Reddit (NYSE: RDDT) did the hard part. It beat expectations. Revenue up 53%, earnings per share of $1.40 versus the $1.36 consensus, advertising humming along. And yet the stock is getting taken to the woodshed Friday morning, down nearly 19% premarket to $105.01, a fresh 52-week low.

The culprit isn't the quarter that just ended. It's the quarter that hasn't happened yet, and a search traffic trend that has management openly worried.

The Google Problem

Reddit forecast fourth-quarter revenue of $1.00 billion to $1.03 billion. Analysts were looking for $1.046 billion. That's a miss, and in a market that grades on a curve, a miss is a miss.

But the bigger story is where the eyeballs are coming from. CEO Steve Huffman said search traffic declined by more than 1 million referrals on average per week during October. If that trend holds, daily active uniques (DAUs) could fall by a low-double-digit percentage in the fourth quarter from the current level of 130 million.

Management cited Google's AI Overviews and AI Mode, along with lower rankings for machine-translated content, as possible factors behind the decline. In other words, Google is answering questions itself, and Reddit is feeling the pinch.

Huffman was careful to note that the traffic weakness does not reflect softer consumer demand. Reddit, he pointed out, remains a top Google search term. People still want the content. They're just finding it differently, or not at all.

The Quarter That Was Actually Good

Let's not lose the plot here. The third quarter was strong. Revenue came in at $895 million, up 53% year over year and above the $878.02 million analyst estimate. Earnings per share hit $1.40, beating the $1.36 consensus.

Advertising revenue increased 54% to $847 million, while other revenue grew 35% to $48 million. Stronger pricing, impressions and conversions drove the ad growth. Ad clicks rose more than 50%, while conversion volume more than tripled.

Scaled advertising revenue increased over 80%, and mid-market active advertisers grew more than 50%. Shopping and app-install campaigns each expanded more than 95%.

U.S. revenue rose 50%, international revenue climbed 67%, and average revenue per unique user increased 36% to $6.87.

Reddit also repurchased approximately $100 million of shares during the quarter at an average price slightly below $150, with $660 million remaining under its buyback authorization. The company ended the quarter with $3.03 billion in cash and marketable securities, while capital expenditure totaled just $1.2 million. That's a remarkably asset-light operation.

Ads, AI And The Product Pipeline

Reddit MAX adoption more than tripled sequentially after entering public beta. Video advertising revenue more than doubled, while shopping tools expanded to support up to 20 million products.

The company also expanded its machine-learning capabilities, lead-generation tools and integrations with advertising partners. Revenue from its Ads API ecosystem increased more than 45% quarter over quarter.

On the engagement side, Reddit is prioritizing direct engagement through improved personalization, feed performance and app conversion. First-week retention among new app users increased more than 50% year over year, while video engagement also improved.

The platform added 1 billion posts and comments in the third quarter, while AI-powered moderation efforts helped reduce the median enforcement response time from 58 hours to five seconds during 2026. That's not a typo. Five seconds.

Logging In, Locking Down

Reddit plans to test a primarily logged-in experience in selected international markets during the fourth quarter of 2026. The shift is intended to improve engagement and ad targeting while limiting data scraping, which Huffman said occurs largely through logged-out access. Logged-in and app users account for more than 80% of monetization.

Reddit said it remains open to data-licensing agreements that support its long-term strategy and provide fair value, while also exploring the return of an in-app Incognito Mode to improve retention.

The company is also shifting U.S. marketing toward app installs and brand campaigns, as web campaigns have delivered weaker retention. App-install campaigns have achieved retention rates comparable to organic users, while international web marketing is increasing to help offset declining search referrals.

The Road To $5 Billion

Reddit's trailing 12-month revenue has surpassed $3 billion, according to its COO. Management sees further opportunities to grow engagement, advertising revenue and average revenue per user as it works toward its longer-term $5 billion revenue target.

Huffman also said Reddit has significantly reduced the time required to train and deploy new AI models. Meanwhile, the CFO noted that headcount increased approximately 3% sequentially and 12% year over year.

So here's the tension. The business is growing fast, the ad machine is working, and the balance sheet is fortress-like. But Reddit's user growth has leaned heavily on Google search referrals, and Google is increasingly in the business of answering questions without sending anyone anywhere. That's a structural headwind, not a one-quarter blip, and investors are pricing it in accordingly.
