NFT Marketplace Legal Structuring: The SEC Backed Off, But Two Traps Remain

The good news arrived quietly

In February and March 2025, the SEC closed its investigations into OpenSea and Yuga Labs without recommending enforcement action — after years of the opposite posture. By June 2026, joint SEC–CFTC guidance had gone further, carving out an explicit "digital collectibles" category for things designed to be collected or used: artwork, music, in-game items. The EU's MiCA had already made the same call by design — Article 2(3) excludes crypto-assets that are "unique and not fungible with other crypto-assets" from the regulation entirely.

Read as a headline, that sounds like NFT marketplaces got a clean bill of health. Read the actual text, and two exceptions carry real weight: fractionalise the NFT, or let money pool inside your platform, and the exemptions above stop applying to you specifically.

Where "unique" stops being unique

MiCA's exclusion hinges entirely on the word "unique." The moment an NFT is divided into fungible fractions, each fraction is a crypto-asset under MiCA, full stop. Less obvious: a "unique" collection can lose that status collectively. Large series or collections with substantially similar characteristics can be deemed fungible even when every individual item is marketed as one-of-one — the regulation looks at economic substance, not the marketing copy.

And if the underlying asset represented by the NFT is itself a security, a derivative, or a structured deposit, the token is a financial instrument under MiFID II regardless of how it's labelled. One industry assessment puts roughly half of fractionalised-NFT structures it reviewed on the wrong side of that line once tested — treated as securities rather than unique collectibles. That's one analyst's read, not a regulator's ruling, but it's directionally the right level of caution: fractionalisation is the design choice most likely to drag a "collectible" into full MiCA or securities-law compliance.

The money transmission trap

This one has nothing to do with what the NFT represents and everything to do with how payment moves through your platform.

A non-custodial marketplace — wallet to wallet, users holding their own keys throughout — generally doesn't trigger money transmitter licensing in the US. The moment money passes through your platform instead of around it — a pooled account, a merchant account you control, any stored-value balance held on a user's behalf — most US states will consider that money transmission, full stop, independent of whether the NFT itself is a security.

Stack a securities determination on top of that and the exposure compounds fast: a platform whose NFTs get classified as securities, commodities, or currency can find itself needing a broker-dealer registration, a commodity pool operator or broker registration, and a money transmitter licence in every state with customers on the platform — three separate regulatory regimes stacked on one product decision.

The entities that keep this separated

The operator that's exposed to the licensing questions above shouldn't be the same entity holding your brand and your code.

The Operating Co signs the user agreements, runs the marketplace, and — if your model requires it — holds any money transmitter or CASP-adjacent registration. This is the entity that carries the regulatory exposure described above, so it should be domiciled wherever that exposure is actually being managed, with nothing else of value sitting inside it.

The IP Co holds the trademarks, the marketplace software, and the brand — kept structurally apart from the operating entity so a licensing dispute or an enforcement action against the marketplace doesn't automatically reach the technology and the name. We cover the trade-offs of where to put this in our IP holding company guide — BVI and Cayman both work well here, for the same privacy and simplicity reasons they work for token issuance.

One more honesty note, since it trips up a lot of marketplace teams: on-chain creator royalties are a contractual expectation, not a guaranteed legal right. Several major marketplaces made royalty enforcement optional starting in 2022–23, and nothing in the code forces a competing marketplace to honour a royalty percentage set elsewhere. If royalty revenue matters to your model, it needs to be engineered — through allowlists, transfer restrictions, or contract — not assumed.

How Otonomos Helps

We structure the Operating Co and IP Co split above across the jurisdictions this guide references, with the KYC, charters and beneficial-owner filings each entity needs, and Nominee Directors where privacy matters. What we don't do is tell you your NFT collection definitely clears MiCA's "unique" test or definitely avoids money transmitter status — those are facts-specific calls that deserve a real legal opinion before you launch, not a guess based on a blog post.

FAQs

Do I need a licence to run an NFT marketplace in 2026?
Not automatically. A non-custodial marketplace trading genuinely unique NFTs, with no money pooling inside the platform, sits outside both MiCA and most US money transmitter regimes. The exemptions narrow fast the moment you fractionalise the NFT or take custody of user funds.

Are fractionalised NFTs still NFTs, legally?
Not under MiCA. Fractionalising an NFT into fungible pieces converts each piece into an ordinary crypto-asset, losing the "unique and non-fungible" exclusion entirely — and possibly triggering securities treatment if the underlying asset would qualify as one.

Does my marketplace need a money transmitter licence?
Only if money passes through your platform — a pooled account, a merchant account, or a stored balance you control. Pure wallet-to-wallet trading, where you never touch the funds, generally avoids this in the US.

Can Otonomos guarantee my NFTs won't be classified as securities?
No, and we'd be lying if we said otherwise. What we can do is structure your operating and IP entities so that if a classification question does arise, it's contained to the entity built to carry that risk — not spread across your brand, your code, and your treasury at once.

Are creator royalties legally enforceable?
Not reliably through the code alone. Several major marketplaces made on-chain royalty enforcement optional years ago, and no protocol can force a third-party marketplace to honour a royalty set elsewhere. Real royalty enforcement today is a contract and product-design problem, not a blockchain guarantee.
