The collectibles market in the sports world was one of the first to embrace the new Web3 technology of Non-Fungible Tokens (NFTs). NFTs are digital assets with a record of ownership stored permanently on a blockchain. The creation of NFT-based and blockchain-powered NBA Top Shot by Dapper Labs in 2019 brought a peer-to-peer online marketplace for tradable digital collectibles to sports fans everywhere, reportedly generating some $1 billion in total sales already. Tradable digital assets can represent memorable moments in sport in the form of images, music or video clips, authentic player-owned assets, and countless other marketable artifacts. Trading in sports-related NFTs is fueling rapid growth in the broader sports memorabilia market, already accounting for some $2 billion within the overall $26 billion market.
