Understanding Polymarket fees matters before you place any trade, since costs directly affect your net results over time. This guide covers fee categories, the maker rebate, and a fully hypothetical worked example.
Polymarket Fees By Market Category
Polymarket has historically applied different fee structures depending on the type of market and the type of order placed. Rates can change over time and can vary by category, so nothing here should be treated as current pricing.
- Standard markets: [verify before publishing: current taker fee for standard/political markets].
- Sports markets: [verify before publishing: current taker fee for sports markets].
- Other specialized categories: [verify before publishing: any category-specific fee schedule that may apply].
Always check Polymarket's current fee schedule directly before trading, since these figures change over time and by category. Our fee calculator can help you estimate costs once you've confirmed current rates yourself.
Taker Vs. Maker Orders
Fees often depend on whether your order takes liquidity (matches an existing order immediately) or makes liquidity (sits on the order book waiting for a match).
- A taker order usually pays a fee, at a rate that is [verify before publishing: current taker fee rate].
- A maker order may qualify for a rebate instead of a fee, at a rate that is [verify before publishing: current maker rebate rate].
Which category your order falls into can depend on exact timing and order type, so it's worth understanding the mechanics before assuming which side you'll land on.
The Maker Rebate Explained
A maker rebate is a small payment back to traders who add liquidity to the order book, rather than instantly matching an existing order already sitting there. Platforms use rebates to encourage more resting orders, which can improve pricing for everyone trading that market.
The exact maker rebate rate on Polymarket is [verify before publishing: current maker rebate rate and eligibility conditions]. Eligibility can depend on market category, order size, or account status, so confirm details directly with Polymarket before relying on this benefit in your planning.
Why Rebates Matter For Frequent Traders
For someone who trades often across many markets, a maker rebate can offset some trading costs over time, improving overall efficiency. But rebates are not a source of guaranteed income, and the eligibility rules behind them can change without much notice.
It's also worth noting that placing maker orders means waiting for a match, which introduces its own risk: the market can move before your order fills, or it may not fill at all.
A Worked Example (Hypothetical Rates)
The numbers below are clearly hypothetical, used only to illustrate how the math works. They are not Polymarket's actual current rates, and should not be used to plan real trades.
Assume, hypothetically, a taker fee of 2% and a maker rebate of 0.5%, both applied to total trade value, purely for illustration purposes.
| Role | Trade Value | Hypothetical Fee/Rebate | Net Effect |
|---|---|---|---|
| Taker | $100 | 2% fee = $2.00 | Pays $2.00 total |
| Maker | $100 | 0.5% rebate = $0.50 | Receives $0.50 total |
If you buy a YES share at 62 cents as a taker under this hypothetical 2% fee, your all-in cost per $100 traded becomes $102.00 instead of $100.00. That shifts your effective break-even point higher than the quoted 62-cent price. Real fees may differ substantially; always use current confirmed rates, never these hypothetical numbers, when planning an actual trade.
Fees And Your Strategy
Fees affect your expected value on every single trade, even small ones, because they're a guaranteed cost regardless of outcome. Before estimating potential outcomes for a trade, read expected value to understand how costs factor into these calculations properly.
Position sizing also interacts with trading costs over a series of trades. See Kelly position sizing for a structured way to think about how much to risk per position, accounting for costs.
Confirming Current Fees
Because fee schedules change over time, never rely on older articles, forum posts, or hearsay for exact numbers. Cross-check everything with Polymarket's own current documentation directly.
Once you've confirmed real numbers from an official source, use our fee calculator to model how those costs affect a specific trade you're considering.
Risk And Availability Reminder
Fees are only one part of the overall picture when trading. Trading still carries the risk of losing your full stake on any position, regardless of the fee structure involved.
Access also depends on your country, so check the countries page and review responsible trading before trading with any real funds.
