Midterm Ad Spending Has Surpassed $10B. Where Is the Money Coming From?

Political advertising spending for the midterms has reached a record $10 billion, projected to surpass $11.6 billion by Election Day, according to Ad Impact. This surpasses the previous high of $8.9 billion in 2022 and the $11.2 billion spent during the 2024 presidential cycle. The spending does not include other campaign expenses like staffing, travel, and voter outreach, but it does track one influential tool: television ads.

Research shows that a Senate candidate with a $2 million TV advertising edge could gain around 10,000 votes, potentially changing a tight race. Spending alone, however, doesn't guarantee victory, as experts note. Both parties have deep pockets this cycle, with Republicans significantly outspending Democrats in Senate races. Republicans spent $233 million to $121 million on broadcast TV ads in nine tight races, while Democrats' $947 million and $625 million in the same category are still growing.

Most funding comes from a few wealthy donors donating to super PACs. In the Texas race, for example, $500 million has been spent, making it the second non-presidential race to break the $500 million threshold. Elon Musk, the biggest individual donor to federal elections this cycle, gave $369 million to Republicans and $10 million to a Texas PAC supporting Republican James Talarico.

Talarico has outraised Republican Ken Paxton by roughly $50 million in donations, but Paxton has the advantage in TV ads. Ohio, another swing state, has seen over $460 million in ad spending, with $270 million backing Republican Jon Husted and $180 million for Democrat Sherrod Brown. Republicans outspent Democrats in aired election ads in Ohio by $41 million, making it the second-largest GOP advantage in battleground states.
