The short answer first: getting money in and out of Polymarket is free on the platform’s side, and trading costs are small - but not zero, and not evenly distributed. As of mid-2026 the fee model rewards patient orders and punishes impatient ones, which means the difference between a profitable and a losing month can literally be your order type. Here is the complete cost map.
Trading fees: takers pay, makers earn
Most markets carry a taker fee - charged when your order executes against existing liquidity. Rates vary by category, with maximums roughly between $0.75 and $1.80 per 100 shares; geopolitical markets trade fee-free. Maker orders - limit orders that rest in the book - pay nothing and currently earn rebates of about 20-25% of the taker fees they match. The practical rule writes itself: anything beyond a small casual trade should go in as a limit order. You get a better price and the fee sign flips from minus to plus.
What fees do to your breakeven
Fees quietly move the threshold we derived in how to read Polymarket odds. Buy at 60¢ with zero fees and you need a 60% winrate; add a taker fee of about a cent per share and your real breakeven creeps toward 61%. One point sounds like nothing - until you remember that most edges on liquid markets are only a few points wide. Serious traders compute breakeven on the all-in price: share price plus fee plus expected slippage.
Deposits: PUSD, USDC and the network trap
Polymarket balances are held in PUSD, the platform’s dollar-pegged stablecoin. You do not need to buy it anywhere: deposit USDC - or any of the twenty-plus supported tokens - and it converts automatically on arrival. Card and bank options exist in some regions through third-party providers, whose fees are theirs, not Polymarket’s. The one mistake that actually costs people money is the network: USDC must travel over Polygon. Pick the wrong chain in your exchange’s withdrawal form and the deposit can be gone for good. First time? Send $10, confirm it lands, then send the rest. Minimums are friendly: $1 for market orders, 5 shares for limit orders.

Withdrawing is the mirror image: free on Polymarket’s side, paid out as USDC over Polygon, arriving in minutes with gas costs measured in fractions of a cent. Send to your own Polygon wallet or straight to an exchange that supports USDC on Polygon - verify that support before pasting the address, because the network trap works in both directions.
The costs nobody itemizes
Three lines missing from every fee schedule. Spread - on thin markets the gap between bid and ask is a real cost you pay on entry and again on exit; it routinely dwarfs the official fee. Slippage - market orders in shallow books fill worse than the displayed price. Fiat conversion - the exchange where you turn euros or dollars into USDC takes its own cut, often the largest single cost of the whole pipeline. If you track one number, track your all-in cost per trade, not the platform fee.
Pre-deposit checklist
- USDC on hand at an exchange that supports Polygon withdrawals.
- Test transfer of ~$10 first; full amount after it arrives.
- Limit orders as your default; market orders only on liquid books.
- Breakeven computed on all-in price - share plus fee plus slippage.
- Ten minutes on the live windows before the first real order - see what you are pricing before you pay to price it.
