In a letter to SEC Commissioner Hester Peirce, OpenSea argued that NFTs usually have only one seller per token — so platforms like theirs don’t function like traditional stock exchanges or brokers. They emphasized that all NFT transactions happen on-chain via smart contracts, with OpenSea simply acting as a discovery tool—not an intermediary, custodian, or advice-giver. To avoid future confusion, OpenSea is asking the SEC to issue clear guidance, like a bulletin or interpretive release, to confirm NFT marketplaces aren’t covered by exchange rules. This push follows OpenSea’s brush with a Wells notice last year—though the SEC dropped the investigation in early 2025 after President Donald Trump told the agency to pause crypto enforcement.
