Walmart Connect in 2026: The Retail Media Challenger Finally Showing Its Teeth

For years, Walmart Connect was the retail media story everyone acknowledged but nobody fully believed. Its audience was real, its store footprint unmatched, and its first-party data theoretically valuable — but the ad platform itself was clunky, the self-serve tooling lagged Amazon Advertising by several years, and agencies quietly steered budgets elsewhere. That narrative is changing in 2026, and changing fast enough that serious operators need to pay attention.

Walmart Connect now accounts for an estimated $4.8 billion in U.S. ad revenue through Q1 2026, according to eMarketer’s latest retail media sizing report — up from roughly $3.1 billion in 2024. That growth trajectory puts it firmly in second place among domestic retail media networks, ahead of Instacart Ads, Kroger Precision Marketing, and Target’s Roundel. It is still well behind Amazon Advertising’s dominant position, which eMarketer pegs at approximately $56 billion in annual U.S. revenue, but the gap in platform capability and agency trust is narrowing in ways that matter operationally.

What Has Actually Changed Inside Walmart Connect’s Ad Stack?

The honest answer is: more than most sellers realize, and less than Walmart’s marketing suggests. The most meaningful upgrade over the past 18 months has been the buildout of Walmart Connect’s self-serve Sponsored Search interface, which now supports campaign-level budget caps, dayparting controls, negative keyword lists, and bulk editing via spreadsheet upload — features Amazon sellers have taken for granted since 2019 but that were conspicuously absent from Walmart’s tooling as recently as late 2024.

Walmart also launched its Sponsored Display product across the full open web in early 2026, using its first-party purchase data to target shoppers off Walmart properties via programmatic channels. The product runs through The Trade Desk’s infrastructure — a partnership that dates back to 2021 but has been significantly deepened — and gives brands the ability to retarget Walmart shoppers across connected TV, display, and online video without requiring a Walmart.com ad buy as an anchor.

“The DSP integration with The Trade Desk is the part of Walmart Connect that CPG brands and DTC crossovers are actually excited about right now. You’re finally getting real reach extension off Walmart’s first-party data, not just sponsored placements inside a walled garden.” — Kieley Taylor, Global Head of Partnerships, GroupM

The platform also rolled out a closed-loop measurement suite called Walmart Luminate Ads in Q4 2025, giving advertisers access to post-campaign purchase attribution tied to actual Walmart transaction data rather than modeled proxies. For sellers running both in-store and Walmart.com, this represents a genuine capability gap closed — one that agencies say was a recurring objection during media planning conversations.

Where Does Walmart Connect Still Fall Short?

The gaps are real and worth naming directly. The biggest structural weakness is audience scale on Walmart.com itself relative to Amazon. Walmart’s e-commerce monthly active user base sits at roughly 120 million U.S. shoppers, compared to Amazon’s 160-plus million — a meaningful gap when you’re running Sponsored Products campaigns that depend on impression volume to generate statistically significant optimization signals.

Keyword-level reporting remains shallower than Amazon’s. Walmart Connect does not yet surface search term reports at the granularity that tools like Helium 10, Pacvue, or Perpetua have built their Amazon workflows around. Third-party software support is improving — Pacvue added full Walmart Connect campaign management parity in late 2025, and Perpetua followed in Q1 2026 — but the data fidelity underneath those tools is still catching up.

• No equivalent to Amazon’s Brand Analytics: Walmart Connect lacks a self-serve market basket analysis tool, making competitive intelligence gathering harder for sellers without direct Walmart buyer relationships.
• Sponsored Brands video still limited: Walmart’s video ad placements are available but restricted to select categories and require creative review timelines that can run 7-10 business days, versus Amazon’s near-instant approval for compliant assets.
• Minimum spend thresholds: Managed service campaigns through Walmart Connect require $25,000 monthly minimums, locking out most sub-$5M GMV sellers from the more sophisticated audience targeting features.
• Attribution window alignment: Walmart Connect’s default 14-day attribution window creates comparison problems for brands trying to normalize ROAS across Amazon and Walmart using tools like Northbeam or Triple Whale.

“We run about $600K a month in Walmart Connect spend for a handful of our CPG clients, and the measurement story is getting better — but when a client asks me to pull a search term report with the same depth they get out of Amazon Brand Analytics, I still have to apologize.” — Megan Conahan, EVP, Direct Agents

How Are Marketplace Sellers Actually Using Walmart Connect in 2026?

The most sophisticated Walmart marketplace operators are running a two-tier strategy: using Sponsored Products to defend their own item pages and attack close competitor ASINs on high-intent search terms, while layering Walmart’s off-site display product via The Trade Desk integration to drive upper-funnel awareness among shoppers who haven’t yet entered a Walmart purchase flow.

Category dynamics matter enormously. In grocery, household essentials, and OTC health — categories where Walmart’s in-store and online penetration is deepest — sellers report Sponsored Search CPCs running 30-45% below comparable Amazon placements, according to agency benchmarks compiled by Tinuiti. In consumer electronics and apparel, that gap narrows substantially, and in some subcategories Amazon CPCs are actually lower due to deeper competition on Walmart’s thinner SKU catalog.

Walmart’s item page architecture also creates a distinct optimization surface. Unlike Amazon, which uses a heavily structured A+ content system, Walmart’s item pages support rich media modules that can be updated more rapidly — a detail that content-forward DTC brands have learned to exploit. Brands like Olly Vitamins and Native have been quietly investing in Walmart item page content as a performance lever alongside their ad spend.

Who Is Running Walmart Connect’s Strategy, and Does Leadership Instill Confidence?

Walmart Connect is led by Rich Lehrfeld, who joined Walmart in 2019 and has overseen the platform’s most aggressive growth phase. Lehrfeld comes from an agency and brand background — he spent years at American Express in marketing leadership — and his public positioning consistently emphasizes measurement credibility and closed-loop attribution as Walmart Connect’s primary differentiation from pure-play programmatic alternatives.

“Our advantage is the data — 90% of American households shop with Walmart over the course of a year. No other retail media network can say that. What we’re building now is the infrastructure to make that data actionable at scale for every advertiser, not just the top 50 CPG companies.” — Rich Lehrfeld, SVP & GM, Walmart Connect

Below Lehrfeld, Walmart has invested heavily in its agency development team over the past 24 months, adding dedicated holding company liaisons and launching a Walmart Connect Certified Partner program that now includes Tinuiti, Flywheel Commerce (now part of Omnicom), Pacvue, and a handful of regional performance agencies. The certification framework mirrors Amazon’s Advertising Partner Network model closely — possibly too closely, critics argue, given that Walmart’s platform nuances warrant different training content rather than an Amazon-adjacent playbook applied wholesale.

What Does the Competitive Landscape Mean for Amazon-First Sellers?

The most immediate strategic question for Amazon-focused sellers is whether Walmart Connect has crossed the threshold of operational maturity that justifies meaningful budget diversification. The answer in mid-2026 is: yes, with category caveats.

For sellers in grocery, home goods, pet, baby, and health — where Walmart’s shopper overlap with their target demographics is strongest — allocating 15-25% of retail media budgets to Walmart Connect is defensible and increasingly measurable. Agencies like Tinuiti and Flywheel are now recommending formal Walmart Connect testing protocols for any brand doing more than $2M annually on Walmart.com, rather than treating it as an afterthought activated only during Walmart’s deal events like Walmart Deals in July or Black Friday season.

For apparel, luxury-adjacent categories, and high-consideration electronics, the math is murkier. Walmart’s shopper demographics skew value-conscious in ways that don’t always align with premium positioning, and the category-level CPC competitiveness advantage diminishes. Sellers in these verticals report better incremental returns staying Amazon-heavy and experimenting with Target’s Roundel for premium audience access.

• Flywheel Commerce (Omnicom): Now routes a significant share of its Walmart retail media client spend through Walmart Connect’s managed service, with dedicated Walmart strategy teams across its Chicago and New York offices.
• Tinuiti: Published benchmarks in April 2026 showing 2.3x ROAS on Walmart Sponsored Products for home goods clients, outperforming Amazon Sponsored Products in the same category by 18%.
• Pacvue: Achieved full campaign parity for Walmart Connect management in its platform — including budget pacing alerts, daypart scheduling, and bid automation rules — making it the most complete third-party tool for multi-marketplace PPC operators.

Is Walmart Connect a Genuine Threat to Amazon Advertising’s Dominance?

Not yet, and probably not in the 12-18 month window. Amazon’s ad flywheel — where ad revenue funds fulfillment infrastructure, which drives Prime adoption, which expands the ad-relevant audience, which attracts more sellers — is structurally self-reinforcing in a way Walmart Connect cannot replicate at the same speed. Amazon also has a 5-7 year head start on measurement sophistication, third-party tool integrations, and the seller education infrastructure that makes its ad products operationally accessible to merchants at every scale.

But “not a genuine threat to Amazon’s dominance” and “worth serious investment” are not mutually exclusive positions. Walmart Connect in 2026 is a legitimate second channel for the right categories and the right merchants — one that has finally cleared the minimum viable platform threshold that separates a credible retail media network from a checkbox spend. The brands and agencies that treat it as such, rather than waiting for it to become Amazon-equivalent before engaging, are likely to build structural advantages in Walmart search placement and audience data that will compound over time.

The next 18 months will be defined by whether Walmart Connect can close the measurement gap fast enough to win meaningful budget share from brand-level media dollars — not just performance marketing reallocation. If Walmart Luminate Ads delivers on its attribution promise at scale, and if the managed service minimum thresholds come down to open the mid-market, Walmart Connect’s trajectory becomes significantly more disruptive. Watch this space closely heading into Q4 2026.
