An NFT, or non-fungible token, is a blockchain token representing a unique, non-interchangeable item or right. Its regulatory classification depends entirely on what the underlying item or right is: a piece of digital art and a tokenized claim on a building can both be NFTs while sitting in completely different regulatory positions.
Non-fungibility is a technical property of the contract. The legal classification turns on what right the token confers, so conflating the two is the mistake that produces exposure after launch.
How it works
An NFT is unique and non-interchangeable: owning token ID 47 is categorically different from owning token ID 48. On Ethereum, the ERC-721 interface defines the ownership, transfer, and approval functions that wallets and marketplaces rely on. The non-fungibility is purely technical. The regulatory classification depends entirely on what right or claim the token confers, not on its structure.
Why it matters
MiCA carves out crypto-assets that are unique and not fungible from its main categories, since a one-of-a-kind artwork does not need the framework built for payment instruments. That carve-out has a boundary: when NFTs ship in large standardized collections with fractionalized economic rights, regulators treat them as functionally fungible and apply the matching framework. The real test is whether a reasonable holder would treat their token as interchangeable with another from the same collection, not whether the contract assigns different IDs.
Design consequence
In the US, the SEC has argued certain NFT collections were sold as securities, especially where marketing pushed price appreciation and buyers had little intent to use the underlying item. It is the same Howey analysis applied to a non-fungible instrument. An NFT whose value rests on an artist's reputation is analytically different from one whose value rests on the issuer's continued development of a game or platform.
Common mistake
Skipping the first question: state precisely what right the token confers. A right to display or resell a file, a right to access a service, a fractional claim on property revenue, and a membership benefit are four different instruments that happen to share the NFT structure. Each carries its own classification analysis. Treating the technical label as the legal instrument is what generates regulatory trouble after launch.
