Fight over tokenized stocks heats up

Fight over tokenized stocks heats up A fresh fight at the United States Securities and Exchange Commission is turning tokenized stocks into a test of who gets to control the next layer of market infrastructure. On April 6, 2026, the Blockchain Association filed a rebuttal to Citadel Securities, arguing that Citadel is trying to stretch securities rules over blockchain software in a way that would protect today’s gatekeepers more than investors. (sec.gov) At the center of the dispute is a simple idea with big consequences. A tokenized stock is a blockchain-based digital representation tied to an equity security, and supporters say that format could make trading, ownership records, and settlement move more like internet software than like the patchwork of brokers, exchanges, clearing firms, and custodians that dominate markets now. (sec.gov) Citadel is not arguing that tokenization itself should be banned. In its December 2, 2025 letter to the Securities and Exchange Commission, the firm said tokenization could improve clearing and settlement efficiency, shareholder engagement, and investor choice, but insisted that tokenized securities should still be subject to the same core protections that govern ordinary stock trading. (sec.gov) That sounds narrow until the argument reaches decentralized finance. Citadel told the Securities and Exchange Commission that the agency should identify the intermediaries involved in tokenized stock trading, including so-called decentralized trading protocols, and should avoid broad exemptions from the legal definitions of “exchange” and “broker-dealer.” (sec.gov) That framing matters because the legal labels decide who must register, supervise activity, keep records, and bear liability. If a blockchain protocol, front-end interface, validator, or software developer is treated like a traditional market intermediary, the compliance burden could be so heavy that only large incumbent firms would be able to operate at scale. (sec.gov) The Blockchain Association is pushing back on exactly that point. Its April 6 submission says non-custodial technology participants such as protocol developers, validators, front-end interfaces, and liquidity providers do not fit the statutory definitions of “exchange,” “broker,” or “dealer” when they do not exercise discretion, hold customer assets, or intermediate transactions. (sec.gov) In plain terms, the trade group is asking the Securities and Exchange Commission to separate the rails from the operators. Its letter says federal securities law regulates people and firms that actually perform intermediary functions, while neutral software and autonomous smart contracts should not automatically be treated as if they were brokers standing between buyer and seller. (sec.gov) The association is also telling the agency that it does not need Congress to act before testing a narrower framework. According to the filing, the Securities and Exchange Commission already has authority under Section 36 to grant targeted exemptive relief, and it points to the agency’s history of using conditional exemptions and no-action style approaches as markets evolved. (sec.gov) That makes this less a fight about code than a fight about market structure. If regulators decide tokenized stocks must travel through the same kinds of registered intermediaries that run today’s system, blockchain may end up serving mainly as a back-office upgrade for Wall Street incumbents rather than as a new competitive venue. (sec.gov) The timing is not accidental. The Securities and Exchange Commission has spent the past year publicly digging into tokenization through its Crypto Task Force, including a May 12, 2025 roundtable on “Tokenization: Moving Assets Onchain: Where TradFi and DeFi Meet,” with Commissioner Hester Peirce describing tokenization as a development that could substantially change financial markets. (sec.gov) The issue has also moved onto Capitol Hill. On March 25, 2026, the House Financial Services Committee held a hearing titled “Tokenization and the Future of Securities: Modernizing Our Capital Markets,” and Blockchain Association chief executive officer Summer Mersinger appeared alongside representatives from the Depository Trust and Clearing Corporation, Nasdaq, the Securities Industry and Financial Markets Association, and Plume. (financialservices.house.gov) That witness list showed how unusual this moment is. The same conversation now includes crypto advocates who want open blockchain rails, legacy market utilities that run core post-trade plumbing, exchange operators that could list tokenized products, and trade groups representing the firms that dominate traditional securities markets. (financialservices.house.gov) Citadel’s position reflects a broader concern inside traditional finance that tokenized equity markets should not be allowed to sidestep rules on best execution, fair access, and market transparency. The firm’s submission says tokenized U.S. equities should be treated the same way as traditional equity securities from a regulatory perspective, especially when the token transfer effectively moves the underlying stock. (sec.gov) The Blockchain Association’s position reflects the opposite fear. Its filing says Citadel’s approach would “improperly extend regulation to neutral technology providers,” and it argues that forcing blockchain infrastructure into old intermediary categories would freeze the architecture of markets around the firms that already own the pipes. (sec.gov) That is why this policy fight matters beyond crypto. The question before regulators is whether tokenization becomes a new wrapper around the old system, or whether it opens enough room for new trading, settlement, and ownership models to challenge the firms that have long controlled how stocks move.
