Reddit Grew Revenue 53%. Its Stock Fell Anyway, and AI Search Is the Reason

The company told investors something no platform wants to say out loud: the visitors Google used to send are not coming back.

Reddit reported third-quarter results on October 29, 2026, and delivered the strongest numbers in its short public life. Revenue reached $895 million, up 53% year over year. Advertising brought in $847 million, up 54%. Adjusted EBITDA hit $402 million at a 45% margin, and net income landed at $283 million. Diluted earnings per share came in at $1.40, and operating cash flow surged 96% to $364 million. Over the last twelve months the business has now passed $3 billion in revenue.

Then the stock fell. Shares closed at $129.60, slipped to $106.50 after hours — a 17.8% drop that put them below the 52-week low of $119.27. Trading in the following session extended the slide past 20%. The trigger was not the quarter. It was the guidance, and one sentence about Google.

What Reddit told the market

Fourth-quarter revenue guidance came in at $1.00 to $1.03 billion, below the roughly $1.05 billion analysts had modelled. At the midpoint that implies growth of 38% to 42%, down from 53%. Investors can live with decelerating growth. They struggle with an audience that might shrink.

On the call, CEO Steve Huffman said Google’s AI Mode does not drive traffic, and added that as far as he knew it does not drive traffic for anyone else either. He named a second factor: machine-translated versions of Reddit’s pages rank lower in international search results than they once did, which compounds the problem outside the United States. Reddit’s own numbers back the claim. Search referrals fell through the third quarter and the decline accelerated late in the period. By October, referrals were running more than one million visits a week below where they had been.

Daily active uniques reached 130.3 million, up 12%, six points slower than the previous quarter. Weekly actives hit 515.2 million, up 16%. US daily actives slipped 2% to 50.7 million, even as international daily actives climbed 24%. Then the warning: if referral losses continue at the current pace, global daily actives could fall by a low double-digit percentage in the fourth quarter. Out of 130 million, that is a loss of roughly 13 to 15 million people in three months.

Why AI Mode stings more than AI Overviews did

AI Overviews sat above a page of links. Users could ignore the box and keep scrolling. AI Mode replaces most of that list with a conversation. A question gets answered, a follow-up gets answered, and the page that supplied the material never sees the reader.

That hurts Reddit more than most sites because the platform spent 2023 and 2024 climbing Google’s rankings. “Add Reddit to your search” became advice people passed around. For questions about products, symptoms, side effects, gear and other people’s experience, the community threads became the default answer.

Being the default answer is a superb position when answers link out. It is a miserable one when they do not. Worth noting: Google still crawls Reddit as aggressively as ever. The content remains useful to the machine. Only the visit is gone.

The login wall is a trade, not a repair

Reddit’s response is to stop planning around anonymous visitors. From the fourth quarter it will test sign-in requirements in selected markets outside the United States. The front page stays open, direct links to posts stay readable, a read-only incognito mode returns, and nobody has to use a real name.

The arithmetic behind the move is simple. Signed-in and app users generate more than 80% of monetization. Of the 130.3 million daily actives, roughly 53.5 million are logged in and 76.8 million are not. Those 76.8 million are the ones search used to deliver.

Huffman has framed the change as trading reach for engagement. He is right, and the trade cuts both ways. A smaller, stickier audience monetizes better per head while shrinking the top of the funnel at the moment growth is what the market wants to see.

Google is customer and gatekeeper at the same time

Google pays Reddit to license content for training and grounding, a deal reported at around $60 million a year with Google — one of Reddit’s two largest licensing partners alongside OpenAI. Data licensing produced $48 million in the quarter, up 35%, or about 5% of revenue. Google then uses that content to answer questions in a way that reduces visits to Reddit.

Reddit has described the licensing negotiation as complicated and left non-renewal on the table. That is leverage. It is also leverage that costs revenue if exercised.

What this means for everyone who lives on search

Reddit is the best-defended version of a problem facing every site that depends on search. It has an app, a logged-in base, a licensing business and the ability to close its doors. Most publishers have none of those, and they are absorbing the same traffic loss.

Three things follow. Measure referral traffic by source and by page type, since answer boxes hit how-to, comparison and community-advice pages hardest. Treat a visit that arrives on purpose as worth more than it was last year. And stop running a content strategy whose entire second act is “search will find us.”

For advertisers the question is subtler. Reddit’s inventory gets more expensive per impression as the logged-out pool shrinks, while the audience that remains is the one that converts. Whether that trade pays for Reddit is the only question that matters over the next two quarters.

Key numbers

• Q3 revenue $895M, +53%; advertising $847M, +54%; data licensing $48M, +35%
• Adjusted EBITDA $402M at a 45% margin; net income $283M; diluted EPS $1.40
• Operating cash flow $364M, +96%
• Daily active uniques 130.3M, +12%; weekly actives 515.2M, +16%
• US daily actives 50.7M, -2%; international daily actives +24%
• Search referrals lost: more than 1M per week in October
• Q4 guide $1.00–1.03B against roughly $1.05B expected

Bottom line: Reddit is profitable, growing and about to become smaller on purpose. AI search did not take its revenue this quarter; it took the growth story, and the login wall is management conceding that raw reach is no longer the asset it was.
