Like buying something at the listed price in a store without negotiating, a market order executes instantly at the best available price.

Advanced Definition

Market orders are trading instructions to buy or sell an asset immediately at the current market price. They guarantee execution speed but not the exact price, as the final transaction price depends on the available liquidity and current order book state.
