Reddit will require login as AI search cuts traffic

Reddit has announced a shift toward a logged-in experience, requiring users to sign in rather than browse openly. The company is rethinking its long-standing open-web approach as AI-driven search changes how people find information online and as search traffic declines. The move reflects a broader tension between public content and the businesses that depend on it. For years, Reddit benefited from being widely accessible. Search engines could index its discussions, and visitors could land on threads from outside the site. That openness helped Reddit become a major destination for niche advice, product research and community knowledge. But AI search engines and answer tools can now summarize or reuse public content without necessarily sending clicks back to the source. For a platform built on user-generated discussion, that can weaken the relationship between content and audience. Requiring login may give Reddit more control over its community and data. It could help the company track engagement, personalize experiences and negotiate stronger terms with AI companies and search partners. A signed-in audience may also be more valuable to advertisers because Reddit can connect activity across sessions. But the change carries risks. Casual visitors may leave rather than create accounts, reducing the serendipity that made Reddit useful to newcomers. Communities may worry about privacy and how login requirements affect anonymity. Reddit is not alone in confronting the shift. Publishers, forums and social platforms are all trying to protect their businesses as AI answers absorb attention. The company's decision could become a test case: whether login walls preserve value or shrink the open-web reach that made a platform culturally important. Reddit will need to balance its community ethos with commercial survival. The outcome will influence how other platforms treat public content in an AI-mediated search landscape.
