Question 5

What are prediction markets?

Accepted Answer

Prediction markets are exchange-traded markets where participants buy and sell contracts based on the outcome of future events. Prices reflect the crowd's collective probability estimate — for example, a contract trading at $0.70 implies a 70% chance of that event occurring. They are often more accurate than polls or expert forecasts because participants have real money at stake.
