The Wall Street Journal today covers a new sports market called OneSeason. OneSeason is a stock market game based on buying and selling shares of professional sports stars. It’s not the first of it’s type, of course. ProTrade has a similar market, but this game trades on valuations and real money trades hands depending on whether you trade. Your gains and losses are real.

You have a “sportfolio” and buy, sell, and trade players in the sports of football, baseball, and basketball. If other traders begin buying up Manny Ramirez, the value goes up. If there’s a sell off on Alex Rodriguez, his value goes down.

It makes a lot of sense and it appears that the CEO of the company, Michael Sroka, has thought this out and that it is legal and does not violate anti-gambling laws. In a time of market losses on Wall Street, maybe sports fans have an investment edge with OneSeason.
