Radio Positioned To Benefit As Political Ad Blitz Enters Final Stretch.

The political advertising business is heading into its final weeks and new figures from Kinetiq Political Insights offering some indication of how much money remains to be spent. While KPI isn't offering fresh radio numbers, its latest television spending data provides some clues about what radio stations may also be experiencing as the campaign enters its final weeks. It reports there is more than $1 billion in television advertising already scheduled to run before Election Day, as congressional races and deep-pocketed outside groups fuel another wave of spending across the country.

KPI’s analysis shows $1.87 billion in broadcast and cable television advertising has aired or been booked for October, with $1.01 billion scheduled for Oct. 15–31 alone. That puts more than half of the month's television spending into the campaign's final two and a half weeks, underscoring how much political advertising remains on the calendar.

The latest numbers reinforce KPI’s outlook for a record political advertising cycle. The firm continues to project $11.96 billion in total media spending during the 2025–2026 cycle, including $10.35 billion associated with this year's races.

House Races Gain Ground

Senate contests have dominated political advertising since Labor Day, accounting for $1.15 billion in advertising aired or booked since Sept. 1, compared with $913.6 million for House races. But that balance is shifting as Election Day approaches.

KPI says House races have $423.6 million in advertising scheduled after Oct. 14, exceeding the $379 million reserved for Senate contests during the same period. That suggests House campaigns will play an increasingly important role in sustaining political advertising demand through the final weeks.

That could benefit radio, which traditionally benefits from the localized nature of House campaigns. The figures also illustrate how political advertising dollars are spread. While Senate campaigns can generate enormous spending in a relatively small number of states, competitive House districts create advertising opportunities across a broader collection of local media markets.

While House spending is widespread, two Senate contests demonstrate just how much advertising money can be concentrated in individual markets.

In Texas, KPI reports $155 million in advertising since Labor Day, with another $45.5 million booked after Oct. 14. Meanwhile, Michigan's Senate race has generated $82.4 million in advertising since Labor Day, with another $34.2 million reserved after Oct. 14. These examples illustrate how a relatively small number of high-spending contests can create unusually intense demand for advertising inventory in particular states.

Outside Groups Drive Spending

Political action committees and other outside organizations remain a powerful force in the fall advertising marketplace. KPI says Republican outside groups have $430 million remaining on the books, while Democratic groups have $364 million reserved.

For broadcasters, the significance goes beyond the size of those budgets. Outside organizations generally pay higher advertising rates than candidates, who qualify for federal lowest-unit-rate protections during the political advertising window. KPI’s earlier analysis found that issue groups pay between 2.6- and 3.3-times candidate rates for comparable FM radio spots, depending on the daypart.

Record Spending Outlook Holds

Despite the latest shifts in advertising reservations, KPI is maintaining its September forecast of $11.96 billion for the full political cycle. The firm says the forecast range has narrowed considerably as actual spending and reservations provide a clearer picture of how the year will finish.

“We're still on pace for a record cycle; what changed is the range, now a third as wide,” its latest update says. For radio, the update maintains KPI’s earlier $230 million political advertising forecast.
