What Walmart Connect shipped at the 2026 Marketplace Seller Summit, and the meaningful takeaways for your brand.
Walmart Marketplace grew 50% YoY in Q1, its fastest pace in two and a half years, while the team rebuilt its ads platform to match that level of growth. At this year's Marketplace Seller Summit, Walmart Connect laid out a roadmap organized around seller goals rather than ad formats, consolidated its ad tools into Seller Center, and put AI bidding into alpha.
While all of that is worth knowing, none of the above was the most important thing said at the summit. What was most important dealt with an argument about how sellers set their goals in the first place, and that’s a discussion we've had with brands for two years. We tracked three shifts across the sessions we attended, and every one of them points the same direction: the efficiency metric you've built your brand’s Walmart program around is the thing holding it back.

WHY THIS SUMMIT MATTERED (BUT THE JOB IS EXACTLY THE SAME)
Every platform summit produces a feature list, and most of that list becomes table stakes within a year. The features Walmart announced are genuinely useful, and we'll get to them. But the job of a retail media program hasn't changed: find the customers who should buy your product, make them aware it exists, and make the second purchase easier than the first.
What changed this year is that Walmart now tells sellers, openly, that their own targets get in the way of that job. When a platform argues against efficiency, it's easy to be cynical about the motive. We think Walmart is mostly right, regardless, and the data they brought is the reason why.
TAKEAWAY #1: YOUR ROAS TARGET IS A SPENDING CAP IN DISGUISE
Walmart's example was a seller capped at $1,000 a day in spend, holding a $10.00 ROAS target. The account was performing well. But that account was also stuck, because it hit its ceiling every single day and stopped.
The seller lowered the target to breakeven, roughly $6.00. Spend climbed to $10,000 a day and daily sales reached $60,000. Same catalog, same products, same shoppers. The only variable that moved was the number the seller had told the platform to protect.
Sit with how much of that was already available. The demand existed the whole time. The auctions were there. The seller's own goal was the thing standing between the account and sixty times its daily revenue.
Here's the mechanism: an efficiency target doesn't just cut waste, it cuts everything below the line, including the profitable auctions sitting right underneath it. A $10.00 ROAS target instructs the platform not to bid on anything expected to return less than ten dollars per dollar spent. If your true contribution breakeven is $6.00, you have just declared every auction between $6.00 and $10.00 off limits. Those auctions were profitable, but you told the system to skip them.
- The diagnostic is simple. If a campaign spends its full daily budget at a comfortable ROAS, that target isn't protecting you from bad spend. It's deciding how big you're allowed to get.
- Capped campaigns hide their own upside. A campaign that spends out and stops has no idea how much demand it left behind, and neither do you.
- Waste and volume are different questions. One number can't answer both, and most Walmart accounts are quietly using ROAS to answer the wrong one.
- Set the target from your margin, not from your comfort. Breakeven is a contribution math question. Pull your real repeat rate and your real contribution margin by category, then decide what the floor should be. The reframe is sound; the specific number is yours to calculate.
- Buy the customer, then buy the category. Acquisition is the entry fee. Retention and expansion are where the $183 shows up, which means your brand media plan needs a job for each of them rather than one blended efficiency goal.
- Treat product content as media infrastructure. Walmart reported Sparky usage up 70% YoY, with those shoppers spending 40% more, and described a move from keyword search toward conversational, visual and problem-shaped queries. Their example was a shopper photographing a patch of yellowing lawn and asking what would fix it. Keyword search rewarded titles built for matching. Problem-shaped search rewards product data complete enough for a model to reason about. Thin content used to cost your brand conversion. Now it costs consideration, and you cannot bid your way back into a recommendation your brand was never eligible for.
- The lifetime value figures are category-bound. Covered above, and worth repeating because it's the number most likely to get lifted out of context. Treat the ratio as a prompt to calculate your own, never as a benchmark to hit.
- The 52% figure applies to consumables only. Walmart scoped it that way deliberately. Repeat-purchase categories respond to ad frequency in a way durables don't, so it shouldn't be carried across.
- The ROAS story is a single account. One seller, one category, one budget. A seller sitting on that much headroom was unusually under-spending to begin with, which is exactly what makes it a good slide. Your upside is real, and it is unlikely to be sixtyfold.
- "New sellers who advertise generate four times the average sales" is partly a selection effect. Sellers who choose to advertise tend to differ from those who don't in resourcing, content quality, and catalog readiness. Advertising is part of that gap rather than all of it.
- Sparky users spending 40% more is a correlation. Early adopters of a new shopping tool are plausibly heavier shoppers already. The behavior shift toward conversational and visual search is the real signal here. The spend premium is not yet evidence the tool caused it.
- Breakeven is not universal. A brand with thin unit economics and no repeat purchase behavior has very little lifetime value to borrow against. For that brand the efficiency target does real work, and lowering it just buys unprofitable volume faster.
- Expect your reported performance to move for reasons that are not performance. Deduplicated attribution is more honest, and it will also make some channels look worse the moment it lands, because credit counted twice is now counted once. Capture your baseline before the change, not after someone asks why display fell off a cliff. That is a reporting discontinuity, not a result.
- An alpha is an alpha. Target ROAS and Smart Performance will be tempting to hand a whole account to, especially while the platform tells you that your brand targets are too high. Give them a defined slice of budget, keep a control, and remember that automated bidding inherits whatever goal you feed it. Which puts you right back at the first question.
- Find the capped campaigns. Anything hitting its daily budget at a comfortable ROAS is the test candidate, because that is where unrealized volume lives.
- Lower targets in steps and judge them correctly. Move a small set rather than the account, then evaluate on incremental volume and contribution instead of blended efficiency, which will get worse by design.
- Turn on negative keywords and test video at the new floor. The first is cheap efficiency you have been unable to access. The second is mid-funnel reach that just repriced.
- Fix product content before AI-assisted discovery forces the issue. Complete titles, accurate attributes, real imagery, and copy that describes the problem you solve.
TAKEAWAY #2: YOUR BRAND BUYS A CUSTOMER, NOT A TRANSACTION
Walmart paired the ROAS argument with a harder push toward customer lifetime value, and the numbers carried it better than the theory did. Walmart put a first sale at $34 and a retained customer at $183, with every purchase after the first costing a fraction of the original acquisition. In consumable categories the compounding is clearer still: shoppers exposed to one, two, or three-plus ads spent 52% more on average.
One caveat before you write those numbers into a forecast. They came from a single advertiser in a high-ticket, considered-purchase category, and the absolute dollars do not transfer. A lip balm brand is not spending $34 to acquire a customer and will not book $183 in lifetime value, because its unit price is a fraction of a home renovation purchase.
What's interesting is that the correction doesn't necessarily run in the direction you'd expect. High-ticket durables carry large absolute values and low repeat frequency. Low-price consumables invert both, with small absolute values and far more frequent repurchase. Depending on your brand’s category, the multiple between first sale and lifetime value could easily be larger than the one Walmart showed rather than smaller. The shape of the argument survives the translation. The arithmetic is entirely yours to run.
Put those together and the problem with a first-sale ROAS target stops being tactical and becomes structural. If most of the value arrives on purchases two, three, and four, then optimizing to the first transaction means measuring the least valuable moment in the relationship and using it to set the budget. You are pricing a customer as though they will buy once, then receiving exactly the budget that assumption deserves.
This is also the honest case for why acquisition costs are allowed to look ugly. A first sale at breakeven is not a break-even customer. That initial cost is the entry fee on every purchase after it, and whatever that figure is in your category, it is not the one your ROAS target currently protects.
TAKEAWAY #3: NO SINGLE PLACEMENT DRIVES THE SALE ANYMORE
Walmart reported that shoppers touch two to six Walmart ads on average before buying, and that Marketplace sellers running multi-format media saw 85% more attributable sales. Sellers running full-funnel Sponsored Search grew GMV 1.55x more year over year than those running Sponsored Products alone. Adding onsite display to Sponsored Products produced a 45% median lift in new-to-brand ad-attributed sales.
If you manage a Walmart program for a brand, you have felt the tension this creates. Sponsored Products reports beautifully because it catches shoppers at the bottom of the funnel, where intent is already formed. Display and video report worse because they do the work that makes the bottom-funnel click possible, then hand the credit downstream. Judging them against each other on last-touch ROAS will always produce the same answer, and it will always be the wrong one.
WHAT WALMART SHIPPED
|
Area |
What changed |
|
Platform |
Ad Center is folding into Seller Center, so campaigns are built and optimized without leaving it. Negative keywords are finally available for excluding irrelevant or brand-misaligned search terms. |
|
Bidding |
Target ROAS and Smart Performance are both in alpha, with Smart Performance running one campaign and one budget across Sponsored Products and Brands. Max Sales and variant-level bidding on color, size and flavor are rolling out. |
|
Video |
The Sponsored Video minimum bid dropped from $0.80 to $0.50. |
|
Display |
Onsite retargeting is live against product page visits, search, browse, and cart abandonment. Gen-AI creative generation cut median production time about 80% in beta. The Vibe acquisition brings connected TV inventory into Walmart Connect. |
|
Brand |
Brand Asset Manager centralizes creative upload, approval and reuse. Brand Shop Spotlight buys above-the-fold placement during broad exploratory searches. |
|
Measurement |
A first-party identity graph now dedupes attribution across onsite and DSP, crediting one sale to one channel. Lifetime value reporting split by ad-exposed and non-exposed, customer penetration and new-to-brand are on the roadmap. |
Two of these will get less attention than they deserve. Negative keywords are the least glamorous item on the list and probably the highest return: sellers have spent years paying for search terms that were never going to convert and could not be excluded. And the $0.50 video floor is a 38% cut that changes what testing costs, which means mid-funnel experiments that failed an internal hurdle at $0.80 may clear it now.
There's also a shift worth noting for positioning. Walmart described a deliberate move away from national brands and toward unique and emerging ones, framing Marketplace as where specialized assortment gets tested without a broad inventory commitment. They reported that new sellers who advertise generate four times the average sales of sellers who don't. If you represent an emerging brand, the platform's growth strategy depends on brands like yours succeeding.
WALMART CONNECT: THE STELLA WAY OF THINKING
We read this roadmap as a single instruction with three parts.
A NOTE ON WHOSE NUMBERS THESE ARE
Every figure above is Walmart's: presented by Walmart, about advertisers on Walmart. That doesn't make them wrong. It does mean several of them need reading carefully before they end up in a plan.
None of this is a reason to discount the direction of travel, but a reason to do your own math before you move a target.
WHERE WE'D PUSH BACK
We think Walmart is mostly right. We would not take all of it at face value.
THE TLDR FOR YOUR BRAND’S WALMART PROGRAM
Efficiency tells you how well you spent the money you spent. It says nothing about the money that you didn't spend. Those are separate questions, and one ROAS target has been quietly answering both of them in most Walmart accounts for years. The formats will keep changing. This is the part with a shelf life.
What we would do, on a brand account, in the next ninety days:
If your brand’s Walmart program has been flat while your ROAS has looked great, those two facts are almost certainly related.
