Polymarket does not charge fees on most markets. However, 15-minute crypto 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
15-minute crypto markets 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.
