Polymarket fee calculator

How it is calculated

Polymarket charges fees only to takers, the people who accept an order already in the book. The official formula is shares × rate × price × (1 − price). The rate depends on the category: 0.07 for crypto, 0.05 for sports, economics, culture, weather and combos, 0.04 for politics, finance, tech and mentions, and 0 for geopolitics. Because the formula multiplies price by (1 − price), the fee peaks when the contract is worth 0.50 and almost vanishes near 0 or 1. Full table and examples.

Three ways to pay less

• Place limit orders and wait for them to fill: as a maker the fee is zero.
• If you must take the book price, do it away from 0.50: at 0.90 you pay just over a third of what you pay at 0.50.
• Crypto has the highest rate of all; that is where the maker-taker gap is biggest.

Frequently asked questions

Is the fee deducted from winnings or paid separately?

It is charged when the order fills, in USDC, on top of the contract price. If you win, you receive 1 USDC per contract with no further deductions.

Do deposits or withdrawals have fees?

Polymarket charges nothing to deposit or withdraw. What you pay is the fee of the exchange where you buy USDC and, sometimes, the network.

Where do these rates come from?
