The New York Stock Exchange (NYSE), owned by Intercontinental Exchange (ICE), has filed a rule change proposal with the U.S. Securities and Exchange Commission (SEC) seeking approval to list and trade tokenized versions of eligible equities and exchange-traded funds (ETFs). The proposal, dated May 3, 2026, marks a significant step toward integrating blockchain technology into traditional financial market infrastructure.
Under the proposed rule, which would create NYSE Rule 7.50 for Tokenized Securities and amend existing rules covering definitions, order display, ranking, execution, clearing, and settlement, the exchange seeks to allow member firms to trade tokenized securities that are fully fungible with their traditional counterparts. These tokenized shares would carry the same ticker symbol, CUSIP identifier, shareholder rights, economic exposure, and settlement framework as standard shares, with the only difference being the use of blockchain-based settlement on the backend.
The proposal relies heavily on a three-year tokenization pilot program run by the Depository Trust Company (DTC), authorized by an SEC staff no-action letter dated December 11, 2025. Only member firms that qualify as DTC Eligible Participants can use the system, and only assets designated as DTC Eligible Securities—approved equities and exchange-traded products—would be eligible. The NYSE explicitly states that the current rulebook does not permit tokenized securities to trade, so this change is required to create a clear regulatory path.
Importantly, the NYSE emphasizes that tokenized securities would trade within the existing National Market System, not on a separate blockchain venue. The order would still go through the NYSE's order book, and DTC would clear and settle trades in token form when an eligible firm opts for that handling at order entry. The exchange wants tokenized and standard versions of the same security to appear on the same order book, provided they are fully equivalent in all material respects.
The NYSE's move follows a similar earlier step by Nasdaq (NDAQ), which secured approval for a comparable framework. This signals a broader shift where top U.S. exchanges are adopting blockchain technology internally rather than being replaced by crypto. The NYSE argues that blockchain settlement does not require a separate market structure, broad exemptions, or new trading lanes, comparing it to historical changes like decimal pricing, electronic trading, and the introduction of ETFs.
Risks and challenges remain a central concern. The SEC notice requests public comments from investors, brokers, issuers, and market companies before moving forward. Key risks identified include: price volatility in secondary markets for tokenized assets, valuation difficulties when tokenization extends beyond listed shares, tax reporting complications due to differing regulations across countries, custody requirements for secure key storage, and potential incompatibilities with existing legal and operational infrastructure built over decades. The proposal acknowledges that tokenized assets may not fit every part of the current system, and some links may break under pressure.
For investors and traders, the potential benefits include lower settlement costs, reduced operational risks, faster transaction execution, simplified custody systems, and improved capital efficiency. For developers, the shift creates demand for tokenized asset issuance platforms, institutional custody solutions, compliance middleware, identity verification systems, and settlement APIs. The overall effect is expected to be a gradual integration of blockchain into mainstream finance, improving efficiency without replacing existing structures.
