Top 50 donors give $2.77 billion

The 50 largest donors and organizations have injected $2.77 billion into the 2026 midterm election cycle. AdImpact projects total political advertising spending will hit $11.6 billion by election day. That figure exceeds the record set during the 2024 presidential race.

Federal Election Commission data shows a sharp split in funding sources. Republican-aligned contributors have provided $1.67 billion, or 60 percent of the total. Democratic-aligned groups have given $832 million, accounting for 30 percent. The remaining $264 million, or 10 percent, comes from bipartisan and special interest sources, including sports betting and cryptocurrency firms.

Individual donation limits for federal candidates stand at $3,500 per election. However, wealthy donors bypass these caps by giving to super political action committees. These groups can accept unlimited sums as long as they do not coordinate spending directly with candidates. Elon Musk, the head of Tesla and SpaceX, leads all individual donors with a contribution of $446 million.

Elizabeth and Richard Uihlein, founders of the shipping supplies company Uline, rank second among individuals with $150 million. Jeff and Janine Yass, whose husband cofounded Susquehanna International Group, are third with $110 million. All three have directed their funds toward Republican-aligned organizations.

On the Democratic side, billionaire investor George Soros has given $102 million. Former New York City mayor Mike Bloomberg has contributed $84 million. LinkedIn cofounder Reid Hoffman and his wife, Michelle Yee, have donated $41 million. Four individuals in total have each provided more than $100 million to the cycle.

Organizational giving also drives the totals. One Nation, a nonprofit linked to Senate Republican leadership, has given $133 million. American Action Network, tied to House Republican leadership, has contributed $64.3 million. On the Democratic side, Majority Forward and House Majority Forward have given $102 million and $93.7 million, respectively.

Cryptocurrency firms have become major players in the funding landscape. Coinbase has donated $57.8 million, Ripple $49.6 million, and Foris DAX $39 million. The industrial conglomerate Koch has given $46.8 million, while sports betting firm DraftKings has contributed $40.4 million. Lawrence Lessig, a Harvard Law School professor, argues that the concentration of these large donors poses a greater threat to democracy than the overall spending volume.
