The financial sector initially envisioned tokenization as a mechanism for seamless, 24/7 asset transactions globally.

However, the current trajectory of stock tokenization indicates a deviation toward market fragmentation rather than unification. On May 19, Bloomberg reported that the SEC is drafting new exemption regulations and pilot rules to authorize on-chain stock tokenization transactions, with an official announcement anticipated within the week. While the SEC's potential approval of on-chain stock trading signals a major expansion for the crypto market, significant industry opposition persists. This contradiction stems from the specific regulatory framework being proposed, which centers on the third-party tokenization model.

The core of these new regulatory measures involves opening compliance pathways for third-party-led tokenization. In January 2026, the SEC issued the "Position Statement on Tokenized Securities," categorizing tokenized securities into four distinct types. Beyond the issuer-led model, the custodial, revenue-linked, and security-linked derivative models are classified as third-party-led, meaning external institutions manage the tokenization process rather than the stock issuers themselves. Historically, the SEC has maintained a cautious stance, deeming only issuer-led and custodial models compliant. Issuer-led tokens align with existing securities laws by merely changing asset representation, a model approved in January. Custodial tokens received a no-action letter in December 2025, permitting limited operation. Conversely, revenue-linked and security-linked derivative models lack full shareholder rights and require separate oversight, currently barring platforms like Ondo Finance and xStocks from serving U.S. users.

Recent market rumors suggest the SEC intends to pivot, introducing innovative exemption clauses to officially sanction third-party tokenization. Maintaining the status quo would have been the safest regulatory path, as issuer-led and custodial models align closely with traditional securities frameworks. The sudden relaxation of restrictions appears driven by a desire to diversify capital market innovation and provide compliant pathways for crypto platforms outside traditional exchanges. Data compiled by Woofun AI indicates that persistent lobbying by Coinbase played a pivotal role in this policy shift. Coinbase has long sought entry into stock tokenization, especially as competitor Robinhood established multi-product services for stocks, cryptocurrencies, and tokenized equities. Since late last year, Coinbase has aggressively pursued a comprehensive trading platform strategy focused on stock tokenization.

Current regulations present a structural barrier for Coinbase. To operate compliantly, the exchange would need to rely on SEC-registered transfer agents, a qualification it lacks. Adopting Robinhood's model of issuing value-linked tokens via a subsidiary would violate regulatory requirements for U.S. users. Consequently, lobbying the SEC to create a compliant pathway for third-party synthetic token securities became Coinbase's primary strategy. In January 2026, Coinbase founder Brian Armstrong publicly opposed the draft CLARITY Act, arguing it would effectively ban stock tokenization. His objection targeted Article 505(e)(2), which mandates that tokenized assets remain subject to traditional financial regulatory rules. While this provision does not ban tokenization entirely, it restricts the unauthorized third-party model Coinbase seeks to implement, as compliant platforms like Securitize and Superstate already operate under these constraints.

In March 2026, Coinbase submitted a formal opinion letter to the SEC titled "Third-Party Tokenization of Publicly Traded Securities Does Not Require Permission from the Issuing Company." The letter argued that third-party institutions should be able to tokenize and circulate publicly traded stocks without prior issuer authorization, overturning the requirement for explicit consent from listed companies or transfer agents. Woofun AI notes that while the arguments presented were reasonable on the surface, the underlying objective was to secure a regulatory framework allowing Coinbase to launch stock tokenization services without issuer approval. Although the SEC's decision to allow third-party tokenization appears beneficial for industry growth, two critical realities complicate the narrative. The field is highly competitive, and different platforms operate under vastly different qualifications. Citron Research stated that Coinbase's intense lobbying was essentially an attempt to curb the development of legitimate, compliant platforms like Securitize.

A more profound concern is the risk of liquidity fragmentation. If all third-party models are permitted, a single company's stock could exist as multiple, incompatible token products across various platforms. For instance, Tesla stock is already traded on NASDAQ and alternative trading systems. Third-party tokenization could further fragment these assets not just by channel but by form. Issuer-led and custodial tokens preserve the essence of physical stocks, allowing seamless interaction.

However, revenue-linked and security-linked derivative tokens are fundamentally different; they are derivative contracts tied to stock prices but separated from physical stocks in regulatory classification and shareholder rights. Currently, Tesla stock has spawned distinct tokens such as Ondo Finance's TSLAon, xStocks' xTSLA, and Robinhood's Tesla stock tokens. Despite sharing the same underlying asset, their regulatory rules and equity structures differ, rendering them incompatible and causing liquidity fragmentation.

When stock fragmentation extends beyond trading channels to affect asset forms, it creates investor confusion and undermines the original purpose of tokenization: facilitating free, convenient cross-border transactions. Woofun AI analysis suggests that achieving the initial vision of seamless global asset transactions requires a decisive strategic path. The industry must either adhere to strict regulatory compliance, permitting only issuer-led and custodial models that preserve shareholder rights, or fully embrace all third-party models while establishing robust legal and industry-wide regulations to address liquidity fragmentation. Without such measures, the proliferation of incompatible synthetic securities risks creating a fractured market landscape.
