The US Securities and Exchange Commission has opened the door for American listed stocks to trade on public blockchains, approving a temporary Innovation Exemption that lets approved venues run tokenized versions of National Market System stocks on automated market makers instead of the traditional order book. The order, effective since September 17, runs for five years and comes with a request for public comment as the agency weighs permanent rules for the fastest-growing corner of tokenization.
The relief covers venues the SEC calls Tokenized Securities Venues, or TSVs. Each one can trade tokenized NMS stock, meaning shares that already trade on the national exchanges, once those shares have been wrapped into blockchain tokens either by the issuer or by an unaffiliated third party. Trading happens through permissioned automated market makers and liquidity pools, a mechanism familiar from decentralized finance but here confined to a closed set of approved participants, which is why the SEC argues the venues do not meet the statutory definition of an exchange under the Securities Exchange Act of 1934 while the exemption lasts. The order grants two forms of relief, one from the exchange definition for the venues and a companion relief for the liquidity pool systems themselves.
Restrictions are tight. Tokenized stock on a TSV can only trade in pairs with another tokenized NMS stock, a non-security crypto asset such as a GENIUS Act payment stablecoin, or a tokenized money market fund. Primary issuance is off the table entirely: no fund can raise money by selling tokenized shares through the venue. Commissioner Mark Uyeda, speaking at the approval, described the programme as deliberately contained, with symbol and volume caps, transaction transparency requirements, recordkeeping duties and technology safeguards built in so the agency can study how on-chain markets behave before writing permanent rules. He said the framework would give the commission data to assess on-chain securities trading and inform whatever rules come next.
Why it matters for crypto rails
Tokenization has spent years as a pitch deck concept with only fragments in production, mostly private funds and money market tokens limited to qualified investors. The exemption changes the addressable market in one step, because the US listed equity universe includes the largest companies in the world and the deepest pools of retail order flow. Bitwise and other analysts had already tallied tokenized real-world assets in the tens of billions globally, the bulk of it in US Treasury and private credit tokens, so opening the equity universe adds a class of assets most investors actually own. For the crypto industry, the order validates a specific architecture, the automated market maker, as compliant infrastructure for regulated securities when wrapped inside permission controls. Exchanges and DeFi platforms that spent 2025 building tokenization pilots against an uncertain legal backdrop now have concrete information about what the SEC will tolerate.
The agency itself framed the move as an experiment rather than a destination. Chairman Paul Atkins has said the exemption must be followed by durable rulemaking, and the public comment window attached to the order is meant to gather data on how permissioned pools, pricing and transparency controls perform with real securities. Atkins had signalled the direction in February, saying the regulator was weighing a temporary framework for tokenized securities traded through automated market makers, so the September order lands on a timeline the market had been able to price in. Law firm analyses from Sidley Austin and Morrison and Foerster note the order is conditional throughout, meaning revocation triggers stay available if the programme produces the kind of misconduct the controls were designed to prevent.
What the market watches next
The intermediary question is still open. Tokenized NMS stock will mint on rails such as the Ethereum ecosystem, where most institutional tokenization pilots already sit, but the venue layer, the actual TSVs, has yet to be settled because the order lets venues apply rather than naming them. Broker-dealers, crypto-native exchanges and traditional market makers are all plausible applicants, and the pairing rules create a niche for tokenized money market funds as settlement assets on whichever venues get approved. On the demand side, the combination of US equities with around-the-clock crypto trading hours remains the feature retail platforms have wanted for two years, and the caps in the exemption are the agency’s answer to concerns from trade groups about how quickly that capability could scale before permanent rules exist.
The fee and liquidity structures of AMM pools are where the experiment will prove or fail. Order books reward precise price improvement, AMMs price by formula, and the gap between the two costs money on every trade. If tokenized bellwethers such as Apple or Nvidia trade on-chain with acceptable slippage, the pressure for permanent rulemaking grows quickly. If spreads stay wide, the incentive for the exchange status quo to resist change grows with them. Either way, the five-year clock and the caps mean the SEC reviews real evidence instead of theories when it drafts the durable rules that follow, and participants get to build against a named set of constraints for the first time in the tokenization debate.
Overseas regulators are watching the same experiment from the other side. Hong Kong’s securities commission had already allowed licensed platforms to list tokenized securities in a controlled regime, and the EU’s MiCA framework gives asset-referenced tokens a rulebook the US has been assembling piece by piece. If the American experiment shows that permissioned pools can trade real equities without the investor harms sceptics predicted, the argument for similar relief elsewhere strengthens. If it stumbles, the controls in the SEC order become a checklist of what went wrong rather than a template. Either outcome gets recorded, because the transparency and recordkeeping requirements turn the entire programme into a dataset the agency can mine for its final rules.
