Fees
Trading fees on Polymarket.
Doji does not charge trading fees. Polymarket charges a taker fee on most markets when your order fills immediately.
Maker vs. Taker
- Takers pay a fee — your order fills immediately against existing orders.
- Makers pay nothing — your order rests on the book and is filled later.
A GTC limit order at a price that doesn't fill immediately makes you a maker. FAK or aggressive pricing makes you a taker.
Post-only orders guarantee you're always the maker — zero fees.
Fee Rates
Fees vary by market category. Geopolitical and world events markets are free.
| Category | Taker Fee Rate |
|---|---|
| Crypto | 0.072 |
| Sports | 0.03 |
| Finance / Politics / Tech | 0.04 |
| Economics / Culture / Weather / Other | 0.05 |
| Geopolitics | Free |
Fees are based on the number of shares, the price, and the fee rate. They're highest at 50% probability and decrease near the extremes ($0.01 or $0.99). Example: buying 100 shares of a sports market at $0.50 costs about $0.75 in fees.
Fee rates are set by Polymarket and may change. The order form always shows the current fee estimate before you confirm.
Deposits & Withdrawals
Polymarket doesn't charge deposit or withdrawal fees. The bridge provider may charge its own fees — the Doji bridge UI shows a breakdown before you confirm.
Maker Rebates
A portion of taker fees is paid out daily to market makers as USDC rebates.
