Reddit Says Google's AI Mode "Does Not Drive Traffic" as Search Referrals Fall by 1 Million a Week

Reddit reported its strongest quarter of the year on 29 October 2026 — and its shares fell about 18% in after-hours trading anyway. Revenue rose 53% to $895 million. Chief executive Steve Huffman told investors that search referrals had fallen by more than 1 million a week on average during October, and that Google's AI-powered search features were part of the reason. "The reality is, AI Mode does not drive traffic," he said on the earnings call. "Not for us, and not to anybody, as far as I know."

That sentence matters beyond Reddit. For two decades, Google search was the front door of the web: a site ranked well, people clicked, and the clicks became readers and advertising revenue. Reddit is now saying that the front door is closing — at least for logged-out visitors arriving from search. This article keeps three things separate: what Reddit's own documents say, what Huffman said on the call, and what is still only Reddit's claim about its own traffic.

1. A strong quarter, and a warning attached to it

The numbers in Reddit's own results release, for the quarter ended 30 September 2026, were strong. Total revenue reached $895 million, up 53% year over year. Advertising revenue rose 54% to $847 million, and other revenue — mostly data licensing — rose 35% to $48 million. Net income was $283 million, and diluted earnings per share were $1.40, up 75% from a year earlier. Daily active uniques, Reddit's DAUq measure, grew 12% to 130.3 million.

Two figures sat uneasily beside that growth. In the United States, DAUq fell 2% to 50.7 million — the first decline since Reddit went public in 2024, according to Reuters. And guidance for the fourth quarter came in below expectations: revenue of $1.00 billion to $1.03 billion, against an expected $1.05 billion, according to LSEG estimates compiled by CNBC, with adjusted EBITDA guided at $480 million to $510 million. Shares fell about 18% in after-hours trading, as reported by CNBC and Reuters. Investors were pricing the warning about the next quarter, not the one just reported.

2. The traffic warning, in Reddit's own words

Reddit's shareholder letter said search referral traffic was "down meaningfully in Q3, with the decline accelerating later in the quarter," according to reports quoting the letter, which was filed with the US Securities and Exchange Commission. "During October, we have seen that search traffic has dropped by more than 1 million referrals on average per week," the letter said. Reddit warned that if October's pace continued, total DAUq could fall in the fourth quarter "by a low-double-digit percentage from our current base of 130 million."

One distinction matters here. A reading of the shareholder letter reported by PPC Land noted that the letter itself does not name a search engine and does not attribute the decline to any particular cause. The attribution to Google's AI features came from Huffman on the earnings call — not from the letter. Hold the two at different weights: the referral numbers are Reddit's disclosed figures; the cause is Reddit's interpretation of them.

3. What Huffman blamed: AI answers that end the search

On the call, Huffman was blunt about the mechanism. Google's AI Overviews and AI Mode, he said, have "evolved a lot" and now, "at a minimum," push "everyone down the search page," as reported by The Verge. Where a search once returned a list of links, an AI answer increasingly returns the answer itself — and the click never happens. "It used to be a traffic driver, now it's not," Huffman said of Google, in remarks reported by The Verge and Engadget. He added a second factor: Reddit believes its machine-translated content is being ranked lower in search results, primarily outside the United States, according to The Verge's report of the call.

Huffman also argued that demand for Reddit's content had not fallen. "Google is crawling us as hard as ever, so the demand hasn't changed from their point of view either," he said on the call, as reported by Reuters. In the US, he said, "Reddit" remains among the most-searched terms on Google. Google had not publicly responded to Reddit's claim at the time of writing, according to a 30 October review of the coverage.

4. Reddit's answer: make people log in

Reddit's response is the biggest change to how its site works in its history. Huffman wrote in the shareholder letter that a "key piece of work to retain new audiences is shifting Reddit to a logged-in-only experience," as quoted by Engadget. Testing begins in the fourth quarter in select markets outside the US, with no wider timetable given and no markets named. The company has not settled what logged-out visitors will see: Huffman said Reddit still had to find "the right boundary" for when a visitor hits a hard prompt to log in.

The login requirement is not only about search traffic. In his own post about the change, Huffman gave four reasons: a better experience for logged-in users, a stronger advertising business, safety regulation, and protecting Reddit's data from scrapers, as reported by Platformer. Logged-in and app users already account for more than 80% of Reddit's monetization, according to chief operating officer Jen Wong on the call. Reddit licenses its data to OpenAI and Google, and is suing Anthropic, Perplexity AI and three data-scraping companies, accusing them of collecting it illegally, according to Reuters.

5. Why publishers far smaller than Reddit are watching

Reddit is an unusually large and public test case, but the mechanism Huffman described is not unique to it. When a search engine answers the question on its own page, the sites that supplied the answer get fewer visits. A 2025 Pew Research study of US users, cited in coverage of Reddit's warning, found people clicked a result on 8% of Google visits that showed an AI summary, against 15% of visits without one. That is one study, from one country — it shows the direction, not the size, of the effect for any particular site. No evidence in Reddit's disclosures says smaller publishers are losing traffic at Reddit's rate, and this article makes no such claim. INORYVA's own baseline is far too small to draw conclusions from: 30 active users and 348 views across 22–28 October 2026, according to its Google Analytics property.

6. What to watch next

Three questions will decide whether this becomes a turning point or a bad quarter. First, the login test: how many visitors convert to accounts, and how much reach Reddit loses, before any wider rollout. Second, the fourth-quarter user number: Reddit has said DAUq could fall by a low-double-digit percentage if October's referral pace continues — a forecast tied to a condition, not a result. Third, Google's answer, or lack of one. Until Google responds directly, or other large publishers publish their own referral numbers, the honest summary stays narrow: one large platform measured a steep fall in search referrals, blamed AI search features for part of it, and is rebuilding its front door around logged-in users.

Key Takeaways

Reddit reported Q3 2026 revenue of $895 million, up 53%, with EPS of $1.40 — yet shares fell about 18% after hours on the traffic warning and weaker Q4 guidance ($1.00–$1.03 billion).
Reddit's letter said search referrals fell "meaningfully" in Q3 and by more than 1 million a week on average in October; if that pace continues, DAUq could fall by a low-double-digit percentage in Q4 from 130 million.
The attribution to Google's AI Mode and AI Overviews came from Huffman on the earnings call, not from the letter, which did not name a search engine. Treat the numbers as disclosed figures and the cause as Reddit's interpretation.
Huffman: "The reality is, AI Mode does not drive traffic, not for us and not to anybody, as far as I know." He also cited lower rankings for machine-translated content outside the US, while saying Google still crawls Reddit "as hard as ever."
Reddit will test a primarily logged-in experience in select non-US markets in Q4, citing ad targeting, engagement, data protection and regulation — not search traffic alone. Logged-in/app users drive over 80% of monetization.
No Google response to Reddit's claim had been seen at writing. This is Reddit's account of its own traffic, not proof of a web-wide effect.

Reddit spent twenty years as the open web's front porch: anyone could arrive from a search, read a thread, and leave. Its answer to falling search referrals is to put a door on that porch and ask visitors to sign in. Whether that saves the business or shrinks it will be visible in the next two quarters — in the login test, in the daily user count, and in whether any other publisher can put a number on the same decline. For now, the most useful thing any publisher can do is watch its own search referrals, week by week, and stop assuming the clicks will come back on their own.
