What did Walmart Connect and Google announce?

Walmart Connect's first-party omnichannel shopper data is now activatable inside Google Display & Video 360 for YouTube campaigns, with closed-loop measurement that ties YouTube impressions to Walmart in-store and online sales.

How does this compete with Amazon DSP?

YouTube becomes a third measured surface for retail media, alongside Amazon DSP and Meta. Brands that wanted off-Amazon video with retail outcomes now have a path tied to Walmart sales rather than viewability only.

What is the early signal for Amazon sellers?

A competitor on a shared UPC starts running Walmart-attributed YouTube spend, and the first reading on the Amazon side is a sessions or BSR move on the listing. Tracking sessions and BSR weekly on hero ASINs is the cheapest watch.

Should brands shift Amazon ad budget to this new path?

Treat it as a test, not a swap. Tie any test budget to contribution margin on the Amazon SKUs it lifts inside the live P&L, then make the kill or scale call on margin, not on raw ROAS.

What's happening

Walmart Connect and Google announced a partnership that pipes Walmart's first-party omnichannel shopper data into Google Display & Video 360 for YouTube campaigns. Advertisers can now build YouTube audiences from Walmart purchase signals and measure those campaigns against in-store and online sales with closed-loop attribution. The official posts went live on blog.google and walmartconnect.com, with eMarketer and PPC Land covering the launch through June 11 to 15, 2026.

For Amazon brands, the read is direct. Walmart is using YouTube to compete head-on with Amazon DSP for the same upper-funnel video budget, and it is doing it with measured retail outcomes rather than viewability. The retail media duopoly is now a three-way fight on streaming inventory.

Why it matters for Amazon brands

Most Amazon-native brands run their off-Amazon media through Meta or Amazon DSP because those are the two surfaces where retail outcomes are measured cleanly. A Walmart Connect to YouTube path opens a third option that ties video impressions to Walmart in-store and online sales, and gives brands a way to test whether YouTube viewers convert at a Walmart shelf even if they never click. For multi-channel sellers that list on both Walmart and Amazon, that closed-loop measurement was the missing piece.

The competitive question is whether this pulls budget from Amazon Sponsored Brands Video and Amazon DSP. The honest answer is that any new measurable surface usually does, at least for the test budget. The bigger risk for Amazon-only brands is that YouTube starts showing measurable Walmart-attributed wins for competitors on the same shelf, and the case for off-Amazon experimentation gets sharper.

What you should do now

1.
Pull the list of shared-UPC SKUs across Amazon and Walmart
If a competitor brand starts running Walmart-attributed YouTube spend on a shared UPC, the first signal is a sessions or BSR shift on your Amazon listing. The shared list is the watch list.
2.
Re-read your Sponsored Brands Video and DSP video share
Inside Nova's PPC analytics, look at product-level ad spend on hero ASINs over the last 60 days. If most of your upper-funnel video spend sits in one surface, the new Walmart-to-YouTube path is a fair candidate to test alongside, not instead.
3.
Watch BSR drift on hero ASINs weekly
Competitor off-Amazon spend usually shows up first as a sessions lift, then a BSR move on the listing. The cheapest leading indicator is the BSR tracker on your own ASINs, refreshed weekly.
4.
Treat off-Amazon media as a contribution-margin decision
Any test budget shifted to off-Amazon video should be read 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.
