Amazon DSP (Demand-Side Platform) Private Marketplace is a dedicated channel for advertisers who want control over ad placement quality and inventory type, not just impression volume. While most DSP spend flows into the open exchange where competition is high, Private Marketplace offers access to premium inventory with different performance characteristics. Understanding 2026 benchmarks for this channel can help you allocate DSP budget more strategically.
