Super PACs are political action committees in the U.S. that can raise and spend unlimited amounts of money from individuals, unions, and corporations for campaign advertising. They were made possible by two 2010 judicial decisions: the Supreme Court's Citizens United v. FEC and the D.C. Circuit's Speechnow.org v. FEC. While they are barred from coordinating with or donating directly to candidates and parties, these restrictions are often seen as weak, and a 2024 FEC ruling further loosened them by allowing coordination for canvassing. The term "super PAC" was coined by reporter Eliza Newlin Carney in June 2010, and they are subject to public disclosure requirements. Many super PACs are candidate-oriented, but others focus on specific issues or legislation, making them a powerful and controversial force in modern elections.
