Two Polymarkets, two fee rules
Polymarket US is the iPhone app for US residents, regulated by the CFTC and trading in dollars. Sign-up asks for your date of birth, phone number and Social Security number. Its fee changed on October 19, 2026 to 0.0695 × contracts × P × (1 − P), rounded to the nearest cent on each fill. That is almost identical to Kalshi’s taker fee.
Polymarket.com is the international site. It runs on crypto: you hold pUSD, a dollar token backed by USDC, in a wallet only you control. It charges takers only, at a rate set by the market’s category:
| Category | Taker rate | Fee on 100 shares at 50¢ |
|---|---|---|
| Crypto | 0.07 | $1.75 |
| Sports, economics, culture, weather, other, combos | 0.05 | $1.25 |
| Politics, finance, mentions, tech | 0.04 | $1.00 |
| Geopolitics | 0 | $0 |
The price you see isn’t always the price you pay
Polymarket displays the midpoint between the best bid and the best ask, or the last trade when the spread is wider than 10¢. A buy fills at the ask, so check the order book before you trust the headline number.

Does Polymarket charge to deposit or withdraw?

The whole method is in the book
These tools come from 62% Chance, a plain-English guide for beginners by Armando Acevedo, who spent 25 years setting prices for sportsbooks. It follows one new trader from her first look at a price to a tested plan: fees, the order book, borrowing a sportsbook’s sharp prices, bet size, scams, taxes and when to stop.
