Reddit shares tumble about 30% after Q3 earnings warn of Google AI search traffic loss

Reddit reported third‑quarter 2026 revenue of $895 million, up 53% year over year, but said traffic from Google search had fallen sharply after Google introduced AI Mode. CEO Steve Huffman attributed a loss of more than one million weekly visits to the new AI feature and warned that daily active uniques could decline double‑digit percentages in the fourth quarter. The company also lowered its Q4 revenue guidance to $1.00‑$1.03 billion, below the $1.05 billion consensus. The market reacted with the stock falling roughly 29‑30% on the day after the release.

Investors saw the stock drop about 29% as the market priced in the risk of a shrinking audience despite strong revenue growth. The below‑consensus Q4 guidance adds further downside pressure on the share price.
