Trade Prediction Markets

A prediction market is a platform where you trade on the outcomes of future events, such as politics, sports, crypto or culture. Most markets offer a yes-or-no choice. If the event goes your way, your contract pays out a fixed amount; if not, you lose what you put in. The price of a contract reflects how likely the market thinks the event is.
