Just 50 American families have funneled more than $600 million into the 2024 elections in donations to political parties, PACs and super PACs, a new report has found a staggering figure that underscores the disproportionate influence the wealthy will wield on the outcome of Novembers elections.

The report, from the progressive nonprofit Americans for Tax Fairness (ATF), tracked the top 50 families or individuals, all worth billions, who have pumped the most money into the political system as of early May.

These 50 billionaire families alone have the political-spending capacity of over 6 million ordinary American families, wrote the authors, senior ATF associate Zachary Tashman and senior writer William Rice. They based the comparison on the average net worth of the American family and the average net worth of the 50 families in the report, who have a combined net worth of more than $1 trillion.

More than two-thirds, or 69%, of their donations flowed to Republican candidates or causes, including the super PAC supporting former President Donald Trumps reelection campaign, and Americans for Prosperity Action, a super PAC affiliated with the Koch family that supports conservative candidates. Only 23% went to groups supporting Democrats, and the remainder did not have a clear partisan affiliation.

That pronounced GOP tilt is a sign that the political spending of billionaire families is largely an investment in preserving familial wealth and power, the authors argued, noting that many Democrats campaigned on raising corporate income taxes and taxes on the wealthiest 1%, while Republican policies further insulate major fortunes from taxation.
