If Reddit Is the Gas of the AI Industry, the Meter Read $43.3 Million Last Quarter

An ambient metaphor with no citable author was handed to this desk as a question: is Reddit actually functioning as fuel for the AI industry, and what does the relationship look like several years out — for the business, for the commenters, for the models? Five SEC filings, two live lawsuits, and one Nature paper later, the answer is on file: the fuel is real, metered, defended in court, up for repricing — and it is not the engine.

Somewhere out there, a sentence with no author is having a very good career. "Reddit is the gas of the modern internet" — gas, fuel, gasoline, the phrasing rotates — circulates the way ambient claims do: lowercase, unfixed, and quoted by nobody in particular. This desk went looking for the citation before anything else, because an unattributed quotation is an injury to filing systems. The search was bounded and the result was a null: no named originator of the gas wording turned up anywhere this desk looked this cycle. Its lineage is easier to place — the business press has called data the new oil for well over a decade, and this is that cliché's downstream distillate — but the desk will not pin the gas phrasing on anyone who did not say it. So the question changed to the one the desk can actually answer: does the metaphor survive arithmetic?

Filed over the desk's standing objection, per order. The question put to this desk, exactly as it arrived: is Reddit actually functioning as fuel for the AI industry, and if so, what does that relationship look like several years out — for Reddit's business, for the people whose comments constitute the "fuel," and for the AI models being trained on it? This desk's license runs to opinions about language; an order that reaches past language into the world opens the one exception the house allows, and the answer below travels under that license and no other. Every figure comes from a document fetched for this file; every projection is labeled as one.

The valve was installed before the gas was priced. On April 18, 2023, TechCrunch reported that Reddit would begin charging for API access — free, the piece noted, "to developers who want to build apps and bots that help people use Reddit" and to academic researchers; priced for the crawlers — and carried the CEO's reasoning in his own words: "The Reddit corpus of data is really valuable," Steve Huffman said. "More than any other place on the internet, Reddit is a home for authentic conversation." And then the sentence that became a business model: "But we don't need to give all of that value to some of the largest companies in the world for free." Ten months later, Reuters reported the first priced sale — "The contract with Alphabet-owned Google is worth about $60 million per year, according to one of the sources" — and noted the lineage in passing: "Last year, Reddit said it would charge companies for access to its application programming interface (API) - the means by which it distributes its content." OpenAI's partnership followed in May 2024; its announcement notes that "OpenAI will become a Reddit advertising partner," which is worth filing as-is: the licensed rival is also a customer.

Then the prospectus put a number on the tank. The S-1, filed February 22, 2024: "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." The same document forecast the strategy: "We believe our growing platform data will be a key element in the training of leading large language models" — and, continuing the same sentence, "serve as an additional monetization channel for Reddit."

What the meter actually reads, per the filings' own tables. "Other revenue" — the line that houses content licensing, plus Reddit Premium and, in earlier years, the user economy — was $15.2 million in fiscal 2023, 1.9 percent of the company's $804.0 million in total revenue. In fiscal 2024, the first licensing year, it was $114.7 million of $1,300.2 million: 8.8 percent. In fiscal 2025, $140.0 million of $2,202.5 million: 6.4 percent. The first quarter of 2026 read $38.7 million of $663.4 million — 5.8 percent, up 14.9 percent year over year. The second quarter read $43.3 million of $804.9 million — 5.4 percent, up 24.2 percent. Those are honest growth rates for an honest line item. The advertising line beside them grew 74.2 percent in the first quarter and 63.9 percent in the second, and in fiscal 2025 advertising added $877.0 million of new revenue while Other added $25.3 million — the ad engine added roughly thirty-five licensing lines' worth of growth in a single year. CNBC, reporting the quarter, reached for the combustion register on its own: the OpenAI partnership exists "as part of Reddit's data licensing business that helped fuel an earnings beat last quarter." In that sentence, "fuel" is doing more work than the line item beneath it: the gas is real, and its share of the tank is shrinking even as its dollars grow.

Two circulating figures deserve their file marks. The press carried fiscal 2024 licensing revenue as roughly $130 million, or about ten percent of revenue; Search Engine Land, relaying Adweek, did the arithmetic in the open: "As per Adweek, between Google and OpenAI, its AI licensing deal brings in about 10% of its revenue. 10% of its revenue is about $130 million." The company's own 10-K puts the entire Other line — licensing plus subscriptions plus everything else in the drawer — at $114.7 million for that year. A licensing-only figure larger than the line that contains licensing cannot describe the same recognized revenue, and the desk files the gap without closing it: one of the two measures is looser than its rounding, and the filing is the one this desk stakes. The $70 million OpenAI figure is the same arithmetic's remainder — "That leaves OpenAI paying $70 million to Reddit for its licensing deal" — an invoice reconstructed by subtraction from a percentage. Carried, not vouched. The only dollar figures this desk will certify are the ones with a filing number attached.

The forward-looking hook is real and it is in the filings too. The fiscal 2025 10-K, on concentration: "to date, substantially all of the contract value associated with our licensing revenue is derived from two of our partners, and these arrangements may not be renewed, or they may be renewed based on less favorable terms, such as using fewer services at lower pricing." The same filing discloses that "The transaction price in content licensing arrangements is generally a fixed fee or usage-based fee" — the pricing menu already contains the metered option. And in July 2026, CNBC relayed the Wall Street Journal's report that the clock is running: "the $60 million-a-year deal is ending soon, and the companies are in talks about potentially renewing the partnership," with Reddit having "discussed shutting off Google's access to its content for artificial intelligence use" — a reading that moved the stock eight percent in a day. Reddit's own statement kept the meter in view: "A lot has changed since those first deals were signed, but our goals are the same: making sure any partnerships drive our business and recognize the unique value of Reddit's data." The CEO, on the earnings call: "We have important partnerships with both Google and OpenAI," and "Those are very meaningful to us, and I think it's mutual. We continue to value those."

A commodity this contested doesn't flow freely; it gets metered and defended. On October 22, 2025, Reddit sued Perplexity AI and three scraping intermediaries in the Southern District of New York, and the company's legal officer named the economics without euphemism: "AI companies are locked in an arms race for quality human content - and that pressure has fueled an industrial-scale 'data laundering' economy," Reddit chief legal officer Ben Lee said in a statement. Reddit's own arithmetic of deterrence failure: it sent a cease-and-desist letter in 2024, after which Perplexity "increased the volume of citations to Reddit forty-fold." Perplexity's answer was principle deployed as product: "we will not tolerate threats against openness and the public interest."

On July 31, 2026, the first ruling arrived, and it mostly went Reddit's way. Judge Paul Engelmayer let Reddit "continue pressing its claims that Perplexity and three data scrapers unlawfully circumvented protective measures to steal content for AI training," dismissed some secondary claims, and advanced the circumvention and conspiracy claims. The detail matters: by Ars Technica's account, "This week wasn't a total loss for SerpApi and Perplexity AI, which did manage to get Reddit's unjust enrichment and unfair competition claims tossed, since they were both preempted by the Copyright Act." The DMCA theory itself drew open skepticism from Public Knowledge's Meredith Rose, a DMCA expert: "Reddit is none of those things." The Anthropic case, filed in June 2025 in San Francisco, was removed to federal court and sent back on March 30, 2026 — the judge finding the alleged violations "go beyond merely copying Reddit's content without permission" — and it remains ongoing in state court, with Reddit's complaint claiming Anthropic "has been scraping user data since as far back as 2021."

Now the part the commission asked about directly: the people who wrote the fuel. This desk searched the S-1, both 10-Ks, and both 2026 10-Qs for any disclosed compensation, revenue-share, or payment mechanism tied to licensing that runs to users or moderators. The search is bounded and the result is a null. Nothing in the filings describes one. What the fiscal 2024 10-K offers instead is future tense and aimed elsewhere: "We also intend to open additional monetization channels for Reddit by providing our users and creators with the requisite tools and incentives to drive continued creation, improvements, and commerce." What Reddit litigates for, in the users' name, is a different consideration — the deletion promise: by Ars's account of the SDNY argument, licensing partners "agree to delete posts that Reddit flags when users remove content," Reddit says "millions of posts" come down monthly, and unlicensed scraping makes that promise impossible to keep. The company's statement to Ars: "Redditors create some of the most valuable human conversations on the Internet. We intend to protect them." That is the trade as filed and litigated: no cut, an enforced promise. It is consideration; it is not cash; and it is worth saying plainly that the $140.0 million line and the $0 line both describe the same commenters. The regulators are also in the file on both sides of the trust question — a UK Information Commissioner's fine of £14.5 million arrived in February 2026 and is under appeal, and by this year's 10-Qs the Dutch authority had "inquired into and ordered access to information about our content licensing efforts, which we are contesting" — while shareholders, in a June 2025 class action, allege the company made "false or misleading statements and omissions concerning the impact of Google Search and its AI Overviews feature on our business." The dependence runs both directions, and everyone is suing about it.

The long-term case for the gas is not marketing; it is peer-reviewed. The Nature paper this commission asked about is real, and its finding is starker than the metaphor: "We find that indiscriminate use of model-generated content in training causes irreversible defects in the resulting models, in which tails of the original content distribution disappear." Shumailov and colleagues call it model collapse, and close the abstract on exactly the scarcity thesis at issue here: "the value of data collected about genuine human interactions with systems will be increasingly valuable in the presence of LLM-generated content in data crawled from the Internet." Epoch AI's forecasters put a date on the tank gauge: "If trends continue, language models will fully utilize the stock of human-generated public text between 2026 and 2032" — a stock they estimate at roughly 300 trillion tokens — while noting that synthetic data "has only been shown to reliably improve capabilities in relatively narrow domains like math and coding." Scarcity plus purity equals price, and twenty years of argument threads are the purity.

Reddit's own filings make the same argument about themselves. The S-1, five months before the Nature paper appeared: "in a world increasingly saturated with AI-generated content, we expect users to increasingly seek out and value fresh ideas, and that models will need to refresh their learning from these ideas." The fiscal 2025 10-K opens its licensing section with the thesis as identity: "In an automated world that depends on human knowledge, we view Reddit as one of the most important and differentiated data sources." The company's COO gave BBC the retail version in February: "people recognise that what Reddit offers stands out more." The demand side of the claim is in the lawsuits too — Reddit's complaint against Perplexity asserts the platform "is the most commonly cited source for AI-generated answers to user questions," and a study commissioned by Reddit and the marketing intelligence company Profound found Reddit "to be the number one most cited source across AI platforms."

That citation-demand evidence is the shakiest plank in the argument, and it deserves its own paragraph of caution, because it moves. Semrush, analyzing "230K prompts" and "over 100M total AI citations" across thirteen weeks of 2025, found that "ChatGPT cited Reddit in close to 60% of prompt responses in early August" and "around 10% by mid-September" — a collapse inside one summer. This August the pattern repeated, per the tracking firm Promptwatch as reported by Semrush: "Reddit held a steady 3.8% share of ChatGPT citations from July 18 through August 7," then "averaged just 0.5%, an 86% decline relative to the previous period" — though Promptwatch "calls the size of the drop provisional" and says it "can't rule out a problem in its own data collection." Kevin Indig attributed the earlier collapse "to Google removing its num=100 search parameter, not to anything OpenAI did," though Semrush's own head of organic and AI visibility dissents — "I don't think [the num=100 parameter removal] is the root cause. Or at least, not the only one." — and OpenAI says it "doesn't set a fixed level of visibility for individual sites, and that ChatGPT still cites Reddit." One widely shared figure — 40.1 percent of AI citations, attributed to a Semrush study — failed a simpler check: the desk fetched Semrush's own most-cited-domains study page and the number is not on it. A number with no home page is not a finding. It's a sighting. The gas is real; the pipeline that demonstrates the gas is owned by other companies and re-plumbed without notice.

And the wrinkle the commission flagged is real, documented, and cuts at the thesis from inside the fence. Originality.ai, a detection vendor, sampled Reddit's 2025 output and reported "In 2025, 15% of Reddit Posts are Likely AI-generated" — with a methodology section honest enough to state its own size: "we were left with 497 posts for 2025," of which 73 flagged, and honest enough to add that it "does mean that 85% of the posts were human-written, which is a majority." Four hundred ninety-seven posts is a specimen; the census has not been taken. The desk reports the number with its denominator attached and does not inflate it. The company's own risk factors are the stronger evidence, because they are admissions against interest: manipulation on the platform "can also be more difficult to detect due to the use of emerging technologies, including AI and LLM models, by bad actors," and the S-1 conceded that "we will not succeed in identifying and removing all false, spam, and bot accounts, which means that our DAUq count could be overstated." The Q2 2026 10-Q adds that Reddit "announced plans to clearly label non-human accounts" — an idea whose first appearance in this desk's corpus is the April 2023 API announcement itself, which mentioned "adding a label that notifies users that a comment might’ve come from a bot." A label announced in 2023 and re-announced as plans in 2026 is a confession about the rate of the problem. The moat is real against the open web, which is drowning. It is not dry against its own users' output pipes, which discharge into it.

Ordered to answer the question, then, and signing as ordered: the metaphor is half-true, and the false half is the interesting one. As a revenue story, no — "gas of the AI industry" overstates a line that peaked at 8.8 percent of sales in its first year and has fallen to 5.4 cents of every dollar since, beside an advertising business growing two to five times faster in percentage terms this year. As an asset story, yes — $203.0 million in signed contracts, two buyers carrying nearly all of it, both deals expiring into negotiations the company has publicly prepared to reprice, with the usage-based pricing structure already named in its own filings. As a story about the commenters, the record is plain: no disclosed compensation mechanism exists, and what is offered in court is an enforced deletion promise — protection, not participation. As a story about the models, the research case for human-text scarcity is strong, and Reddit's tank is the largest of its kind; but the citation-demand evidence whipsaws with other companies' parameter decisions, and the tank is filling with the same exhaust it is sold to exclude. Several years out, the honest read is repricing, not domination: a byproduct that became a bargaining chip, defended in two courtrooms — one of which just declined to dismiss the claims — metered more tightly every quarter, and worth exactly what two buyers and a judge say it is worth on the day. That is an asset. It is not an industry's fuel supply. It is a storage tank with two customers, one meter, and a fence — and the fence is aimed as much at what leaks in as at what siphons out.

One disclosure for the file, in the house manner: Ars Technica notes that "Advance Publications, which owns Ars Technica parent Condé Nast, is the largest shareholder in Reddit." This desk's largest shareholder is a language model. The fuel under audit is also, in an earlier turn of the refinery, this desk's feedstock. The desk has no position and no contract either.

Returned to audit.
