What it means
Trading fees are what the exchange charges when your order fills. On Kalshi they depend on the price and number of contracts, and are highest near 50¢.
Example
Kalshi's general taker fee is about 0.07 × contracts × price × (1 − price), rounded up to the next cent. For 100 contracts at 50¢ that's about $1.75.
Practical tip
Fees can turn a small edge into a loss. Always include them in your EV, and check Kalshi's fee page because some markets use different rates.
