Comscore and Yahoo DSP Revolutionize CTV Political Advertising
Comscore and Yahoo DSP announced a partnership to bring Proximic Political Audiences to Connected TV (CTV), aiming to unify linear and streaming campaign strategies for political advertisers ahead of the 2026 U.S. election cycle. The solution lets agencies and activation partners, including MiQ’s political division, operationalize Proximic Political Audiences at scale across premium CTV inventory. The offering aligns CTV targeting with verified linear TV exposure and leverages Comscore’s local market measurement alongside Yahoo ConnectID to improve incremental reach and cross-screen coordination. Proximic Political Audiences are available for both PAC and candidate campaigns and can be measured at the local market level to enable targeted spend and accountability. The collaboration is positioned to help political advertisers coordinate messaging across linear and streaming environments for more efficient voter engagement.
Provides a cross‑platform CTV solution for political advertisers ahead of the 2026 election cycle, improving local-market measurement and linear-to-streaming coordination, but is a sector-specific product launch rather than industry-wide infrastructure change.

Yahoo and Comscore Launch Political CTV Product
Comscore and Yahoo DSP announced Proximic Political Audiences, a product that maps Comscore’s linear-TV exposure data into streaming reach via Yahoo’s DSP to help political advertisers find incremental CTV audiences across all 210 U.S. DMAs. The stack pairs Yahoo ConnectID as a deterministic identity layer with MiQ’s political division as the designated activation partner. The announcement comes amid multiple political streaming plays — including DirecTV’s DirecTV Elect and Ampersand’s TrueStream Political — as vendors compete to capture an expected $2.5 billion in 2026 streaming political ad spend within a projected $10.8 billion U.S. political ad market. Vendors emphasize cross-screen coordination to avoid redundant delivery, but it remains unclear whether district-level, down-ballot precision can be reliably achieved during the 2026 cycle.

The solution promises campaigns live in under 24 hours, ZIP-code-level targeting, localised measurement by county/DMA/ZIP, creative compliance tools, and auction-efficient pricing. OpenX also announced a first‑to‑market partnership with Givsly to integrate privacy‑safe first‑party signals from a database of 500+ non-profits to build values-based voter audiences (e.g., environmental, Hispanic support, women’s empowerment). Curated CTV publishers named include Newsweek, Plex and Xumo, and turnkey political inventory packages will be available to buyers via DSPs such as Basis, IQM and StackAdapt. The combined product aims to stabilise CPMs, improve audience resonance in contested ZIP codes, and expand premium political CTV inventory access.
Walmart outlines plan to dominate TV advertising
Walmart is aggressively expanding its retail media ambitions into TV advertising. The retailer, which acquired Vizio for $2.3 billion two years ago, is now building a streaming ecosystem that includes the recent acquisition of adtech firm Vibe.co for $1.4 billion. Walmart Connect, the retailer's ad business, is pitching itself to non-endemic advertisers, leveraging Vizio's smart TV OS and Vibe.co's performance-focused streaming platform. New partnerships with Skydance and Spotify aim to extend reach, and the Yahoo DSP integration is moving to alpha. Walmart's U.S. ad business grew 38% YoY in Q2, and the company is positioning its first-party commerce data as the key differentiator for TV ad targeting and measurement, even for brands that don't sell at Walmart.
