Retail media infrastructure is crossing old boundaries

A preview edition on retail ad service expansion, commerce signals in streaming, and the next layer of onsite media.

3 stories 2 min read

This preview edition follows one pattern across three recent announcements: retail media infrastructure is moving beyond the retailer’s own stack. Distribution, measurement, and onsite formats are becoming partnership questions.

Asda brings Amazon’s retail ad service outside the US

What happened: Asda will introduce Amazon Retail Ad Service across its online grocery and George platforms. Amazon Ads said the rollout will begin in phases from the fourth quarter of 2026, making Asda the first retailer outside the US to use the service.

The read: The decision gives Asda access to an established ad stack without asking the retailer to recreate every layer internally. It also gives Amazon a route to scale its retail media infrastructure through other retailers.

The signal: Retail ad technology is becoming a distribution business, not only an owned-inventory business.

Commerce signals move deeper into streaming delivery

What happened: Amazon Ads and FreeWheel introduced Outcome Optimizer for streaming TV publishers. Amazon Ads said the capability combines publisher content with Amazon signals through AWS Clean Rooms, then uses predictive models to optimize guaranteed deals toward advertiser outcomes.

The read: The integration puts commerce intelligence closer to the ad server, where publishers already manage delivery. That reduces the distance between retail signals and premium video inventory.

The signal: The strongest offsite retail media products will fit existing publisher workflows before asking buyers to adopt new ones.

Lidl expands the surface area of onsite media

What happened: Criteo and Lidl expanded their partnership to add more onsite retail media formats. Criteo said the work includes sponsored product and display placements across Lidl’s digital properties.

The read: Onsite media is moving from a narrow search product toward a broader inventory portfolio. The commercial opportunity grows, but so does the need to protect the shopping experience.

The signal: Retailers will need one measurement language across onsite formats before they add more inventory.

What changes first when retail media infrastructure travels across companies: the buying workflow, the measurement model, or the margin?
