Political Dollars Pour Into Battleground Markets As Fall Rush Begins.

The post-Labor Day political advertising rush has arrived, bringing a wave of spending that could make the next seven weeks especially lucrative for radio and other local media in the country’s most heavily contested markets.

AdImpact reports $510 million in political advertising aired nationwide during the first two weeks of September alone. Texas and Ohio each attracted more than $70 million, while Cleveland was the nation’s biggest local market with $19.6 million, followed by Detroit at $18.9 million and Atlanta at $16.6 million. And significantly more money is already lined up to follow.

AdImpact has tracked more than $613 million in future advertising reservations targeting just nine competitive Senate races. That represents only a portion of the political money already booked through Election Day and provides another indication that the election-year advertising market is moving into its most lucrative stretch.

The acceleration follows an August in which political spending had already jumped 63% from July. Historical trends suggest more dollars are coming. AdImpact says 52% of political advertising during the 2022 election year aired after Labor Day, meaning the biggest revenue-producing weeks of the midterm cycle are during the period broadcasters are now entering.

The spending surge is translating into a huge volume of commercials. AdImpact counted 373,000 broadcast political ad airings from Sept. 1 through Sept. 14, with taxation, healthcare and energy among the most frequently mentioned issues.

That growing volume could have implications well beyond the political category for stations. As campaigns and outside groups compete for inventory in the same handful of battleground markets, commercial advertisers will increasingly be competing with political buyers for available airtime. The pressure is likely to be especially noticeable in markets such as Cleveland, Detroit and Atlanta, which were already among the largest recipients of political advertising during the first half of September.

AdImpact is forecasting a record $11.6 billion for the full 2026 cycle. The latest numbers show $6.3 billion in political advertising had aired through Sept. 14, putting the 2026 cycle 37% ahead of the comparable point in the 2022 midterms. The widening spending curve is particularly notable as the election cycle enters the period when political advertising historically accelerates most sharply.

Few places illustrate the opportunity for local media better than Ohio. AdImpact says $161 million has already aired in the state’s Senate race, with another $146 million reserved. That puts combined aired spending and reservations at $307 million — second among elections this cycle only to California’s gubernatorial primary and $145 million ahead of the Maine Senate contest, currently the third-largest.

For Ohio broadcasters, it amounts to another enormous political advertising cycle just two years after the state hosted what AdImpact says became the most expensive Senate contest on record. AdImpact’s final analysis of the 2024 cycle found more than $540 million was spent on that race, helping make Ohio the third-largest political advertising state overall with more than $745 million spent.

There are already signs that the 2026 race could produce another substantial fall windfall. Ohio attracted $70.2 million in political advertising during the first two weeks of September, virtually matching Texas’ $70.3 million for the largest state total. Cleveland led all individual markets with $19.6 million.

Another developing source of demand is coordinated advertising. AdImpact says campaigns and congressional party committees currently have $25.7 million in future coordinated reservations across 41 races. The buying follows the Supreme Court's June decision eliminating federal limits on coordinated party spending.

Outside issue advertising is adding another layer of spending. Data centers, for example, have emerged as a growing advertising topic during the 2026 cycle. AdImpact says Build American AI recently placed $7.6 million in advertising nationally and across Ohio, Kansas, Wisconsin and Virginia supporting data-center development. The tracking firm has separately identified data centers as an increasingly prominent political advertising issue this year.
