Walmart Connected TV Advertising Ignites Prime Day Data War

Walmart’s global ad business reached nearly $6.4 billion in fiscal 2026, while Amazon’s advertising business exceeded $70 billion over the latest 12 months. That gap explains why Walmart connected TV advertising is no side project. It’s Walmart’s attempt to move the purchase funnel onto the biggest screen in the home.

The trigger is sale week. Amazon Prime Day runs June 23 through June 26, while Walmart Deals started one day earlier and ends two days later, according to PYMNTS. U.S. online spending across retailers hit $8.3 billion on Prime Day’s first day, up 5.3% from a year earlier, Adobe Analytics said.

That number shows shoppers are still spending. It doesn’t show that discounts are the real prize.

Walmart connected TV advertising is the real Prime Day counterattack

The sale events are the visible fight. The deeper contest is over who controls the ad, the screen, and the data trail before a purchase happens.

Walmart’s agreement to buy Vibe.co, a French advertising startup, was reported by The Wall Street Journal at $1.4 billion. That deal matters because it slots into Walmart’s earlier $2.3 billion Vizio acquisition in 2024. Vizio gives Walmart a living-room screen. Vibe brings self-service software for smaller advertisers. Walmart Connect brings shopper data and measurement across online and in-store purchases.

Put together, Walmart is trying to make the TV screen behave less like passive media and more like a retail surface. A brand can show an ad, push a viewer toward a product, then ask whether that exposure turned into a sale.

That is the strategic point behind Walmart connected TV advertising. Walmart doesn’t have to beat Amazon only by extending sale dates or matching discounts. It can try to own more moments before shoppers even open a retail app.

The discount side still matters. XOOMAR has tracked how sale events are fragmenting across retailers in Anti-Prime Day Deals Undercut Amazon's Sale Prices, while the device category remains a key battleground, as seen in Prime Day TV Deals Punish 2026 FOMO With OLED Cuts. But Walmart’s bigger move is infrastructure, not markdowns.

The sale numbers show demand, not loyalty

The $8.3 billion first-day Prime Day spending figure is a strong demand signal. A 5.3% year-over-year increase across U.S. online retailers suggests shoppers are still willing to buy when the promotional calendar gives them a reason.

But XOOMAR analysis: that spending number doesn’t prove shoppers are becoming more loyal to any one retailer. It proves large sale events can concentrate demand. It also shows why retailers want longer windows. Walmart Deals beginning before Prime Day and ending after it gives Walmart more time to capture attention around Amazon’s tentpole event.

There’s another layer. Longer sale periods create more room for ads, sponsored placements, product discovery, and measurement. That matters more when a retailer’s ad business is becoming a profit engine.

Walmart’s advertising business is still far smaller than Amazon’s. The direction, though, is clear:

Walmart’s latest quarter added another signal: its global ad business grew 37%. That gives the company a reason to keep buying capabilities rather than treating advertising as an add-on to retail.

Vizio gives Walmart the screen, Vibe.co gives it more advertisers

Vizio is the hardware and connected-TV doorway. Vibe.co is the ad-buying tool Walmart needs if it wants more than big national brands using that doorway.

The source says Vibe’s software is designed to let smaller companies, including Walmart marketplace sellers, launch connected-TV campaigns without a large agency or media-buying staff. That matters because connected TV has traditionally been harder for smaller advertisers to access at scale.

If Walmart can make TV buying feel closer to buying search ads, it widens the advertiser pool. More advertisers can mean more demand for Vizio inventory. More campaigns can mean more data. More data can improve Walmart’s pitch to brands that want proof, not just reach.

NScreenMedia analyst Colin Dixon captured the core value of the model:

“Definitive attribution makes the ads far more valuable to brands.”

That’s the heart of Walmart connected TV advertising. The sell is not just that a viewer saw a patio set during a program. It’s that Walmart can tell a supplier whether exposure connected to a purchase online or in stores.

“Backyard Escapes” shows the pitch, and the risk

Walmart has already tested the model with “Backyard Escapes,” a Vizio program hosted by Tan France. Supplier products appeared inside makeover content, and viewers were directed toward Walmart’s patio-and-garden assortment.

Walmart said the value of merchandise sold during the related event was nearly 40% higher than a year earlier. Digital sales increased more than 50%, and nearly half of purchasers were new to the category.

Those are company-reported figures, not an independent audit. Still, they explain the pitch. Entertainment can become a storefront without forcing the viewer to start from a search bar.

The risk is just as obvious. If shoppable programming feels useful, brands will pay for it. If it feels like every show has become an infomercial, viewers may tune out the commercial layer even if they keep watching the content.

Amazon already has the larger commerce-media machine

Walmart is chasing a company that already operates a more mature version of the model.

Amazon connects Prime Video, Fire TV, and shopping data. The source says Amazon lets viewers add products to a cart from their television. In May, Amazon introduced Dynamic TV Creative, which changes an ad’s product details and call to action based on a viewer’s shopping behavior.

Amazon also said its interactive video formats generate four times as many add-to-cart actions and five times the purchase rate of standard streaming-TV campaigns. Those figures are also company-reported, but they show how Amazon frames the opportunity: video advertising that can move directly into commerce.

Walmart’s advantage, based on the supplied facts, is not scale. Amazon’s ad business is far larger. Walmart’s angle is that it can combine Vizio screens, Walmart Connect data, and online and in-store purchase measurement into one pitch for brands.

That’s why the Vibe.co deal matters. It suggests Walmart wants Walmart connected TV advertising to reach beyond major brands and into a broader base of advertisers that can buy, test, and measure campaigns with less friction.

The living room store now depends on proof, not novelty

Shoppable TV has a simple promise: reduce the distance between seeing and buying. The hard part is making that feel natural.

For Walmart, the upside is higher-margin ad revenue from existing customer relationships. Advertising lets a retailer earn more without carrying more inventory. That is why a business near $6.4 billion and growing 46% deserves more attention than a one-week sale calendar.

For brands, the appeal is measurement. They can buy media tied to real retail outcomes rather than broad awareness alone. The tradeoff is dependence on retailer-controlled systems for targeting, reporting, and shelf visibility.

For shoppers, the benefit is convenience if the ads are relevant and the purchase path is quick. The downside is a living room that feels more commercial. PYMNTS put it bluntly: the battle is over “the advertisement, the screen and the data trail that lead to a purchase.”

By the next summer sale cycle, the test won’t be whether Walmart can run deals against Prime Day. It can. The more important evidence will be whether Walmart expands Vizio-linked shopping formats, brings more smaller advertisers through Vibe.co, and reports repeatable sales lift beyond company-selected examples like “Backyard Escapes.”

If those signals appear, Walmart’s living-room strategy will look less like a media experiment and more like a second checkout lane. If they don’t, Amazon’s larger advertising machine keeps the advantage.

The Bottom Line

• Walmart is trying to close a massive retail advertising gap with Amazon by turning connected TV into a shopping channel.
• The Vizio and Vibe.co deals could help Walmart connect living-room ads directly to online and in-store sales data.
• Prime Day competition is no longer just about discounts; it is increasingly about who controls shopper attention before purchase.
