The 2026 US midterm elections are on track to shatter financial records, with spending on political advertising alone projected to reach $11.6bn, according to Al Jazeera citing data from the ad-tracking firm AdImpact. Behind these staggering figures are wealthy donors, political nonprofits, and businesses striving to influence Washington’s political agenda ahead of the November 3 vote.

According to Al Jazeera's analysis of Federal Election Commission data, the 50 largest donors and organisations have collectively contributed $2.77bn during the current election cycle. Republican-aligned contributors lead this spending, accounting for $1.67bn or roughly 60 percent of the total, while Democratic-aligned contributors have provided $832m, representing 30 percent. An additional $264m, or 10 percent, came from bipartisan or special interest groups, including those supporting cryptocurrency and sports betting.

While individuals face a legal limit of $3,500 per election when donating directly to a federal candidate's campaign, top contributors have given hundreds of millions through super political action committees, or super PACs. Al Jazeera reported that these groups can accept unlimited sums for advertising to support or oppose candidates, provided they do not coordinate directly with the campaigns.

Background

Super PACs were established in 2010 following two court rulings that permitted unlimited independent spending on elections. Al Jazeera noted that while these groups must report their donors to the Federal Election Commission, certain major nonprofit contributors—such as One Nation and Majority Forward—are not required to disclose their individual donors, a practice commonly referred to as “dark money”.

Discussing transparency in campaign finance on Al Jazeera’s Let’s Focus, Harvard Law School professor and campaign finance reform advocate Lawrence Lessig argued that the funding sources remain hidden only from the general electorate. “It’s not dark to the politicians. It’s dark to us,” Lessig told Josh Rushing, as reported by Al Jazeera.
