Kalshi Place Order

Place a new order on a Kalshi prediction market. Supports limit and market orders for buying or selling yes/no contracts. Prices are dollar strings (e.g. '0.6500'). For market orders, if no price is provided a conservative slippage cap is auto-applied (0.99 for buys, 0.01 for sells) on the active side — Kalshi requires a price even on market orders. Ideal for: automated trading, signal-based order placement, portfolio construction, prediction market strategies.
