Shares of Reddit cratered after the company delivered a strong third quarter but spooked investors with a cautionary outlook that strikes at the heart of its growth story. RDDT dived 18% in after-hours trading on October 29 , settling around $113.30, after Q4 revenue guidance of $1.00 billion to $1.03 billion fell short of the roughly $1.05 billion analysts expected . The miss looks small on paper. The reason behind it does not.
• A Beat That Nobody Wanted to Celebrate
Reddit posted Q3 revenue of $895 million, up 53% year over year, with net income of $283 million, or $1.40 per diluted share — a 75% jump . Both figures topped consensus estimates of $886 million and $1.31, respectively . But the stock sold off because Wall Street prices forward momentum, not backward victories. The guidance gap, though just 2% below estimates at the midpoint, signals a decelerating revenue growth rate — from 53% in Q3 to roughly 38%–42% in Q4 .
• Google's AI Is Eating Reddit's Front Door
Search referral traffic declined meaningfully in Q3 and accelerated into Q4, with October seeing a drop of more than 1 million referrals per week. The pressure stems from Google's rollout of AI Overviews and AI Mode, which answer queries directly instead of sending users to Reddit . This matters enormously: search has been Reddit's cheapest source of new and returning visitors. Management warned that if the trend persists, daily active users could fall by a "low double-digit" percentage in Q4 from the current 130 million .
• The U.S. Audience Is Already Shrinking
Global daily active uniques hit 130.3 million, growing 12% year over year, but U.S. users — Reddit's most valuable ad audience — declined 2% . Internationally, Reddit spent more on marketing to offset lost search traffic , a strategy that trades free organic reach for paid acquisition — eroding the margin advantage that made the growth story appealing.
• A Logged-In Pivot Is a High-Stakes Gamble
Reddit plans to begin testing a logged-in-only experience in select international markets in Q4 . The logic: logged-in users are worth far more to advertisers. Management noted logged-in and app users account for over 80% of total ad revenue . But forcing logins risks accelerating the user decline Reddit is already warning about — precisely when it can least afford it. Citizens downgraded the stock, citing declining user growth and reduced Google referrals .
Reddit's $3 billion trailing-twelve-month revenue run and longer-term $5 billion revenue target now hinge on whether the platform can replace Google's free traffic pipeline with its own direct audience — a transformation no major content platform has pulled off quickly or cheaply.
