What does Polymarket charge? Less than most people expect, but no longer nothing. Since 2026 Polymarket charges a taker fee on most categories, while traders whose orders rest on the book pay nothing and can earn rebates. This guide covers the main exchange and the separate Polymarket US app, with worked examples, from Polymarket’s documentation as checked in October 2026.
How the fee is calculated
On the main exchange the fee is:
fee = shares × fee rate × price × (1 − price)
Because of the price × (1 − price) part, the fee is highest for trades at 50¢ and shrinks towards zero near 1¢ and 99¢. It’s charged in Polymarket’s dollar token, rounded to five decimal places, so very small trades at extreme prices can end up paying nothing.
Fee rates by category (main exchange)
| Category | Taker fee rate | Fee on 100 shares at 50¢ | Maker rebate |
|---|---|---|---|
| Crypto | 0.07 | $1.75 | 20% |
| Sports | 0.05 | $1.25 | 15% |
| Economics, culture, weather, other | 0.05 | $1.25 | 25% |
| Politics, finance, tech, mentions | 0.04 | $1.00 | 25% |
| Combos | 0.05 | $1.25 | None |
| Geopolitics and world events | 0 | Free | — |
The maker rebate is the share of collected taker fees paid back to makers in that category. Polymarket also runs a tiered rebate programme for high-volume takers. Sports rose from 0.03 to 0.05 in July 2026, so older articles quoting lower sports fees are out of date. Rates from Polymarket’s fee documentation and help centre, checked October 2026.
Worked examples
| Trade | Calculation | Fee |
|---|---|---|
| Buy 100 shares of a politics market at 50¢ | 100 × 0.04 × 0.50 × 0.50 | $1.00 |
| Buy 200 shares of a sports market at 80¢ | 200 × 0.05 × 0.80 × 0.20 | $1.60 |
| Buy 500 shares of a crypto market at 10¢ | 500 × 0.07 × 0.10 × 0.90 | $3.15 |
| Place a limit order that rests, then fills | Maker | $0, plus any rebate |
Taker vs maker: how to pay less
- Taker: your order fills immediately against an order already on the book, such as a market buy. You pay the fee.
- Maker: you place a limit order that waits on the book until someone else trades against it. You pay nothing, and you may earn a rebate.
If you’re not in a hurry, a limit order a cent inside the current spread often saves both the fee and the spread. The trade-off is that it may never fill.
Polymarket US fees
The CFTC-regulated Polymarket US app has its own schedule. Since October 19, 2026 its standard taker fee is:
fee = 0.0695 × contracts × price × (1 − price)
That’s $17.38 on 1,000 contracts at 50¢, in line with Kalshi’s standard rate. Table tennis carries a higher coefficient (0.10), combos use a separate formula, and makers earn rebates only above $10 million of monthly volume. Polymarket US’s fees have changed several times since launch, so check the fee preview before you confirm. Schedule from Polymarket US’s fee documentation, checked October 2026.
Deposit, withdrawal and gas costs
- Deposits and withdrawals: Polymarket charges nothing on the main exchange. The exchange, wallet or bridge you use may charge its own fee, and the withdrawal screen shows any third-party cost in its quote.
- Gas: Polymarket pays network gas for normal trading through its relayer, so you don’t need to hold POL.
- Polymarket US: deposits and withdrawals are described as free, though your bank or card provider may charge.

Polymarket vs Kalshi fees
Kalshi’s standard taker fee uses the same shape, 0.07 × contracts × price × (1 − price), so at 50¢ it’s $1.75 per 100 contracts, the same as Polymarket’s crypto rate and more than its politics or sports rates. Kalshi also charges a small maker fee on some markets. See Kalshi fees and our full Kalshi vs Polymarket comparison.
