Reddit plunges as Google AI search squeezes traffic

By Thomson Reuters Oct 30, 2026 | 6:40 AM

Oct 30 (Reuters) – Shares of Reddit tumbled 23% in premarket trading on Friday after it warned Google’s growing use of AI in search was hurting referral traffic ​and could shrink its user base, offering fresh evidence ‌of AI-driven disruption.

Pinterest also fell 7.28% after forecasting fourth-quarter revenue below Wall Street estimates, as a pullback by cross-border sellers in Europe weighed on its outlook.

Here are more details:

• Reddit’s warning highlights how Google’s shift toward ‌AI-powered ​search, which can answer queries directly, ⁠is disrupting the flow ⁠of traffic to websites that have traditionally relied on the search engine for users

• Total daily active unique visitors could fall by a low double-digit percentage in the fourth quarter ​from about 130 million if referral traffic continues to fall, Reddit said

• JPMorgan analysts said the expansion of Google’s ⁠AI Overviews and AI Mode, along ⁠with changes to how machine-translated content is ranked, ​has pushed search traffic down

• A reset in expectations is appropriate ​and the near-term outlook is increasingly clouded, said Piper ‌Sandler analysts

• Meanwhile, Reddit said in a filing it had extended its cloud services agreements with Amazon Web Services and Google through 2029, committing to spend $880 million and $580 million, respectively, over ⁠three years

• Pinterest’s third-quarter revenue of $1.17 billion missed analysts’ estimates of $1.21 billion, according to data compiled by LSEG

• Pinterest forecast fourth-quarter revenue ⁠of $1.425 billion to $1.475 billion, ‌below Wall Street estimates

• RBC analysts said ⁠changes to the EU’s de minimis exemption hit ​cross-border ‌sellers sooner and harder than expected, leaving ​Pinterest’s European ⁠revenue flat

• Reddit had fallen about 44% this year and Pinterest about 23% through Thursday’s close

• If current losses hold, Reddit is set to lose $5.7 billion in market value and Pinterest more than $800 million
