Billionaires pour record $2 billion into US midterm elections, raising concerns over political influence

NEW YORK (Common Dreams) – Some of the wealthiest Americans have channelled unprecedented amounts of money into the 2026 midterm elections, with the 20 largest donors alone contributing a combined $2 billion to federal races this election cycle, according to a New York Times analysis published Sunday.

Far-right billionaire Elon Musk has emerged as the largest individual financier by a considerable margin, spending nearly $450 million in support of Republican candidates.

Republican-aligned donors account for the five largest contributors to this year’s midterm campaigns, highlighting the growing financial advantage of conservative interests in electoral politics.

Other major contributors include industrialists Richard and Elizabeth Uihlein, who have donated $150 million to Republican candidates; the leading Republican Senate super PAC, One Nation, which has spent $138 million; venture capitalists Marc Andreessen and Ben Horowitz, whose contributions total $116 million; and hedge fund investor Jeff Yass, who has provided $110 million.

On the Democratic side, the largest contributors include Majority Forward, the party’s principal Senate-aligned super PAC, which has spent $104 million, and George and Alexander Soros, who have collectively donated $103 million.

The findings are broadly consistent with a separate analysis released last week by the Brennan Center for Justice, which found that the 40 largest individual donors had spent a combined $2.4 billion on the 2026 elections by mid-October.

The Brennan Center described the figure as the highest amount ever recorded for a midterm election since the Supreme Court’s landmark 2010 Citizens United v. Federal Election Commission ruling opened the door to virtually unlimited independent political spending by corporations, wealthy individuals and outside groups.

The analysis also highlighted a sharp increase in the financial power of major political donors over the past decade. The 40 largest contributors had collectively spent eight times more by mid-October than the equivalent group during the 2014 midterm elections, even after adjusting for inflation.

The minimum contribution required to enter the top 40 has also risen tenfold over the same period, reaching $25 million.

The political orientation of major donors has also undergone a significant shift. While wealthy contributors previously tended to favour Democratic candidates, Republican-aligned donors now contribute more than three times as much as their reliably Democratic counterparts, according to the Brennan Center.

The analysis further found that labour unions, which previously featured among the country’s largest political contributors, have disappeared from the top 40 list, replaced in part by wealthy backers from the cryptocurrency industry.

Ian Vandewalker, senior counsel at the Brennan Center and co-author of the report, told The Guardian that the growing dependence on wealthy individual contributors has made it easier for politicians to prioritise the interests of major donors over those of ordinary voters.

He argued that the concentration of financial influence undermines the democratic principle of political equality, in which every citizen should have an equal voice through their vote.

Economist Paul Krugman raised similar concerns in a commentary published Monday, describing the 2026 midterms as a contest over the growing influence of oligarchic wealth in American politics.

Krugman attributed much of the problem to the Supreme Court’s Citizens United ruling but also argued that decades of economic policies favouring the wealthiest Americans had helped create the conditions for such concentrated political power.

He warned that the growing wealth of a small group of individuals had given them the means to exercise extraordinary influence over the US government, describing the midterm elections as a test of whether they would be allowed to maintain that influence.
