Walmart Connect Surpasses $6B in Ad Revenue as Retail Media Matures

Walmart Connect quietly crossed a milestone that would have seemed implausible three years ago: its retail media network surpassed a $6 billion annualized revenue run rate in Q2 2026, according to figures Walmart disclosed during its August 12 earnings call. The number puts Walmart Connect on a trajectory that rivals where Amazon Advertising stood in 2021 — and it is sending ripples through every layer of the ecommerce advertising ecosystem, from mid-market Shopify sellers running omnichannel campaigns to enterprise agencies managing nine-figure media budgets.

For DTC founders and marketplace operators who have spent the last five years treating Amazon Sponsored Products as the only retail media game worth mastering, the data is a forcing function. Walmart’s first-party shopper data now covers more than 145 million unique weekly U.S. shoppers across its physical stores and digital properties, giving Connect an audience-match advantage that is increasingly difficult to dismiss.

What Is Driving Walmart Connect’s Sudden Acceleration?

Three structural shifts are compounding to accelerate Connect’s growth. First, Walmart+ membership crossed 42 million households in June 2026, creating a logged-in, cookieless audience that advertisers can target with the same deterministic precision that Amazon DSP has offered for years. Second, Walmart’s acquisition of Vizio in late 2024 has matured into a functioning connected-TV inventory layer, allowing Connect to serve shoppable ads directly on smart-TV home screens — a capability Amazon has been building toward with Fire TV but has not yet fully productized for third-party sellers. Third, Walmart’s supplier co-op model, which historically locked ad dollars inside a Byzantine manual process, has been largely replaced by a self-serve interface that opened to all Walmart Marketplace sellers in March 2026.

“The Vizio integration was the unlock nobody was talking about. We’re now running mid-funnel CTV ads that close on Walmart.com within 72 hours, and the attribution is cleaner than anything we’ve seen on any other platform.” — Meghan Torrez, VP of Performance Media at Brainlabs U.S.

Torrez, whose agency manages Walmart Connect budgets for eleven consumer goods brands with collective annual GMV exceeding $800 million on the marketplace, says her team has shifted roughly 18 percent of total retail media budget from Amazon to Walmart since January 2026. That reallocation is not unique to Brainlabs. According to a July 2026 survey of 340 agency media directors conducted by eMarketer, 31 percent reported increasing Walmart Connect spend by more than 15 percent year-over-year, while only 9 percent reported decreasing it.

How Are Amazon Sellers Responding to the Shift in Retail Media Spend?

For sellers who built their entire customer acquisition infrastructure around Amazon’s advertising console, the adjustment is operationally complex. Amazon’s flywheel — where ad spend drives ranking, which drives organic velocity, which compounds returns — does not translate cleanly to Walmart’s marketplace mechanics. Walmart’s search algorithm still weights in-store velocity and supplier relationships in ways that disadvantage pure-play third-party sellers who lack a wholesale footprint.

Nevertheless, a growing cohort of Amazon-native brands are making the transition work. Nate Ginsberg, co-founder of Constellation Brands Collective, a brand aggregator managing 14 Amazon-native labels, told Ecommerce Times that his team now runs parallel catalog strategies on Walmart for seven of those brands, with dedicated Connect budgets ranging from $40,000 to $180,000 per month per brand.

“We treat Walmart like Amazon 2019. The CPCs are still rational, the competition is lighter in most categories, and the first-party data is genuinely good. Brands that wait another 18 months are going to face the same auction inflation we saw on Amazon after COVID.” — Nate Ginsberg, co-founder, Constellation Brands Collective

The category dynamics vary sharply. Health and wellness, pet supplies, and home goods are seeing the steepest CPC increases on Connect as more sellers enter those verticals. Apparel and electronics remain relatively undercompeted, in part because Walmart’s catalog depth in those categories still lags Amazon’s, limiting organic demand that would otherwise attract advertiser interest.

What Tools Are Operators Using to Manage Cross-Platform Retail Media?

The operational complexity of running simultaneous campaigns across Amazon Advertising, Walmart Connect, Instacart Ads, Kroger Precision Marketing, and Target’s Roundel has created an opening for a new class of retail media management platforms. Pacvue, which has supported both Amazon and Walmart for several years, reported a 67 percent year-over-year increase in Walmart Connect managed spend on its platform through H1 2026. Perpetua added native Walmart Connect campaign management to its enterprise tier in May 2026 after months of beta testing with select agency partners. Skai — formerly Kenshoo — has positioned its unified retail media dashboard as the default choice for enterprise CPG brands managing budgets across six or more networks simultaneously.

• Pacvue: Strongest automation depth for Walmart Sponsored Products; dayparting and bid rules now parity with Amazon feature set as of Q1 2026.
• Perpetua: AI-driven goal-based bidding extended to Walmart in May 2026; best suited for sellers already on its Amazon infrastructure.
• Skai: Preferred by enterprise CPG for cross-network budget pacing and unified incrementality reporting; requires dedicated onboarding for Walmart Connect attribution.
• Quartile: Gaining traction among mid-market Shopify sellers expanding to Walmart for the first time; lower minimum spend thresholds than Pacvue or Skai.

Attribution remains the industry’s open wound. Walmart Connect’s closed-loop measurement — which tracks ad exposure directly to Walmart.com and in-store purchase — is robust within the Walmart ecosystem, but multi-touch attribution across Walmart and off-platform channels is still immature compared to what Amazon Attribution has offered since 2020. Several agencies have resorted to media mix modeling with vendors like Measured and Northbeam to estimate Walmart Connect’s contribution to overall brand revenue, rather than relying on platform-reported ROAS.

Is Walmart Connect a Real Threat to Amazon’s Retail Media Dominance?

Context matters here. Amazon Advertising generated an estimated $56 billion in revenue in 2025, according to eMarketer projections. Walmart Connect’s $6 billion run rate represents roughly 10 percent of that figure. In absolute terms, Amazon is not under existential pressure. But the direction of travel is what concerns Amazon’s advertising leadership. Amazon’s retail media growth rate slowed to approximately 17 percent year-over-year in Q2 2026, while Walmart Connect grew at 38 percent over the same period.

The competitive response from Amazon has been visible. Amazon Sponsored TV — its CTV ad format for third-party sellers — exited beta in February 2026 and is now available to sellers with active Brand Registry. Amazon also quietly expanded its off-Amazon display inventory through its demand-side platform, allowing sellers to reach Walmart.com and Target.com shoppers who previously browsed their Amazon listings — a defensive move designed to keep brand budgets inside the Amazon ecosystem even when consumers shop elsewhere.

“Amazon is not sleeping. But they’ve spent a decade telling sellers that everything they need is inside the Amazon walls. Walmart’s pitch is the opposite — come reach our shoppers wherever they are. That’s a different philosophy, and some brands are ready for it.” — Andrew Lipsman, independent retail media analyst and former eMarketer principal.

What Should DTC Founders Do With This Data Right Now?

For DTC brands that sell exclusively on their own Shopify storefronts and have no marketplace presence, Walmart Connect is not yet directly actionable — you need a Walmart Marketplace listing before you can run Connect ads. But the broader implication is significant: the retail media landscape is fragmenting in ways that reward brands with multi-marketplace catalog presence and punish those locked into a single platform.

Operators who are already on Walmart Marketplace and spending less than $10,000 per month on Connect are, by most agency benchmarks, underinvested. The self-serve interface that launched in March 2026 has eliminated most of the friction that previously required a Walmart supplier development manager to unlock basic sponsored product campaigns. Minimum daily budgets start at $100, and the learning algorithm reaches statistical significance within two to three weeks in most mid-volume categories.

• Audit your current Walmart catalog for listing quality score — Connect ads amplify organic ranking signals, so a weak listing will underperform regardless of budget.
• Request Walmart’s Category Intelligence reports through your supplier or marketplace account manager; these now include share-of-voice benchmarks by subcategory that are more granular than Amazon’s Brand Analytics equivalents.
• Test Walmart’s Sponsored Brands video format before CPC inflation arrives — average video CPCs on Connect were $0.38 in July 2026, compared to $1.12 for equivalent placements on Amazon.
• Implement Walmart’s conversion API (launched April 2026) on your DTC site to enable off-site retargeting through Connect’s DSP — the setup requires roughly four hours of developer time and meaningfully improves match rates.

The structural forces that built Amazon Advertising into a $56 billion business — first-party data scale, closed-loop attribution, and a captive seller base that must advertise to maintain organic visibility — are now present in Walmart’s ecosystem in sufficient concentration to warrant serious allocation. Whether Walmart Connect reaches $10 billion by 2028, as some analysts project, or plateaus as Amazon reinforces its moat, the window for rational, pre-inflationary media buying on the platform is open now. For operators paying attention to the numbers, that is the operational signal worth acting on.
