SEC grants conditional exemption for tokenized-stock AMMs

The U.S. Securities and Exchange Commission on September 17 granted temporary, conditional relief for permissioned trading of tokenized U.S. exchange-listed stocks through automated market makers and liquidity pools. The order creates a path for qualifying Tokenized Securities Venues, or TSVs, to operate without being treated as exchanges, while certain liquidity providers can avoid dealer status for activity inside those pools.

Coinburn is publishing this recovery report on September 28. The event date remains September 17, and no development learned after the September 18 assignment date is used to describe what was known then.

The action matters because it imports a crypto-market trading design into regulated equity market structure. It does not authorize unrestricted decentralized trading, approve a particular venue or token, or remove the stocks from federal securities law.

Permissioned markets on public ledgers

A qualifying venue must be a U.S. person and must limit access to verified or credentialed participants. Its smart contracts, however, must be auditable, publicly available and deployed on a public, permissionless distributed ledger.

The eligible instruments are tokenized National Market System stocks: digital representations of covered exchange-traded shares. Synthetic products that merely track a stock, tokenized security-based swaps, rights and warrants fall outside the order. The venue cannot conduct a primary issuance. It must verify that each eligible token carries the same economic and governance rights as the equivalent conventional share, including dividends, voting rights and a residual claim in liquidation.

Third-party tokenization is possible, but an unaffiliated tokenizer does not get a silent route around the issuer. The venue must notify the underlying company, wait at least 30 calendar days and refrain from listing if the issuer objects during that period.

The SEC capped the experiment

The exemption is designed as a limited test, not a wholesale replacement for national exchanges or alternative trading systems. It expires five years after publication, and the Commission asked for public comment on possible changes and next steps.

For the most liquid Tier 1 group, a venue and its affiliates may trade no more than 75 symbols. Trading in each covered stock is capped at 0.25% of that stock’s average daily share volume during the prior month, measured from consolidated U.S. transaction-reporting plans. Tier 2 is capped at 250 symbols and 2.5% of the same prior-month measure. These percentages are regulatory ceilings, not evidence that any venue reached those volumes.

A TSV must publish dollar-denominated transaction data within 10 minutes and keep at least 30 days of data freely available in machine-readable form. It must halt a tokenized stock when the underlying stock is halted on its primary listing exchange. The order also bars the venue from extending credit for tokenized-stock purchases or hypothecating assets on the venue.

What changed, and what did not

The central change is a conditional exemption from two definitions that could otherwise require exchange or dealer registration for the specified model. Antifraud and antimanipulation rules continue to apply, as do other applicable securities-law requirements. The dealer relief is confined to covered proprietary liquidity provision in a qualifying pool.

The order therefore reduces one regulatory barrier without establishing that tokenized stocks will attract issuers, users or durable liquidity. Axios reported on September 17 that company receptiveness remained uncertain. The mandatory notice period also means the order did not itself put a new venue into production that day.

No price, return or realized trading-volume claim is made here. The reviewed record establishes the legal pathway and its limits; it does not establish market adoption, execution quality, settlement performance or a causal effect on cryptocurrency or equity prices.
