Political Mega-Donors
The billionaires and millionaires who fund American politics — and what they get in return.
In 2024, just 100 billionaire families contributed $2.6 billion to federal campaigns, PACs, and dark money groups — more than the combined political spending of the bottom 150 million American adults. Democracy, in theory, grants every citizen an equal voice. In practice, a handful of mega-donors drown out everyone else.
The top 10 donors alone accounted for over $1.3 billion in political spending. Their money flowed into super PACs, 501(c)(4) dark money groups, and direct contributions — a multi-layered system designed to maximize influence while minimizing accountability. Many of these donors have specific policy goals: tax cuts, deregulation, industry-friendly appointments.
PowerMap tracks 37 major political donors, totaling $2.2Bin 2024 giving. We score each donor on a "Quid Pro Quo" index — measuring the correlation between their donations and favorable policy outcomes. The average score is 61/100. 16 donors score above 70, suggesting a strong link between money given and favors received.
