Market order is a specific Markets coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: An instruction prioritizing immediate execution over a guaranteed price. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
Market order is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.
Market order describes how participants value, trade or obtain exposure to bitcoin. Market behavior can affect adoption and mining economics, but it does not rewrite consensus rules. Price evidence and protocol evidence answer different questions.
Understanding Market order helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
Primary or authoritative records make these details checkable: a market order requests immediate execution against available opposing quotes, prioritizing completion over a specified price; fills can occur across multiple levels and be partial under venue rules. They should be verified before using the coordinate in analysis.
The practical limit is: a market order does not guarantee the displayed price or even complete execution, especially in fragmented or fast markets; spread, depth, latency, price protection, fees and outages determine realized cost. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
