What we are
DonorAlpha is Campaign Finance Intelligence for the 2026 midterms. It shows who’s spending in every House and Senate race, who’s paying for it, and how the groups connect.
Every page is free to read, the figures are updated every night, and each page shows the day it was last updated.
It’s also the public face of a bigger campaign and advertiser finance intelligence platform. Think of this as the showroom, minus the salespeople.
What you’ll find
- Races. The outside money in every House and Senate race, supporting and opposing each candidate by name, week by week. Open your race
- Rankings. The super PACs that spent the most, who gave to them, the biggest online ad spenders and the people writing the biggest checks. See the rankings
- Groups. Committees, nonprofits and companies that share an office, an officer or a sponsor, seen as one, with the money that moves between them. Search for one
- Plain English. Campaign finance has its own language. We translate. The glossary
How we keep it straight
- Every figure is added up from what the committees and the ad libraries reported themselves.
- A connection is drawn only when the filings themselves declare it, or when multiple independent records corroborate it. Anything short of that is labelled “Possible link”.
- Every identity decision is recorded with its reasons, and every merge can be undone.
- Results appear as soon as they’re reported, and the final count replaces them when it lands.
