Polymarket US Fees, Explained With Examples
Polymarket US's fee schedule charges a taker fee when your order executes against a resting order. The fee is 0.0695 times the number of contracts times the price times one minus the price, so it peaks at 50 cents and shrinks near 0 or $1. A 100-contract trade at 50 cents costs at most $1.74 in fees.

The formula
Polymarket US's fee schedule uses one symmetric formula for standard taker fees and maker rebates: Fee = ฮ ร C ร p ร (1 โ p). C is the number of contracts, p is the trade price between $0.01 and $0.99, and ฮ (theta) is the fee coefficient.
Standard coefficients from Polymarket US's fee schedule
| Theta | Maximum, 100 contracts at $0.50 | |
|---|---|---|
| Taker fee | 0.0695 | $1.74 |
| Taker fee, table tennis markets | 0.10 | $2.50 |
| Maker rebate | โ0.0035 to โ0.0104 by tier | โ$0.09 to โ$0.26 |
The p ร (1 โ p) term is why the fee follows price uncertainty. At 50 cents it equals 0.25, its largest value. At 10 cents it is 0.09, and at 99 cents it is under 0.01.
Polymarket US's own worked examples
The fee schedule works through several trades of 1,000 contracts each. Three of them:
- Buying 1,000 contracts at $0.10: the buyer, as taker, pays 0.0695 ร 1,000 ร 0.10 ร 0.90, which is $6.26.
- Buying 1,000 contracts at $0.65: the taker pays 0.0695 ร 1,000 ร 0.65 ร 0.35, which is $15.81.
- Selling 1,000 contracts at $0.30 as the aggressor: the seller is the taker and pays 0.0695 ร 1,000 ร 0.30 ร 0.70, which is $14.60.
In each example the resting side, the maker, earns a rebate instead if it is in a rebate tier.
Who pays: takers and makers
Polymarket US's market-data page says a market order makes you a taker, "taking liquidity," and a limit order that rests on the book makes you a maker, "providing liquidity for others to trade against." Our page on how Polymarket US prices work explains the order book in more detail.
Makers below $10,000,000 of monthly maker volume, Tier 1, get no rebate. Rebates start at Tier 2 with a coefficient of โ0.0035, about 5 percent of the standard taker fee, and reach โ0.0104, about 15 percent, at Tier 4, which starts at $200,000,000 of prior-month maker volume. Tiers are set by the prior calendar month. A separate taker rebate returns a share of taker fees paid, set by taker volume, and is paid weekly.
A smaller example, worked the same way
The fee schedule's examples use 1,000 contracts, but the formula scales down the same way. For 10 contracts bought at $0.40 as a taker, the arithmetic is 0.0695 ร 10 ร 0.40 ร 0.60, which comes to $0.1668. Rounded to the cent, the fee is $0.17.
At the edges of the price range the fee shrinks fast. For the same 10 contracts at $0.95, the formula gives 0.0695 ร 10 ร 0.95 ร 0.05, or about $0.033, which rounds to $0.03. This is the effect Polymarket US describes when it says fees on small trades or prices near $0.00 or $1.00 can round down.
These figures only illustrate the formula. They aren't a view on any market or a suggestion of what to trade.
Fees are separate from the spread
Polymarket US's spread guide says market orders "buy at the ask and sell at the bid," and that "wider spreads increase your trading cost." The fee schedule's formula is a separate charge, calculated from the trade price. Our guide to how Polymarket US prices work explains bids, asks and spreads.
Rounding and small trades
All fees and rebates are rounded to the nearest cent using banker's rounding, which rounds a half cent to the nearest even cent: $0.025 becomes $0.02 and $0.035 becomes $0.04. On small trades, or at prices near $0.00 or $1.00, Polymarket US says the fee can round down to nothing.
When one order fills against several resting orders, each fill is rounded on its own, with an adjustment so the total never exceeds the rounded fee on the whole order. Polymarket US says that adjustment can only lower a fill's charge, never raise it.
When no fee is charged
Fees apply only when a trade executes. Polymarket US says canceled, expired and rejected orders carry no fee. Its help center describes withdrawing your cash as free. Combo trades have their own taker fee schedule and no maker rebate.
Promotional trading credits can be used to pay applicable fees, under Polymarket US's incentive program terms. If you're opening a new account, the Polymarket promo code SPLASH page explains that credit.
