Reddit Shares Drop 29% as It Blames Google's AI Search for 1M Fewer Weekly Referrals

TL;DR

Reddit posted a strong third quarter: $895 million in revenue, up 53%, and $283 million in net income. Its Q3 2026 shareholder letter then said search referral traffic was "down meaningfully," that referrals fell by more than 1 million per week on average in October, and that total daily users could fall by a low-double-digit percentage in Q4. On the earnings call, CEO Steve Huffman named Google's AI Mode and AI Overviews as the main suspects, and Reddit will start testing a logged-in-only site in Q4. The stock fell about 29% on Friday, October 30.

What Reddit actually reported

Revenue was $895 million, up 53% year over year. Gross margin was 91.5%, net margin was 32%, and free cash flow was $363 million. Q4 revenue guidance is $1.00 billion to $1.03 billion.

Global daily active uniques (DAUq) reached 130.3 million, up 12% from a year earlier, but all of that growth came from outside the U.S. U.S. DAUq fell 2% to 50.7 million. U.S. logged-out users, the people who arrive from a search result, read a thread and leave, fell 4% to 27.3 million.

Logged-in users barely moved. U.S. logged-in DAUq went from 23.1 million to 23.4 million.

The October number that moved the stock

The warning about the current quarter got the attention. Reddit wrote that the search decline accelerated late in the quarter and continued into Q4:

"During October, we have seen that search traffic has dropped by more than 1 million referrals on average per week. If this rate of decline continues, current trends would suggest that total DAUqs could fall in Q4, by a low-double-digit percentage from our current base of 130 million DAUqs."

A low-double-digit drop from 130 million means losing at least 13 million daily users in one quarter. Reddit did not break the decline out by search engine and did not give a weekly baseline. So you know the direction and rough size of the drop, but not the exact rate.

The stock was already sliding before the report. RDDT closed at $155.65 on October 20 and $129.60 on October 29. On October 30 it traded as low as $89.28 and sat near $92 at the close, about 41% below where it stood ten days earlier.

Huffman's diagnosis: AI answers sit on top of the links

On the call, Huffman said the biggest part of Reddit's working hypothesis is Google's AI Overviews and AI Mode, which Google is expanding in the U.S. and other markets. At minimum, he said, those features push the other results down the page. A second, smaller factor is machine-translated Reddit content that Reddit believes Google now ranks lower, mostly outside the U.S.

His line on AI Mode, as reported by Decrypt and Search Engine Journal:

"The AI mode does not drive traffic, not for us and not to anybody as far as I know."

He added that Google is "crawling us as hard as ever" and that demand for Reddit has not changed: "Reddit" is still one of the most-searched words on Google. Huffman said he does not think this is a temporary algorithm swing, though he admitted Reddit has little visibility into Google's ranking.

Picture a bakery whose best customers used to walk past a bigger shop that pointed at it. Now that shop hands out free samples of the bakery's bread at the door, and the line outside the bakery gets shorter every week.

The response: a login wall

Reddit's answer is to stop relying on drive-by readers. The letter says Reddit is "shifting Reddit to a logged-in-only experience," starting with full tests "in select markets outside the U.S." in Q4. Those results "will inform an optimized version of logged-in-only Reddit globally."

The company gives several reasons: better relevance for users, better ad-targeting signals, protection for "Reddit's extremely valuable corpus of data," and easier compliance with new regulations. Huffman said on the call that most scraping happens through logged-out access. He also said some content will still show before a hard login prompt and shared links will keep working, and that Reddit will probably trade reach for engagement. "This is a test, but we are going to make this transition," he said, per Search Engine Journal.

The letter says logged-in and app users make up the vast majority of engagement and over 80% of monetization, and both grew sequentially in Q3. Logged-out visitors are the larger group (76.8 million of 130.3 million global DAUq) but earn much less per head. Reddit is betting that losing some of them to a login prompt costs less than giving them, and every scraper with them, free access.

The data-licensing angle

Reddit already licenses its content to Google and OpenAI for AI training. Search Engine Journal reports that management said talks with both are ongoing with no update, and that not doing a deal is one possible outcome. A logged-in-only Reddit is also a harder target for anyone who wants that corpus without paying for it.

COO Jen Wong said Reddit is "pretty skeptical of GEO" (generative engine optimization) and does not include it in advertiser partnerships. Reddit is also raising international marketing spend to make up for lost search reach. That means paying for visitors Google used to send for free.

Why this matters if you run a site

Reddit was the clearest winner of the old Google. Its threads ranked for everything from "best budget monitor" to "is this mole normal." If the most-favored forum on the web says AI answers are costing it more than a million referrals a week, a smaller site with less brand demand is probably getting hit harder and may not have the data to prove it.

You can copy Reddit's response at any size: treat search as a declining acquisition channel, move value behind an account, and measure logged-in users separately from total traffic. CFO Drew Vollero said Reddit will keep reporting logged-in and logged-out DAUq by geography, reversing an earlier plan to phase that breakdown out this year. Investors apparently want the numbers that show how big the problem is.

Caveats

• The AI Overviews and AI Mode explanation is Reddit's working hypothesis. The company did not say how much of the decline it attributes to each cause.
• The Q4 user decline is conditional: it applies "if this rate of decline continues."
• The CEO quotes come from the earnings call as reported by Decrypt and Search Engine Journal. Reddit's investor site blocks automated access, so we could not check them against an official transcript.
• Friday's price figures are from market data at the close. Decrypt reported a 30.44% drop to $90.15 at the time of its story.

Key Takeaways

• Reddit's Q3 2026 revenue rose 53% to $895 million, but U.S. DAUq fell 2% and U.S. logged-out users fell 4%.
• Search referrals dropped by more than 1 million a week on average in October, and Reddit warned total DAUq could fall by a low-double-digit percentage in Q4.
• Huffman named Google's AI Overviews and AI Mode as the biggest part of the problem and said AI Mode "does not drive traffic."
• Reddit will test a logged-in-only experience in select non-U.S. markets in Q4 and plans to roll out a version globally.
• Shares fell about 29% on October 30, roughly 41% below the October 20 close.
• If you depend on Google traffic, track logged-in users and direct visits separately, because those are the numbers that hold up.
