Wall Street May Embrace Tokenized Stocks, But Not on Public Blockchains

Many crypto enthusiasts dream of trading traditional equities around the clock on public blockchains. They imagine a decentralized utopia where anyone can buy fractional shares of major corporations without traditional brokers.

This vision fundamentally misunderstands how institutional finance operates. In my opinion, major tokenized stocks will never migrate to public networks. The future of twenty-four-hour equity trading belongs exclusively to private or semi-private blockchain architectures.

Regulatory Signals Fuel the Narrative

The United States Securities and Exchange Commission recently proposed rescinding two key rules under Regulation National Market System.

These rules require trades to be routed to the national best price and prohibit locked or crossed quotes across venues. Analysts like Alex Thorn note that automated market makers on public chains conflict with these requirements because they execute against isolated liquidity pools without checking off-chain quotes. Removing the rules could theoretically open the door to compliant on-chain trading of tokenized United States equities.

However, this remains a medium-term structural adjustment rather than an immediate green light. The proposal still faces a lengthy comment process, and platforms would still need to register as exchanges or alternative trading systems, satisfy clearing obligations, and ensure token holders retain voting and dividend rights.

Traditional market groups also warn that removing the rules could reduce price transparency and fragment markets.

Operational Constraints of Public Blockchains

Even with favorable regulations, public blockchains present significant operational hurdles for institutional equity trading. Gas fee volatility remains a primary deterrent. A surge in retail activity can congest public networks and sharply increase transaction costs.

Institutions cannot risk large equity settlements being delayed or becoming more expensive because of unrelated retail traffic. Traditional finance requires deterministic execution.

A bank executing a large block trade needs certainty around cost and settlement timing. Institutional traders require millisecond precision and reliable finality. Public networks prioritize openness and censorship resistance over the predictable throughput global capital markets demand.

Maximal Extractable Value (MEV) presents another critical barrier. Public blockchains broadcast pending transactions in a public mempool before execution. Sophisticated actors deploy bots to scan this information and front-run large orders by manipulating transaction ordering.

Billions of dollars have been extracted through these practices in recent years. This directly conflicts with the fiduciary obligations of traditional brokers and institutional mandates requiring best execution. Financial institutions are unlikely to embrace a system that permits such extraction from client order flow.

Privacy, Compliance, and Control Requirements

Privacy and compliance requirements further strengthen the case against public ledgers. Traditional finance operates under strict Know Your Customer and Anti-Money Laundering regulations.

Public blockchains expose transaction data to everyone. Institutions cannot broadcast their strategic positioning or client holdings on a transparent ledger. Regulators also require the ability to freeze assets or reverse transactions under specific legal circumstances. Public blockchains generally resist these interventions, creating challenges when compliance frameworks require administrative control.

Private networks provide the logical solution. A private blockchain functions as a shared, cryptographically secure ledger maintained by a trusted group of regulated institutions.

This architecture delivers many of the benefits of distributed ledger technology without the unpredictability of public networks. Competitors cannot observe order flows, trade sizes, or account balances. Transactions remain confidential between authorized participants and regulators.

These networks can also streamline clearing and settlement by enabling institutions to transact directly with one another. This lowers costs, reduces counterparty risk, and supports continuous settlement. Enterprise networks further offer dedicated support and contractual service guarantees that public protocols do not provide.

Institutional Adoption Is Already Underway

Major financial institutions already recognize this reality. J.P. Morgan operates its Onyx platform for tokenized intraday repurchase agreement trades and payments. Goldman Sachs uses its Digital Asset Platform to issue and trade digital bonds and other institutional instruments.

HSBC's Orion platform supports tokenized gold and digital bond issuance. These examples demonstrate that financial institutions view blockchain primarily as infrastructure for automation, synchronization, and efficiency within controlled environments.

The Direction of Tokenized Equities

Market participants continue to pursue the vision of trading major corporate shares on public decentralized exchanges. Yet the structural, regulatory, and operational realities of global finance point elsewhere.

The Securities and Exchange Commission may eventually adapt market rules for digital assets, but the infrastructure itself will remain largely in private hands.

Tokenized equities are far more likely to thrive on secure, permissioned networks designed for institutional performance and compliance than on fully public chains. The future of financial innovation is not public exposure. It is private, efficient infrastructure built to meet the demands of modern capital markets.
