Gas fee
Gas is how blockchain validators are paid. Polymarket pays it in MATIC (Polygon's native token).

Definition
A gas fee is the cost of executing a transaction on a blockchain. On Polygon (where Polymarket runs), gas is ~$0.01 per trade.
Plain-English explanation
Every blockchain transaction consumes computational resources and costs gas. Polygon's gas is denominated in MATIC. For normal Polymarket trading, gas is negligible — a penny per trade. Keep a small MATIC balance in your wallet if you self-custody.
Example
A Polymarket trade costs 0.03 MATIC ($0.01 at current MATIC price).
