Polymarket fees
Only the taker side of a trade pays a fee, and only on some markets: geopolitics and world-events markets are fee-free. Rates are set per category, from 0 (geopolitics) to 0.07 (crypto). The fee is applied as shares × rate × price × (1 − price), so the fee is largest at 50¢ and falls towards either end. Makers are never charged and receive a rebate. There is no Polymarket fee to deposit or withdraw USDC, though on-ramps such as Coinbase or MoonPay may charge their own.

A worked $100 position
The fee is shares × rate × p × (1 − p). $100 at 50¢ in a politics market buys 200 shares: 200 × 0.04 × 0.5 × 0.5 = $2.00. The same $100 at 80¢ costs $0.80, and at 95¢ $0.20. Makers pay nothing.

Where it costs most
A quadratic fee scales with price × (1 − price): it peaks at 50¢ and falls towards 0¢ and 99¢. Trading a genuine toss-up costs the most per contract, and buying something the market already considers near-certain costs the least, the opposite of how a flat commission behaves. On Polymarket, geopolitics markets carry no fee at all.

Common questions
Does Polymarket charge a flat fee per trade?
No. The fee is quadratic in the contract price, so the cost depends on the price you trade at and, on some venues, the market.
Do makers pay fees on Polymarket?
No. Only the taker side of a trade pays; makers are never charged and receive a rebate.
