Reddit is an American social news aggregation and forum platform where registered users can submit content such as links, text posts, images, and videos, which are then voted up or down by other members. Posts are organized by subject into user-created boards called "subreddits". Submissions with more upvotes appear towards the top of their subreddit and, if they receive enough upvotes, ultimately on the site's front page. Reddit administrators and subreddit-specific moderators, who are unpaid volunteers, moderate the communities. Registering for an account is free and requires an email address. In Reddit style, usernames begin with "u/".
Founded in June 2005 by Steve Huffman and Alexis Ohanian, Reddit has become a major force in online culture and political activism. The platform debuted on the stock market on March 21, 2024, with the ticker symbol RDDT. As of July 2024, Reddit's market cap is US$10 billion. In 2019, Reddit reported approximately 430 million monthly users. Recent data indicates that weekly active users of Reddit's search tools grew 30% year-over-year, highlighting increasing engagement with the platform's search functionalities. Reddit is also working on incorporating AI into its search functions, using Google's Gemini model to power parts of its AI-enhanced search features.
