Super PACs channel $2.77 billion from top donors for 2026 midterms

The 2026 United States midterm elections are shaping up to be the most expensive in the nation's history, driven by record inflows from wealthy individuals and corporations. AdImpact projects that political advertising spending will reach $11.6 billion, surpassing the cost of the 2024 presidential race.

Federal Election Commission data indicates that the fifty largest donors and organizations have contributed a combined $2.77 billion so far this cycle. Republican-aligned contributors account for $1.67 billion, which is roughly 60 percent of the total. This amount is double the $832 million, or 30 percent, contributed by Democratic-aligned donors. The remaining $264 million comes from bipartisan and special interest groups, including those supporting sports betting and cryptocurrency.

Elon Musk, the chief executive of Tesla and SpaceX, is the single largest individual donor with $446 million. He is followed by Elizabeth and Richard Uihlein, founders of the shipping supplies company Uline, who gave $150 million, and Jeff and Janine Yass, cofounders of the trading firm Susquehanna International Group, who contributed $110 million. All three top individual donors have directed their funds to Republican-aligned groups. On the Democratic side, George Soros leads with $102 million, followed by former New York City mayor Mike Bloomberg with $84 million, and LinkedIn cofounder Reid Hoffman and his wife Michelle Yee with $41 million.

Much of this wealth bypasses standard contribution limits through super political action committees. These groups can raise and spend unlimited sums to support or oppose candidates, provided they do not coordinate spending directly with campaigns. Super PACs emerged after 2010 court rulings allowed for independent expenditure. While they must report donors to the FEC, some major contributors operate as nonprofit groups that do not disclose their sources, a practice often called dark money. Lawrence Lessig, a professor at Harvard Law School, argues this opacity hides the money from voters rather than politicians. He stated, "It's not dark to the politicians. It's dark to us."

Organizational giving is also concentrated among political nonprofits and industry leaders. One Nation, a nonprofit aligned with Senate Republican leadership, donated $133 million. American Action Network, linked to House Republican leadership, gave $64.3 million. On the Democratic side, Majority Forward contributed $102 million, and House Majority Forward gave $93.7 million. Industry interests also play a large role, with Coinbase giving $57.8 million, Ripple giving $49.6 million, and the Koch conglomerate giving $46.8 million.

Four individual donors have each given more than $100 million, a concentration that Lessig identifies as the primary concern. He noted that the issue is not the total spending but the limited number of high-value contributors. "If you don't have $100 million to put on the table, you're not going to matter in the way that we think that people ought to matter in a democracy," Lessig said.

These contributions flow into networks of organizations before being spent on advertising and other election activities. The November 3 vote will determine which party controls Congress, with the heavy financial backing of both sides signaling a competitive environment. The FEC data reflects contributions made through the 2025 and 2026 election cycles, where individuals can donate up to $3,500 per election to federal candidates, though super PACs allow for much larger transfers from the same individuals.
