Biggest NFT marketplaces worldwide, based on trade volume 2021-2023

OpenSea's role as the market leader for NFT trading came under increasing threat since 2022, and as of early 2023 platform Blur took over the role. This is according to tracking from blockchain explorer NFTGo.io, which investigated daily to hourly transactions made on the Ethereum blockchain for several NFT platforms. OpenSea is a well-known decentralized marketplace for NFT trading, and grew to prominence in 2021 as one of the main places to buy "crypto art" - digital art pieces sold via NFTs and were often paid for with cryptocurrency. Since then, several competitors launched that hoped to attract OpenSea's user base via low transaction fees and dedicated token drops. LooksRare and X2Y2 were initially successful in doing so, but neither matched the success of Blur. Blur, a platform launched in October 2022, announced a zero transaction fee policy and almost immediately attracted several times more trading volume than OpenSea.
