Reddit lost close to a third of its value in a single session, and the quarter it just reported wasn't the reason. The traffic that Google's AI answers used to send is drying up, and the company's fix is to put a login wall in front of the site.
What Reddit Reported for the Third Quarter
Reddit published its third-quarter results on October 29, and on paper the numbers looked fine. Earnings came in at $1.40 a share against a consensus of $1.35. Revenue hit $895 million, ahead of the $878 million analysts had modeled.
Sales grew 53% from a year earlier. That's a fast clip for any advertising business of this size. It's also slower than the growth Reddit posted in earlier quarters, and investors had already priced in the faster version.
Users were the softer half of the report. Global daily active uniques, the count of people who show up at least once a day whether they log in or not, reached 130.3 million. That's up 12% year over year, but under the 133.7 million analysts expected.
The US line was worse. Domestic daily actives fell 2% to 50.7 million, against an expected 53.5 million. A mature market shrinking is a different problem from a young market growing slowly, and Reddit now has both.
The Fourth-Quarter Guide Did the Damage
Guidance, not results, sank the stock. Reddit told investors to expect revenue between $1.0 billion and $1.03 billion in the current quarter. Analysts were sitting at $1.05 billion.
Shares closed down 29.22% on October 30. That's the worst single day since the company went public in 2024, and it clears the previous mark of a 20.99% drop on July 31.
A company can beat on earnings and still get punished for the next three months. That's the whole story of this session. Nobody was re-pricing September. The market was re-pricing the arrangement Reddit runs on, which depends on people arriving from somewhere it doesn't control.
Where the Search Traffic Went
Steve Huffman, Reddit's chief executive, gave CNBC a plain answer about the missing referrals. Traffic from Google search "declined meaningfully in this quarter," he said, because users are moving to AI Mode and AI Overviews.
Those two products are easy to describe. AI Overviews are the short summaries Google writes above the results on many queries. AI Mode is the conversational version of the same thing. Both answer the question on the results page, so fewer people click through to a forum thread.
The trend has a number attached to it. On the earnings call, Reddit said search referrals were falling by more than a million visits a week on average during October, according to Yahoo Finance. Let that run for a full quarter and total daily users start to bend.
Reddit's own data supports the read. The people who leave are the ones who arrive cold, read one thread, and go. They cost bandwidth and ad inventory but produce little revenue, because advertisers pay for targeting they can't get from an anonymous visitor.
Why Reddit Is Testing a Login Requirement
The response Reddit announced is blunt. It will test requiring people to sign in before they can read content, starting outside the United States in the fourth quarter.
What logged-out visitors will still see hasn't been decided. Huffman described the rollout as one that involves a lot of complexity, which is corporate language for a change with many moving parts and no obvious safe default.
The trade is straightforward on paper. A login requirement converts some share of anonymous readers into accounts, and accounts carry history, subscriptions, and better ad targeting. It also loses the readers who won't bother, and search engines need to crawl public pages to keep sending anyone at all.
Huffman's Line, and Why He's Giving It Up
The most revealing part of the week was Huffman explaining his own reversal. Reddit, he told CNBC, is the last platform that still lets people read it without an account, and that openness, he said, is largely his own doing.
He added that he'd been holding that line. Now he isn't, and the reason he gives is Google.
Google's AI work, in his telling, adds up to a shift in how its products operate, away from sending people elsewhere and toward answering them in place. That framing is the cleanest summary of the problem any executive has offered this year. The distributor stopped distributing.
What Analysts Said About the Login Test
Wall Street didn't rally around the plan. Several firms cut their ratings on the stock after the call.
Citizens offered the sharpest framing. The firm said the search change highlights the problem of selling content to Google in the first place, and that the uncertainty a login requirement creates around user growth puts more pressure on monetizing the users Reddit does have.
Read those two points together and you get the bind. Licensing content to Google brings in money that doesn't scale with traffic. Advertising brings in money that does, but only while the traffic arrives.
What This Means for Every Site That Lives on Search
Reddit isn't a special case. It's an early one. Google spent years tuning search to surface forum posts and first-person answers, a shift that sent a large volume of readers to Reddit and helped the company grow into a public business.
Then Google started answering the question itself. The same pages that benefited from the referral economy now compete with a summary that appears before them.
Licensing deals soften the blow a little. Reddit has an arrangement that lets Google use its content for AI training, and that revenue is real. It just doesn't replace a referral stream that was worth more, because an ad impression on a live page compounds while a licensing check arrives once.
Every publisher with a search-dependent audience is running the same math this quarter. Some will build walls. Some will push newsletters and apps. Some will accept smaller traffic and chase higher rates per visit.
What to Watch in the Next Two Quarters
So what would settle the argument? Three things. The first is whether the October referral decline holds through the holiday quarter, when ad budgets peak. The second is what Reddit actually shows a logged-out visitor once the test goes live abroad. The third is whether the licensing line grows fast enough to matter on a $1 billion-plus quarterly revenue base.
Reddit bet its growth on being the open front door of the internet. That door is closing, and the company is the one closing it. Whether readers follow it inside is the only question left.
