Market order: Kalshi's Quick Order: buy a set number of contracts right away at the best prices available, which can fill across several price levels.
Kalshi calls it a Quick Order. Its help center says a Quick Order, also known as a market order, is a request to immediately buy a specific number of contracts at the best available price, and that it executes with no delay. You choose the quantity and the side, Yes or No, and Kalshi fills you as cheaply as the order book allows.
Kalshi's example: 500 Yes contracts are offered at 10¢ and more at 12¢. A Quick Order for 1,000 buys 500 at 10¢ and 500 at 12¢, an average of 11¢, which the order panel shows automatically. That extra 1¢ over the best price grows with order size and with thin books.
A market order always matches immediately, so it pays the trading fee that Kalshi charges on immediately matched orders. What to check: the average price in the order panel, the depth behind the best ask, and whether a limit order at your price would do. Kalshi View's slippage calculator estimates the average fill for a given size.
