Reddit

Reddit ( RED-it, formerly stylized reddit) is an American proprietary social news aggregation and forum social media platform. Registered users (commonly referred to as "redditors") submit content to the site such as links, text posts, images, and videos, which are then voted up or down ("upvoted" or "downvoted") 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 moderate the communities. Moderation is also conducted by subreddit-specific moderators, who are unpaid volunteers. It is operated by Reddit, Inc., based in San Francisco.

As of December 2025, Reddit is one of the most-visited websites in the world. According to data provided by Similarweb, 51.75% of the website traffic comes from the United States, followed by Canada at 7.01%, the United Kingdom at 6.97%, Australia at 3.97%, Germany at 3%, and the remaining 28.37% split among other countries.

Reddit was founded by University of Virginia roommates Steve Huffman and Alexis Ohanian in June 2005, who were joined by Aaron Swartz that November. Condé Nast Publications acquired the site in October 2006. In 2011, Reddit became an independent subsidiary of Condé Nast's parent company, Advance Publications. Reddit debuted on the stock market on the morning of March 21, 2024, with the ticker symbol RDDT. The current market cap as of July 2024 is US$10 billion.
