How much Reddit is actually in AI answers?
The claim that Reddit dominates AI answers is repeated constantly and sourced rarely. No assistant operator publishes citation shares by domain. Everything below comes either from a vendor that sells visibility monitoring or from a single academic-grade browsing panel, and the two disagree about emphasis in a way that is more instructive than either on its own.
The largest published dataset is Profound's, released on 5 June 2025 and updated in August 2025: 680 million citations observed across ChatGPT, Google AI Overviews and Perplexity between August 2024 and June 2025. Profound sells answer-engine optimisation software and raised a $180 million Series D; a company in that business has an interest in the finding that AI citations are concentrated and therefore gameable. The numbers are still the best available, and they are reported here with that stake named.
Two things in them matter. The first is that Reddit leads two of the three platforms — 2.2% of all Google AI Overviews citations and 6.6% of all Perplexity citations, ahead of YouTube in both. The second is that leading is not the same as dominating. A domain can be the most-cited site on the internet and still account for one citation in fifty.
ChatGPT behaves differently again. There Wikipedia takes 7.8% of citations and Reddit 1.8%, behind an encyclopedia and ahead of Forbes and G2 at 1.1% each. If you are optimising for one assistant you are not optimising for the others, a split we set out in more detail in which sources AI assistants actually cite.

The top six rows are the same citations counted against two different denominators. Share-of-top-ten is the figure usually quoted; share-of-all-citations is the one that tells you how often a Reddit link actually appears. Profound does not publish the prompt set behind the dataset, so the query mix is unknown.
Against that sits the one measurement nobody is selling anything with. The Pew Research Center's browsing study of 900 US adults, published 22 July 2025, found that the most frequently linked sources in Google AI summaries were Wikipedia, YouTube and Reddit — the same three that lead standard search results. Collectively they accounted for 15% of the sources listed in the AI summaries Pew examined, and 17% of the sources in standard results.
That comparison deserves to be read slowly, because it cuts against the story. On Pew's data, AI summaries draw on the big three community and reference sites slightly less than ordinary Google results do. Reddit's prominence in AI answers is, on this evidence, largely inherited from its prominence in search rather than created by the assistants. The related finding — that a link inside a summary is clicked about 1% of the time — is covered in do AI Overviews reduce clicks.
Why is Reddit cited so heavily?
Three reasons, of which only one is a deal.
Demand. Google's own announcement says the quiet part directly: “Over the years, we've seen that people increasingly use Google to search for helpful content on Reddit to find product recommendations, travel advice and much more. We know people find this information useful, so we're developing ways to make it even easier to access across Google products.” The behaviour preceded the partnership. Appending “reddit” to a query was a widespread user habit before any money changed hands.
Shape. Reddit's corpus is question-and-answer text about specific products, written by people with no obligation to be positive, with a visible score attached to each answer. That is unusually close to the form an assistant needs when a user asks for a recommendation — a point that recurs in how AI assistants decide which companies to recommend.
Access. On 22 February 2024 Reddit announced it had expanded its partnership with Google, “via our Data API”, to provide “programmatic access to new, constantly evolving, and dynamic public posts, comments, etc.” and to enable Google “to use the Reddit Data API to improve its products and services — including supporting new ways to display Reddit content and providing more efficient ways to train models”. Google's post the same day, by vice president Rajan Patel, described getting “efficient and structured access to fresher information, as well as enhanced signals that will help us better understand Reddit content and display, train on, and otherwise use it”.
On 16 May 2024 Reddit announced the equivalent with OpenAI: “OpenAI will bring Reddit content to ChatGPT and new products… To do so, OpenAI will access Reddit's Data API, which provides real-time, structured, and unique content from Reddit.” OpenAI also became a Reddit advertising partner. Steve Huffman's quote in that announcement is the one worth keeping: including Reddit in ChatGPT “helps people find more of what they're looking for, and helps new audiences find community on Reddit”.
What do the deals actually buy?
Less than the phrase “licensing deal” implies, and the clearest statement of the limit comes from Google itself: “This expanded partnership does not change Google's use of publicly available, crawlable content for indexing, training, or display in Google products.” Google was already crawling Reddit. What it bought was structure, freshness and signals — a firehose instead of a crawl.
Reddit was explicit that the arrangement is about access rather than rights transfer: the partnership “does not change Reddit's Data API Terms or Developer Terms, which state content accessed through Reddit's Data API cannot be used for commercial purposes without Reddit's approval”. The same sentence appears verbatim in the OpenAI announcement. Access is the product; permission is licensed, not sold.
The price is partly public. Reddit's S-1, filed 22 February 2024, disclosed that “In January 2024, we entered into certain data licensing arrangements with an aggregate contract value of $203.0 million and terms ranging from two to three years”, with a minimum of $66.4 million to be recognised in 2024. That is audited and it is the figure to use. The widely repeated “about $60 million per year” for the Google deal specifically comes from Reuters on 22 February 2024, attributed to one unnamed source of three the reporters spoke to; Reddit and Google both declined to comment. It is plausible and consistent with the S-1, and it has never been confirmed by either party.
What the deals became is visible in Reddit's accounts. “Other revenue” — the line holding content licensing, plus Reddit Premium and Gold, which the filings describe as “not material” — went from $15.2 million in 2023 to $114.7 million in 2024 to $140.0 million in 2025, against total 2025 revenue of $2.20 billion.
“Other revenue”, $ millions, calendar years
Source: Reddit, Inc. Annual Report on Form 10-K for the year ended 31 December 2025, filed 6 February 2026, Note 3 — Revenue.
“Other revenue” is content licensing plus products sold directly to users; the filing states the direct-to-user products were not material in these periods, so the line is close to a licensing figure but is not labelled as one. Total revenue was $2,202.5m in 2025, making this line about 6% of the business.
Two limits on reading that as a citation guarantee. First, a licensing agreement is a supply contract, not an editorial commitment: neither Google nor OpenAI has published any undertaking about how often Reddit will be cited, and the Tow Center found that publisher licensing deals bought no accuracy at all in attribution — see how often AI search tools cite the wrong source. Second, the arrangement is terminable. Reddit's own 10-K lists as a risk that “our existing content licensing agreements may be terminated, not renewed, or renewed on less favorable terms”, and that “the value of content for AI training purposes may be reduced over time”.
What about everyone else's crawlers?
Reddit closed the open door at the same time it opened the paid one. On 25 June 2024 it announced an update to its robots.txt file, saying it would “continue rate-limiting and/or blocking unknown bots and crawlers from accessing reddit.com”, with an explicit carve-out for the Internet Archive and other good-faith non-commercial actors. The 10-K describes the problem it was responding to: “third parties often attempt to access and collect Reddit site data through ‘scraping’ and other unauthorized mechanisms for unauthorized purposes, such as distributing such data to other parties for commercial purposes or training AI models for commercial purposes.”
The practical consequence for anyone reading citation studies is that Reddit's presence in an assistant now has two possible routes — licensed API access, or a historical scrape sitting inside a training corpus such as Common Crawl — and published citation counts cannot distinguish them. An assistant with no agreement can still reproduce Reddit content it learned in training without ever fetching a URL. This is the same ambiguity that makes telling an AI not to train on your site a weaker instrument than it sounds.
What this means if you cannot post there
Most companies cannot use Reddit the way a visibility pitch implies, and the obstacle is written into the site's rules rather than left to custom.
Reddit Rule 2: “Abide by community rules. Participate authentically in communities where you have a personal interest, and do not spam or engage in disruptive behaviors (including content manipulation) that interfere with Reddit communities.” Rule 5: “Be authentic. You don't have to use your real name, but do not intentionally mislead others or impersonate an individual or entity in a deceptive manner.” The published enforcement ladder runs from “asking you nicely to knock it off” to permanent account suspension, removal of content and banning of entire communities.
Individual subreddits are stricter than the sitewide rules, and moderators — not Reddit staff — enforce them. An agency offering to seed your brand into relevant threads is offering to break Rule 2 on your behalf, using accounts you do not own, in communities whose moderators remove that material as a matter of routine. The upside is a mention in a corpus assistants read. The downside is a site-wide association between your brand name and manipulation, in the same corpus.
Three things are worth doing instead.
Read it as research, not inventory. The threads that already rank for your category are a free, unusually candid record of what buyers object to. Those objections are the ones an assistant will surface when someone asks whether your product is any good. Answering them in material you do control — documentation, comparison pages, earned coverage — is the available move, and it is the mechanism described in what a company can and cannot influence about AI answers.
Participate as a person, under your own name, where the rules allow it. Rule 5 does not prohibit identified participation; it prohibits deception. Some subreddits permit verified vendor accounts answering direct questions and ban everything else. That is a narrow, slow, legitimate channel, and it is not a distribution plan.
Do not buy the causal claim. No published study demonstrates that a brand mention appearing in a Reddit thread causes an assistant to recommend that brand. The citation studies show which domains get linked; they do not show what happens when a specific company's name is added to one. Anyone selling Reddit work on the strength of the 46.7% figure is selling a share-of-top-ten statistic as if it were a probability that your company gets mentioned.
Media Morpheus sells media and podcast placement, not forum posting, and the evidence here does not support adding it. Reddit is the clearest case in the field of a source that matters enormously to AI answers and is almost entirely closed to paid influence — which is a useful thing for a buyer to know before paying anyone to try.
Methodology and limitations
Citation-share figures are from “AI Platform Citation Patterns: How ChatGPT, Google AI Overviews, and Perplexity Source Information” by Nick Lafferty, Profound, published 5 June 2025 and updated August 2025, covering 680 million citations observed between August 2024 and June 2025. Four limits apply. Profound sells answer-engine optimisation software and has a commercial interest in the finding that citations are concentrated among identifiable domains. The prompt set generating the citations is not published, so the query mix — consumer, B2B, informational, transactional — is unknown and cannot be matched to any particular company's category. The dataset is a rolling observation of products that change continuously, and the shares will have moved. And the two framings Profound publishes — share of all citations, and share within each platform's top ten domains — differ by roughly a factor of seven for Perplexity; quoting one without the other misstates the result by that factor. The non-commercial comparison is Pew Research Center, 22 July 2025, from the browsing records of 900 US adults, which reports Wikipedia, YouTube and Reddit as a combined 15% of AI summary sources but does not break Reddit out separately; that is why the per-platform figures here are vendor figures. Deal terms and quotations are taken from the parties' own announcements on redditinc.com and blog.google and from Reddit's SEC filings; the $60 million-a-year figure for the Google contract specifically is Reuters reporting attributed to a single unnamed source and has not been confirmed by either company. Financial figures are from Reddit's Form 10-K for FY2025, filed 6 February 2026, and its Form S-1, filed 22 February 2024. We found no study, vendor or academic, testing whether adding a brand mention to a Reddit thread changes an assistant's recommendation; the absence is stated rather than filled.
Conclusion
Yes — more than any other single domain in Google AI Overviews and Perplexity, and second only to Wikipedia in ChatGPT. But the honest magnitude is 2.2% and 6.6% of citations, not the 21% and 46.7% share-of-top-ten figures that circulate, and the only non-commercial measurement suggests the assistants lean on Reddit slightly less than ordinary search already did. Google and OpenAI pay for structured, fresh access; Google says plainly that this changed nothing about its right to crawl the same content for free. For a company, the finding that matters is the one that cannot be bought around: the corpus assistants read most heavily is governed by rules that prohibit exactly the kind of participation a marketing budget can buy.
Frequently Asked Questions
How much Reddit is actually in AI answers?
Less than the headlines suggest, and it depends which assistant. On Profound's dataset of 680 million citations collected between August 2024 and June 2025, Reddit was the most-cited single domain in both Google AI Overviews and Perplexity — but at 2.2% and 6.6% of all citations respectively. In ChatGPT it was second to Wikipedia at 1.8%. Pew, the only non-commercial measurement, found Wikipedia, YouTube and Reddit together accounted for 15% of the sources listed in the AI summaries it examined.
Why is Reddit cited so heavily?
Partly because people search for it: Google's own announcement says “people increasingly use Google to search for helpful content on Reddit to find product recommendations, travel advice and much more”. Partly because both Google and OpenAI hold commercial agreements giving them structured access to Reddit's Data API, announced on 22 February 2024 and 16 May 2024 respectively.
What do the Google and OpenAI deals actually cover?
Programmatic access to Reddit's Data API, which Google describes as delivering “real-time, structured, unique content” plus “enhanced signals”. Google states explicitly that the deal “does not change Google's use of publicly available, crawlable content for indexing, training, or display”. Neither company has published a commitment about how often Reddit will be cited.
How much is Reddit paid for this?
Reddit's S-1, filed 22 February 2024, disclosed data licensing arrangements entered in January 2024 with an aggregate contract value of $203.0 million over terms of two to three years. Reuters reported the same day, citing one anonymous source, that the Google contract alone was worth about $60 million a year. Reddit's FY2025 10-K reports $140.0 million of “other revenue”, the line that contains content licensing, against $2.20 billion of total revenue.
Can a company get itself mentioned on Reddit?
Not by posting promotionally. Reddit Rule 2 requires participation “authentically in communities where you have a personal interest” and prohibits spam and content manipulation; Rule 5 prohibits impersonating an entity in a deceptive manner. Individual subreddits impose stricter rules and moderators remove vendor posts routinely. Agencies that sell Reddit seeding are selling a rule violation, and the enforcement list in Reddit's own rules runs to permanent account suspension and community bans.
So what should a company do about it?
Treat Reddit as a measurement surface rather than a placement surface. Read the threads that already rank for your category to see what the objections are, answer them on your own site and in earned coverage, and accept that the thread itself is not a channel you control. No published study shows that a brand mention appearing in a Reddit thread causes an assistant to recommend that brand.
