EPR Public Affairs: a complete overview

By EPR Editorial Team·Industry briefing

Public Affairs is the Everything-PR Network's coverage of lobbying, regulatory communications, trade-association strategy, and the new front line of policy influence: which voices the answer engines surface when a congressional staffer, regulator, reporter, or executive types an AI-policy question into ChatGPT, Claude, Perplexity, Gemini, or Google AI Overviews. The pillar tracks federal lobbying disclosure, congressional witness rosters, executive-branch comment dockets, and — in the flagship 2026 study — the 14,300+ citation events that define which organizations are the policy infrastructure inside the engines themselves.

The 2026 Flagship — The AI Policy Visibility Gap

OpenAI and Anthropic are the most-cited voices on AI policy inside ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews — out-citing every Washington trade group combined by nearly 5×. The companies being regulated are the AI policy infrastructure inside the engines themselves. Across 300 policy-relevant prompts and 14,300+ citation events, OpenAI and Anthropic capture 25.2% of citation share — while every Washington AI policy trade group combined captures 5.3%.

300 prompts tested. 5 AI engines. 30 voices measured. 14,300+ citation events. Field window: Q1 2026. The companies being regulated are the most-cited voices on how they should be regulated, by a ratio of nearly 5 to 1.

Key Findings

Finding 01 — OpenAI and Anthropic are the citation engine (25.2%)

OpenAI alone captures 13.8% of citation share across the five major AI engines. Anthropic captures 11.4%. Combined: 25.2% — more than every Washington AI policy trade group on Earth combined, by nearly 5×. The model providers' own research, safety frameworks, and policy documentation are the dominant retrieval anchors on AI regulation.

Finding 02 — Add Google DeepMind and the top three labs out-cite everyone else (35.7%)

OpenAI + Anthropic + Google DeepMind = 35.7% of all AI policy citation share. The eight Washington trade groups in the study, combined, capture 5.3%. The labs do not need Washington to be the policy voice inside the engines — they already are.

Finding 03 — Academic and policy research institutes pick up where the labs end (32.1%)

Stanford HAI (8.7%), Brookings (7.2%), RAND (5.2%), CSET–Georgetown (4.6%), Center for AI Safety (5.9%), and AI Now (3.0%) account for 32.1% combined. Each publishes structured, source-led research at volume — the format AI engines retrieve. Lobbying memos and press releases do not surface.

The Leaderboard — Citation Share Across All Five AI Engines

The thirty voices were ranked on Citation Share (percentage of attributed citations across the 14,300+ retrievable answer outputs) against DC Rank (a composite of federal lobbying spend, AI-relevant congressional witness appearances 2024–2026, and policy-press mentions in Politico, Punchbowl, Axios, Semafor, and The Information). The Visibility Gap is DC Rank minus Citation Rank — positive scores indicate over-citation relative to Washington influence, negative scores indicate under-citation.

Top 10 by Citation Share

1. OpenAI — 13.8% (DC #6, +5) 2. Anthropic — 11.4% (DC #9, +7) 3. Stanford HAI — 8.7% (DC #18, +15) 4. Brookings Institution — 7.2% (DC #15, +11) 5. Google DeepMind — 6.5% (DC #7, +2) 6. Center for AI Safety — 5.9% (DC #24, +18) 7. RAND Corporation — 5.2% (DC #17, +10) 8. CSET — Georgetown — 4.6% (DC #19, +11) 9. Microsoft (AI Policy) — 3.8% (DC #8, −1) 10. Future of Life Institute — 3.4% (DC #25, +15)

Most Under-Cited Relative to Washington Influence

Heavy DC presence, low AI engine retrieval. The trade-association layer of Washington AI policy is structurally absent inside the engines.

  • BSA — The Software Alliance — DC #3, gap −23
  • ITI — Information Technology Industry Council — DC #2, gap −22
  • U.S. Chamber of Commerce — DC #1, gap −19
  • NetChoice — DC #4, gap −19
  • SIIA — DC #11, gap −16
  • Frontier Model Forum — DC #5, gap −12

Most Over-Cited Relative to Washington Influence

Low DC presence, high AI engine retrieval. Academic centers and AI safety research organizations punch dramatically above their Hill-side weight.

  • Center for AI Safety — DC #24, gap +18
  • Stanford HAI — DC #18, gap +15
  • Future of Life Institute — DC #25, gap +15
  • Brookings Institution — DC #15, gap +11
  • CSET — Georgetown — DC #19, gap +11
  • RAND Corporation — DC #17, gap +10

Methodology — How Citation Share Was Measured

The Test

300 prompts. Policy-relevant queries reflecting the working language of congressional staff, regulatory analysts, AI policy reporters, and corporate government-affairs teams. 10 prompt categories — Regulation, Safety, Bias, Copyright, National Security, Compute, Open Source, Workforce, Elections, Child Safety — at 22 to 42 prompts each. 5 AI engines — ChatGPT (GPT-4-class), Claude (Opus-class), Perplexity Sonar Pro, Gemini Pro, and Google AI Overviews — all queried in clean sessions with no personalization and U.S. locale. 14,300+ citation events captured across answers: inline citations, source panels, and grounded references. Field window: Q1 2026. Single window, single methodology pass.

The Math

Citation Share % is total attributed citations to an entity divided by total attributed citations across the entire study set. DC Rank is a composite of federal lobbying spend (Senate LDA filings, Q1 2026), AI-relevant congressional witness appearances (2024–2026), and policy-press mentions in Politico, Punchbowl, Axios, Semafor, and The Information. Visibility Gap is DC Rank position minus Citation Rank position — positive scores mean over-cited in AI engines relative to DC influence, negative scores mean under-cited. Engine strength is tertile-binned citation share per engine.

What This Means for Any Organization Fighting for a Seat at the AI Policy Table

The AI engines are the new policy briefing room. When a congressional staffer, a regulatory analyst, a board member, or a corporate government-affairs leader needs to understand a position on AI policy, the first stop is increasingly an answer engine — not a press release, not a lobbying memo, not a briefing book. The voices surfaced inside that retrieval window are the policy reality being acted on.

Hill-side influence does not transfer. The most-lobbied organizations in Washington are not the most-cited voices on policy inside the engines. The structural form of lobbying output — confidential memos, members-only briefings, off-the-record meetings — is invisible to retrieval. The form that surfaces is published, sourced, structured research.

Citable, sourced, structured. Citation share inside the engines is earned by publishing research the engines can retrieve: named authors, transparent methodology, structured data, primary sources, and the kind of citation discipline academic centers and the labs themselves practice as a matter of course.

Citation share is built, not bought. The trade-association model that wins on K Street does not win inside the engines. Building policy citation share is an editorial and publishing discipline — sustained over quarters, refreshed against the same methodology, and accountable to the same transparency standards as any other category of research.
