About LobbySpend
Who’s lobbying Washington?
What we do
LobbySpend turns Senate lobbying disclosures into searchable profiles of who spends what on whom — by client, firm, and issue.
We focus on U.S. federal lobbying disclosures. Every page on lobbyspend.org is built from the Senate Lobbying Disclosure Act (LDA) database, cited and linkable so readers can trace any number back to its source.
Who runs this
LobbySpend is built and maintained by the LobbyMap Team. We're a small group working on making public U.S. federal lobbying disclosures data easier for non-specialists to read. If you have a correction, a data tip, or a question about how a number was derived, the contact email below reaches us directly.
Who this is for
LobbySpend is built for journalists, policy researchers, advocacy groups, and engaged citizens.
Why this exists
Public data on U.S. federal lobbying disclosures is technically free, but practically locked behind file formats, acronyms, and paywalled dashboards. LobbySpendexists to close that gap: take the raw federal and public-sector data, and turn it into pages a normal person can read in thirty seconds.
How we work
- Primary source only. We pull from the Senate Lobbying Disclosure Act (LDA) database and cite the exact dataset and version on every page.
- No invented numbers. If a figure is not in the underlying public data, it does not appear on lobbyspend.org. We never generate synthetic statistics to fill gaps.
- Methodology, in plain English. We ingest quarterly Senate LDA filings, normalize client and registrant names to a canonical entity, index every disclosed issue code and specific lobbying activity, and roll up spend by client, firm, issue, and quarter.
- Refreshed on a schedule. Refreshed monthly; Senate LDA filings are released on a quarterly cycle, so most movement lands after each quarterly deadline.
- Corrections welcome. Readers flag issues all the time. When the source fixes a record, LobbySpend follows.
Known limitations
LDA filings disclose spend in bracket ranges (less than 10k, 10k-19k, and so on) rather than exact dollars, so dollar totals shown are estimates at the bracket midpoint. Grassroots lobbying, state-level activity, and sub-threshold spend are not captured.
Why federal lobbying disclosure deserves a public-facing home
The Lobbying Disclosure Act requires every registered lobbyist and lobbying organization in the United States to file quarterly disclosure reports with the Senate’s Lobbying Disclosure Office. The reports cover who is lobbying, on whose behalf, on which specific issues, and for how much money. The system is public, free, and comprehensive. What is missing is a navigable presentation layer that lets a citizen, journalist, or researcher trace federal lobbying activity at the industry, company, or state level without manually parsing tens of thousands of LD-2 PDFs.
LobbyMap builds that navigation layer. Every industry page rolls up the lobbying spend by sector; every state page surfaces the in-state lobbying activity; every grade page groups entities by their relative spend tier. The underlying data is the Senate’s LD-2 record; the value the site adds is the structure that makes the data accessible at scales below the firm-by-firm filing level.
How the pipeline pulls disclosure data
The pipeline pulls the quarterly LD-2 filings from the Senate Lobbying Disclosure Office’s bulk data exports on the same release cadence — within weeks of each quarter close. The filings are parsed for lobbying client, lobbying firm, specific issues, and reported spend, then aggregated into the per-industry, per-state, and per-spending-tier views.
A practical detail: filings cover federal lobbying only. State-level lobbying disclosures are run by each state’s secretary of state or ethics commission separately, on different cadences and forms. LobbyMap is the federal picture; readers researching state-level lobbying need to go to the state’s own disclosure portal.
Where lobbying disclosure has caveats
Three caveats. First, the LDA threshold for filing is relatively low (currently $14,000 per quarter), so the disclosure picture covers a substantial share of paid federal advocacy but excludes the smallest engagements. Grassroots organizing and unpaid issue advocacy are not in the disclosure system.
Second, the LD-2 reports list specific issues but at a coarse-grained level — the issue categories cover broad topics and do not capture the specific bill or rule the lobbyist was working on. For bill-level tracking, the disclosure data needs to be paired with Congressional voting records or rule-making dockets.
Third, the reported spend is the lobbying organization’s own self-report. The numbers can be subject to interpretation, particularly around whether to capitalize office overhead or pure-advocacy costs. Year-over-year changes within a single firm or client are the most reliable signal The methodology page on this site documents every dataset, every refresh cadence, and every limitation in detail so readers can trace any numeric value on the site back to the underlying federal source. We treat that traceability as a hard requirement for any data product that asks readers to make real-world decisions on its output.; cross-firm comparisons require care because of these reporting differences. Every page on the site links back to the originating federal dataset for verification; readers using the data for decisions should always cross-reference the most recent source release rather than treating any site value as the final word. Federal data products are continuously revised, and the live source is always the right reference for time-sensitive decisions.
Independence
LobbySpend is an independent publication. We are not funded, owned, or directed by any of the agencies, companies, or organizations that appear in our data. Hosting is paid for by advertising — see our Privacy Policy for details — and we do not take paid placements, sponsored rankings, or "remove-my-entry" fees.
History
LobbySpend launched in 2025 as part of a small portfolio of independent public-data sites. It has been maintained and updated continuously since.
