Walmart Aligned Three Ad Businesses. It Says They’ll Keep Operating Separately.

Walmart used the Cannes Lions advertising festival to set out a single strategy for its three advertising businesses and to rename one of them. Sam’s Club’s Member Access Platform, known across the supplier base as MAP, becomes Sam’s Club Connect, a name that now mirrors Walmart Connect U.S. and Walmart Connect International. All three sit under Seth Dallaire, the Chief Growth Officer Walmart elevated to an enterprise role in its early-2026 reorganization, which placed Walmart Connect, Walmart+, Walmart Data Ventures, VIZIO, Sam’s Club’s ad platform, and the global Marketplace under one executive.

The Three Businesses Stay Separate. The Infrastructure Beneath Them Does Not.

The detail that matters most for media teams is what is not changing. Walmart was explicit that the three businesses will keep operating separately, each serving its own market, even as they align through shared technology and tooling. For a brand or seller running campaigns today, nothing about how a Walmart Connect buy is planned or measured changes this quarter. What Walmart is standardizing is the layer underneath the platforms, the shared data and measurement spine that has to exist before any cross-surface buying across the three businesses becomes possible.

Walmart Organizes This Deliberately Because Advertising Now Helps Fund the Model.

The timing reads against the numbers. Walmart’s fiscal 2026 results put global advertising growth at 46 percent for the year, reaching nearly $6.4 billion. In its most recent quarter, reported in May, global advertising grew 37 percent, and Walmart Connect in the U.S. grew 44 percent excluding VIZIO. CFO John David Rainey told investors that advertising and membership together now account for roughly a third of the company’s earnings, “very different from the Walmart of 10 years ago.” A business contributing that much of Walmart’s earnings is one the company organizes on purpose rather than letting it grow in three disconnected directions.

For Marketplace sellers, the sharper figure sits one level down. Walmart reported that seller advertising spend grew more than 50 percent in the same quarter, outpacing the headline Walmart Connect U.S. number. As Walmart standardizes the infrastructure beneath its platforms, sellers stand to gain the most from tooling and measurement that travel across surfaces, and carry the most exposure if the cost of competing for attention keeps climbing at that pace.

The Cross-Channel Push Is Already Showing Up Off Walmart’s Properties.

The vision the release describes, connecting activation and measurement across channels, is not aspirational. In recent weeks Walmart Connect has made its first-party data and measurement portable beyond its own surfaces. In May it signed Yahoo’s demand-side platform and the supply-side platform Magnite, letting advertisers activate Walmart audiences and buy VIZIO connected-TV inventory for the first time from outside Walmart’s own DSP. On June 11 it extended its work with Google, bringing Walmart Connect audiences and closed-loop measurement into Google’s Display and Video 360 starting with YouTube, with more platforms stated to follow. Both remain early, the Google piece a closed proof of concept, but together they put concrete form to the connected ecosystem the announcement describes: Walmart’s data and measurement as a layer advertisers can use from the platforms they already buy in.

Sam’s Club’s Rename Pulls a Working Measurement Engine Toward the Center.

The Sam’s Club Connect name is the visible piece of a quieter shift. Over the past year, MAP was built into a closed-loop network tied to verified member IDs, with measurement that connects ad exposure to sales inside the club and, through its rest-of-market analysis, to purchases beyond it. The rename pulls that capability toward the Sam’s Club master brand and, by Walmart’s framing, toward the commerce media vision it now shares with Walmart Connect. Adweek reported that Walmart hopes to replicate its advertising growth on Sam’s Club, a signal the smaller surface is being set up to scale, not just renamed. For suppliers who sell through both Walmart and Sam’s Club, two media relationships that have been managed separately are being positioned as parts of one system, at least in branding and stated strategy.

The two segments should read this differently. For 1P brand suppliers with upper-funnel and connected-TV budgets, portable Walmart data and measurement into outside platforms is the part to watch, because it changes where Walmart’s audiences can be reached. For 3P sellers concentrated in Sponsored Products inside Seller Center, the immediate mechanics are unchanged, but the same standardization signals where inventory, targeting, and measurement are heading.

None of this arrived without warning. The reorganization that put six growth businesses under one executive made a coordinated commerce media strategy a question of when, not whether. The open question for supplier media teams is how far the standardization runs. If shared technology, tools, and platforms eventually means one way to buy and measure across Walmart Connect and Sam’s Club Connect, that is the point at which this week’s vision turns into a change worth replanning around.
