Why This Matters: Strategic Advantages

Scale & Reach

The Amazon and Roku partnership significantly transforms the scale and reach of connected TV (CTV) advertising. By combining Roku’s extensive user base with Amazon’s Fire TV and Prime Video audiences, advertisers can now access a unified ecosystem that covers approximately 80 million authenticated households representing nearly 80% of the U.S. CTV market. This unprecedented scale is a game-changer for brands looking to maximize their campaign visibility across multiple streaming environments.

Instead of navigating fragmented platforms and disjointed user data, marketers benefit from consolidated, logged-in audiences that are easily targetable through Amazon’s DSP. This not only increases campaign efficiency but also improves reach quality by avoiding duplication. With broader visibility and a more refined delivery pipeline, advertisers can connect with more viewers while maintaining control over ad frequency and relevance. The result is a powerful opportunity to extend reach, improve ROI, and tap into premium inventory across two CTV giants.

Better Targeting & Measurement

One of the most impactful benefits of the Amazon–Roku partnership is the enhancement of targeting precision and measurement capabilities in the CTV space. By leveraging authenticated, logged-in user data from both Roku and Amazon’s Fire TV ecosystem, advertisers can now achieve deterministic targeting reaching real individuals rather than relying on probabilistic models. This ensures more accurate audience segmentation and message personalization.

Moreover, the collaboration enables deduplicated reach and frequency capping, so users aren’t overwhelmed with repeated ads across devices. All of this is executed through Amazon’s DSP, streamlining the process and centralizing control. Even more compelling is the ability to connect ad impressions to real business outcomes. Brands can measure performance across the full funnel from awareness to purchase especially when ad exposure leads to conversions on Amazon. This unprecedented level of accountability and insight gives marketers the tools to optimize campaigns, reduce waste, and drive higher ROI with every ad dollar spent.
