What Are Prediction Markets?

Prediction markets are platforms where participants buy and sell shares tied to the outcome of future events. The price of each share reflects the collective probability the market assigns to that outcome.

How Do Prediction Markets Work?

In a sports match, a market issues shares for each possible outcome (win/draw/loss). If you believe a team will win, you buy shares for that outcome. If it happens, each share pays 1 USDT; if not, the shares expire worthless.

Why Are Prediction Markets More Accurate Than Polls?

• Skin in the game: Participants wager real money, incentivizing careful research.
• Information aggregation: Prices aggregate dispersed knowledge from thousands of participants.
• Real-time updates: Prices shift instantly as new information emerges.
