Reddit has said it will put most of its content behind an account. The announcement is less interesting than the arithmetic behind it — and the arithmetic is mixed.

In the third quarter Reddit averaged 130.3 million daily active users. Of those, 76.8 million were not logged in. At the same time, app users and logged-in users account for more than 80 percent of monetization. The majority of readers are precisely the group that is hard to target with ads and that the company blames for most unauthorized access: scraping.

The plan is to convert the majority into the minority. Tests start outside the US; which markets, Reddit will not say. The homepage, shared links and search results are supposed to stay readable logged out, a revised incognito mode is meant to allow reading without the account noticing, and nobody has to reveal their identity to register — "honestly, we don't want to know," CEO Steve Huffman wrote.

The trap is in the timing. Reddit's search traffic fell sharply in the third quarter, especially among logged-out users; in October it received more than 1 million fewer search referrals per week on average. At the same time the company is switching off RSS feeds on 13 November and the public API by March 2027. Anyone arriving today via a search engine or an aggregator is exactly the casual reader a login wall is most likely to lose — to AI answers, to summaries, to nothing at all.

The business model is a bet on three revenue streams: advertising that a login makes easier to target; data licences to Google and OpenAI; and litigation against Anthropic (case CGC-25-625892) and Perplexity (1:25-cv-08736) over scraping. Forcing a login is meant to make scraping more expensive by tying it to accounts. Whether that works depends on AI crawlers obeying rules — logged-out HTML was never the only way in.

Three things to watch: whether the login wall erodes search visibility rather than protecting it; whether Reddit really keeps the homepage and shared links open once ad targets come under pressure; and whether regulators read the coupling of account and access as a consent problem. Reddit is renegotiating the open web's bargain — read for free, get indexed, sell ads. The numbers suggest both sides of that bargain are already weaker than the announcement sounds.
