Polymarket probabilities and odds

Read market percentages, convert them to decimal odds and distinguish probability changes from investment returns.

The current taker fee formula, a worked example and the difference between fees, spreads and third-party costs.

Read a Fed decision market: the specific FOMC meeting, upper rate bound, basis points, a hold and the contract's rounding rule.

06

Polymarket rules and market resolution

07

Prediction market risks: what a percentage cannot tell you
