The 2026 U.S. midterm elections are still weeks away, but the financial contest surrounding them is already operating on a scale normally associated with the final stages of a presidential campaign.
A review of federal campaign-finance data found that roughly $849 million has already been donated by a group of 25 extremely wealthy individuals and families, underscoring the growing role of personal fortunes in American electoral politics.
At the top of the list are George Soros and his family, whose political giving connected to the midterms has reached more than $103 million. Other major contributors include technology billionaire Elon Musk, hedge-fund investor Jeff Yass, Walmart heir Jim Walton, casino heiress Miriam Adelson and the Uihlein family.

Their contributions flow through campaigns, political action committees and organizations designed to support particular candidates, parties or policy priorities.
The figures illustrate how modern American elections have become increasingly intertwined with wealthy individual donors and political committees. Musk, for example, has personally contributed more than $90 million toward the 2026 midterms, with much of his money going to America PAC.
The super PAC has begun spending in congressional contests, including Senate races, after playing a major role in the 2024 election cycle. Jeff Yass has also emerged as a major donor, with roughly $92.6 million in contributions reported in the analysis.
His money has supported conservative political organizations and candidates, while the Uihleins have contributed more than $70 million. Miriam Adelson has given approximately $67.6 million, while Chris Larsen, Lyna Lam and Ripple-linked political giving collectively account for roughly $65.7 million in the cited analysis.
Artificial intelligence and cryptocurrency have also become important themes in this year’s political-finance landscape. OpenAI President Greg Brockman and his wife, Anna, have donated about $50 million, with money directed toward both an AI-focused super PAC and MAGA Inc.
Venture capitalist Ben Horowitz and his wife, Felicia, have contributed more than $45 million, including substantial funding for groups focused on technology and cryptocurrency policy. That development reflects a broader transformation in political spending.
Reuters reported in August that cryptocurrency, artificial intelligence and online betting had become major sources of corporate and billionaire spending in the 2026 congressional races. The sectors are seeking influence over issues ranging from regulation and taxation to technological development and market structure.
Yet the approximately $849 million figure should not be interpreted as the complete cost of the election. The analysis is based on federal campaign donations reported to the Federal Election Commission through September 24.
It excludes many state-level contributions and does not fully capture so-called dark-money organizations, which generally do not have to publicly identify their donors. Other analyses show the broader scale of the money already entering the 2026 cycle.
The Washington Post reported that the 50 largest individual donors had collectively contributed more than $1.7 billion by September 22. The significance of these numbers is therefore less about any single billionaire than about the structure of modern campaign finance.
Wealthy individuals can deploy enormous resources through multiple political vehicles, while campaigns compete for attention in an increasingly expensive media environment.
As November approaches, the spending is likely to remain a central feature of the midterms. The money will not determine every political outcome, but it will help shape which candidates receive advertising, organizing resources and sustained public exposure.
The expanding financial footprint provides another lens through which to understand the forces competing for influence in the 2026 elections.
