Polymarket’s fee structure looks simple on the surface — “no deposit fees, no withdrawal fees” — but the actual cost of a trade depends on several factors most users don’t realize. After the March 2026 fee rollout and the April 2026 exchange upgrade, the math changed enough that even regular users are still recalibrating. Here’s the full breakdown.
The short version
For a typical user placing a few trades a month, the fees you’ll actually encounter are:
- Trade fees: Variable, depending on whether you’re a maker or taker, and which category you’re trading
- Deposit and withdrawal fees: Zero on the platform side, but third-party costs may apply
- Network gas fees: Tiny on Polygon, but not zero
- Conversion costs: If you deposit crypto other than USDC, you’ll pay DEX spread on auto-conversion
Polymarket itself charges nothing on deposits or withdrawals. The platform takes nothing on transfers.
Trade fees: maker vs. taker
This is where the real money is. Polymarket runs an order-book exchange (similar to a stock market), and every trade has two sides:
- Makers post limit orders that sit on the book waiting to be filled. They add liquidity to the market.
- Takers place orders that fill immediately against existing limit orders. They remove liquidity.
Makers pay zero fees on Polymarket. Better than that — makers can earn rebates from a program that pays them in pUSD daily, with the rebate amount depending on the category. The percentage of taker fees that go back to makers as rebates has historically been around 20-25% for crypto, sports, and politics, with rebates calculated per market rather than across the platform.
Takers pay a variable fee based on category and the price of the contract. As of the March 2026 fee structure rollout, the peak fees per 100 shares are:
| Category | Peak taker fee per 100 shares |
|---|---|
| Sports | $0.75 |
| Politics, finance, tech | $1.00 |
| Economics, culture, weather | $1.25 |
| Crypto | $1.80 |
| Geopolitics | $0.00 (currently fee-free) |
A few things to understand about these numbers:
The fee scales with implied probability. The peak fee is at the 50/50 price point, where uncertainty is highest. Trades near the extremes ($0.01 or $0.99) incur much smaller absolute fees. This is intentional — the platform doesn’t want to discourage users from trading “near-certainty” markets.
Sell orders are not subject to taker fees. This is a quiet but important detail. If you bought shares earlier and want to exit your position by selling, that sell order doesn’t pay the taker fee even if it fills against the book.
Fees are now charged in pUSD, not in shares. Before the April 2026 upgrade, fees were deducted from your share count, which made them confusing. After the upgrade, fees are charged in pUSD instead of in shares, which makes them readable on your trade history rather than baked into share counts.
Deposit costs
Depositing to Polymarket itself is free. But depending on how you fund your account, you may still pay something:
Direct USDC transfer (Polygon): The cheapest option. Polymarket charges nothing, and Polygon network gas is typically under a cent. If you already have USDC on Polygon, this is essentially free.
Direct crypto transfer (other chains): Polymarket auto-converts deposits in ETH, BTC, SOL, and other major tokens to USDC. The conversion uses market rates with standard DEX spreads. Realistically, expect to lose 0.1% to 0.5% on the conversion depending on the token and amount.
Debit card via Coinbase or MoonPay: Convenient but expensive. These on-ramps can charge 2-4% on top of the conversion costs.
Bank transfer (US version only): US users funding through approved futures commission merchants typically face standard ACH or wire fees from the FCM, not Polymarket itself.
The cheapest path for most users is to buy USDC on a major exchange and withdraw it directly to Polygon, then deposit on Polymarket.
Withdrawal costs
Withdrawals from Polymarket are free on the platform side. You’ll pay only network gas fees, which on Polygon are negligible. If you want to move funds from Polygon back to Ethereum mainnet, you’ll pay a Polygon-to-Ethereum bridge fee, which can be a few dollars depending on Ethereum gas conditions.
How to minimize what you pay
A handful of habits dramatically reduce fees:
Use limit orders whenever possible. Maker orders pay zero fees and are eligible for rebates. The trade-off is that limit orders may not fill — if the price moves away from your limit, you miss the trade. For most non-urgent positions, limit orders save real money.
Trade fee-free categories. Geopolitics markets currently incur no taker fees. If you have edge in that category, the fee structure is essentially zero.
Avoid market-order taker fills in crypto. Crypto markets have the highest taker fee rate. If you must trade crypto markets, use limit orders.
Trade near the extremes when possible. Buying shares priced near $0.01 or $0.99 incurs minimal fees because the fee curve peaks at 50/50 uncertainty.
Fund directly, not through card on-ramps. A direct USDC transfer from a wallet sidesteps the 2-4% in fees that Coinbase and MoonPay add when you fund with a debit card.
How Polymarket fees compare to alternatives
Versus traditional sportsbooks: not even close. Sportsbooks bake in a “vig” of 5-10% by setting odds against you. Polymarket’s max taker fee of 1.8% in crypto markets — and zero in geopolitics — is a fraction of that.
Versus Kalshi (the main US-regulated competitor): Kalshi charges roughly comparable per-trade fees, with similar maker/taker dynamics. Kalshi’s structure has historically been a bit more straightforward but slightly less generous on rebates.
Versus traditional brokerages: prediction markets aren’t directly comparable to stock trading on fees. The closer comparison is options trading, where commission-free brokerages still charge regulatory fees of cents per contract.
Common fee questions
Are there any hidden fees on Polymarket?
The platform doesn’t add hidden fees beyond what’s documented. The “hidden” costs people complain about are usually third-party costs (debit card on-ramps, gas during network congestion, DEX spread on non-USDC deposits) rather than Polymarket fees themselves.
Why did my $100 deposit show up as less than $100?
Most likely either a debit card on-ramp fee, a token conversion (if you didn’t deposit USDC directly), or rare cases of high gas during network congestion. Direct USDC-on-Polygon transfers should arrive at roughly 1:1.
Do I pay fees when I withdraw winnings?
Not on Polymarket’s side. You’ll pay gas to move funds back to your wallet, and exchange fees if you later swap pUSD/USDC for fiat or another token.
How does the maker rebate program work?
Limit orders that sit on the order book and get filled by other users qualify as maker orders. A portion of the taker fees collected from the other side is paid back to makers as rebates. Payouts happen daily in pUSD. You compete only with other makers in that specific market for the rebate pool.
Are fees the same on the US platform?
The US platform’s fee structure is similar in concept but has slightly different specific rates due to the regulatory wrapper. Since the US platform is still rolling out as of mid-2026, fee specifics may continue to adjust.
The bottom line
For occasional users placing modest trades, Polymarket fees will rarely exceed a few percent of your activity, and often less. For active users willing to use limit orders and concentrate on lower-fee categories, fees can be near zero or even net-positive after rebates.
The biggest fee mistakes new users make are using debit cards to fund (paying 2-4% to on-ramps) and exclusively using market orders (paying full taker fees on every trade). Both are easy to avoid once you know they exist.
