Polymarket fees, plain
How the taker fee works
Polymarket charges takers rate × shares × p × (1 − p), where p is the share price in dollars. The p × (1 − p) part peaks at 50¢, so fees are largest on coin-flip markets and shrink toward 1¢ and 99¢.
The fee is charged when the trade fills, on top of what you pay for the shares.
Polymarket US vs. the international exchange
Polymarket US is the version available to US traders. Its published schedule uses one rate for most markets, with separate rates for some products such as combos. The international exchange sets a rate per market category, and geopolitics markets are fee-free.
Both schedules changed in 2026, which is why the rate here is editable. If Polymarket updates it, type in the new number.
Makers, takers, and rebates
A taker order fills immediately against an order already on the book. A maker order is a limit order that rests on the book until someone else fills it. Makers pay no fee: on Polymarket US they receive a rebate when the order fills, and on the international exchange they share a daily rebate pool funded by taker fees.
Why fees change your break-even
A share at 40¢ implies a 40% chance. Add a taker fee and your cost per share rises, so the outcome has to happen a bit more often than 40% of the time for the trade to break even. The calculator shows that number next to the price.
