Reddit's third-quarter revenue and earnings exceeded expectations, but its fourth-quarter sales guidance was weak, causing its stock price to plummet over 11% in after-hours trading. The company also plans to require all users to create official accounts, stating that this move aims to counter the impact of reduced Google search traffic. Reddit's third-quarter daily active unique users (DAUq) increased by 12% year-over-year to 130.3 million, but fell short of Wall Street expectations, with U.S. DAUq declining by 2% year-over-year. CEO Huffman stated that the continuous advancement of Google AI has led to a fundamental shift in search referral traffic, and the company will focus more on logged-in users. Reddit plans to begin testing new registration requirements outside the U.S. in the fourth quarter.
