TLDR
- Walmart is remodeling 650 stores and opening 20 new ones in 2026. ALDI is adding 180+ locations with a redesigned store format.
- The investment is not just about square footage. It is about building stores that function as intentional interfaces for discovery and purchase.
- Retail media has been largely a digital conversation. The in-store environment is where the majority of purchase decisions still happen.
- As stores become more observable and measurable, in-store exposure becomes a signal, not just an impression.
- The brands winning retail media in the next cycle will close the loop between offsite, onsite, in-store, and transaction data.

Walmart just announced it is remodeling 650 stores and opening 20 new locations this year. ALDI is pushing into new markets with 180+ store openings and a redesigned footprint built for modern shopper flow. Pathmark is re-entering with a tighter, more deliberate format.
The headlines read as expansion. The actual story is about design intent.
The Store as Interface
For the past several years, retail media has been a digital media conversation. Sponsored search on Walmart Connect. Display ads on Instacart. Offsite audience targeting using purchase data. Closed-loop attribution tied to transaction IDs. All of it measurable, all of it happening on screens.
Meanwhile, the physical store kept running more or less the same way it always had.
That is changing. When Walmart redesigns a store, it is not just moving shelving. The layout decisions — how shoppers enter, how they move, where they pause, what they see at eye level — are increasingly informed by behavioral data. The store is being engineered the same way a landing page gets optimized.
Once you see it that way, the store stops being a distribution point and starts being an interface. Discovery, consideration, and conversion all happen in the same physical environment. The analogy to digital is not a stretch. It is the whole point.
Where Measurement Comes In
Walmart's Scintilla API, launched this week, gives media partners and agencies access to 500 retail data elements. The explicit goal is connecting what happens in stores to what happens in media — before, during, and after a visit.
That is a significant move. It signals that Walmart is not treating in-store and digital retail media as separate channels. It is building the infrastructure to make the physical environment observable at a data level that was not possible three years ago.
The brands that have built strong in-store presences with ALDI or Walmart are sitting on a different kind of asset than they realize. Every shelf placement, every endcap, every display is generating exposure that is now, slowly, becoming quantifiable.
For cannabis brands operating in legal retail, this trajectory matters directly. Dispensaries are not Walmart, but the same behavioral logic applies. A shopper who picks up a product, reads the label, puts it back, then circles back five minutes later is communicating something. Right now, that signal disappears. It does not have to.
The Gap Brands Need to Close
The opportunity is to connect what happens before the store, inside the store, and after the purchase into one system. Offsite media that drives awareness. In-store placement that captures consideration. Transaction data that closes the loop.
Most brands are not operating that way. Offsite campaigns run separately from trade marketing. In-store programs are managed by a different team than digital. Attribution stops at the store door.
That gap is becoming more expensive to maintain as the retailers themselves close it. Walmart, ALDI, and the next generation of physical retailers are building the measurement infrastructure. The question is whether the brands inside those stores build the strategy to match.
What This Means for Cannabis Retail
The cannabis retail environment has always been more controlled than general retail — smaller footprints, staffed interactions, regulatory constraints on signage and merchandising. That has also meant less behavioral data and less connection between dispensary-level activity and broader media strategy.
The direction of travel in mainstream retail points toward closing that gap. As dispensary tech matures — from in-store screens to budtender tablets to loyalty integrations — the in-store environment becomes more readable. That is not a surveillance conversation. It is a performance conversation.
The brands investing in understanding in-store behavior now, even at a basic level, will be better positioned when the measurement infrastructure catches up.
The store is not the last mile of a media campaign. For an increasing number of consumers, it is the signal that makes the rest of the campaign legible. Build accordingly.
