Top Donors

Who are the top Dark Money Donors?

While political nonprofits are growing in popularity because they are not required to publicly reveal who their contributors are, they must disclose contributions that they themselves make.

By sifting through thousands of 990 tax forms, the Center for Responsive Politics has come up with this list of top donor organizations to politically active 501(c) nonprofits and their affiliates. Despite this effort, the sources of much of the money flowing to politically active nonprofits remain unknown.
