TL;DR: Retail media is one of the fastest-growing areas of US digital advertising, and agentic advertising infrastructure is beginning to shape how brands negotiate and govern retail media deals at scale.

What Retail Media Is

Retail media is advertising sold by retailers (or platforms with retail-adjacent first-party data) to brands that want to reach shoppers at or near the point of purchase. Amazon Advertising is the most prominent example, but US retail media networks now include Walmart Connect, Target Roundel, Kroger Precision Marketing, and dozens of others.

The defining characteristic of retail media is the quality of the first-party data. Retailers know what shoppers bought, how often, at what price, and in what context. That data underpins targeting that is substantially more reliable than third-party cookie-based approaches, which is why retail media has grown rapidly as broader programmatic targeting has become less precise.

How Agentic Advertising Intersects With Retail Media

Most US retail media buying today is still handled through managed service relationships or self-serve platforms specific to each retailer. As the market matures and brands increase spend across multiple retail media networks simultaneously, the manual overhead of managing those relationships separately becomes significant.

Agentic advertising infrastructure addresses this by enabling buy-side agents to negotiate directly with sell-side systems across multiple retail media networks, using a consistent deal governance framework regardless of which retailer's inventory is being accessed.

This matters because retail media deals, particularly those involving first-party data overlays and shopper targeting, involve parameters that are more complex than standard programmatic buys. An agent mandate can encode brand-specific constraints around product category exclusions, audience overlap limits, and share-of-voice targets, and apply those constraints consistently across every retail media negotiation.

What Changes for US Brands

For US brands with significant retail media budgets, agentic infrastructure addresses three specific problems.

First, consistency. A brand buying across Amazon, Walmart, and Target simultaneously cannot easily enforce the same targeting and brand safety parameters across three different managed service relationships. Agent mandates provide a single governance layer that travels with the buy, regardless of which network the agent is negotiating with.

Second, accountability. Most retail media networks provide seller-reported measurement. Agentic infrastructure, where deals are governed by bilateral records rather than seller-held transaction data, provides a framework for independent verification of what was agreed and what was delivered.

Third, scale. As retail media networks proliferate, the manual work of managing individual network relationships limits how much budget brands can efficiently deploy. Agents that can negotiate across networks simultaneously remove that constraint.

Where Alkimi Fits

Alkimi's marketplace infrastructure is not retail media-specific. It is neutral infrastructure for agent-to-agent deal negotiation wherever bilateral deal records and mandate governance add value. As retail media networks adopt agent-compatible interfaces, the Alkimi model, where both buyer and publisher agents hold a bilateral DealSheet, provides the accountability layer that brand CMOs and finance teams need.

For US brands evaluating how to scale retail media spend without losing governance, the question of agentic infrastructure and bilateral deal records is the same question whether the counterpart is a retail media network or a traditional publisher.
