Roku–Google Deal Levels DSP Identity Playing Field
Roku announced a partnership with Google to join Google's Confidential Publisher Match, giving Display & Video 360 (DV360) buyers a deterministic, encrypted identity path into Roku Media. The integration enables encrypted first‑party data matching, improved household recognition and measurement via Campaign Manager 360 (CM360), and lets advertisers manage YouTube and Roku Media campaigns within the same platform without workflow changes. The move narrows a prior advantage held by Amazon DSP after Roku’s earlier OS-level identity deal with Amazon, which Roku–Amazon closed tests reported delivered a 3× ROAS improvement, 42% more unique reach and 27% lower frequency. Amazon retains a separate commerce advantage through purchase and shopping-intent data. Roku now maintains identity-level integrations with Google, The Trade Desk, Yahoo and Amazon, positioning deterministic, privacy-forward matching across major DSPs for CTV inventory.
A major platform partnership that gives another DSP (DV360) deterministic, privacy‑forward identity access to Roku CTV inventory — it reshapes programmatic competitiveness and measurement across major buying platforms.

Amazon and Roku Form Exclusive CTV Ad Alliance
Amazon Ads and Roku launched an exclusive connected TV (CTV) advertising alliance that will give marketers programmatic access to a combined reach of an estimated 80 million U.S. households via Amazon’s demand-side platform (DSP). The partnership, scheduled to roll out by Q4 2025, uses a shared ad identifier and a custom identity-resolution service to recognize logged-in viewers and unify authenticated inventory across Roku and Amazon Fire TV operating systems, including The Roku Channel and Prime Video. Early tests reportedly increased unique viewers ~40% and reduced ad over-frequency nearly 30%. Both companies present the deal as a scale and efficiency play for advertisers while raising industry attention about consolidation of CTV buying power.
Nielsen and Roku Expand TV Ad Measurement Partnership
Nielsen and Roku expanded a strategic partnership to integrate Roku’s first-party viewer data directly into Nielsen’s measurement suite, aiming to create a more accurate, de-duplicated currency across streaming and linear TV. The agreement gives Nielsen access to Roku’s footprint — which accounts for over 21% of U.S. TV viewing time — while Roku gains third-party-validated visibility via Nielsen’s Streaming Platform Ratings. The partnership builds on Roku’s 2021 acquisition of Nielsen’s Advanced Video Advertising business and leverages Nielsen’s Big Data + Panel system, which has been used as currency in Upfront transactions this year. Both companies framed the deal as a response to industry fragmentation and a step toward greater interoperability and measurement-driven ad performance.
Nielsen and Roku Strengthen Data Partnership for Advertisers
Nielsen and Roku have extended their cooperation with a multi-year data-sharing agreement that deepens integration between Roku's streaming data and Nielsen's measurement tools. Under the deal, Roku's TV data will feed Nielsen's Big Data + Panel for both linear and streaming ratings, while Roku gains access to Nielsen's streaming ratings. The arrangement aims to give advertisers a clearer view of audiences across Roku devices and third-party apps on Roku OS, using Nielsen's identity graph to deduplicate data and ensure accurate attribution. The partnership builds on a decade of collaboration, including Roku's initial measurement of video ads on Roku TVs and Nielsen's digital ad ratings-based audience guarantees; Roku once acquired Nielsen's advanced video advertising business in 2021. Nielsen notes Roku accounts for about 21% of TV viewing on Roku devices, and The Roku Channel ranks No. 2 among ad-supported streaming apps. The move reflects growing emphasis on audience and outcome measurement in fragmented TV environments.
