NYSE and Blockchain.com Explore Tokenized U.S. Stocks Amid Regulatory Questions

NYSE and Blockchain.com announced a memorandum of understanding to explore providing tokenized U.S. equities and exchange‑traded funds (ETFs) to Blockchain.com’s global audience. The partnership aims to use NYSE’s planned digital alternative trading system (ATS) for on‑chain settlement, but many operational details remain undefined.

Scope of the Agreement

The September 23 memorandum covers access to tokenized shares and ETFs, subject to required regulatory approvals. It is a distribution agreement, not a launch of a live trading venue, and does not specify a launch date, eligible securities list, or country‑by‑country access rules.

Key Open Questions

• Ownership record: It is unclear whose ledger will serve as the definitive shareholder register when tokens are transferred.
• Trading eligibility: The criteria for which Blockchain.com users can trade tokenized securities have not been disclosed.
• Conversion mechanics: The process for converting a token back into a traditional share, including voting rights and dividend distribution, is not defined.

Regulatory Context

The SEC’s innovation exemption, announced on September 17, limits qualifying venues to 75 Tier 1 and 250 Tier 2 stock symbols and requires a 30‑day issuer notice for third‑party tokenized securities. The NYSE‑Blockchain.com plan must align with these requirements before any trading can commence.

Potential Custody Models

The SEC staff taxonomy outlines three possible models for tokenized securities:

1. Direct registration on the issuer’s shareholder file, where the token itself represents the legal share.
2. Off‑chain master file with the token acting as an instruction to update that file.
3. Third‑party synthetic token that tracks the share price but does not confer ownership rights.

Each model carries different implications for voting, dividends, and bankruptcy risk.

Related Developments

Earlier initiatives include:

• NY​SE’s digital ATS concept announced by Intercontinental Exchange, combining a Pillar matching engine with blockchain‑based custody and settlement.
• Securitize’s selection as a prospective digital transfer agent to mint blockchain‑native securities for issuers.
• DTCC’s July 15 pilot, where tokenized representations of assets held at DTC were traded on private and public networks, with a broader service slated for October.

Implications for Users

Consumers should verify the specific token model, identify the entity holding the underlying share, and understand which records are legally authoritative before engaging with tokenized stock products.
