Reddit says Google's AI Mode sends it no traffic — and will test locking casual browsing behind a login

For twenty years, anyone could wander into Reddit from a search result, read a thread, and leave without ever creating an account. That open door is now closing. Alongside its third-quarter results on October 29, Reddit said it will test an experience in which most browsing requires signing in, starting in selected markets outside the United States before the end of the year.

The reason, in chief executive Steve Huffman's telling, is what AI search has done to the flow of visitors that built Reddit's audience. Search referrals fell by more than a million a week on average in October, he said on the earnings call, and he dismissed Google's AI Mode as a source of visits altogether. The market heard the warning louder than the results: Reddit's shares fell 18% in extended trading.

A strong quarter, and a warning attached#

Nothing about the quarter itself looked like a company in trouble. Revenue reached $895 million, up 53% on a year earlier and ahead of the roughly $878 million analysts had expected. Net income was $283 million. Guidance for the current quarter put revenue at $1.00 billion to $1.03 billion, with adjusted earnings before interest, taxes, depreciation and amortisation of $480 million to $510 million, just below the $512.2 million analysts had pencilled in.

The user numbers told the other half of the story. Global daily active uniques grew 12% year on year to 130.3 million, but were flat against the previous quarter. In the United States, the company's largest market, daily uniques fell 2% year on year to 50.7 million, down from 53.2 million in the second quarter — the first US decline since Reddit went public in 2024. Finance chief Drew Vollero added that Reddit had crossed $3 billion in trailing twelve-month revenue, with $5 billion as its next internal target. The business is growing; the audience pipeline feeding it is narrowing.

The leak is in logged-out America#

The split inside the US numbers points at the mechanism. Logged-out American users fell 4% year on year, while logged-in Americans rose 1%. The people disappearing are the anonymous ones — exactly the visitors most exposed to a search page that now answers questions itself. When an AI summary settles a query on the results page, there is no click left to send, and no thread visit to count.

That attribution deserves care. The referral decline is Reddit's own measurement, and the claim that AI search caused it is Huffman's. His supporting point was that Google still crawls Reddit as heavily as ever, so appetite for its content has not faded — only the clickthrough has. It is a plausible account of one platform's traffic, not yet a measured effect across the web, and Google's side of the argument was not part of the reporting. Analysts also flagged the other side of the trade: as one put it, requiring a login adds friction for casual visitors, the very group Reddit is already losing.

Why a login is worth more to Reddit than a visitor#

Reddit's arithmetic for the swap is straightforward. Logged-in and app users already account for more than 80% of what the company earns, so the anonymous minority contributes reach far out of proportion to revenue. A signed-in user can be served personalised feeds and better-targeted advertising, and can be counted, retained and sold to advertisers as a known audience rather than a passing click.

The second motive is the archive itself. Reddit's decades of human discussion are prized training and research material, and the company now licenses that corpus to OpenAI and Google under deals it says carry guardrails for users and the business. At the same time it has sued Anthropic, Perplexity and three data-scraping firms over unauthorised collection. A login wall does not stop a determined scraper, but it raises the cost of bulk harvesting and makes every account a traceable actor. Reach, in this framing, was subsidising the very extraction Reddit now charges for.

What the test has to prove#

The test itself is deliberately contained: selected markets outside the US, during the fourth quarter, with no date announced for a wider rollout. What it must measure is conversion against attrition — how many casual visitors create accounts, how many simply bounce, and whether the signed-in audience that remains is engaged and valuable enough to make up for the smaller front door.

Huffman's warning about the fourth quarter should be read as a scenario, not a forecast. He said daily uniques could fall by a low double-digit percentage from about 130 million if October's referral pace continues. If the login test converts well, that scenario softens; if visitors bounce instead, Reddit will have accelerated the very decline it is trying to manage, while still guiding to revenue above $1 billion for the quarter. Either way, the fourth-quarter user print becomes the number that judges the strategy.

What to watch#

Four things matter from here. First, conversion in the test markets: the share of visitors who sign in, and how long they stay. Second, the fourth-quarter user count, which will show whether the low-double-digit scenario materialised. Third, whether other large publishers publish their own referral numbers, turning one company's complaint into an industry measurement. And fourth, the scraping lawsuits, which will decide how much legal backing a login wall actually has.

Reddit grew up as a place you could visit without introducing yourself. Its next chapter starts by asking everyone at the door who they are — and betting that a smaller, identified community is worth more than the open crowd it replaces.
