The 2026 Political Ad Tally So Far: $3.8B and Counting
Political advertisers have spent nearly $900 million more targeting congressional races this cycle than at the same point in 2024, an explosive increase driven by cash-rich outside groups and a rapidly changing advertising landscape.
A new report from ad-tracking firm AdImpact underscores just how expensive the 2026 midterms have become. Here are some key takeaways from the data:
The GOP Has a Cash Advantage. And It Shows.
Republicans were always expected to face a tough political climate in 2026. Yet they’ve maintained one clear advantage throughout the cycle: money.
In seven of the eight most competitive Senate races – those in Alaska, Iowa, Kansas, Maine, Michigan, New Hampshire and Texas – Republicans hold the aired spending advantage, according to AdImpact data. All told, GOP advertisers have aired around $1.3 billion in Senate ads, while Democrats have aired about $964 million.
The Republican spending advantage marks a reversal from 2024, when Democrats outspent Republicans on Senate advertising by about $200 million. In fact, the GOP’s current Senate spending edge eclipses 2022 levels, when Republican advertisers outpaced Democrats by about $122 million.
On the House side, however, Democrats are the ones with the ad spending advantage. Of the $1.5 billion spent in House races this cycle, Democratic advertisers account for $787.3 million, while Republicans account for about $678.9 million. Democrats also led in House advertising in 2024 and 2022, according to AdImpact.
Republicans Are Taking Advantage of a Recent Supreme Court Decision
When the Supreme Court handed down a decision in National Republican Senatorial Committee v. Federal Election Commission this summer, conventional wisdom held that the GOP would be the main beneficiary.
The ruling effectively allows party committees to spend unlimited amounts of money in coordination with their candidates. And GOP committees have been eager to put their money to use. So far, Republican party committees have spent about $112.3 million in aired coordinated spending, compared to Democrats’ $61.3 million.
That $112.3 million marks a roughly 70 percent increase over 2024 levels, when the federal limits were still in place. That year, Republican party committees spent about $65.5 million on aired coordinated spending, while Democratic committees dropped about $42.5 million.
Looking at this cycle alone, the NRSC and National Republican Congressional Committee have been active in 60 races, including 52 House contests and eight Senate races. Their Democratic counterparts, meanwhile, have spent in 56 elections – 49 House races and seven Senate races.
GOP-Aligned Outside Groups Are Bringing the Big Guns
Republican-aligned outside groups have aired nearly $750 million in ads in Senate general elections this cycle – more than twice as much as Democratic-aligned outside groups. And those GOP-aligned groups still have another $200.5 million reserved, according to AdImpact data.
Taken together, that outside money accounts for 84 percent of total Republican aired spending so far. Democratic-aligned outside groups, on the other hand, have aired about $316.9 million in Senate ads, accounting for about 50 percent of total Democratic aired spending.
That tracks with previous cycles, when Republican outside groups outgunned Democratic groups on ad spending. But also like past cycles, Democratic candidates hold an advantage in aired ad spending over Republican candidates. On the Senate side, Democratic candidates have dropped $302.8 million on aired ads, while Republican candidates have spent just $89 million. Democratic House candidates, meanwhile, lead Republicans in aired ad spending – $160.2 million to $98 million.
And because campaigns have access to lower ad rates, Democratic broadcast dollars have “generally gone further,” AdImpact notes, “offsetting some of the Republican spending advantage in most races.”
