Citigroup

Citigroup's entry into commerce media with a new advertising platform is the cycle's clearest signal that retail media is expanding beyond retailers into transaction-rich financials leveraging first-party purchase data. Coverage framing it around new products and fee growth ahead of earnings positions media as a diversification and monetization play, not an experiment. Strategically, it validates the commerce-media thesis while raising new questions about measurement credibility outside traditional retail inventory.
