NYSE Texas filed Rule 7.39 with the SEC on May 5 to allow tokenised versions of Russell 1000 stocks and major-index ETFs to trade alongside their traditional shares. The exchange used a procedural shortcut that made the rule effective on filing.
NYSE Texas filed a rule change with the Securities and Exchange Commission on May 5 to allow tokenised versions of stocks and ETFs to trade on its exchange under the same order book as the traditional shares. The notice was published in the Federal Register the same day, with immediate effectiveness — meaning the rule is already operative while the SEC retains the right to suspend it.
The proposed Rule 7.39 lets a security trade on the exchange in either traditional form or tokenised form, where tokenised means a digital representation of ownership on a blockchain. The filing covers the duration of a three-year tokenisation pilot operated by the Depository Trust Company, which received a no-action letter from SEC staff on December 11, 2025.
Nothing about the share itself is supposed to change. A tokenised version must be fungible with its traditional counterpart, share the same CUSIP number and ticker symbol, and afford the same shareholder rights; settlement still runs through DTC on a T+1 basis, and execution priority on the order book is identical. The blockchain layer is bolted onto the existing plumbing rather than replacing it.
At launch, eligible securities include Russell 1000 constituents and ETFs that track major indices. NYSE Texas said it will notify members at least thirty days before tokenised trading actually begins, so the rule's immediate effectiveness is more about positioning than about flipping a switch.
The May 5 filing follows a parallel push from the parent NYSE board, which lodged a similar proposal on April 9 (file number SR-NYSE-2026-17). Public comments on that filing close on May 13. The SEC approved a corresponding Nasdaq proposal in March, giving the agency a template that the NYSE entities are now matching with their own variants.
For the exchange, the appeal is defensive as much as offensive. Tokenised equity trading is already happening offshore — Mantle and Bybit listed tokenised Tesla and Nvidia exposure to crypto users last month, and Securitize has tokenised Currenc Group's Nasdaq-listed shares on Ethereum and Solana. None of those venues clear through DTC. If US exchanges do not offer a regulated on-chain alternative, retail flow that wants 24/7 settlement and self-custody will keep leaking to crypto rails the SEC does not directly supervise.
The DTC pilot is the regulator's answer to that drift. By keeping tokenised shares fungible with traditional ones — same CUSIP, same rights, same settlement — the framework treats the blockchain layer as a presentation format rather than a separate asset class. That avoids the question that has hung over crypto-native tokenised stocks for years: are these securities, securities derivatives, or something the law has not classified yet?
There are still gaps. The pilot is three years long, which gives the industry a runway but no permanent regime. Settlement remains T+1, despite the technical capacity for atomic settlement on most modern blockchains. And the proposal does not specify which blockchain DTC's tokenised securities will live on, leaving an infrastructure question that will eventually have to be answered.
Citadel Securities has already objected to the broader tokenisation push, arguing that letting crypto-native venues list tokenised equities outside the existing securities framework would fragment liquidity and harm price discovery. The Blockchain Association pushed back, calling the existing framework adequate. NYSE Texas's filing sidesteps that fight by staying inside the framework — its tokenised shares trade in the same book as the traditional ones, with identical priority.
The bigger commercial story is who builds the infrastructure underneath. Bullish announced a $4.2 billion deal to acquire transfer agent Equiniti hours before NYSE Texas's filing went live, an explicit play to own the issuance and registry layer for tokenised securities. State Street is building tokenised fund servicing in Luxembourg. BlackRock is fighting the OCC over how much of a stablecoin's reserves can be held in tokenised form. Each piece of infrastructure assumes the regulated tokenised-equity market the DTC pilot is meant to enable.
NYSE Texas, which the parent group launched as a fully electronic exchange after relocating NYSE Chicago to Dallas in 2025, is a useful vehicle for the experiment. It carries the NYSE brand and SEC oversight without the full institutional weight of the main board, which lets the operator iterate faster on the technical implementation. If the pilot extends or becomes permanent, the rules now in place at NYSE Texas can be ported across.
Comments on the immediate-effectiveness filing are still open, and the SEC can suspend the rule within sixty days if it identifies a problem. For now, the regulatory door is open and the exchange has walked through it. The question is which Russell 1000 issuer will be the first to opt into a tokenised share class — and how long DTC takes to get the on-chain settlement infrastructure ready to serve them.
