The animated map below depicts the changes over time in the state-by-state Intrade contract prices for the 2008 presidential election. There is a brief pause before the animation starts again. 

Animated 2008 Electoral Map


Traders at the Intrade prediction market wager real money on contracts for each state, based on how they think the state will award its electoral votes in the 2008 presidential election.  Those who guess  correctly are rewarded with the money of those who guess incorrectly.

If the contract is trading at "50," it is an even money wager.  Potential gains for buyers and sellers change accordingly with higher or lower contract prices.  For more information on how the market works visit
