Floor Price
The lowest asking price in an NFT collection — the entry cost, and the headline metric of a collection's value.
Floor price is the cheapest available listing in an NFT collection — effectively the minimum to own one, and the number most quoted to summarize a collection’s health. A rising floor signals demand; a collapsing floor signals fading interest, which for most collections has been the long-run direction after the 2021–22 mania.
Floor price is a crude gauge with well-known distortions: it can be propped up by wash trading, manipulated by a few listings, and ignores the wide value range within a collection (rare traits trade far above floor). Thin NFT liquidity means the floor can also be illusory — you may not actually be able to sell at it. Useful as a quick reference, unreliable as a precise valuation.
