Fees
Understanding trading fees on Polymarket
Polymarket does not charge fees on most markets. However, certain markets have taker fees enabled to fund the Maker Rebates Program.
Fee-Free Markets
The vast majority of Polymarket markets have no trading fees:
- No fees to deposit or withdraw USDC (though intermediaries like Coinbase or MoonPay may charge their own fees)
- No fees to trade shares
Markets With Fees
The following market types charge a small taker fee on each trade. These fees are collected and redistributed daily to market makers as rebates, incentivizing deeper liquidity and tighter spreads.
- 15-minute crypto markets
- 5-minute crypto markets
- NCAAB (college basketball) markets (starting February 18, 2026 for new markets)
- Serie A markets (starting February 18, 2026 for new markets)
Fee Structure
Fees are calculated using the following formula:
fee = C × p × feeRate × (p × (1 - p))^exponent
Where C = number of shares traded and p = price of the shares. The fee parameters differ by market type:
| Parameter | Sports (NCAAB, Serie A) | 5-Min & 15-Min Crypto |
|---|---|---|
| Fee Rate | 0.0175 | 0.25 |
| Exponent | 1 | 2 |
| Maker Rebate % | 25% | 20% |
Taker fees are calculated in USDC and vary based on the share price. However, fees are collected in shares on buy orders and USDC on sell orders. The effective rate peaks at 50% probability and decreases symmetrically toward the extremes.
