The federal lobbying industry hit $6.0 billion in reported income in 2025, the highest single-year total in our dataset. Here's everything you need to know about who's lobbying, how much they're spending, and where the money goes.
Key Statistics at a Glance
How Much Is Spent on Lobbying Each Year?
Federal lobbying spending has grown significantly over the past eight years:
| Year | Total Income | Filings | YoY Change |
|---|---|---|---|
| 2025 | $6.00B | 107,600 | +15.6% |
| 2024 | $1.98B | 82,249 | −11.5% |
| 2023 | $2.24B | 95,236 | +9.4% |

The 2025 spike is notable — a 36% increase over 2024, driven largely by tariff-related lobbying, AI regulation debates, and continued healthcare policy fights.
Who Spends the Most on Lobbying?
The top lobbying spenders include a mix of trade associations, pharmaceutical companies, tech giants, and defense contractors. See our full client rankings for the complete list.
Key industries by lobbying spend:
- Healthcare & Pharmaceuticals — Consistently the largest lobbying sector, driven by drug pricing debates, Medicare/Medicaid policy, and FDA regulation
- Technology — Rapidly growing, fueled by AI regulation, data privacy, antitrust, and content moderation debates
- Defense & Security — Steady spending tied to defense authorization and procurement
- Finance & Insurance — Banking regulation, fintech, cryptocurrency policy
- Energy & Environment — Climate policy, oil/gas regulation, renewable energy incentives
The Revolving Door
One of the most significant dynamics in federal lobbying is the "revolving door" — former government officials who become lobbyists. Our data identifies 5,000 lobbyists with prior government positions, including former members of Congress, agency heads, White House staff, and military officials.
See our full Revolving Door analysis and the investigation exposing the most egregious transitions.
Foreign Lobbying
Foreign governments and entities also lobby the U.S. Congress, primarily through American lobbying firms. Our data tracks 1,000 foreign entities involved in lobbying, from allied nations like the UK and Canada to adversarial governments. See our foreign lobbying tracker.
What Issues Get Lobbied Most?
The Lobbying Disclosure Act requires filers to categorize their lobbying by issue area. The top issue categories by spending include:
- Health Issues (HCR) — Drug pricing, Medicare, Medicaid, FDA approvals
- Budget/Appropriations (BUD) — Government spending priorities
- Taxation (TAX) — Corporate tax policy, individual tax reform
- Trade (TRD) — Tariffs, trade agreements, sanctions
- Defense (DEF) — Military contracts, weapons systems, veterans affairs
- Energy (ENG) — Oil/gas, renewables, climate policy
- Technology (CPT) — AI, data privacy, telecommunications
Explore all 79 issue categories with spending data.
How Does Lobbying Work?
Under the Lobbying Disclosure Act of 1995 (amended 2007), any individual or organization that spends more than $14,000 per quarter on lobbying activities must register with the Senate and file quarterly disclosure reports. These reports include:
- Income received (for lobbying firms) or expenses (for in-house lobbying)
- Names of specific lobbyists involved
- Issue areas lobbied
- Specific bills or executive branch actions targeted
- Whether any lobbyists held prior government positions
- Any foreign entity involvement

The Revolving Door Premium
One of the most significant statistics in our dataset: lobbying firms that employ former government officials charge an average of 369% more than firms without revolving-door lobbyists. This premium reflects the market value of insider knowledge, personal relationships, and institutional familiarity that former officials bring to lobbying.
Among the 5,000+ former government officials now registered as lobbyists, former members of Congress command the highest premiums. Former committee chairs and ranking members are especially valuable, as their expertise and relationships center on the most consequential policy areas. See our full revolving door analysis.
Lobbying Growth by Sector (2018-2025)
Different industries have grown their lobbying presence at very different rates:
- Technology: +340% growth — driven by antitrust, AI, and privacy regulation
- Cryptocurrency: From near-zero to millions annually — the fastest new entrant
- Education: +9%/year — student loans, Title IX, federal funding battles
- Transportation: +7%/year — infrastructure, EVs, FAA reauthorization
- Healthcare: +8%/year — consistently the largest sector at $4.4B+ total
- Defense: +5%/year — steady growth tied to increasing defense budgets
- Telecom: +2%/year — the slowest-growing major sector

The Tariff Lobbying Explosion
One of the most dramatic trends in 2025 was the explosion of tariff-related lobbying. As new trade policies introduced sweeping tariffs on imports from China, the EU, and other trading partners, industries scrambled to secure exemptions. Our analysis shows a 561% increase in trade-related lobbying filings between 2023 and 2025.
Companies that had never lobbied before suddenly registered lobbyists, and existing lobbying operations expanded dramatically. The retail, automotive, and manufacturing sectors were particularly active, with companies like Walmart, Toyota, and Caterpillar significantly increasing their DC presence. See our full tariff lobbying investigation.
AI Regulation: The Newest Lobbying Frontier
Artificial intelligence has emerged as one of the fastest-growing lobbying issues. AI-related mentions in lobbying filings surged over 400% between 2022 and 2025, as tech companies, defense contractors, healthcare organizations, and financial institutions all rushed to shape emerging AI policy.
The debate spans multiple issue areas — from data privacy and intellectual property to national security and workforce displacement. Companies like OpenAI, Anthropic, Google, Microsoft, and Meta are all actively lobbying on AI regulation, often with conflicting positions on how strict rules should be. Explore the momentum tracker to see which AI-related issues are surging right now.
