Retail media networks have aggregated impressive ad inventory, but remain operationally fragmented. Amazon, Walmart, and Target each control their own data and refuse meaningful interoperability, forcing brands to rebuild campaigns separately.

Without standardization, retail media risks becoming a channel tax rather than a data-enabled competitive advantage.
