Election stock market is a way of predicting what will happen in an election. People buy and sell stocks (like buying and selling shares on the stock market) that represent different outcomes in an election, such as the winner of the election or how many votes a certain party will get. When the election is over, the person who bought the stocks that correctly represented the election results will make a profit (money). It's like a guessing game to see who can guess the right result of the election.
