For brands with budgets under $50,000 per month, Criteo’s lower floor makes it more accessible. For brands spending $250,000+ monthly in retail media, both platforms are typically running simultaneously inside larger agency holding group setups at shops like Publicis Commerce and GroupM’s Choreograph unit.

How Do Attribution and Measurement Stack Up?

Attribution remains the most contested and politically charged dimension of retail media in 2026. Amazon DSP’s closed-loop attribution model — correlating ad exposure to Amazon purchase events — is clean, fast, and deeply satisfying to look at in a dashboard. It is also, as critics frequently note, entirely self-reported. Amazon is the ad seller, the measurement vendor, and the retailer all at once. There is no independent MRC-accredited verification of Amazon DSP’s attribution methodology.

Criteo has leaned hard into third-party measurement as a differentiator. Commerce Max integrates natively with IRI (now Circana), NielsenIQ, and LiveRamp’s measurement suite. For CPG brands with brick-and-mortar distribution, this matters enormously — Circana’s in-store sales lift measurement tied to Criteo’s digital ad exposure is a capability Amazon DSP cannot replicate for off-Amazon retail channels.

That said, Criteo’s cross-retailer attribution still has seams. When a consumer sees a Commerce Max ad on the open web and purchases on Walmart.com three days later, Criteo’s view-through attribution window and Walmart Connect’s own attribution models don’t always agree — creating the kind of double-counting headaches that frustrate brand-side analysts.

Which Platform Performs Better for Which Seller Type?

Agency media buyers we spoke with were consistent in their segmentation recommendations:

• Amazon-first brands (FBA sellers, 1P vendors): Amazon DSP remains the default for lower-funnel retargeting and competitive conquesting. The purchase-signal quality for Amazon-native shoppers is simply not replaceable. Brands like Liquid I.V. and Native have publicly cited Amazon DSP as a core component of their always-on Amazon ad architecture.
• Omnichannel DTC brands selling at Walmart and Target: Criteo Commerce Max is increasingly the platform of record. The ability to activate Walmart Connect and Target Roundel data inside a single DSP seat — without managing separate retail media relationships — is a genuine operational efficiency for brands running lean media teams.
• CPG and grocery brands: Criteo’s Kroger and Albertsons data partnerships, combined with Circana measurement, make Commerce Max the stronger platform for brands where in-store lift is the primary KPI.
• Marketplace sellers under $5M annual revenue: Neither platform is likely the right investment yet. Amazon Sponsored Display or Walmart Sponsored Products are better starting points before graduating to DSP-level complexity.

What Do the Market Share and Financial Trajectories Tell Us?

Amazon’s advertising services segment generated $14.7 billion in Q1 2026 alone — up 19% year-over-year — with DSP contributing a growing but undisclosed share of that total. Amazon holds an estimated 75–78% share of all U.S. retail media ad spend, per eMarketer and Insider Intelligence data as of July 2026.

Criteo reported €1.04 billion in revenue for full-year 2025, with its Commerce Media segment (which includes Commerce Max) growing 31% year-over-year — its fastest-growing business unit. The company’s stock (CRTO on Nasdaq) has recovered significantly from its 2022 lows, trading around $42–$46 as of early August 2026, buoyed by the retail media tailwind and several new retailer data agreements signed in H1 2026.

The honest verdict heading into Q4 2026: Amazon DSP wins on signal depth for Amazon-specific funnels and streaming TV reach. Criteo Commerce Max wins on flexibility, independent measurement, and cross-retailer data breadth. The most sophisticated operators — brands like Solo Brands and Thrasio’s rebuilt portfolio — are running both simultaneously with distinct KPIs assigned to each seat. For everyone else, start with where your product actually sells, and let attribution requirements guide the investment.
