Polymarket fees, explained with worked examples

How are Polymarket fees calculated?

Polymarket US's fee schedule, marked effective October 7, 2026, gives the trading fee in dollars as Θ × C × p × (1 − p). C is the number of contracts, p is the price in dollars from $0.01 to $0.99, and Θ is a coefficient. For a taker on a standard market, Θ is 0.0695. A taker is an order that fills right away against an order already on the book. The fee is largest near 50 cents and shrinks toward 1 cent and 99 cents. Sells use the same formula as buys.

Fees apply only when a trade executes. A taker fee comes out at trade time, and canceled, expired and rejected orders cost nothing. The coefficient has moved twice this year. A CFTC filing dated July 7, 2026 raised it from 0.05 to 0.06 from July 1, and a September 21 filing raised it from 0.06 to 0.0695 from September 17. The maker rebate stayed at 0.0125 both times. Rebates change next, at 1 PM ET on October 19, 2026, while the taker formula stays the same.

Polymarket US rounds with banker's rounding. A fee or rebate goes to the nearest cent, and an exact half goes to the even cent, so the fee page says $0.025 becomes $0.02 and $0.035 becomes $0.04. When one order fills against several resting orders, each fill's charge is adjusted so the total never exceeds the rounding of the exact combined fee.

• Price as a decimal: 50 cents is 0.50.
• Multiply the price by one minus the price: 0.50 × 0.50 = 0.25.
• Multiply by the number of contracts: 0.25 × 100 = 25.
• Multiply by the taker coefficient: 25 × 0.0695 = $1.7375.
• Round to the nearest cent, with exact halves going to the even cent. $1.7375 rounds to $1.74.

What do Polymarket US fees cost at 10, 30, 50, 70 and 90 cents?

Each row is 100 contracts bought at that price with an order that fills right away, so you pay the taker fee. The 10 and 50 cent rows match the 100-contract table on Polymarket US's fee page, and the 30, 70 and 90 cent rows come from the same formula. On 1,000 contracts the taker fee is $6.26 at 10 or 90 cents, $14.60 at 30 or 70 cents and $17.38 at 50 cents. As a share of what you pay, the fee is largest at low prices: 6.3% of cost at 10 cents against 0.7% at 90 cents.

Do these examples match Polymarket US's own fee page?

Yes, to the cent. Polymarket US prints worked examples on 1,000 contracts, and doddo's calculator reproduces each one with the formula above. Most of them land on an exact half before rounding. The taker fees of $6.255, $17.375 and $14.595 round up to the even cent, and the maker rebates of $1.125, $3.125 and $2.625 round down to $1.12, $3.12 and $2.62. A $1.125 rebate pays $1.12, not $1.13. The maker column uses the flat rebate that applies until 1 PM ET on October 19, 2026.

How do taker, maker and combo fees differ on Polymarket US?

Maker rebate: a maker order rests on the book until someone else fills it. Until 1 PM ET on October 19, 2026, Polymarket US credits it 0.0125 × contracts × price × (1 − price) at the fill, the same rate on every market, so $0.31 on 100 contracts at 50 cents. After that, only makers with $10 million or more of maker volume in the prior calendar month earn a rebate, at a lower rate set by tier. Combo fills carry no maker rebate.

Combos: a combo's taker fee is contracts × price × [0.0695 × (1 − price) + 0.06 × (1 − price)⁴]. It applies to the whole combo, not to each leg. Unlike the standard curve it is not symmetric. A 100-contract combo costs $1.92 at 50 cents and $1.02 at 10 cents, but only $0.63 at 90 cents.

Table Tennis: takers pay 0.10 in place of 0.0695, which is $25.00 on 1,000 contracts at 50 cents. Its maker rebate follows the same rules as every other market.

Volume rebates: high-volume takers get part of their taker fees back each week. The tiers change on October 19, 2026 and are set out below. The table below leaves these rebates out.

What changes to Polymarket US rebates on October 19, 2026?

Polymarket US's fee schedule moves both rebates to volume tiers at 1:00 PM ET on Monday, October 19, 2026. The taker fee formula and its coefficients, 0.0695, Table Tennis 0.10 and the combo curve, do not change. What changes is who gets money back.

From that time, the maker rebate depends on your maker volume in the prior calendar month. Below $10 million there is no rebate, so most people placing resting orders will get nothing. Table Tennis uses the same maker tiers, and combo fills still earn no maker rebate. A separate extra weekly maker rebate on crypto markets ends earlier, at 8:00 AM ET on October 15, 2026.

Volume is the dollar amount you paid for the positions you received, not the contracts' face value, counted by calendar month in Eastern Time. For the October 19 launch only, Polymarket US uses the higher of your September 2026 volume or four times your volume from October 12 to 18. From November 1, tiers reset on the first of each month.

Do high-volume Polymarket US takers get fees back?

Takers pay the fee in full at trade time. If your taker volume in the prior calendar month was high enough, Polymarket US pays back a share of the taker fees you paid, combo taker fees included, each week. The October 19 change lowers the shares and adds tiers. Most people trade far below $250,000 a month and get no taker rebate before or after.

How do you deposit on Polymarket US, and what does it cost?

Polymarket US lists seven ways to fund an account: debit card, bank transfer (ACH), Apple Pay on iPhone, PayPal, Venmo, USDC on iPhone where available, and wire transfer. Its deposit pages mention no deposit fee. "Not published" in the table means the page does not say.

Deposits other than wires can give you instant buying power while they process, up to a cap, so part of a larger deposit may open up only once it clears. Money that has not cleared can be traded but not withdrawn. Every deposit must come from an account in your own name, and identity (KYC) and anti-money-laundering (AML) checks can hold funds until they finish.

Is there a Polymarket withdrawal fee, and how long does a withdrawal take?

Polymarket US describes withdrawals as free, and none of its withdrawal pages list a fee. They do not publish a minimum or a maximum either. In the app you can withdraw to a debit card, a bank account (ACH), Apple Pay (iPhone only, and only if you deposited with Apple Pay), PayPal or Venmo (only to an account you deposited with), or USDC to a crypto wallet (iPhone, where available). Wire withdrawals are not in the app, so you contact support for one.

Two rules set the timing. First, a withdrawal is available only for deposits that have fully cleared, which typically takes 3 to 4 business days. Weekends and holidays do not count. Second, the money must return to the funding source you deposited with, in the order the deposits were made. If you deposit $100 by debit card and later $200 by ACH, the first $100 you withdraw goes back to the card. Polymarket US says this keeps it in line with anti-money-laundering rules.

If a deposit is still pending after 5 business days, Polymarket US says to contact support. Promotional credit is a trading credit, not cash, and it cannot be withdrawn. The Kalshi vs Polymarket US guide covers the credit rules.

Why can't you withdraw from Polymarket US?

Polymarket US's help pages give these reasons a withdrawal is unavailable or delayed. Most often it is the first one.

• The deposit has not fully cleared. That usually takes 3 to 4 business days, and the same wait applies to proceeds from trading with instant buying power.
• The method does not match. A withdrawal must go back to the original funding source, never to a new or third-party account. If that method is no longer active, contact support.
• The bank details are wrong or out of date. ACH withdrawals are rejected in that case, so relink the correct account.
• An anti-money-laundering review is open. Polymarket US reviews every withdrawal, and the check can delay processing until verification finishes.
• The balance is promotional credit. The credit itself is never withdrawable, even after you use it, but cash above it is, and so are eligible trading proceeds.

What does polymarket.com charge, and can US users use it?

polymarket.com, the international site, is a separate product with its own fee page. Polymarket's docs call it the international, crypto-based product and describe Polymarket US as the fiat-based, US-regulated platform. The geoblock page lists the United States as close-only on polymarket.com, which means people in the US can close existing positions but cannot open new ones. US users should use Polymarket US and the rates above.

For comparison, the international fee page charges takers C × rate × p × (1 − p), with a rate set by category, and says makers are never charged fees. It shows no effective date, so check it before you rely on it. The same docs say Polymarket charges no fee to deposit or withdraw USDC, while intermediaries such as Coinbase or MoonPay may charge their own.

How do Polymarket fees compare with Kalshi fees?

Polymarket US and Kalshi are close on a single taker trade. The differences come from resting orders and funding. The full Kalshi formula, series multipliers and deposit costs are in the Kalshi fees guide, and the Kalshi vs Polymarket US guide compares regulation, state limits and signup credits.

Is there a Polymarket fee calculator?

doddo's Polymarket calculator applies this schedule to any price and number of contracts, as a taker, maker, combo or Table Tennis order, and shows the fee, total cost, payout and break-even probability. The Kalshi fee calculator runs the same math for Kalshi and Robinhood. The fee shown in the app is the one that counts.
