OpenSea

The company operates a multi-sided NFT marketplace that connects creators, collectors and traders of digital assets. It creates value by aggregating NFT listings, providing discovery and transaction infrastructure, and concentrating liquidity so assets can be traded more efficiently. On the technical side, it offers developer APIs and an open-source protocol that external developers and marketplaces can use to access NFT data and execute orders.

Revenue is generated predominantly via a platform fee charged as a percentage of transaction value on trades executed through its marketplace interfaces (web and API). The company also supports creator royalties, which route a share of proceeds to NFT creators but are distinct from the platform’s own fee. Additional value is created for developers through access to marketplace data and order flow via APIs and SDKs, which reinforce the core marketplace by driving more integrations and volume.

The company generates revenue primarily through a percentage fee on NFT transactions executed on its marketplace, with optional creator fees routed to NFT creators. Its customers are NFT collectors, traders, and creators using the marketplace for primary and secondary sales, as well as developers and marketplace builders integrating its APIs and protocol for programme-matic access to NFT data and trading functionality.
