What it is
Super PACs, officially known as "independent-expenditure only committees," can accept unlimited contributions from individuals, corporations, unions, and other groups. Unlike traditional PACs, Super PACs cannot directly contribute to candidates or coordinate with their campaigns. Their spending must be independent, primarily through advertisements and communications that advocate for or against specific candidates, ballot measures, or political issues.
Super PACs are prominent in U.S. elections, often running high-budget advertising campaigns that can significantly influence public opinion. Their financial activity is closely watched by journalists and campaign finance reform advocates, with donors often disclosed, though some funds can be routed through "dark money" groups that do not disclose donors. Their spending can heavily shape the narrative of a race, from presidential contests to local elections.
Why it matters
Super PACs play a major role in funding political campaigns, influencing which candidates win and the policy debates that impact markets and regulations.
