What is Car Stock Exchange?
Car Stock Exchange (CSX) is an online game that allows players to buy and sell fictitious stock in upcoming new automobiles. CSX is a “prediction market” game that allows players to trade stock based on their predictions of the domestic unit sales of various vehicles. The game is free to play and does not involve real money or stock.
If you are already a member of the Edmunds Automotive Network, you have received CSX$1,000,000 in your account; if you are not already a member, CSX$1,000,000 will be deposited in your account when you sign up. When you play CSX, you use these CSX$ to trade stocks, build your Portfolio and attempt to increase your Net Worth.
