## Taker Fee Structure
Taker fees are calculated in USDC and vary based on the share price. However, fees are collected in shares on buy orders and USDC on sell orders. Fees are highest at 50% probability and lowest at the extremes (near 0% or 100%).
Taker fees are calculated in USDC and vary based on the share price. However, fees are collected in shares on buy orders and USDC on sell orders. The fee amount in USDC is symmetric around 50% probability — a trade at 30¢ incurs the same dollar fee as a trade at 70¢.

## Upcoming Fee Structure
**Effective March 30, 2026**, fee parameters are expanding to cover more market categories with updated rates.
## Fee Structure
Fees are calculated using the following formula:
```text theme={null}
fee = C × p × feeRate × (p × (1 - p))^exponent
fee = C × feeRate × p × (1 - p)
```
Where **C** = number of shares traded and **p** = price of the shares. The fee parameters differ by market category:
Where **C** = number of shares traded and **p** = price of the shares.

**Makers are never charged fees.** Only takers pay fees. The fee parameters differ by market category:
Taker fees are calculated in USDC and vary based on the share price. However, fees are collected in shares on buy orders and USDC on sell orders. The effective rate **peaks at 50%** probability and decreases symmetrically toward the extremes.

Taker fees are calculated in USDC and vary based on the share price. However, fees are collected in shares on buy orders and USDC on sell orders. The fee amount in USDC is symmetric around 50% probability — a trade at 30¢ incurs the same dollar fee as a trade at 70¢.

**Effective March 30, 2026**, fee parameters are expanding to cover more market categories with updated rates.
## Fee Structure
Fees are calculated using the following formula:

fee = C × feeRate × p × (1 - p)
```
Where **C** = number of shares traded and **p** = price of the shares. The fee parameters differ by market category:

### Fee Precision
Fees are rounded to 4 decimal places. The smallest fee charged is **0.0001 USDC**. Anything smaller rounds to zero, so very small trades near the extremes may incur no fee at all.
Fees are rounded to 5 decimal places. The smallest fee charged is **0.00001 USDC**. Anything smaller rounds to zero, so very small trades near the extremes may incur no fee at all.
