Polymarket Fees 2026: What Does It Actually Cost to Trade?

One of Polymarket's biggest draws is how cheap it is to trade. Here is exactly what you pay, and what you do not.

Trading fees

Polymarket has historically charged no fee to enter or exit a position, taking only a small cut on net winnings. That is dramatically cheaper than a sportsbook, where a typical -110 line bakes in roughly a 9% margin on every bet.

Because the price of a share is the implied probability, your cost is simply the price you pay. A share at 40c costs 40c and pays 1 USDC if it resolves yes.

Deposits, withdrawals and gas

Funding with USDC on Polygon costs only a few cents in network gas. Card funding may carry a processor fee. Withdrawals back to your own wallet are similarly low cost.
