Public information should be easy to find and understand.

Transparency laws and programs are meant to help people see what their government is doing. Yet outdated software, incompatible files and a lack of awareness can leave public information out of reach.

Dark Money Map brings that information into view. Our goal is to help everyday people find public records, understand their connections and check the original sources, starting with California.

Why we built Dark Money Map

Explore the map.

Every record on the map is a public filing: a committee, a donor, a lobbying payment, a bill position. Pick a name and follow its connections one step at a time. Each connection keeps its amount, its date and a link back to the original source.
