Walmart Connect is expanding retail media beyond retailer-owned websites and apps by bringing Walmart shopper audiences and sales measurement into live linear television, connected TV (CTV), and streaming audio. Announced on October 6, 2026, the expansion includes new and expanded partnerships with Warner Bros. Discovery, Yahoo DSP, and Spotify.
The announcement reflects a broader shift in commerce media: advertisers increasingly want to use retail audience data outside retail properties while understanding how media exposure relates to product sales. Instead of treating television, streaming audio, and digital advertising as completely separate investments, brands can explore ways to connect their audiences, buying workflows, and measurement.
According to Walmart Connect’s official announcement, the new and expanded capabilities include addressable targeting across selected live linear TV inventory through Walmart DSP, broader access to CTV inventory through Yahoo DSP, and Walmart audience activation and closed-loop measurement across Spotify advertising formats.
What did Walmart Connect announce?
At its Partner Connect event on October 6, 2026, Walmart Connect announced three related developments. Each gives advertisers another way to use Walmart audiences or measurement beyond traditional retail media placements.
| Partner or channel | What changed | Advertising implication |
|---|---|---|
| Warner Bros. Discovery | Selected live linear TV inventory becomes available through private marketplace deals in Walmart DSP, alongside the company’s streaming portfolio. | Advertisers can use Walmart audiences for addressable targeting across eligible television inventory. |
| Yahoo DSP and Magnite | The existing CTV integration is expanding from VIZIO to additional publisher inventory and moving into an alpha phase. | Advertisers can explore Walmart audience activation through an existing DSP workflow. |
| Spotify | US advertisers can access Walmart audiences and closed-loop measurement across Spotify audio, video, and display formats through Walmart DSP. | Brands can evaluate streaming audio and other Spotify placements against Walmart sales outcomes. |
These are distinct integrations rather than a single universal buying system. Inventory availability, buying arrangements, campaign eligibility, and measurement capabilities differ by partner and product.

1. Walmart Connect brings shopper audiences to live linear TV
The most notable part of the announcement is the expansion into selected live linear television inventory. Through private marketplace deals available in Walmart DSP, advertisers can access a Warner Bros. Discovery offering that combines streaming inventory with selected live linear TV placements. FreeWheel provides the programmatic technology enabling these deals.
The initial live linear inventory includes TBS, TLC, truTV, HLN, and Food Network, with additional inventory planned. Availability depends on the specific deals and inventory made accessible through the offering.
What is addressable advertising in linear TV?
Traditional linear television delivers scheduled programming to an audience through a broadcast or distribution system. Addressable TV advertising allows eligible households or audience segments to receive different advertisements within participating television environments.
Programmatic technology can help buyers discover, transact for, and manage eligible inventory through digital buying workflows. However, programmatic access to live linear TV does not mean every television impression is bought in a real-time auction, nor does it mean every household can receive a different advertisement.
In Walmart’s offering, the combination of retailer audiences, selected television inventory, and sales measurement is designed to help advertisers reach shoppers beyond Walmart-owned media properties.
Why does this matter to advertisers?
- Audience extension: Brands can seek to reach relevant Walmart customer segments in eligible television environments.
- Buying flexibility: Private marketplace deals provide a programmatic route to selected premium inventory through Walmart DSP.
- Commerce measurement: Advertisers can assess how television campaigns relate to Walmart sales, subject to the measurement methodology and available data.
- Cross-channel planning: Television and streaming investments can be evaluated alongside other media rather than exclusively through channel-specific delivery metrics.
2. Yahoo DSP expands access to Walmart audiences across CTV
Walmart Connect is also expanding its work with Yahoo DSP, with Magnite continuing to provide the sell-side technology supporting the integration. The earlier proof of concept connected Walmart audiences and closed-loop measurement with VIZIO CTV inventory.
The October 6 announcement says the integration is moving into an alpha phase and expanding beyond VIZIO to CTV inventory from additional publishers. This is an expansion of access, not evidence that every eligible publisher or advertiser already has general availability.
How does the integration fit into programmatic buying?
A demand-side platform (DSP) helps advertisers plan, activate, and optimize media purchases. A supply-side platform (SSP) helps publishers and other inventory owners manage and sell advertising opportunities.
In this integration, Yahoo DSP provides the advertiser’s buying environment, Magnite supplies the sell-side technology, and Walmart provides audience and retail measurement capabilities. The aim is to make shopper audiences available in an existing buying workflow instead of requiring advertisers to manage every activation through a separate platform.
What did the Hidden Valley Ranch campaign report?
Walmart Connect highlighted a proof-of-concept campaign for Hidden Valley Ranch, a brand owned by The Clorox Company. The campaign used Walmart audiences across VIZIO CTV inventory through Yahoo DSP.
Walmart reported the following results for the campaign:
- 55% incremental reach beyond linear TV.
- 27% lower CPM compared with similar-length 2026 CTV campaigns.
- 26% increase in add-to-carts.
- 3% brand lift.
Walmart’s published methodology references iSpot measurement for reach, Yahoo DSP campaign performance for CPM, Walmart Scintilla data for add-to-carts, and an Upwave brand-lift study. The reported measurement windows differ by metric.
These figures are campaign-specific results reported by Walmart Connect, not a guarantee of future performance or proof that every advertiser will achieve similar outcomes. The CPM comparison is against previous campaigns of similar length, not necessarily a randomized control group.

3. Walmart Connect extends audience activation to Spotify
The third development brings Walmart audience targeting and closed-loop measurement to Spotify advertising. Through Walmart DSP, US advertisers can access Walmart audiences across Spotify’s audio, video, and display formats.
This gives brands another option for connecting awareness and consideration campaigns with retail outcomes. For example, an advertiser could use streaming audio to reach an eligible shopper audience and then examine whether the campaign was associated with subsequent Walmart purchases.
The ability to measure an outcome does not establish that the advertisement caused that outcome. Sales may also be influenced by price, distribution, promotions, competitor activity, other media, and existing purchase intent.
Why streaming audio belongs in a commerce media strategy
Audio, video, display, CTV, and linear television offer different opportunities to reach people during different parts of their day. Combining these channels can broaden a campaign’s potential reach, but only when audience overlap, delivery, and measurement are evaluated carefully.
The Spotify integration is therefore important not just as another media partnership, but as an example of how retail audience data is being made available across formats that were traditionally managed separately from retailer-owned advertising.
What is closed-loop measurement in retail media?
Closed-loop measurement connects advertising exposure with a downstream outcome, such as a purchase recorded by a retailer. In Walmart Connect’s case, the relevant outcome is sales at Walmart, measured using its data and the methods available for each integration.
This can help advertisers understand whether an advertising investment is associated with product sales, including purchases that occur after someone sees an ad outside Walmart’s own website or app.
Attribution is not the same as incrementality
These concepts answer different questions:
| Measurement concept | Question answered | Important limitation |
|---|---|---|
| Reach | How many people or households were reached, according to the measurement method? | Reach estimates can vary by provider, universe, and methodology. |
| Attribution | Which sales or conversions were associated with an advertising exposure under the attribution rules? | An attributed sale is not automatically an additional sale caused by the ad. |
| Incrementality | How many additional outcomes occurred because of the advertising compared with an appropriate counterfactual? | Reliable estimates require a suitable experimental or analytical design. |
| Brand lift | Did measured brand perceptions or awareness change according to the study design? | Results depend on survey design, sample quality, and methodology. |
A strong retail media measurement strategy should not rely on attributed sales alone. Where practical, advertisers should use incrementality testing, holdout groups, or other suitable methods to estimate whether advertising generated outcomes that would not otherwise have occurred.
What this expansion means for programmatic advertising
Retail media is moving beyond retailer-owned inventory
Retail media networks historically emphasized sponsored products, retailer search, onsite display, and other placements close to the point of purchase. The wider commerce media model extends retailer audiences and measurement into channels such as CTV, audio, and television.
This can help advertisers bring shopper insights into upper-funnel campaigns while retaining a connection to retail outcomes. It also means retail media teams increasingly need to coordinate with brand media, programmatic, and measurement teams.
Buying flexibility is becoming a competitive factor
Advertisers often operate multiple DSPs, publisher relationships, and measurement systems. Making retail audiences available through existing buying tools can reduce workflow duplication and make it easier to integrate campaigns into broader media plans.
However, access through a familiar DSP does not remove all operational complexity. Teams still need to understand data permissions, audience definitions, deal terms, reporting differences, and the extent to which results can be compared across channels.
Measurement consistency matters more than a single dashboard
A unified view of media performance is useful only when the underlying metrics are understood. Television reach, streaming impressions, retailer-attributed sales, and experimental lift measures cannot automatically be combined as if they represented the same thing.
Advertisers should document which provider supplies each metric, how exposure is measured, what attribution window applies, and whether results represent correlation, attribution, or a causal estimate.
How advertisers should evaluate Walmart Connect’s new offerings
Before moving budget into a new retail media or cross-channel integration, advertising teams should evaluate the opportunity against a consistent set of questions.
1. Define the campaign objective
Decide whether the priority is incremental reach, brand awareness, consideration, sales, or customer acquisition. The objective determines which inventory and metrics are appropriate.
2. Confirm audience and inventory availability
Verify that the intended audience segments and media placements are available to the advertiser. Confirm whether the integration is generally available, in alpha, or limited to a proof of concept.
3. Establish a measurement plan before launch
Agree on the reporting provider, attribution window, eligible sales, reporting cadence, and any brand-lift or incrementality study before the campaign begins. This avoids choosing success criteria only after results are visible.
4. Compare costs on a consistent basis
CPM is calculated by dividing campaign cost by impressions and multiplying by 1,000. Compare CPM only when the inventory, geography, campaign duration, measurement basis, and relevant fees are sufficiently comparable.
For a refresher, see CPMinsider’s guide to CPM versus CPC advertising. A lower CPM can improve media efficiency, but it does not by itself prove that a campaign generated more incremental sales or profit.
5. Check reach overlap and frequency
When buying across linear TV, CTV, audio, and display, determine whether the same audience is being reached repeatedly or whether the campaign is adding genuinely incremental reach. Review available frequency controls and cross-channel measurement capabilities rather than assuming that every platform shares the same frequency data.
6. Evaluate outcomes against a meaningful baseline
Compare results with an appropriate historical campaign, control group, or test design. Account for seasonality, promotions, product availability, pricing, and other media activity that could influence sales.

Can Walmart shopper audiences be used in live TV advertising?
Walmart Connect announced addressable targeting across selected live linear TV inventory through private marketplace deals in Walmart DSP. The initial Warner Bros. Discovery offering includes TBS, TLC, truTV, HLN, and Food Network, with additional inventory planned.
What role do Yahoo DSP, Magnite, and FreeWheel play?
Yahoo DSP provides a demand-side buying environment for the CTV integration, while Magnite supplies the sell-side technology supporting that integration. FreeWheel enables the programmatic private marketplace deals for the Warner Bros. Discovery live linear TV offering. These are separate integrations.
What is closed-loop measurement in retail media?
It connects advertising exposure with retailer-recorded outcomes, such as sales. It helps advertisers evaluate the relationship between media investment and purchases, but attributed sales alone do not establish how many purchases were caused by the advertising.
Does a lower CPM mean a better advertising campaign?
Not necessarily. A lower CPM can indicate more cost-efficient impression delivery, but campaign quality also depends on reach, audience relevance, viewability where applicable, sales outcomes, incrementality, and the campaign objective.
Are all the new Walmart Connect integrations generally available?
Not necessarily. Walmart’s announcement describes the Yahoo DSP expansion as moving into an alpha phase. Advertisers should confirm current eligibility, inventory availability, and access with their Walmart Connect or platform representatives.
Conclusion: Retail media is becoming a cross-channel buying and measurement strategy
Walmart Connect’s October 2026 announcement illustrates how retail media is expanding beyond retailer-owned advertising inventory. By connecting shopper audiences and sales measurement with live television, CTV, and streaming audio, Walmart is giving advertisers more ways to connect brand exposure with retail outcomes.
The opportunity is not simply to buy more impressions. It is to improve audience reach, integrate buying workflows, and understand how advertising relates to sales across different channels. Delivering on that opportunity requires careful attention to inventory availability, measurement methodology, cross-channel overlap, and incrementality.
For programmatic and monetization professionals, the key development to watch is whether these integrations become easier to activate and whether their measurement produces comparable, decision-ready evidence for advertisers.
