Combo (parlay) fees on Polymarket US
A combo pays $1 only if every leg wins, and it is charged on a steeper curve than a single market: contracts × price × [rate × (1 − price) + 0.06 × (1 − price)^4]. The extra term is largest on cheap combos, which is where most parlays are priced. The fee is taken once on the combo’s price, not once per leg.
| Combo price | Taker, Tier 1 | Taker, Tier 4 | Maker | Single market, Tier 1 |
|---|---|---|---|---|
| 5¢ | $0.70 | $0.57 | $0.14 | $0.45 |

Polymarket fee questions
How are Polymarket US fees calculated?
The taker fee is rate × contracts × price × (1 − price), rounded to the nearest cent. The rate depends on your taker volume over the last 30 days: 0.095 under $10,000, 0.085 $10,000 to $50,000, 0.075 $50,000 to $250,000, 0.0695 $250,000 or more, and 0.0695 for a new account’s first 7 days. 100 contracts at 50¢ cost $2.38 in fees at Tier 1 and $1.74 at Tier 4.
What changed in Polymarket US fees on November 14, 2026?
Before that date every taker paid the same rate, 0.0695. Now that rate is only for accounts that traded $250,000 or more in the last 30 days and for new accounts in their first 7 days. An account under $10,000 pays 0.095, about 37% more in fees on the same order.
What do new Polymarket US accounts pay?
The lowest rate, 0.0695, for the first 7 days counting from the day of the first filled order. From day 8 to day 30 the tier comes from the first week’s volume scaled to a month (or the real 30-day volume if higher), and from day 31 on from the last 30 days.
Does Polymarket US charge more on parlays?
Yes. A combo is charged on its own curve: contracts × price × [rate × (1 − price) + 0.06 × (1 − price)^4]. 100 combo contracts at 25¢ cost $2.26 at Tier 1, against $1.78 for a single market at the same price. The fee is charged once on the combo, not on each leg.
Do makers pay fees on Polymarket US?
Not on single markets: a resting order that gets filled pays nothing, and accounts with $10 million or more of 30-day maker volume earn a small rebate. On combos the maker pays 0.03 × contracts × price × (1 − price).
Is Polymarket US cheaper than Kalshi?
On fees alone, only at the top tier. Kalshi charges 0.07 × price × (1 − price) to everyone. Polymarket US at Tier 4 (0.0695) is a hair lower; at Tier 1 (0.095) it is about 36% higher. The price itself matters more than the fee, which is why Oddy compares both after fees on every game.
Is a fee charged if my order does not fill?
No. Fees are charged only when a trade executes; a canceled, expired or rejected order costs nothing. Small trades can also round down to no fee at all.
