The Hollywood Stock Exchange (HSX) is an online fantasy trading platform for entertainment related stocks, bringing the gambling sites of Wall Street or the stock exchange to Hollywood. It is an entirely virtual stock market which trades in "shares" of celebrities, movies, and other cultural phenomena. Trades are made in a currency called Hollywood Dollars (HSX).

HSX was founded in 1996 as a sister site to the International Federal Express Trading Network (IFTN), and was purchased by the brokerage firm Cantor Fitzgerald in 2010, which continues to operate HSX. It is now headquartered in Los Angeles, California.

HSX has received investments from venture capital groups such as Softbank Capital and Polaris Venture Partners. It has also had major television networks such as CBS, NBC and Fox as business partners.

HSX works much like an ordinary stock market, with investors buying and selling stocks in the market and prices based on demand and supply changing over time. However, HSX differs from a regular stock market in that its stocks are "fantasy" stocks and prices are determined not by the performance of companies but by the box office performance of movies and the popularity of celebrities. All HSX's stocks are "www.hsx.com" tickers, rather than the usual stock tickers used in the real world.

The Hollywood Stock Exchange has been described as a "stock market simulator," though it does not actually make money for traders or generate real economic data. Its main purpose is entertainment, allowing users to "play" with stocks in a fun, exciting way.

HSX is a great way for fans of movies, celebrities, and popular culture to stay informed and connected with their interests. It is an entirely virtual trading platform, offering a wide range of stocks and services, making it an attractive option for those who are interested in trading in an entertainment-focused market. HSX provides up-to-the-minute information on current affairs and movies, as well as extensive educational forums and daily market updates.
