# Understanding Prices

*Prices (odds) represent the current probability of an event occurring.* For example, in a market predicting whether the Miami Heat will win the 2025 NBA Finals, if YES shares are trading at 18 cents, it indicates a 18% chance of Miami winning.

These odds are determined by what price other Polymarket users are currently willing to buy & sell those shares at. Just how stock exchanges don’t “set” the prices of stocks, Predicton does not set prices / odds - they’re a function of supply & demand.

When a market is resolved, holders of winning shares receive $1 per share, losing shares become worthless, and trading of shares is no longer possible.
