2026 US Midterms Projected as Most Expensive in History

The 2026 US midterm elections are projected to be the most expensive in history, with spending on political advertising alone expected to reach $11.6 billion. Data from the Federal Election Commission shows that the 50 largest donors have contributed a combined $2.77 billion to the cycle.

Elon Musk is the largest individual donor, contributing $446 million to Republican-aligned groups. Republican-aligned contributors account for 60% of the top donor pool at $1.67 billion, while Democratic-aligned contributors provide $832 million, or 30%. Other top Republican donors include Elizabeth and Richard Uihlein and Jeff and Janine Yass, while George Soros, Mike Bloomberg, and Reid Hoffman and Michelle Yee lead Democratic contributions.

Funding is heavily directed toward super PACs and nonprofit organizations. One Nation is the largest Republican-aligned organizational contributor with $133 million, and Majority Forward is the largest Democratic-aligned organizational contributor with $102 million. Cryptocurrency firms, including Coinbase and Ripple, have also provided significant funding, with Coinbase contributing $57.8 million. Some nonprofit groups continue to utilize dark money to obscure the identities of original donors.
