Asda partners with Amazon Ads to launch US-developed retail ad tech

This partnership shifts the retail media landscape by allowing a major non-Amazon retailer to adopt Amazon’s mature ad-tech stack, reducing the technical barrier for brands to execute multi-platform campaigns. For the streaming ecosystem, this integration signals a move toward a more interoperable 'commerce media' framework where first-party retail signals can be more easily bridged with digital video environments. The use of Amazon’s standardized tools outside its own ecosystem could accelerate the consolidation of ad-buying workflows. Watch for whether Amazon’s DSP begins incorporating Asda-specific retail data to target connected TV audiences across the UK market throughout 2027.

The expansion of the Amazon Retail Ad Service (ARAS) into the UK reflects a broader strategic pivot to license internal ad technology to third-party retailers. Originally introduced in beta during CES 2025, per Silicon Republic and Amazon Ads announcements in January 2025, ARAS was designed to compete with established ad-tech providers like Criteo and Epsilon. While initial US partners included specialty retailers such as iHerb and Tilly’s, the Asda deal represents the service's first major international footprint and its first deployment within a high-frequency grocery category outside North America.

This technology play is occurring as the UK retail media market undergoes rapid expansion and consolidation. According to IAB UK reporting from March 2026, UK retail media spend reached £3.8 billion in 2025, growing 18% year-on-year, and is forecast to hit £6.6 billion by the end of 2025. Asda’s digital overhaul is part of a wider turnaround strategy. In May 2026, as reported by the London Stock Exchange, Asda announced an extensive ecommerce infrastructure partnership with Ocado Group to replace its legacy systems with the Ocado Smart Platform (OSP) starting in 2027.

Industry analysts at IAB UK note that 'off-site' and video activations are expected to grow two to three times faster than on-site placements as brands seek closed-loop measurement that links ad exposure to actual transactions. By adopting Amazon's ad stack, Asda secures access to a sophisticated machine learning engine that can process millions of weekly customer signals. This move is critical as Asda fights to defend its 11.5% market share against encroachment from discounters like Aldi, which reached 10.8% in mid-2026, per Retail Week and InternetRetailing.
