Dark Money

Dark money refers to political spending by groups that don’t have to disclose where their funding comes from, even as they run ads and campaigns meant to influence elections. It flows through nonprofit organizations that are allowed to keep donors secret, letting people and corporations shape political debate without their names ever showing up on a public filing.

How the money moves. Groups organized under certain tax-exempt categories can accept unlimited contributions and spend heavily on political messaging as long as election activity isn’t their primary purpose. Because the disclosure rules governing these groups differ from the ones that apply to candidates and parties, the public often has no way to trace who is actually paying for a given ad campaign. This sits alongside the broader system of contribution limits and reporting requirements that govern more traditional campaign giving, explained in Hard Money vs. Soft Money: How Campaign Finance Rules Shape American Elections.

Why it matters. Supporters of the current rules argue that anonymous giving protects donors from harassment and preserves a form of political speech. Critics counter that voters can’t fairly judge a political message without knowing who paid for it, and that hidden money makes it easier for narrow interests to influence officials without accountability. That disagreement over disclosure versus privacy runs through nearly every debate about reforming how election spending gets reported.
