How Much Does KALSHI Take? KALSHI Fees Explained
how much does kalshi take is a common question for traders evaluating Kalshi, the CFTC-regulated event market. This article breaks down how fees are charged on every trade, what parts of a Kalshi position incur costs, and how you can estimate your true cost per contract before you place an order. You’ll also see how KalshiArb’s alerting helps you spot edge opportunities after fees. The goal is to give you a clear picture of the cost structure so you can plan your YES and NO trades with realistic expectations.
What drives Kalshi's trading fees
Kalshi charges a trading fee on each filled order. The fee is calculated per contract and applies to both sides of a binary market, meaning YES and NO trades incur the same per-contract cost. The exact amount depends on the price you trade at and the number of contracts you place. In practice, prices near the middle of the range carry higher per-contract fees than edges where price is far from 50 cents. The fee structure is designed to be predictable and is published by Kalshi; plan for the per-contract cost to be a function of price and size rather than a flat flat-rate.
Where fees apply: YES, NO, and spreads
On a standard binary Kalshi market, every contract has a YES side and a NO side whose prices sum to $1.00 in fair value. When you buy both legs to lock in an edge, fees apply to each leg independently. Even if you hold a balanced pair, you’ll incur two per-contract fees (one for YES, one for NO). This is important when you’re evaluating intra-market arbitrage opportunities where the combined cost of both sides reduces the guaranteed edge. KalshiArb users often watch the YES-ask and NO-ask together and subtract the expected total fee from the gross edge to determine profitability.
How to estimate costs for a trade
To estimate costs, you multiply the per-contract fee by the number of contracts and consider the price of each side. Because the fee varies with price and volume, a quick rule of thumb is to anticipate higher fees as you approach the 50-cent midrange. There is no maker rebate on standard markets, and the fee applies to both makers and takers. For precise numbers, check the live market data for the specific ticker and refer to Kalshi’s rulebook or market page which shows the current fee per contract at the moment you place an order.
Edge after fees and how KalshiArb helps
Intra-market edge strategies rely on the difference between best-ask prices and the 1.00 settlement asset. After subtracting the per-contract fees on both legs, the remaining guaranteed profit (edge) may still exist if the total ask prices are below $1.00. KalshiArb surfaces these opportunities with YES + NO < $1.00 alerts, helping you decide when to place a paired order. Remember, the final edge also depends on slippage, partial fills, and network latency, so incorporate those risks into your planning.
