Sweep the Floor

Overview

To sweep an NFT collection is to buy several listed items in one buying session, often selecting items near the collection’s lowest asking prices. A sweep is an execution choice; it does not certify that the NFTs are undervalued or that the collection will appreciate.

How a sweep works

A marketplace may let a buyer choose a quantity, price ceiling, or sort order and then submit purchases for multiple listings. OpenSea documents a collection sweep that selects listings according to the chosen sort and filter, with an optional maximum price per item. Whether the purchases settle in one transaction or several depends on the marketplace, collection contracts, and transaction route.

What happens to the floor

A collection floor price is the lowest current listing shown for that collection. Buying that listing can remove it from active listings, which may leave a higher-priced item as the new displayed floor. Other sellers can list lower items, and listings can be changed or cancelled; the floor can therefore move again. A higher displayed floor after a sweep does not establish a higher sale price, greater demand, or a lasting increase in value.

Costs and risks

Before confirming a sweep, review each selected item and its price, the total cost, marketplace fees, network fees, and the transaction summary. Filters and sorting affect which items are selected. Listings may change before execution, and a bulk purchase can concentrate exposure to one collection. A sweep can be used for ordinary collecting or trading; claims of manipulation or intent require evidence about the conduct and context.
