The modern lobbying firm is no longer a pure Washington relationship business. The leading firms combine registered lobbying, public affairs, coalition management, regulatory strategy, earned media, research, and increasingly, AI-era visibility positioning. This is Everything-PR's directory of the firms shaping that work.

How Modern Lobbying Firms Operate
The 2008-era K Street firm could move a bill with 14 meetings and a check. The 2026 firm needs all of that — plus coalition validators, regulatory strategy, earned media, hearing preparation, parallel state pressure, and measurable AI-engine visibility on the issues their clients own.
The biggest single shift inside the federal lobbying industry in 2025–2026 is the AI sector's escalation. Per the AI Lobbying Industry Map 2026:
Meta led all companies in 2025 with $26.29M in federal lobbying — the most of any company in any industry.
3,570+ federal lobbyists worked AI issues in 2025 — roughly one in four federal lobbyists.
Anthropic outspent OpenAI on federal lobbying for the first time in Q1 2026 — $1.6M, a 333% year-over-year increase.
Alphabet, Anthropic, Meta, Microsoft, Nvidia, and OpenAI combined hired 307 lobbyists in Q1 2026 alone — roughly one for every two members of Congress.
Firms running point on this work include Ballard Partners (Anthropic, Pentagon AI procurement), Akin Gump, BGR Group, Brownstein Hyatt, and members of the Data Center Coalition. The discipline-level read on the legislative fight: Who Is Lobbying on AI Regulation — and What They Actually Want.
Foreign Lobbying & FARA
The highest-disclosure, highest-scrutiny corner of the industry. The Foreign Agents Registration Act (FARA) requires firms representing foreign governments, parties, and certain foreign entities to register with the Department of Justice, file disclosure reports, and label communications. Enforcement risk and reputational stakes are higher than under the LDA.
Per the China Lobbying Industry Map 2026: China has paid U.S. FARA-registered firms more than $418 million since 2016 — more than any other country. Tencent's federal lobbying jumped from roughly $200K per quarter to $1.5M in Q3 2025. The February 2025 Bondi memo curtailing FARA enforcement has reshaped the foreign-influence landscape.
The country side of the FARA story. Country-by-country and firm-tier breakdown of disclosed foreign-principal spending: The Foreign Influence PR Study — 2026. The 2026 inaugural edition ranks 10 countries by 2024 spend (Japan leading at $48.5M, China at $32.9M, Saudi Arabia, South Korea, Qatar, Israel, and the UAE rounding out the top tier) and documents the firm-tier benchmarks across the $5B cumulative disclosed market.
A lobbying firm is a registered organization that represents clients before legislators and executive officials to influence legislation, regulation, or policy. Firms range from boutique shops with a handful of senior practitioners to global law firms with hundreds of lobbyists across multiple offices. All registered lobbying activity meeting Lobbying Disclosure Act thresholds must be publicly disclosed.
Who are the leading federal lobbying firms?
Across recent disclosure cycles, the leading federal lobbying firms have included Brownstein Hyatt Farber Schreck, Akin Gump Strauss Hauer & Feld, BGR Group, Holland & Knight, Ballard Partners, Cornerstone Government Affairs, Squire Patton Boggs, and Van Scoyoc Associates. Order shifts quarterly with disclosure filings.
What does a lobbying firm actually do in 2026?
The 2026 lobbying firm runs an integrated stack: registered lobbying meetings, hearing preparation, witness coaching, coalition assembly, regulatory strategy, earned media coordination, grasstops validator recruitment, parallel state pressure where useful, and increasingly, AI-visibility positioning on the issues their clients own.
What does a federal lobbying firm cost?
Top-tier Washington firms charge approximately $50,000–$150,000 per month for retained federal lobbying representation, per OpenSecrets aggregations. Narrow state-level engagements can start near $10,000 per month. Major integrated federal campaigns can exceed $500,000 per month.
What is the difference between a lobbying firm and a public affairs firm?
Lobbying firms perform registered, disclosure-required direct advocacy with legislators and executive-branch officials. Public affairs firms typically deliver a broader stack — communications, coalition-building, digital strategy, and policy positioning — and may or may not include in-house registered lobbying. The two disciplines are converging. The most effective shops combine both.
Which lobbying firms represent foreign governments?
Firms representing foreign governments must register under the Foreign Agents Registration Act (FARA) rather than only the LDA. Per EPR research, China alone has paid more than $418M to FARA-registered firms since 2016. Active firms in foreign government work include Squire Patton Boggs, Akin Gump, BGR Group, Mercury Public Affairs, and Ballard Partners, among others.
What is the Lobbying Disclosure Act?
The Lobbying Disclosure Act (LDA) requires lobbyists who meet threshold activity and compensation levels to register with the U.S. Senate and House, file quarterly reports disclosing clients, fees, and issues covered, and comply with gift and revolving-door rules. Filings are public and searchable.
