Tokenizing a ticker is the easy part. Keeping the resulting instrument synchronized with the legal record of who owns the underlying security is where the plumbing gets interesting.

That is the premise behind the Issuer Sponsored Token Coalition announced on September 24 by Bullish and Equiniti. Alpaca, Apex Fintech Solutions and DriveWealth are among its first market-infrastructure participants. The group says it will work on a model in which tokenized public securities remain connected to an issuer's authoritative shareholder register.

The distinction matters because products commonly described as tokenized stocks do not all represent the same thing. Some structures can provide exposure to a share price through a wrapper or synthetic instrument without making the holder a shareholder of the underlying company. The coalition is focused instead on issuer-sponsored securities designed to preserve rights associated with the traditional share, including voting, dividends and corporate actions.

The SEC just made the ownership question harder to ignore

The announcement comes one week after the U.S. Securities and Exchange Commission issued its Innovation Exemption for tokenized NMS stocks. The temporary conditional framework allows limited onchain trading through qualifying Tokenized Securities Venues and automated liquidity pools.

One condition is particularly relevant here: a venue must verify that a tokenized NMS stock gives its holder the same rights and privileges as the equivalent class of traditional stock. The SEC also created a process for issuers to object when an unaffiliated third party wants to make a tokenized version of their shares available through one of those venues.

The relief lasts five years and comes with limits and additional operating requirements. It is therefore not a blanket declaration that every blockchain product tracking a listed company has suddenly become interchangeable with the company's stock.

That leaves a technical problem sitting underneath the regulatory one. If the share can exist in conventional book-entry systems and on a blockchain, market infrastructure needs a reliable way to determine which record is authoritative, process transfers, handle corporate actions and keep the different rails synchronized.

The coalition is mostly about market plumbing

Its initial work is divided into four broad areas: preserving issuer and shareholder rights, creating interoperability, building infrastructure for adoption and expanding an open ecosystem of market participants.

The group expects that work to include blockchain and smart-contract architecture, common operational standards, custody, settlement, secondary trading and regulatory requirements. It also plans to examine how issuer-sponsored securities might move between conventional market infrastructure, blockchain networks, wrapped-token structures and emerging entitlement-token systems.

Each founding participant arrives from a different part of that chain. Alpaca operates brokerage infrastructure and has been building its Instant Tokenization Network. Apex provides clearing and technology to financial firms. DriveWealth supplies brokerage infrastructure. Bullish operates digital-asset trading infrastructure, while Equiniti sits much closer to the legal ownership record through its transfer-agent business.

There is no production standard to point to yet. Membership in the coalition is non-binding, and joining does not commit a participant to list a security, issue a product, provide liquidity or enter into a commercial agreement. Product prototypes and pilots are among the work the coalition expects to explore rather than services it claims are already available.

That distinction is useful. Crypto infrastructure announcements have a habit of making a working group sound suspiciously like a finished network. This one still has a fairly long list of synchronization, compliance and market-structure problems to solve.

Bullish is already testing the issuer-sponsored model on itself

The project also aligns neatly with Bullish's existing tokenization strategy. In May, the company announced that BLSH ordinary shares could be held as tokens on Solana while Equiniti maintained the official ownership record. In August, Bullish launched trading of its tokenized shares for market participants on its Gibraltar-regulated exchange.

Bullish has also agreed to acquire Equiniti for $4.2 billion. The deal is still pending and is expected to close in January 2027, subject to regulatory approvals and customary closing conditions. If completed, Bullish would combine exchange and tokenization technology with a transfer agent that already maintains shareholder records for thousands of issuers.

The coalition effectively expands that architecture beyond one company's cap table. Brokers need to interact with it. Custodians need to know what they are holding. Trading venues need consistent rules. Corporate actions have to reach the correct owner. Traditional and blockchain settlement systems cannot independently decide that each is the definitive copy of the same share.

Coalition members are scheduled to meet issuers and other capital-markets participants at the New York Stock Exchange on October 27. The agenda announced for that meeting centers on how public companies can approach tokenization and what infrastructure would be needed to connect issuer-sponsored onchain securities with existing markets.
