When a market closes, PredictIt redeems all of the existing shares in that market. If your prediction comes true, you functionally sell your shares back to us for $1. Otherwise, their value is zero. The closing price and the calculation of your profit and our fee appear in History.
Contracts in multiple-option markets are closed sequentially, with the contract that resolved to “Yes” always closed last (at the top of the list for that market in History). As we close each contract, we recalculate your market risk based on your holdings in contracts that remain to be closed. Your overall credit in the market will be the sum of your credit in each individual contract.
