NFT marketplaces can generate revenue through various models, including transaction fees, listing fees, premium subscriptions, and featured listings. Transaction fees, often a percentage of the sale price, are a common revenue source. Listing fees can be charged for artists or collectors to list their NFTs on the platform. Premium subscriptions can offer enhanced features or exclusive access for a monthly or annual fee. Featured listings can be sold to artists for increased visibility and exposure.
