Market mechanics

Prediction market mechanics determine what is being priced and how a contract reaches an outcome. These guides explain questions, contracts, deadlines, orders, and resolution with attention to the details that readers can miss when following a fast-moving headline.

Start with the fundamentals, then compare the Polymarket and Kalshi reading guides. A useful habit is to write the event definition in your own words before checking the quote. If you cannot explain what would settle the contract, the percentage alone is not enough context. Each platform guide points to one official source for checking the current product rules.
