Limit order: An order to buy or sell at your price or better; on Kalshi any part that does not match right away rests on the order book until filled or canceled.
A limit order sets the worst price you accept. Kalshi's help center says it lets you specify the maximum price you are willing to pay, and that there is no guarantee it will be filled. Kalshi's rulebook fills orders on an "or better" basis: a buy limit above the best offer fills at the better offers first, and any unfilled part stays in the book as a resting order at your limit price.
Example: the best Yes ask is 45¢ with 300 contracts behind it. You place a limit to buy 500 at 45¢. 300 fill now at 45¢; the other 200 rest as a bid at 45¢ until someone sells to you or you cancel. Kalshi's help center describes this partial fill case directly.
Fees depend on how it fills: Kalshi charges trading fees on orders that match immediately, and resting orders pay no trading fee unless the market is listed with maker fees. Through Kalshi's API an order can be good till canceled, immediate or cancel, or fill or kill, and can be marked post only.
