US Midterms 2026: Judge Rochon bars five DHS-funded TV adsBackground
AdImpact is an advertising intelligence firm based in Alexandria, Virginia, that tracks television, radio and digital ad placements and spending. It began in politics as Advertising Analytics and has since added commercial advertising. News outlets routinely cite its estimates of what campaigns and outside groups spend on air.
Its figures sit beside the FEC filings in any reading of the 2026 ad war. Party committees moved money into coordinated buys after NRSC v. FEC because those buys qualify for the cheaper Lowest Unit Charge rate, and outside groups filed $44.10m of Independent expenditures in Ohio's Senate race in one week. AdImpact estimates show where that money lands on screen.
In October 2026 AdImpact valued five government-funded DHS television ads at $21.7m, a figure that federal court reporting relied on.
