In recent years, the financial technology sector has introduced a novel way to hold equity interests: synthetic tokenized stocks. These digital representations of traditional shares are created on blockchain platforms and are marketed as a more efficient, borderless method for investors to gain exposure to publicly traded companies. However, despite the hype surrounding decentralised finance, many industry observers—including Aaron Kaplan, the founder of Promethum—warn that synthetic tokenized stocks pose serious risks to American investors and could destabilise the long‑standing, issuer‑centric capital markets model that underpins the United States’ financial system. At the heart of the issue is the concept of ownership.
In the conventional U.S. market, when an investor purchases a share of a corporation, that investor receives a legally recognised bundle of rights: voting power at shareholder meetings, entitlement to dividends, and a claim on the company’s residual assets in the event of liquidation. This framework is reinforced by a robust regulatory regime, clear custodial arrangements, and the backing of the Securities and Exchange Commission (SEC). Investors therefore have confidence that the share they hold is a genuine, enforceable stake in the underlying business.
Synthetic tokenized stocks, by contrast, are not actual shares. They are derivative contracts or digital tokens that aim to mirror the price movements of real equities. The token itself is typically issued by a third‑party platform that does not own the underlying shares, or that holds them in a pooled arrangement that may be opaque to token holders. As a result, the token holder’s claim is indirect and contingent upon the platform’s continued operation, its compliance with relevant laws, and its ability to maintain a sufficient reserve of the underlying securities.
This layered structure introduces several points of vulnerability. First, the trust that investors place in the U.S. market is diluted. When a token trades on a blockchain, the investor’s confidence shifts from the regulated exchange and the issuing company to the technology provider and the smart contract code.
Any flaw in the code, a hack, or a sudden regulatory crackdown can cause the token to lose value or become inaccessible, even if the underlying stock remains healthy. This disconnect undermines the fundamental principle that ownership of a share equals ownership of a piece of a company.
Second, synthetic tokens can short‑change American investors by exposing them to counterparty risk that is rarely present in traditional brokerage accounts. In a conventional setting, a broker’s custodial responsibilities are governed by strict capital‑adequacy rules, and the Securities Investor Protection Corporation (SIPC) provides a safety net up to a certain amount. Token platforms, however, often operate outside these protective frameworks.
If the platform fails, becomes insolvent, or is subject to legal action, token holders may find themselves without recourse, losing both their investment and any claim to the underlying shares. Third, the issuer‑led capital markets model—where companies raise capital directly from investors by issuing new shares—can be eroded by synthetic tokenization. When investors can acquire a token that mimics a stock without the company’s involvement, the company loses a potential source of fresh capital.
Moreover, the dilution of voting rights means that shareholders who hold tokens may not be able to influence corporate governance, weakening the accountability mechanisms that have historically kept management aligned with shareholder interests. Regulatory bodies are beginning to take notice. The SEC has issued guidance indicating that many tokenized securities fall under existing securities laws and must comply with registration, disclosure, and reporting requirements.
Yet enforcement remains uneven, and many platforms operate in jurisdictions with lax oversight. This regulatory ambiguity creates a “wild west” environment where investors may be lured by low fees and 24/7 trading but are left unprotected when the market turns volatile. Beyond the immediate risks, there are broader systemic concerns.
The proliferation of synthetic tokens could fragment liquidity across multiple blockchain networks, making price discovery less efficient. Traditional exchanges benefit from deep order books and stringent market‑making obligations that help stabilize prices.
Token markets, on the other hand, can experience sharp price swings due to thin trading volumes or manipulative practices that are harder to police. In addition, the tax treatment of tokenized stocks remains unclear.
While the IRS treats cryptocurrencies as property, it has not issued definitive guidance on how synthetic equity tokens should be reported. This uncertainty can lead to inadvertent tax liabilities for investors who are unaware of the nuances, further eroding the perceived benefits of tokenization. To safeguard the interests of American investors, several steps are advisable. First, regulators should clarify the legal status of synthetic tokens and enforce existing securities laws uniformly across platforms.
Second, platforms should adopt transparent custodial practices, perhaps by partnering with regulated custodians who can provide audited proof of the underlying share reserves. Third, investors should conduct thorough due diligence, assessing not only the token’s price performance but also the robustness of the underlying technology, the reputation of the issuing entity, and the legal safeguards in place. In conclusion, while synthetic tokenized stocks promise greater accessibility and innovative trading experiences, they also introduce a host of challenges that threaten the core principles of ownership, investor protection, and capital formation that have made U.S. markets a global benchmark.
By undermining the direct relationship between shareholders and the companies they invest in, these tokens risk shortchanging American investors and destabilising the issuer‑driven market structure. A careful, regulated approach—combined with heightened investor awareness—is essential to ensure that the benefits of blockchain technology do not come at the expense of the trust and stability that have long defined American equity markets.
