Yahoo and Comscore Launch Political CTV Product

Executive Signal Summary

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.
