Walmart Connect lays out vision for global commerce media era

What's happening

On June 22, 2026, Walmart used the opening day of Cannes Lions to set out what it calls the next era of global commerce media. The corporate update on corporate.walmart.com lays out an expanded Walmart Connect with Sam's Club Member Access Platform folded deeper into the offer, broader first-party-data pipes into Google Display & Video 360 for YouTube, and a new pitch to global brand advertisers for closed-loop measurement against in-store and online sales.

The headline number behind the pitch is that Walmart Connect ad revenue tripled in five years to roughly $6.4 billion in 2025. The strategic message is that retail media is no longer just a lower-funnel performance line. Walmart wants its first-party shopper data to underwrite upper-funnel video on YouTube and CTV inventory the way Amazon has been doing with Amazon DSP and Prime Video.

Why it matters for Amazon brands

For brands that sell on both Amazon and Walmart, this is the moment the retail-media duopoly turned into a three-way contest for the same video budget. Walmart is now able to tell a competitor brand on a shared shelf that a $50k YouTube test can be measured against actual Walmart purchases inside seven days, and a similar story is coming for Sam's Club. The Amazon-only test you ran last quarter just gained a comparable.

For Amazon-only brands, the second-order risk is sharper than the first. Walmart-attributed YouTube spend on a competitor SKU usually shows up first as a sessions drift on your Amazon listing, not as a Walmart unit move. The shelf is shared even when the budget is not.

What you should do now

1. 1.

   List shared-UPC SKUs across Amazon and Walmart

   If a competitor brand starts running Walmart-attributed video against a UPC you both sell, the cheapest early signal is on your Amazon listing. Pull the shared-UPC list and tag the SKUs as a weekly watch list.

2. 2.

   Re-baseline upper-funnel video share

   Inside Nova's PPC analytics, read product-level ad spend on hero ASINs over the last 60 days. If most of your video budget is concentrated in one surface, treat the Walmart-on-YouTube path as a fair test alongside, not a replacement.

3. 3.

   Watch BSR drift on hero ASINs weekly

   Competitor off-Amazon spend usually shows up first as a sessions lift, then a BSR shift on the listing. The cheapest leading indicator is the BSR tracker on your own ASINs refreshed weekly.

4. 4.

   Read every test against contribution margin

   Any test budget shifted to off-Amazon video should be measured against contribution margin on the Amazon SKUs it lifts, not raw ROAS. Tie the test back to the live P&L at SKU level so the kill or scale call is honest.

How Nova helps

Nova gives brand managers and agencies per-SKU PPC analytics and contribution-margin P&L across the 21 Amazon marketplaces it supports. When Walmart Connect spend lifts competitor SKUs on shared shelves, the Amazon-side impact lands in sessions, units, BSR and margin before it shows up in any retail-media dashboard.
