AI Wants Reddit's Data. So Why Has It Become Reddit's Problem?

On October 29, 2026, Reddit, the U.S. community platform, reported its third-quarter results. Revenue rose 53% year over year to $895 million, and net income grew 74% to $283.3 million. It was a quarter that beat market expectations.

The next day, Reddit's stock fell 29%, its largest single-day drop since going public in 2024. Why would a stock collapse after strong results? To answer that, it helps to start with what Reddit is and how it grew.

What Is Reddit?

Reddit is an online community platform founded in the U.S. in 2005. It once called itself "the front page of the internet," and for good reason: it was where the internet's conversations gathered.

Reddit is organized into topic-based forums called subreddits. There is a subreddit for almost anything, from programming and personal finance to parenting and individual laptop models, and most are run by volunteer moderators. Users upvote and downvote posts and comments so the most useful answers rise to the top.

The scale is significant. In Q3 2026, Reddit averaged about 130 million daily active uniques (DAUq) and more than 500 million weekly active uniques. These figures count users Reddit identifies by unique identifiers, so they are not exactly the same as the number of people. Reddit's archive holds more than 27 billion posts and comments.

What makes Reddit distinctive is that these posts come from people who have actually been there. Many users got into the habit of adding "reddit" to the end of their searches when looking for product reviews or travel tips, because they trusted honest firsthand experience over promotional content.

How Reddit Has Made Money

Reddit's business model is simple: place ads where people gather. Of its $895 million in Q3 2026 revenue, $847 million came from advertising, close to 95% of the total.

For a long time, though, revenue did not keep pace with the size of its audience. Even in 2023, the year before its IPO, Reddit posted a net loss of $90.8 million.

Things changed after the IPO. Reddit listed on the New York Stock Exchange in March 2024 at $34 per share, and as its ad business grew quickly, it began posting quarterly profits from Q3 2024. It went on to record eight consecutive quarters of more than 60% revenue growth through Q2 2026, and in Q3 its trailing twelve-month revenue passed $3 billion as it joined the S&P 500.

A New Spotlight as a Data Supplier for AI

Ahead of its IPO, data licensing added a new growth story for Reddit. In February 2024, Reddit expanded its partnership with Google, allowing Google to use Reddit posts for AI training and to improve its search services. The deal value was not disclosed, but Reuters reported it at about $60 million a year. In May of the same year, Reddit partnered with OpenAI, bringing Reddit content to ChatGPT.

For AI to talk and answer like a person, it needs real human conversation. Reddit had nearly two decades of questions and answers, reviews and debates. That is why a community platform like Reddit also began drawing attention as a supplier of AI training data.

What Shook Reddit

Reddit's leadership pointed to changes in Google's search results page as the cause of its declining search traffic. Through AI Overviews and AI Mode, Google now summarizes answers directly at the top of the results page. CEO Steve Huffman explained that because these features give users answers right away, fewer people are clicking through to Reddit from search.

In its Q3 shareholder letter, Reddit said search referral traffic was down meaningfully, with the decline accelerating later in the quarter. In October, search referrals fell by more than 1 million per week on average. On the earnings call, Huffman said AI Mode does not drive traffic to Reddit or to other sites, describing it as a fundamental change in how Google works.

The numbers reflect the shift. U.S. daily active uniques fell 2% year over year, and Reddit said that if the trend continues, total DAUq could fall in Q4 by a low-double-digit percentage from the current base of about 130 million. Add a Q4 revenue outlook ($1.0 billion to $1.03 billion) that came in below market expectations, and investors reacted to what lay ahead rather than to the quarter just reported.

There is a notable detail here. Huffman said Google is crawling Reddit as actively as ever. In other words, Google keeps collecting Reddit content while fewer users arrive at Reddit from search. The use of content and the return of visitors to the platform that created it have started to come apart.

Can data licensing revenue fill the gap? Not yet, it seems. Other revenue, which includes data licensing, grew 35% to $48 million in Q3, but that is only a little over 5% of total revenue. Most of Reddit's revenue still comes from advertising, and advertising ultimately depends on how many users come back and how often.

Reddit's Response: Closing the Door, Building Inside

Reddit's response comes down to controlling access to its data and growing the number of users who come directly. There are three concrete moves.

First, a shift toward logged-in use. Starting in Q4, Reddit is testing a logged-in-only experience in select markets outside the U.S., and it plans to use the results to shape how this will apply globally. Huffman cited better signals for ad targeting, higher engagement, protection of its data, and adapting to regulations around the world. Since logged-in and app users account for more than 80% of Reddit's monetization, the shift is both a data defense and a revenue strategy.

Second, ending public API access. On September 30, 2026, Reddit announced it would end RSS feeds on November 13 and phase out its public Data API. New requests for public API access stopped as of October 31; from January 12, 2027, Reddit will begin removing access for apps that have not registered; and in March 2027, remaining public access will end. Apps and bots that run within Reddit are being directed to its Developer Platform. Using Reddit data for AI training or commercial services, however, still requires Reddit's approval and a separate agreement under its existing terms.

Third, keeping answers inside Reddit. Reddit launched its AI search feature, Reddit Answers, in beta in December 2024, and weekly users grew from 1 million in Q1 2025 to 15 million in Q4 2025. It is an attempt to bring questions that used to end on Google's results page back to Reddit.

Logged-in and app users did grow quarter over quarter in Q3. Reddit is focusing on users who come directly and participate rather than visitors passing through from search, while managing data access through approved channels and terms of use.

The Question for Companies Building AI

What shook Reddit was not a drop in the value of its data. It was a structure in which that value no longer flows back naturally as visits and ad revenue. Even as data becomes more valuable, the platforms that create it are not guaranteed to profit from it. And when a platform changes its policies to protect its revenue, the collection routes of companies that relied on that data are shaken too.

Companies building AI services should consider the following about the data they use today.

1. Can we keep receiving the data we need reliably going forward?
2. Does our agreement cover our service's intended use and scope?
3. If our service needs current information, is the update cycle fast enough?
4. Is the data delivered in a structure and quality we can plug straight into our service?

If you have been collecting data from the open web, keep in mind that a single platform policy can cut off your collection route. And for AI services that handle current information, continuous, uninterrupted updates matter as well.

In the end, choosing data means looking beyond quality to whether rights are clear and supply is sustainable.
