The simExchange is a web-based prediction market in which players use virtual money to buy and sell stocks and futures contracts in upcoming video game properties.

The main purpose of the web site is to predict trends in the video game industry, particularly how upcoming products will sell and how they will be received by the critics.

The web site also features a number of "Wisdom of the crowd"-type content collaboration and aggregation tools, including means for sharing information, articles, images, and videos about the games.

The website also features a number of user tools to aggregate and display information about video games and publishers.

In March 2010, a number of these content submission tools, such as the ability to submit images and video, were removed due to lack of use, although the features remain advertised in the site's tutorials.

It originally launched with only stocks that forecast the global lifetime sales of gaming products.

[12] The discontinuation of this service corresponded with the NPD Group's decision to cease publicly releasing hardware and software unit sales numbers.

[17] The simExchange's prediction market data has been used by Wall Street analysts, such as Michael Pachter,[citation needed] in their published notes and financial news outlets, such as Reuters, MarketWatch, and TheStreet.com.
