What it actually costs to cross size.
Slippage plus taker fee, measured on live books.
All-in = slippage + taker fee. Maker fees are not included. Kalshi opens at its best tier (1 bp taker) and the other venues at their default rate; set any venue's tier below.

Kalshi pays variable interest on position value to US accounts. The current rate could not be read just now, so none is credited above. The others credit nothing on the margin backing an open position: Hyperliquid pays only on idle USDC under opt-in portfolio margin, and Binance and Bybit pay only through opt-in wrapped collateral (BFUSD/LDUSDT, BYUSDT). Those pay on the margin posted rather than on position value, so at 5× leverage a headline 11% is worth about 2% against the exposure it backs.
