Reddit will begin requiring visitors to sign in before browsing its content, testing the requirement in select markets outside the United States during the fourth quarter of 2026. The company has not announced a schedule for extending the policy to other markets, nor has it disclosed what logged-out users will see. For a platform that has historically been browsable without an account, it is a structural change to how new readers arrive.

Why Reddit wants users signed in

The rationale is laid out in Reddit's Q3 2026 shareholder letter. Logged-in and app users account for more than 80% of monetization and the bulk of engagement. Reddit CEO Steve Huffman told The Verge that requiring accounts could improve personalization, advertising, and protection against unauthorized scraping.

The app's incognito mode is also returning, meaning users will need to sign in but will not have to reveal their real-world identities.

There is a trade-off, however. As Luke Stillman of Madison and Wall told Reuters: “Requiring users to log in creates another barrier to engagement, particularly for casual users.”

The numbers behind the decision

Reddit's revenue kept growing even as traffic declined. Third-quarter revenue rose 53% to $895 million, beating analyst estimates of $878.4 million. Average daily active unique users worldwide stood at 130.3 million, including 79.6 million outside the United States, while daily US users fell 2% to 50.7 million.

Those proportions give the test markets outsized weight: the 79.6 million daily users outside the United States make up the majority of Reddit's global audience — and that is where the sign-in wall will first go up.

Search traffic weakened further in October. Reddit's search referrals dropped by more than 1 million per week on average, with logged-out users bearing the brunt of the decline. If the trend continues, Reddit warned that daily users could fall by a low double-digit percentage in Q4 from its current base of roughly 130 million — a figure the company stressed remains a forecast.

The warning unsettled investors: Reddit's shares dropped 18% during evening trading, according to Reuters.

What the AI search data actually shows

Huffman blamed Google's AI Mode, saying it does not send visitors to Reddit or other websites. Google, for its part, says AI Mode had surpassed one billion monthly users by May. More usage, however, does not necessarily translate into more outbound clicks.

Pew Research found that Google users clicked a traditional result in 8% of visits featuring AI summaries, versus 15% without them; only 1% clicked links inside the summaries themselves. Similarweb likewise found that monthly referrals from generative AI platforms held at roughly 240 million–280 million through January 2026, even as monthly AI visits approached 1.5 billion. Neither dataset is Reddit-specific, but together they describe the click environment in which Reddit's search referrals are eroding.

The impact on Reddit is not entirely negative. An Emory–Washington University study (published on arXiv) linked AI Overviews to 12% more daily comments in safe-for-work communities, though those gains largely disappeared from opinion and advice discussions after AI Mode arrived. Cryptopolitan flagged the search-referral risk in May 2025.

Licensed data versus lost casual readers

Reddit licenses its content to Google and OpenAI while suing companies it accuses of unauthorized scraping. Google's 2024 partnership gives it structured access through Reddit's Data API, although Google says its use of publicly crawlable material is unchanged.

The first login tests are headed to selected overseas markets, even as Reddit's international daily audience grew 24% year over year. Accounts could deepen engagement and sharpen ad targeting — but if casual visitors walk away, Reddit's reach could suffer.

Reddit expects $1.00 billion–$1.03 billion in Q4 revenue and $480 million–$510 million in adjusted EBITDA. That outlook covers the same quarter as the first sign-in tests — and the same quarter in which Reddit has warned daily users could fall by a low double-digit percentage — making the Q4 report the first public checkpoint for both the referral decline and the login experiments. Expansion beyond the initial test markets remains unscheduled.
