Midterms Break Ad Spending Records

The 2026 midterm election cycle has become the most expensive in American history for political advertising. Total spending and reservations have hit $11.21 billion, a figure that exceeds the $11.2 billion spent during the entire 2024 presidential race.

The cost of the 2022 midterms was $8.9 billion. This year's total represents a jump of roughly $2.3 billion over that previous midterm cycle.

Todd Belt, a political management professor at George Washington University, noted the high cost of late-stage advertising. He said it is not just a matter of volume but also the high price of buying spots this late in the campaign.

Texas holds the record for the most expensive nonpresidential race in U.S. history. AdImpact data shows the state has seen more than $560 million in spending and reservations for its Senate race. Ohio’s Senate contest has also crossed the $500 million mark, making it one of only three nonpresidential races to reach that level. The only other instance was Ohio’s 2024 Senate election.

Republicans hold a financial lead in political advertising. The party has spent approximately $5.18 billion this cycle, while Democrats have spent $4.77 billion, according to AdImpact.

Mike Ambrosini, chief of staff for the Republican National Committee, told The New York Times the party intends to use all available resources before Election Day. He said there is no saving money for a rainy day and that whatever can be deployed will be deployed.

Ken Martin, chair of the Democratic National Committee, pointed to grassroots fundraising as a sign of enthusiasm. He noted that hundreds of thousands of contributors giving $5, $10, or $15 indicate high excitement among supporters.

Billionaire donors have provided major funding to both sides. Elon Musk has contributed nearly $450 million to Republican causes, according to the Federal Election Commission. George Soros and Michael Bloomberg have contributed approximately $102 million and $84 million to Democratic efforts, respectively.

Belt described the election as a natural experiment to test the influence of money versus political messaging. He said Republicans have the money while Democrats have the voice against the administration.

Belt warned that going dark at the end of the campaign could be costly in close races. He said missing out on a few voters at the final stage could make all the difference.

Election Day is less than a week away.
