Navigating Privacy-First Retail Media: Strategies for Consent Validation

A $166B advertising channel is running on consent collected for a different business.

Retail media networks generate 50 to 70 percent operating margins by activating loyalty and e-commerce data across programmatic, CTV, and clean rooms. The consent underneath most networks was captured years ago, for a loyalty program, not for an advertising business. Under most state privacy laws, those are different processing purposes.

The pressure to close that gap is not just regulatory anymore. CPG advertisers are starting to ask networks to prove consent validity before committing budgets. The IAB released specific guidance on retail media privacy in June 2025. The retailers who can answer definitively will capture share. The ones who cannot will not.

Our Strategic Guide to Privacy-First Retail Media covers the consent architecture that travels with the data, the six places it usually breaks, and a 90-day plan to close the gaps. Written by the team behind 1,000+ compliance implementations.
