Reddit Plunges 29% on User Decline and Login Mandate Despite Earnings Beat

Key points

• Reddit stock fell 29% to $91.67 after Q3 results, despite beating revenue and EPS estimates.
• The drop was triggered by a warning that daily active users could fall by a low double-digit percentage in Q4.
• Reddit announced plans to require logins for forum access, starting with tests in international markets in Q4.
• Roblox shares fell 17% as daily active users dropped 9% year-over-year to 138 million, despite beating loss and revenue expectations.
• Pinterest shares fell 3% after reporting revenue of $1.17 billion, below the expected $1.21 billion.
• The Global X Social Media ETF (SOCL) fell nearly 3%, with Reddit comprising about 8.46% of its assets.

Background

This follows earlier reports that Reddit is ending its 21-year open browsing policy to protect content from AI scraping and improve ad targeting. The move comes amid a broader market sell-off on October 30, 2026, where the Nasdaq fell 3.3% and the S&P 500 dropped 2.2% due to AI spending fears and weak tech earnings. Reddit’s stock had already fallen 44% year-to-date before this latest drop, reflecting mounting investor concerns over slowing U.S. user growth.

How outlets are covering it

Yahoo Finance emphasizes the negative impact of Reddit’s login mandate and weak user forecasts on its stock, noting the 29% drop. 24/7 Wall St. highlights that Reddit’s Q3 earnings actually beat expectations, with revenue growing 53% and EPS at $1.40, but argues the selloff was driven by the warning of over 1 million weekly search referral drops. 24/7 Wall St. also notes that while broad index funds like VOO and IVV have minimal exposure to Reddit, thematic funds like SOCL are heavily impacted, with Reddit making up about 8.46% of its assets. Both outlets agree that AI-driven traffic losses are a central concern, but 24/7 Wall St. places more emphasis on the structural impact on ETFs and the divergence between strong earnings and weak stock performance.

Why it matters

The selloff in Reddit, Roblox, and Pinterest signals growing investor skepticism about the long-term viability of social media platforms in the face of AI-driven traffic shifts. The move to require logins could reshape user engagement and ad revenue models, while the heavy exposure in thematic ETFs like SOCL means the impact extends beyond individual stock holders to broader retirement portfolios. This event underscores the increasing importance of user retention and data monetization in the digital economy, particularly as AI features continue to disrupt traditional search and referral traffic.

What to watch

Investors will watch Reddit’s Q4 user numbers and the results of its login tests in international markets. Management has indicated it will trade reach for engagement, with logged-in and app users generating over 80% of monetization. The next portfolio disclosures from SOCL and S&P 500 trackers will show how Reddit’s weight has changed. Broader market sentiment will also depend on how other tech companies respond to AI-driven traffic and spending pressures.
