How this ranking is built

Every figure above comes from lobbying disclosures filed with the Clerk of the House and the Secretary of the Senate under the Lobbying Disclosure Act. Legis1 parses each filing — registrant, client, named lobbyists, issue codes and reported amount — and aggregates them into the table.

Totals here can differ from other published tallies of the same year. Filings are amended after the fact, publishers differ on how they consolidate subsidiaries and affiliated entities, and an organization that both retains outside firms and reports its own in-house spend can be counted more than one way. Where our number differs from another source, both are usually reading the same filings under different rules.

Common questions

Which organization spent the most on lobbying in 2025?

U.S. Chamber of Commerce, at $71.2M in reported federal lobbying spend — the highest of any organization in the 2025 disclosure record.

Does this include money paid to outside lobbying firms?

Yes. An organization's reported spend covers its federal lobbying activity for the period, whether carried out by its own in-house team or by the outside firms it retains. The table shows both counts alongside the total.

Where does Legis1's lobbying organizations data come from?

From lobbying disclosures filed with the Clerk of the House and the Secretary of the Senate under the Lobbying Disclosure Act. Legis1 parses each filing — registrant, client, named lobbyists, issue codes and reported amount — and aggregates them into this table.

How current is this ranking?

It covers the full 2025 disclosure year and was captured from the filing record on June 24, 2026. Lobbying disclosures are filed quarterly, so the table changes when a quarter closes rather than continuously.

Why do these figures differ from other published rankings?

Filings are amended after the fact, publishers differ on how they consolidate subsidiaries and affiliated entities, and an organization that both retains outside firms and reports its own in-house spend can be counted more than one way. Two sources reading the same filings under different rules will not agree exactly.
