And it's probably something you never anticipated-namely, the turning of possible outcomes into tradable futures contracts, which are sold on prediction markets open to the public. When participants are convinced of an outcome, they will buy its contract even at a high price; and, conversely, if they're sure it won't happen they'll sell even at a low price.
當然有，而且是讓你絕對料想不到的方式，那就是把這些未來事件當成「期貨交易」般，讓眾人下單買賣；意即──當參與者若對該事件的發生機率有絕對把握，可用高價買進；反之則低檔殺出。
