Wash Trading
Trading in which the same person or coordinated group effectively takes both sides to create misleading activity without meaningful economic ownership changing.
Wash trading occurs when one person, entity, or coordinated group is effectively both buyer and seller, so trades create apparent volume or price activity without meaningful economic ownership changing. Related accounts, wallets, or intermediaries can obscure that common control.
The goal may be to attract other traders, influence a displayed price, qualify for venue rewards, increase an NFT collection's reported volume, or support a broader manipulation scheme. Fees and price risk can make the activity costly even when the operator controls both sides.
Warning signals include rapid round trips, repeated matching sizes and times, common funding sources, self-trade patterns, and volume that is inconsistent with order-book depth or user activity. These are signals, not proof: market makers and automated strategies can also produce repeated trades for legitimate reasons.
Legal and venue treatment depends on the asset, conduct, and jurisdiction. Many regulated markets and trading venues prohibit wash trades, but a specific case requires evidence and the applicable rules.
