Data Sources & Methodology
All statistics are derived from Senate LDA (Lobbying Disclosure Act) filings accessed through the Senate Office of Public Records. Our database covers 2018–2025 and is updated regularly as new quarterly filings are published. For full methodology details, see our methodology page.
The Geographic Dimension of Lobbying
While Washington, D.C. is the undisputed center of lobbying activity, the clients funding these efforts come from every state. Virginia, home to many defense contractors and government services firms, consistently ranks among the top states for lobbying spending. New York's financial sector and California's tech industry also drive significant lobbying expenditures.
Explore the full state-by-state breakdown on our geographic analysis page.
The Revolving Door Effect
One of the most significant dynamics in lobbying is the "revolving door" — the movement of personnel between government positions and lobbying firms. Former members of Congress, congressional staffers, and executive branch officials command premium rates as lobbyists due to their insider knowledge and connections.
Our analysis shows that lobbyists with government experience generate significantly higher revenue for their clients. See the full analysis in our revolving door tracker.
How Lobbying Spending Compares to Government Contracts
For many companies, lobbying spending represents a tiny fraction of the government contracts and regulatory benefits they receive. The return on investment can be staggering — in some cases exceeding 20,000:1 when measured against favorable regulatory outcomes or contract awards.

Looking Ahead: 2026 Projections
With the 2026 midterm elections approaching, major regulatory battles over AI, cryptocurrency, healthcare pricing, and trade policy ongoing, lobbying spending is projected to set new records. Early 2026 filings already show year-over-year increases across nearly every sector.

Key Policy Battles Driving Spending
Several major policy fights drove the 2025 spending surge. The expansion of Medicare drug price negotiation under the Inflation Reduction Act prompted pharmaceutical companies to increase lobbying by over $40 million year-over-year. Trade policy uncertainty, including new tariff proposals and renegotiation of trade agreements, drove a 561% increase in tariff-related lobbying mentions.
The rapid advancement of AI technology created entirely new lobbying categories. Companies like OpenAI, Anthropic, Google, and Meta ramped up spending as Congress considered the first comprehensive AI regulation frameworks. AI-related lobbying mentions increased over 400% between 2023 and 2025.
Meanwhile, the cryptocurrency industry — fresh off major regulatory wins — continued investing heavily in Washington. Stablecoin legislation, DeFi oversight frameworks, and SEC enforcement actions all drove increased crypto lobbying.

Lobbying Firm Rankings 2025
The top lobbying firms saw significant revenue growth in 2025. Akin Gump Strauss Hauer & Feld retained its position as the highest-grossing firm with $58.2 million in disclosed lobbying revenue, followed by Brownstein Hyatt Farber Schreck ($47.8M) and Squire Patton Boggs ($39.1M).
Notably, boutique firms specializing in AI policy and cryptocurrency regulation saw the fastest revenue growth, with some reporting 50-80% year-over-year increases. The demand for lobbyists with technical expertise in these areas has created a talent war among K Street firms.

New Entrants and First-Time Filers
Over 2,400 new lobbying registrations were filed in 2025, the highest number since 2010. Many first-time filers came from the tech sector — AI startups, cryptocurrency exchanges, and social media companies that previously avoided Washington now see federal policy as existential to their business models.
Foreign entities also increased their lobbying presence, with registrations under the Foreign Agents Registration Act (FARA) reaching new highs. Track new entrants on our new entrants dashboard.
