How are fees calculated?
Fee Calculation for Sports Markets
Fees for taker orders in Sports markets are calculated using the following formula:
fee = C × p × feeRate × (p × (1 − p))^exponent
Where:
C: Number of shares traded
p: Price of the trade
feeRate: 0.03
exponent: 1 For example, for a 100-share trade at a price of $0.50:
fee = 100 × 0.50 × 0.03 × (0.50 × (1 − 0.50))^1 fee ≈ $0.38
This represents the peak effective fee at the 50/50 price point.
Fees change based on the share price: The fee is highest when a share is priced at 50¢ (a 50% probability). The maximum effective fee rate is 1.80% at 50% probability.
Fees drop at the extremes: As a share's price gets closer to 1¢ or 99¢, the fee gets smaller and smaller.
Fees are rounded to 4 decimal places. The smallest fee charged is 0.0001 pUSD. Anything smaller rounds to zero, so very small trades near the extremes may incur no fee at all.
