Floor Price
The lowest listing price across a given NFT collection on a marketplace — the most-cited proxy for the collection's market value.
An NFT collection has thousands of unique items, each with its own sale price. The "floor" is the cheapest one currently listed for sale — the price at which you can buy the cheapest NFT in the collection right now.
Floor price is the closest analogue NFTs have to a spot price for fungible tokens, but it is also gameable: a single low listing pulls it down, a thin floor wash-trades up, and the floor item is by definition the worst-attribute item in the collection.
