Reddit's Google Lifeline Runs Dry as AI Search Starves the Open Web

Reddit's Google Lifeline Runs Dry as AI Search Starves the Open Web

A 30% crash on a revenue beat tells the whole story

Reddit just posted one of its best quarters on paper — and suffered the worst stock rout in its history. Shares plunged about 30% on October 30, the day after third-quarter results, after the company admitted that search referral traffic was "down meaningfully in Q3" with the decline accelerating late in the quarter. "People still want Reddit. It's just Google is not sending them to Reddit the way they used to," CEO Steve Huffman said on the earnings call. Premarket trading on Friday had already shown a drop of more than 23% as investors digested weak fourth-quarter guidance.

Strong monetization, stalling audience growth

The headline numbers were genuinely strong: revenue of $895 million, up 53% year over year; net income of $283 million; diluted EPS of $1.40, up more than 70%; adjusted EBITDA of $402 million. Advertising revenue rose 54% to $847 million, with average revenue per user up 36% to $6.87, beating the $6.50 consensus. But the audience engine sputtered. Daily active uniques reached 130.3 million, up 12% year over year yet below the 133.7 million Wall Street expected. U.S. daily actives fell 2% to 50.7 million versus 53.5 million expected, with international growth of 24% masking the domestic slide. Weekly actives of 515.2 million, up 16%, were little comfort.

AI Overviews answer the question so nobody clicks through

The mechanism is no mystery. Since Google rolled out AI Overviews in 2024, an AI-generated summary sits atop search results, and publishers have watched clicks evaporate. A Pew Research Center study of more than 68,000 searches by 900 U.S. users found that only 1% ended with a click on a source cited in an AI Overview. Reddit said the damage fell hardest on logged-out and web traffic, with knock-on effects on logged-in and app reengagement. In October, search referrals fell by more than 1 million per week on average, and the company warned daily actives could drop by a low-double-digit percentage from the 130 million base if the trend holds.

Reddit's answer: lock the doors and test logins

Reddit's response is the most drastic in its 21-year history: a move toward a logged-in-only experience. Testing begins in the fourth quarter in select markets outside the U.S., with the company still deciding how much logged-out visitors arriving via search or shared links can see. Huffman framed it as better for user experience, advertising, and data protection against unauthorized scraping. The company also rebuilt its app's incognito mode. But the symbolism is stark: a site synonymous with the open internet now believes openness is a liability, and JPMorgan analysts tied the traffic drop to both AI search expansion and ranking changes for machine-translated content.

Google is bleeding too, with $500 billion gone in a day

Cutting off the rest of the web has not enriched Google. Alphabet's search revenue growth slid from 19% in Q1 to 17% in Q2 to 12% in Q3, with search and related revenue of about $63.35 billion missing the $64.96 billion consensus. Chief Business Officer Philipp Schindler attributed part of the slowdown to lower monetization in AI Mode, even as query growth ran at its fastest in five years. Alphabet shares suffered their worst day ever, shedding more than $500 billion in market value. Analysts at UBS said search cannibalization fears were "right back to the forefront."

A crossroads for everyone who lived off Google traffic

Reddit is the loudest casualty, but publishers across the web report the same starvation diet: visibility inside AI answers without the clicks that pay the bills. The irony is sharp — in February 2024 Reddit signed a reported $60-million-a-year data licensing deal giving Google access to its discussions for AI training, plus a later partnership with OpenAI. Now the AI models it helped feed are intercepting its readers. With fourth-quarter revenue guided at $1.00 billion to $1.03 billion, or 38% to 42% growth, below consensus, the question hanging over Reddit — and every publisher that grew up on Google referrals — is what comes after search: walled gardens, direct audiences, or a new bargain with the AI gatekeepers.
