A senior Target executive publicly acknowledged that most brand partners are not yet on board with the retailer's new ad metric designed to connect spend directly to sales outcomes, exposing a trust gap at the heart of retail media. American Express published a formal framework enabling card issuers to verify and authenticate purchases initiated by AI shopping agents on behalf of consumers, addressing the core authorisation problem blocking mainstream agentic commerce.
