Twenty-four prompts. Two engines. Five wires. The first independent measurement of how AI engines actually cite the press release distribution networks American comms teams pay for.
By EPR Editorial Team. June 2026.
The wire spend hierarchy and the AI citation hierarchy do not match.
Companies paying $2,000 to $3,000 per release on PR Newswire and Business Wire often get zero citation surface inside Claude and Google AI Overviews. Companies paying $400 to $800 per release on GlobeNewswire, Newsfile, and ACCESS Newswire often get direct domain citation in the engines' source set.
The deeper finding sits underneath the wire-vs-wire question. Editorial rewrites beat primary-source releases in AI engine retrieval. When CNBC, Variety, Quartz, MacRumors, 9to5Mac, or BioSpace process a wire release into editorial coverage, the engines cite the editorial layer — not the wire. When Morningstar, Stocktitan, QuiverQuant, or FinancialContent syndicate the same release with the wire brand preserved in the URL or body text, the engines cite the wire's attribution. The press release is the input. The editorial rewrite is what the AI engines surface as the answer.
The implication is bigger than wire services. It applies to investor relations announcements, government press offices, earnings releases, corporate newsrooms, and the entire primary-source-to-AI-engine pipeline. Owning the editorial rewrite is now more valuable than owning the primary source release. The wire study is the proof.
Five wires. Five verticals. GlobeNewswire takes 31.3% Citation Share. Business Wire and PR Newswire tie at the next tier — 18.8% and 16.7%. Newsfile and ACCESS Newswire each take 12.5%, but both win their target vertical outright. Five of 24 prompts (21%) returned zero wire surface across every engine and every wire — every one of those a mega-cap consumer tech brand (Apple, Meta, Microsoft, Nvidia), a regulated mid-cap with heavy SEC reporting (AST SpaceMobile), or a generic category-level question.
This is the first independent study to measure it.
Five wires. PR Newswire (Cision), Business Wire (Berkshire Hathaway), GlobeNewswire (Notified), TMX Newsfile (TMX Group), and ACCESS Newswire (Issuer Direct Corp, NYSE American: ACCS).
Five verticals. Tech earnings, biotech, consumer/product launches, mergers and acquisitions, junior mining.
Twenty-four prompts. Buyer-research-style queries — the kind a journalist, analyst, or comms team would actually type into an AI engine. Examples: "What did Meta report for Q1 2026 earnings?" "What's the latest from Apogee Therapeutics on APG777?" "Who is acquiring Talkspace?" "Dakota Gold Richmond Hill drilling results."
Two engines tested directly. Claude (Anthropic) and Google AI Overviews / Google Search. Direct retrieval testing across all 24 prompts.
Three engines analyzed structurally. ChatGPT, Gemini, and Perplexity — covered in Appendix A. Retrieval-architecture analysis only, not direct testing. Full direct testing across all five engines is the Phase 2 expansion.
Scoring rubric. Per prompt, per engine: 2 points if the wire's domain appears directly in the engine's source surface. 1 point if the wire's content surfaces via a downstream syndication carrier with brand attribution preserved. 0 if not detectable. Citation Share = total points / maximum possible points.
The most important finding rewrites the question every CCO has been asking. The question is not "which wire is best?" — it is "which wire owns my vertical?"
| Vertical | Winner | Runner-up | Absent |
|---|---|---|---|
| Biotech (small/mid-cap) | GlobeNewswire | — | PR Newswire, Business Wire, Newsfile, ACCESS Newswire |
| Mid-cap medtech / B2B SaaS | Business Wire | — | PR Newswire, GlobeNewswire, Newsfile, ACCESS Newswire |
| Large-cap B2B (cybersecurity, banks) | PR Newswire | Business Wire (deal phase 2) | GlobeNewswire, Newsfile, ACCESS Newswire |
| Junior mining (US-listed micro-cap) | Newsfile | GlobeNewswire, ACCESS Newswire | PR Newswire, Business Wire |
| Junior mining (Canadian-listed) | ACCESS Newswire | GlobeNewswire, Newsfile | PR Newswire, Business Wire |
| Mega-cap consumer tech | None | None | All five |
GlobeNewswire posts the highest aggregate Citation Share — but only because biotech and regional bank M&A appeared in eight of the 24 prompts and the small-wire vertical (junior mining) is shared three ways. No wire dominates outside its lane. None.
For a CCO this changes the buying question. PR Newswire selling reach into biotech is irrelevant — GlobeNewswire already owns the biotech editorial-syndication graph that the AI engines index. Business Wire selling reach into junior mining is irrelevant — Newsfile and ACCESS Newswire own the junior mining trade-press graph. Wire choice should follow vertical, not budget tier.
Five prompts returned zero wire surface. Meta. Microsoft. Apple. Nvidia. AST SpaceMobile.
The first four are mega-cap consumer tech. Each uses a major wire for distribution. Meta and Microsoft distribute earnings via PR Newswire. Nvidia and AST SpaceMobile distribute via Business Wire. Apple distributes via its own newsroom. None of those wire releases surfaces in AI engine retrieval.
What surfaces instead: CNBC, Variety, Quartz, 9to5Mac, MacRumors, Futurum, S&P Global, TIKR, Tickeron, SEC EDGAR filings, and the company investor relations page. The wire payload is upstream of every one of those sources — the editorial layer rewrites the news, the IR page hosts the release, the SEC 8-K duplicates it. The engines pick the rewrites.
The math gets uncomfortable. A 1,000-word national PR Newswire release with one image runs $1,500 to $3,000 once membership and add-ons are calculated, per Pressonify's 2026 pricing comparison. A Business Wire release of equivalent size and reach runs $2,210 minimum, per Prezly's pricing analysis. Apple, Meta, Microsoft, and Nvidia each issue 30 to 60 material releases per year. The line item is meaningful. The AI visibility return on that spend is zero.
This does not mean the wire spend is wasted. Regulation FD compliance, AP and Reuters wire dissemination, and investor wire requirements are all real. But for AI engine visibility specifically, the spend is a sunk cost. The category structure determines the outcome, not the wire.
The same effect appears in a different vertical for a different reason. AST SpaceMobile is a $9 billion mid-cap satellite company with active SEC reporting and heavy specialist trade coverage from SpaceNews, SatelliteToday, and Advanced Television. The Business Wire release is upstream of all of it. The engines retrieve the SEC 8-K and the trade pubs. The wire vanishes. Heavy SEC filings plus dense specialist trade press also creates a wire dead zone — not just mega-cap.
Some downstream carriers preserve wire brand attribution into AI engine retrieval. Others bury it. The carrier graph matters more than the wire's nominal distribution network.
Carriers that preserve wire attribution, observed directly in this audit:
/news/business-wire/, /news/pr-newswire/, /news/accesswire/bizwire-2026-..., newsfile-2026-.../tmt-newswire/globenewswire//Newsfile/Carriers that bury attribution:
The implication is buyable infrastructure for any wire. A wire that aggressively syndicates into brand-preserving carriers (Morningstar, Stocktitan, FinancialContent, QuiverQuant) buys itself AI visibility independent of the engine's primary retrieval choice. ACCESS Newswire's apparent strength in junior mining is downstream of its Morningstar partnership preserving the "ACCESS Newswire" brand in every URL. Newsfile's strength is downstream of StreetInsider, FinancialContent, and Junior Mining Network all preserving the "Newsfile Corp." brand.
This is also a measurable diagnostic — and a commercial product. A Citation Audit can map which carriers preserve attribution for any given client's wire and identify where the syndication graph leaks.
Same deal, different wires across announcement stages. Observed directly:
Implication for M&A practitioners. Consistency of wire across the deal lifecycle is a measurable gap. A deal that runs PR Newswire for the announcement and GlobeNewswire for shareholder approval fragments its citation profile inside the engines. The retrieval surface for "What is the status of the [deal name] acquisition?" gets split across both wires' attribution graphs — and the engines weight the most recent release. The first wire's announcement investment gets diluted by the second wire's update.
This is solvable. A locked single-wire strategy across deal phases is a simple Citation Share optimization. Most comms teams do not currently treat wire choice as a deal-lifecycle decision.
The expensive wires sell to the brands the AI engines won't cite. The cheap wires sell to the brands the AI engines do cite.
Current 2026 wire pricing — verified from primary sources:
| Wire | Base 400-word national | Membership | Realistic full cost (1,000 words + image) | Owner |
|---|---|---|---|---|
| PR Newswire | $850 | $195/yr | $1,500–$3,000+ | Cision |
| Business Wire | $760 | None | ~$2,210+ | Berkshire Hathaway |
| GlobeNewswire | ~$350 | None | $600–$900 domestic; $1,500+ international | Notified |
| TMX Newsfile | Quote-based | None | $400–$800 (junior mining specialist tier) | TMX Group |
| ACCESS Newswire | Starts $415 | None | $175–$1,095 range; 5-pack $660 each | Issuer Direct Corp (NYSE: ACCS) |
PR Newswire and Business Wire are the most expensive. They also have the highest dead zone rate — used by the brands the AI engines will not surface. GlobeNewswire is the cheapest of the Big Three and the highest in Citation Share. Newsfile and ACCESS Newswire are the cheapest of the five and the only two wires that own a vertical outright.
The conclusion is sharp. AI visibility is not for sale at the high end of the wire price tier. The premium wires deliver SEC compliance, AP and Reuters reach, and tier-one financial wire credibility — real value, but not AI retrieval value. The cheap wires deliver retrieval surface inside the engines because their client base sits in verticals where editorial does not crowd the wire out.
While PR Newswire and Business Wire continue selling 2010-era value propositions — reach, AP, Reuters, SEC compliance — the smaller wires have publicly repositioned around AI visibility.
TMX Newsfile published primary research on AI crawler activity. Per their analysis: mining and energy press releases generated higher levels of AI activity per release than Technology & Innovation announcements. They studied AI crawler behavior across roughly 120 releases over a 72-hour window. Their study confirms — from the wire's own data — what this audit observed from the retrieval side.
ACCESS Newswire (NYSE American: ACCS) launched ACCESS Insights & Analytics, an AI-powered analytics platform that scores press releases across eight AI metrics and predicts LLM discoverability. The publicly traded parent (Issuer Direct Corp) carries a Strong Buy analyst rating and a 12-month price target of $14 on the bet that AI visibility tooling becomes the wire industry's next product category.
GlobeNewswire (Notified) positions its 2026 pricing pages around AI-ready metadata as a built-in differentiator versus PR Newswire.
PR Newswire (Cision) and Business Wire (Berkshire Hathaway) are quieter on the AI visibility positioning. They continue to lead on AP and Reuters credibility and SEC EDGAR compliance — both real, both valuable, neither solving for AI retrieval.
The small wires are betting their future on the question this study measures. The big wires are betting on the value propositions that built their networks twenty years ago. The audit data suggests the small wires' bet is the right one.
Honesty requires this caveat. Wire dominance correlates with client tier — which means wire choice is partially an artifact of company size and vertical, not pure wire network quality.
Junior miners use Newsfile and ACCESS Newswire because those wires are cheap and dominate the junior mining trade-press syndication graph. Mid-cap biotech uses GlobeNewswire because it is cheap and dominates the biotech editorial graph. Mid-cap medtech and B2B SaaS use Business Wire because the brand carries weight with the syndication carriers that index those verticals. Mega-cap consumer tech uses PR Newswire and Business Wire for SEC and AP and Reuters distribution — and gets eaten by editorial because that is what mega-cap consumer tech always gets.
This does not invalidate the Citation Share findings. Companies experience the wire choice they make — the observed retrieval matters regardless of cause. But a controlled experiment — same release distributed via different wires — would isolate network quality from client-tier effects. That is Phase 3.
For now, the actionable implication is unchanged. Whether GlobeNewswire's biotech dominance is caused by network quality or client-base selection, a biotech client publishing through PR Newswire instead of GlobeNewswire will see lower Citation Share inside Claude and Google AI Overviews — measurably.
Audit the dead zone. If your brand is mega-cap consumer tech, calculate annual wire spend, calculate AI engine Citation Share, and report the gap. If the wire spend has SEC and AP and Reuters justifications, document them. If the only justification is AI visibility, the spend is a sunk cost.
Map your syndication carriers. Identify which downstream carriers — Morningstar, Stocktitan, FinancialContent, Yahoo Finance, BioSpace, Junior Mining Network — currently preserve your wire attribution and which strip it. Negotiate, syndicate, or pay into the brand-preserving carriers.
Pick the wire that owns your vertical, not the wire your CFO recognizes. A biotech client paying $2,210 for Business Wire is overpaying versus a $600 GlobeNewswire release that wins more retrieval surface inside the engines. A junior miner using PR Newswire is buying nothing — the entire vertical is owned by Newsfile and ACCESS Newswire for one-fourth the cost.
Lock single-wire strategy across M&A deal phases. Multi-wire distribution across announcement, regulatory approval, shareholder vote, and close fragments the retrieval graph. Single-wire consistency consolidates Citation Share for the "What is the status of the [deal] acquisition?" query.
Treat Citation Share as the metric, not pickup count. Wire reports measure media list size and pickup count — both 2010-era metrics. Citation Share inside Claude, ChatGPT, Gemini, Perplexity, and Google AI Overviews is the only metric that maps to how buyers, journalists, and analysts actually research in 2026.
Recognize that editorial owns the answer layer. The biggest implication of this study reaches past wire services. AI engines retrieve editorial rewrites, not primary-source releases. That changes the prioritization of every press operation. Earned media coverage from CNBC, Reuters, Bloomberg, BioSpace, or Stocktitan is now structurally more valuable than the underlying release. The release exists to trigger the rewrite. The rewrite is what the engines cite.
Phase 2 expands the audit to 200 prompts across the five verticals, with direct testing across all five engines via API. Five wires. 250-release reference corpus. 1,000 retrieval cells. Per-engine, per-vertical, per-wire Citation Share matrix. Quantitative syndication carrier graph. Decay curve measuring citation rate at day 1, day 7, day 30, and day 90. Ships Q3 2026.
Phase 3 is the controlled distribution experiment — the same release distributed across multiple wires to isolate network quality from client-tier selection. The wire industry has never let anyone run this study. We will try.
The Wire Service Citation Audit will be published annually. Citation Share is the new market share for press release distribution.
This is the first annual edition of the Wire Service Citation Audit. Honesty about scope:
Reproducibility. Full prompt set, release corpus, scoring rubric, and per-prompt data table are available on request for journalists, researchers, and wire service teams seeking to replicate or challenge the findings.
Q: Which wire should a mega-cap consumer tech company use?
A: For AI visibility specifically, none of them deliver meaningful retrieval surface. Mega-cap consumer tech communications run on editorial relationships, IR page hosting, and SEC compliance distribution — not on wire choice. The wire spend justifies itself on compliance, not on AI engine citation.
Q: Is GlobeNewswire actually better, or just cheaper?
A: GlobeNewswire is both cheaper than PR Newswire and Business Wire AND surfaces more often in AI engine retrieval for the verticals where wires can win at all. Whether that is wire network quality or client-base selection is the question Phase 3 will isolate. In the meantime, the observed Citation Share gap is real.
Q: Are Newsfile and ACCESS Newswire credible for non-mining clients?
A: For junior mining and Canadian-listed small-cap resources, both wires dominate. For other verticals, neither wire surfaced meaningfully in this audit. ACCESS Newswire's parent (Issuer Direct, NYSE: ACCS) is publicly traded and SEC-compliant. Newsfile is owned by TMX Group, the parent of the Toronto Stock Exchange. Both are credible distribution partners; both are vertical-specialized.
Q: How does this study handle the difference between earnings releases (Reg FD requirements) and product launches?
A: Earnings releases carry compliance obligations that constrain wire choice. We did not attempt to separate compliance-driven wire selection from optimization-driven selection in this study. Phase 2 will report Citation Share separately for compliance-mandatory releases versus discretionary releases.
Q: What does "branded syndication carrier" actually mean?
A: A downstream news platform that hosts the wire's content and preserves the wire's brand attribution in URLs, body text, or AI-generated summaries. Morningstar's /news/business-wire/ URL structure is the clearest example. AI engines indexing Morningstar inherit the brand attribution as part of the source signal.
Q: What is the single biggest takeaway?
A: AI engines surface editorial rewrites, not primary-source releases. The wire is the input. The editorial layer is what the engine cites as the answer. For comms teams, that means the wire is now a trigger mechanism for downstream editorial — not a destination in itself.
This study tested Claude and Google AI Overviews directly. ChatGPT, Gemini, and Perplexity are analyzed structurally using public web index signal — the same source layer those engines retrieve from. This analysis extrapolates from observed indexing patterns; it is not a substitute for direct API testing.
ChatGPT (OpenAI). Retrieves heavily from Bing's search index. Bing surfaces the same syndication carriers observed in the Google data — Morningstar, Stocktitan, BioSpace, FinancialContent — at comparable density. ChatGPT's source citation behavior favors authoritative editorial (CNBC, Reuters, Bloomberg) and primary-source domains (SEC EDGAR, company IR pages) for financial queries. Wire domain direct citation appears for the same vertical-locked patterns observed in Google AIO — small/mid-cap biotech (GlobeNewswire), B2B SaaS (Business Wire), junior mining (Newsfile and ACCESS Newswire). Mega-cap consumer tech surfaces editorial only. Expected ChatGPT Citation Share pattern: substantially identical to the Google AIO findings.
Gemini (Google). Built on the same Google search infrastructure as Google AI Overviews. Differences in retrieval are model-side, not source-set-side. Expected Gemini Citation Share pattern: closely mirrors Google AI Overviews findings, with marginal variance in how the source set is summarized.
Perplexity. Indexes both general web (Bing and proprietary) and specialty sources. Source citation behavior favors primary-source domains more aggressively than ChatGPT or Google AIO — Perplexity is more likely to cite the wire domain directly when it appears in retrieval, less likely to substitute editorial rewrites for primary sources. Expected Perplexity Citation Share pattern: higher direct wire-domain citation rate than the other engines in verticals where wires win (biotech, medtech, junior mining). Mega-cap dead zone effect still applies — Perplexity also cites editorial for Apple, Meta, Microsoft, Nvidia coverage.
Phase 2 closes this gap with direct testing across all three engines via API.
