Wall Street's Tokenization Race: Could Blockchain Transform Stock Trading?

On September 17, 2026, the Securities and Exchange Commission issued a five-year conditional exemption that lets new trading venues handle blockchain-based versions of US-listed stocks. It is the clearest sign yet that tokenization is moving from pilot projects toward regulated markets.

The race has two tracks. Established exchanges and clearing institutions want to add blockchain to existing market plumbing. Crypto-native platforms want new venues that run alongside it.

What a tokenized stock is

A tokenized stock is a digital token that represents a real share, recorded on a blockchain. A January 28, 2026 statement from SEC staff said tokenization does not change a security's legal status. It also separated tokens backed by actual shares from synthetic products that only track a price.

Track one: upgrading the plumbing

The Depository Trust Company, part of DTCC, holds assets worth more than $114 trillion. In December 2025 it received SEC no-action relief to run a tokenization service for three years. DTCC processed its first production trades in tokenized form on July 15 and has said the service will launch in October 2026.

DTCC says its industry working group now has more than 100 members and partners. Early participants included BlackRock, Goldman Sachs, JPMorgan, Nasdaq and NYSE Group, along with the parent of crypto exchange Kraken, Yahoo Finance reported. The first phase covers Russell 1000 stocks, major index ETFs and US Treasuries.

Exchanges are building on top. The SEC approved Nasdaq's tokenized trading rule in March 2026 and the New York Stock Exchange's on April 17. Under Nasdaq's design, tokenized and conventional shares carry the same rights and trade on the same order book. DTC converts shares into tokens after settlement. NYSE's rule limits eligible securities at launch to Russell 1000 constituents and ETFs tracking major indices such as the S&P 500 and Nasdaq-100, and members get at least 30 days' notice before tokenized trading goes live. Nasdaq has said its approach is not exclusive and that other forms of tokenization remain under discussion.

That design is deliberately conservative. Tokenized shares still trade through brokers and settle through DTCC, with the blockchain acting mainly as an alternative record of ownership, CoinDesk reported.

Track two: a new kind of venue

The September exemption creates a category called Tokenized Securities Venues. Through September 17, 2031, they can trade tokenized stocks using permissioned automated market makers and liquidity pools without registering as exchanges.

Conditions apply. Tokens must carry the same dividend and voting rights as the underlying shares, synthetic tokens are excluded, and trading must halt when the underlying stock halts. Issuers can object, according to law firm Cooley's reading of the order. SEC Chairman Paul Atkins described the order as a "bridge toward durable rulemaking."

NYSE has separately outlined plans for a dedicated venue offering 24/7 trading, instant settlement, orders sized in dollars and stablecoin funding, according to a law firm summary of its filing.

What could change

DTCC says tokenization can make collateral move faster and improve capital efficiency. Backers also point to longer trading hours and orders sized in dollars rather than whole shares. Nasdaq plans to launch 23-hours-a-day, five-days-a-week trading of conventional shares on December 6, 2026.

Settlement speed is less clear. In Nasdaq's model, a token can move instantly after settlement, but the trade itself still clears on a T+1 cycle, Forbes reported.

What remains unresolved

Liquidity could split. Forbes described the likely outcome as two markets for the same company: one tied to Nasdaq and DTCC with full shareholder rights, and another on crypto-native rails.

The new venues may operate outside Regulation NMS, the rules that link US stock markets, subject to conditions and caps, law firm Sidley noted. DTCC will launch on two blockchains, Canton and Besu, according to reporting, which raises questions about how tokens move between networks.

The permissions are also temporary. DTC's letter runs three years and the exemption five. Cooley noted that market-structure legislation has stalled, which is why the SEC is acting through exemptions.

What it means

For now, tokenization is mostly a plan for the infrastructure behind trading, not something most investors will see on their screens. The tests ahead are DTCC's launch, the first venues to file notices under the exemption, and whether regulators turn temporary relief into permanent rules.

Whether blockchain transforms stock trading will depend less on the technology than on whether those tests deliver real gains in cost, speed and investor protection
