Who Bought Policy in 2025

Federal lobbying is one of the more honestly disclosed corners of the political-economy record. Every organization that lobbies federal officials is required by the Lobbying Disclosure Act to file quarterly reports with the Senate Office of Public Records, listing how much was spent, who was paid, and which issues and bills were on the agenda. The data is public, the schema is stable, and the lag is short. For full-year 2025, the filings closed on January 20, 2026 and are now reportable.

What the 2025 record shows: a record-setting year. Lobbying firms collectively booked roughly $5 billion in revenue, the highest figure since quarterly reporting began in 2008. Total federal lobbying spend grew approximately 13% year-over-year. The growth was concentrated around a single bill — the One Big Beautiful Bill Act (OBBA), which became law on July 4, 2025 — and around the policy reset that accompanied the change of administration in January.

This piece is not about whether lobbying is good or bad as a category. It is about what the disclosure record shows for one calendar year, organized at the level the data itself uses: thirteen broad sectors, ranked by total spend.

1. The 2025 sector ranking

The Senate Office of Public Records publishes raw filings. OpenSecrets, a nonprofit research organization, classifies each filing into one of thirteen sectors using a hierarchical industry coding system. The figures below are drawn from that public dataset for full-year 2025.

Sector totals from OpenSecrets aggregations of Senate Office of Public Records filings, full-year 2025, downloaded January 23, 2026. Figures rounded.

2. Health is not a category, it is a juggernaut

The Health sector has led federal lobbying spend every year of the last decade. In 2025 it crossed $760 million. Inside that sector, a single industry — pharmaceuticals and health products — accounts for $451.8 million, more than the entire Defense, Construction, Labor, and Lawyers-and-Lobbyists sectors combined.

Why health spends what it spends in a given year is usually traceable to specific legislation. In 2025 the dominant driver was the One Big Beautiful Bill Act (OBBA), signed July 4, 2025, which restructured Medicaid funding and modified pharmacy benefit manager (PBM) transparency rules among many other provisions. Industry-side organizations cited OBBA more often than any other single bill in their disclosures. Blue Cross Blue Shield led with 64 OBBA mentions across its filings; the American Hospital Association recorded 48; the Pharmaceutical Research and Manufacturers of America, 25.

Two observations follow directly from the disclosure record:

• The most-lobbied issue area in 2025 was federal budget and appropriations (5,189 organizations reported activity on it). Health was second (2,610). Defense third (2,477). Tax fourth (2,415).
• The most-lobbied single bill was OBBA itself, with 2,354 organizations reporting activity on it. The second most-lobbied bill drew under 800 organizations. OBBA was, in disclosure-record terms, an outlier.

3. Top single clients tell a different story than top sectors

Sector totals can mask concentration. In 2025 the single largest spender was the U.S. Chamber of Commerce at $72.1 million, edging out the National Association of Realtors. Both organizations reduced their absolute spend from 2024, but the rest of the field grew enough to push total spending to a record. The number of organizations reporting any lobbying activity rose from 14,061 in 2024 to 15,768 in 2025, a 12% increase. The size of the registered-lobbyist workforce rose only about 5%. In other words: more clients, similar number of lobbyists. Average revenue per lobbyist rose accordingly.

4. The Trump-aligned firm phenomenon

Lobbying revenue is not the same as lobbying spend. Spend is what clients pay; revenue is what firms receive. In 2025, revenue concentration shifted noticeably toward firms with personal or political ties to the Trump administration. The clearest example: Ballard Partners, which had ranked 16th by revenue in Q3 2024, took in $25 million in Q3 2025 alone and ended the year at $59.5 million in total revenue, displacing Brownstein Hyatt as the highest-grossing lobbying firm in Washington. Brownstein Hyatt had held the top spot every year from 2021 through 2024.

This is a structural observation, not a normative one. Administration changes routinely reshuffle lobbying revenue. The 2025 reshuffle is notable for its speed and magnitude rather than its existence.

5. What the disclosure record does not show

Three categories of political-money flow sit outside the LDA filings:

• Dark money. Spending by 501(c)(4) organizations on issue advocacy is not covered by the LDA and not consistently reported elsewhere. The disclosed $5 billion is a floor, not a ceiling.
• Foreign lobbying. FARA filings (Foreign Agents Registration Act) are a separate database with different rules and lower compliance. Foreign-government-linked influence is partially counted, partially not.
• Grassroots and astroturf campaigns. Coordinated public-pressure campaigns funded by lobbying clients are generally not captured in the spend totals, even when they are explicitly designed to support a lobbying position.

What the LDA filings do show is the disclosed, on-the-record portion. That portion is roughly $5 billion. The undisclosed portion is, by definition, harder to size.

6. Methodology and scope

Source data: Senate Office of Public Records, full-year 2025 LDA filings (filings closed January 20, 2026). Sector classifications: OpenSecrets thirteen-sector hierarchy. Top-spender and top-firm rankings: OpenSecrets aggregations published January 23–29, 2026. Currency: nominal U.S. dollars. No inflation adjustment.

The figures in this piece will revise modestly over the next 6–12 months as late filings, corrections, and reclassifications are processed. OpenSecrets publishes revised totals quarterly. The bar chart and table will be updated as those revisions arrive.

7. What this piece does not argue

• This piece does not argue that lobbying is illegitimate. The right to petition the government is a structural feature of the system.
• This piece does not argue that high-spending sectors get what they want. Lobbying spend is correlated with policy attention, not with policy outcomes.
• This piece does not argue for or against any specific reform of LDA, FARA, or related disclosure rules.

The argument is narrow: the 2025 federal lobbying disclosure record is public, the totals are large, and the sector breakdown identifies where the money actually flowed.
