For years, most brands treated Walmart the way they treated the shelf: a place to win the moment of purchase. You bought Sponsored Search, defended your product pages, and called it a retail media strategy. And to be fair, that worked when Walmart's ad stack was mostly search and the only real lever was keyword coverage.

That era is closing. Over the past year Walmart Connect has quietly rebuilt the two ends of its display business, onsite and offsite, and stitched them together around one thing it owns that almost no one else does: first-party purchase data at national scale. The headline feature everyone is talking about is retargeting. And while it’s exciting, the real story is what retargeting signals about where Walmart retail media is going, and why a search-only approach now leaves money on the table.

Here the Code3 take on what changed, why it matters, and what brands should do about it before the rest of the category catches up.

What Changed With Walmart Connect Display and Retargeting?

Two shifts happened in parallel, and they are more powerful together than apart.

On the onsite side, Walmart Connect moved display out of the managed-service back room and into a self-serve platform. The Display Self-Serve model removed spend minimums and opened up auction-based buying on unreserved inventory. The newest self-serve onsite display platform, announced in late July 2026, layers on AI-powered optimization, advanced audience targeting, real-time forecasting and inventory visibility, and on-demand reporting. Brands can now build, launch, and optimize display campaigns themselves, in the UI, with the same audience tools that used to require a managed team and a big check.

Those audience tools are the part that matters. Walmart's onsite display targeting now spans behavioral segments (including brand buyers, category buyers, in-market shoppers, lapsed buyers, propensity models), contextual and persona targeting, and custom audiences built on Walmart's own shopper data.

Retargeting lives inside that toolkit. Brands can re-engage shoppers who viewed a product page but did not buy, win back lapsed buyers, and defend your detail pages from competitors who are one click away.

On the offsite side, Walmart went the other direction and opened up. After moving beyond an exclusive DSP model, Walmart Connect spent 2026 extending its first-party audiences and closed-loop measurement to more platforms. A June 2026 tie-up with Yahoo's DSP and Magnite marked the first time advertisers could activate Walmart customer data outside the Walmart DSP, with a clear priority on connected TV inventory through Vizio, the CTV platform Walmart bought for 2.3 billion dollars in 2024. The message to the market: Walmart's audiences are no longer trapped in one buying tool, and offsite is where Walmart wants to grow.

Connected TV is where that ambition is most visible. In August 2026 Walmart completed its acquisition of Vibe.co, a self-serve streaming TV platform built to get small and mid-sized brands into CTV without a big-agency setup, in a deal reported at 1.4 billion dollars. Read it next to the 2.3 billion dollar Vizio purchase and the intent is obvious. Vizio gives Walmart the screens and the viewership data; Vibe.co gives advertisers an easy front door to buy them.

As Walmart Connect GM Ryan Mayward framed it, the goal is to help advertisers "connect with customers more seamlessly across streaming, shopping and the broader commerce journey." In other words, Walmart is assembling a self-serve, measurable CTV business that runs on the same shopper data as its display, and it is spending billions to make it easy to access.

Put the two together and you get the actual capability. The same Walmart shopper you retarget on a product page can be followed off Walmart entirely, onto the open web, streaming, and social, using the same identity and the same purchase signals, and then measured back to sales at Walmart. That is a closed loop, and it is rare.

Why Walmart Retargeting Matters for Brands

It is tempting to file retargeting under "new ad type" and move on. That undersells it.

Retail media's whole promise is first-party data plus closed-loop measurement. Walmart has more of both than almost anyone, because it sees what people actually buy, in stores and online, across a huge share of American households. Until recently that advantage was bottled up: onsite display was hard to access, and offsite was locked to a single platform. Both bottlenecks are gone. When the data advantage becomes easy to activate across the funnel, the channel stops being a search tactic and becomes a full-funnel media platform that happens to be attached to a retailer.

The timing is not subtle either. U.S. offsite retail media spending was projected to hit roughly 17 billion dollars in 2026, up nearly 30 percent year over year. Walmart is building the pipes for that money on purpose. Brands that keep spending only on search are competing for the bottom of the funnel while Walmart quietly builds the top.

There is a competitive wrinkle worth naming: easy self-serve access cuts both ways. When retargeting is a dropdown, competitors get it too, and the shopper who just looked at your product is now a target for the brand next to you on the shelf. Retargeting is quickly moving from an edge to table stakes. The edge shifts to whoever structures it well.

What Brands Should Do Now

At Code3, our point of view is straightforward: stop treating Walmart display as a leftover line item and start running it as connected, full-funnel media. A few concrete moves:

Build the loop, not the silo. Design onsite and offsite together so a shopper who engages offsite gets met onsite, and a shopper who bounces off a product page gets followed offsite. Managing them as separate budgets wastes the one thing that makes this work, which is shared identity.

Defend your detail pages first. The cheapest, highest-intent retargeting available is re-engaging people who already viewed your products and protecting those pages from conquesting. If you do nothing else this quarter, do this.

Lean into offsite and CTV early. Walmart is prioritizing offsite growth and pouring capital into CTV, from Vizio's screens to the Vibe.co self-serve buying layer, and it is still early enough that inventory and attention are less crowded than search. This is no longer a big-brand-only channel. Early movers get to learn the mechanics before costs rise.

Insist on measurement. The reason to run this on Walmart rather than a generic DSP is closed-loop attribution back to real sales. Hold the channel to that standard, and use it to settle the incrementality question rather than to justify last-click wins.

Reset how you buy. Self-serve auctions, AI optimization, and real-time forecasting reward active management and testing, not set-and-forget managed insertions. The teams that treat Walmart display like a living auction environment will beat the ones who treat it like a reservation.

The Bigger Picture

Retargeting is the visible tip of a deeper change. Walmart is turning its purchase data into a full-funnel media system that runs both on and off its properties, and it is making that system easy enough for any brand to use. That is good news and a warning at the same time. The capability is democratized, which means the advantage no longer comes from access. It comes from strategy: how you connect the funnel, how you sequence messaging, how honestly you measure, and how fast you learn.

The brands that win the next phase of Walmart retail media will not be the ones who simply turned retargeting on. They will be the ones who understood that Walmart just handed the whole industry the same new toy, and built a smarter plan for it.
