Secondary Market for Tokenized Equities: Building Institutional Liquidity
Secondary trading of tokenized equities operates through a handful of regulated venues — tZERO (SEC-registered ATS), Securitize Markets (FINRA broker-dealer marketplace), INX (SEC-registered exchange), and international platforms including ADDX (Singapore) and SDX (Switzerland). Combined daily trading volume across all venues remains below $100 million, a fraction of the $500+ billion daily volume on U.S. equity exchanges alone. The liquidity gap between tokenized and traditional equity markets is the single largest barrier to institutional adoption.
Current Trading Infrastructure
tZERO, majority-owned by Pelion Venture Partners (following Overstock’s reorganization), operates the longest-running SEC-registered Alternative Trading System for security tokens. tZERO lists a handful of tokenized equities including its own tZERO Preferred (TZROP) and third-party security tokens. Trading operates during U.S. market hours with T+0 settlement on tZERO’s proprietary blockchain. Despite the operational efficiency, trading volumes have remained modest — typically $1-5 million daily across all listed securities.
Securitize Markets provides compliant secondary trading for securities tokenized through Securitize’s platform. As both the transfer agent and the marketplace operator, Securitize offers an integrated primary-secondary model where issuers using Securitize for equity token offerings automatically gain access to secondary trading on Securitize Markets. This vertical integration parallels the model used by Broadridge DLR for tokenized repo.
INX’s SEC-registered securities exchange represents the most ambitious regulatory approach — a full exchange license rather than the lighter-touch ATS registration. INX can list and trade tokenized securities with the same regulatory status as NYSE or NASDAQ-listed securities, though the practical benefits of this status are limited by the current supply of listed tokenized equities.
Liquidity Challenges
Tokenized equity markets face a classic chicken-and-egg problem. Institutional investors won’t commit capital without adequate liquidity. Market makers won’t provide liquidity without sufficient investor demand. Issuers won’t tokenize equity without secondary market access for their shareholders. Breaking this cycle requires either a liquidity catalyst (a marquee listing that attracts attention) or structural changes (integration with existing equity trading infrastructure).
The structural approach is more promising. NASDAQ has developed digital assets capabilities and explored tokenized equity listing. London Stock Exchange Group (LSEG) announced a digital markets platform for tokenized securities. Deutsche Boerse’s Clearstream D7 platform could support tokenized equity settlement alongside tokenized fixed income. If any major exchange lists tokenized equities alongside traditional equities, the existing market-making infrastructure and investor base would provide immediate liquidity.
Private Market Secondary Trading
The most active segment of tokenized equity trading is private company shares — pre-IPO companies where traditional secondary markets (Forge Global, Nasdaq Private Market, EquityZen) already facilitate billions in annual trading volume. Tokenized private share trading through Securitize or tZERO could reduce settlement time from 30-60 days (typical for private secondary transactions) to T+0, while automating the compliance checks that currently require manual legal review.
For PE fund interests and venture capital fund stakes, tokenized secondary markets could provide the liquidity that limited partners increasingly demand. Hamilton Lane and KKR have tokenized fund interests through Securitize, enabling secondary trading of what were previously completely illiquid LP stakes.
Institutional Requirements
Institutional investors require best execution policies, pre-trade transparency, post-trade reporting, and integration with existing portfolio management and order management systems. The current tokenized equity venues lack connectivity to Bloomberg, Refinitiv, or the FIX protocol messaging that institutional equity desks use. SWIFT’s tokenized asset messaging work could provide the institutional connectivity layer.
Market surveillance, manipulation detection, and cross-market monitoring — requirements of all SEC-registered trading venues — must be implemented for tokenized equity markets. The blockchain’s transaction transparency actually simplifies some surveillance tasks (all trades are on-chain) but complicates others (pseudonymous addresses require identity resolution).
Market Making Economics
The viability of tokenized equity secondary markets depends fundamentally on market-making economics — whether designated market makers can profitably provide continuous liquidity at competitive bid-ask spreads. Traditional equity market makers (Citadel Securities, Jane Street, Virtu Financial) generate revenue from the bid-ask spread while managing inventory risk through hedging and repo financing. For tokenized equity venues to attract these market makers, several conditions must be met.
First, inventory financing through tokenized repo must be available for tokenized equity collateral. Broadridge DLR currently supports Treasury and agency MBS collateral; extending to tokenized equity collateral would enable market makers to finance their inventories at competitive rates. Without repo financing, market makers must fund inventory positions from their own capital at much higher effective costs, resulting in wider bid-ask spreads that deter institutional participation.
Second, cross-venue connectivity through SWIFT messaging and Canton Network interoperability must enable market makers to aggregate liquidity across multiple tokenized venues. A market maker quoting on tZERO, Securitize Markets, and INX simultaneously needs real-time position management across venues — the same cross-venue capability that traditional equity market makers use through FIX protocol connectivity to multiple exchanges.
Third, risk management infrastructure must accommodate tokenized equity positions alongside traditional positions. Market makers hedging tokenized equity exposure with traditional equity derivatives need portfolio margining that recognizes cross-asset offsets. DTCC’s integration with tokenized asset infrastructure could provide this cross-margining capability.
Automated Market Makers (AMMs) vs Order Books
A distinctive feature of tokenized equity secondary markets is the availability of automated market maker (AMM) mechanisms alongside traditional order book matching. AMMs — popularized by Uniswap and other DeFi protocols — provide continuous liquidity through algorithmic pricing based on a bonding curve formula. While AMMs have limitations for institutional trading (impermanent loss, front-running vulnerability, limited price discovery for illiquid assets), they provide baseline liquidity that prevents zero-volume trading days.
Several tokenized equity venues have implemented hybrid models: AMM-provided liquidity as a floor, supplemented by institutional limit orders from designated market makers. This hybrid approach ensures that investors can always execute trades (through the AMM) while benefiting from tighter spreads when institutional market makers are active. The hybrid model is particularly relevant for private share secondary markets where trading is episodic rather than continuous.
Regulatory Surveillance and Compliance
SEC-registered trading venues for tokenized equities must implement market surveillance, manipulation detection, and best execution monitoring at standards comparable to traditional exchanges. The blockchain’s transaction transparency simplifies some surveillance functions — all trades are recorded immutably with timestamps and participant addresses — but creates new challenges.
Pseudonymous blockchain addresses require identity resolution: the surveillance system must map on-chain addresses to verified identities to detect wash trading, insider trading, and market manipulation by connected parties. Cap table tokenization platforms that maintain KYC-verified address registries provide the identity layer that surveillance systems need.
Cross-market surveillance — monitoring for manipulation that spans tokenized and traditional equity markets — requires integration between blockchain-based surveillance and traditional market surveillance systems. If the same company has traditional shares trading on NASDAQ and tokenized shares trading on tZERO, surveillance must detect cross-market manipulation strategies that exploit the settlement timing difference (T+1 vs T+0) or the regulatory reporting asymmetry between venues.
International Secondary Markets
International secondary market venues complement the U.S.-focused platforms. ADDX (Singapore, MAS-licensed) provides institutional secondary trading for tokenized securities across Asia-Pacific. SDX (Switzerland, FINMA-licensed) operates an exchange-grade platform for tokenized securities in Europe. Archax (UK, FCA-regulated) offers institutional tokenized security trading within the UK regulatory framework.
These international venues serve institutional investors in their respective jurisdictions while connecting to the broader tokenized equity ecosystem through Canton Network interoperability and SWIFT messaging. The multi-venue, multi-jurisdiction structure mirrors traditional equity market fragmentation — where the same company may trade on NYSE, London, and Tokyo — but with the potential for atomic cross-venue settlement that traditional equity markets cannot achieve.
Goldman Sachs and HSBC participation in international secondary markets provides the institutional credibility and market-making capability that these venues need to attract institutional order flow. The regulatory landscape is converging across major jurisdictions, reducing the compliance friction that currently limits cross-border tokenized equity trading.
Settlement and Custody Infrastructure
The settlement infrastructure for tokenized equity secondary trading builds on the same components as fixed-income tokenization: BNY Mellon digital custody for safekeeping, DTCC integration for clearing and settlement, and Canton Network for interoperability between venues, custodians, and settlement systems.
For institutional investors, the key requirement is custody integration: the ability to hold tokenized equity in the same custodial account and portfolio management system as traditional equity. BNY Mellon’s unified traditional and digital custody platform addresses this requirement, enabling institutional investors to view tokenized equity positions alongside traditional holdings in a single reporting framework.
Outlook
Tokenized equity secondary markets will likely develop first in private markets (where the status quo is most inefficient) and expand to public markets (where existing infrastructure is competitive). The Canton Network’s interoperability between trading venues and digital custodians would enable institutional equity desks to trade tokenized equities through familiar workflows. The regulatory pathway is clear — existing ATS and exchange frameworks accommodate tokenized securities — but the commercial case depends on achieving sufficient liquidity to attract institutional capital.
The equity market forecast projects that tokenized equity secondary market daily volume could reach $500 million-$1 billion by 2030, driven primarily by private market secondary trading and supported by traditional exchange integration. This growth trajectory — from less than $100 million daily to $500+ million — represents the liquidity formation that institutional investors require before committing significant capital to tokenized equity allocations. The comparison between tokenized and traditional equity issuance demonstrates that the economic advantages are clear; the remaining challenge is building the institutional-grade secondary market infrastructure to realize those advantages at scale.
According to DTCC research, secondary market liquidity formation is the most critical factor for tokenized equity adoption, and the convergence of exchange tokenization, institutional market-making, and custody integration represents the path to achieving the liquidity threshold that triggers broader institutional participation.
Dark Pool and Block Trading for Tokenized Equity
Institutional equity trading occurs predominantly through dark pools and block trading venues — platforms that enable large trades without revealing order information to the broader market. For tokenized equity, institutional-grade dark pool functionality requires: pre-trade anonymity (counterparties cannot identify each other before execution), minimum order sizes (preventing retail order flow from fragmenting institutional liquidity), and integration with institutional order management systems (Bloomberg TOMS, Charles River).
The Canton Network architecture — where each participant sees only the data they are authorized to access — provides a natural foundation for institutional dark pool functionality. Goldman Sachs and JPMorgan, both operators of traditional equity dark pools (Sigma X and JPM-X respectively), could extend their dark pool technology to tokenized equity trading on their respective blockchain platforms.
For private share secondary trading, block trading functionality is particularly important. Large transactions in pre-IPO company equity — $10-50 million blocks from venture fund distributions — require controlled execution to prevent price impact. Tokenized block trading platforms could provide the combination of price discovery (RFQ to qualified buyers), execution (atomic settlement through smart contracts), and post-trade processing (SWIFT reporting, custody transfer) that institutional block traders require.
The regulatory compliance framework for tokenized dark pools follows the same ATS registration requirements as traditional dark pools — SEC Regulation ATS applies to any platform that brings together buyers and sellers of securities, regardless of the settlement mechanism. The tokenized format provides enhanced post-trade transparency (every trade recorded on-chain with immutable audit trail) while maintaining pre-trade anonymity through privacy-preserving transaction protocols.
Price Discovery Mechanisms for Illiquid Tokens
The fundamental challenge for tokenized equity secondary markets is establishing reliable price discovery for securities that trade infrequently. Traditional equity markets derive prices from continuous order flow — thousands of transactions per second for liquid stocks. Tokenized equity venues may see a handful of trades per day for a given security, creating price gaps that make institutional participation difficult.
Request-for-quote (RFQ) systems — where a buyer or seller solicits competing quotes from multiple market makers before executing — provide a solution adapted from institutional fixed-income and FX markets. For tokenized equity, RFQ protocols enable institutional block trades without revealing order information to the broader market. The Canton Network architecture supports RFQ workflows where counterparty identity is revealed only after trade execution, maintaining pre-trade anonymity while enabling competitive pricing.
Periodic auction mechanisms — where orders accumulate over a defined window (hourly, daily) and execute at a single clearing price — provide an alternative that concentrates liquidity at predictable times. SDX in Switzerland operates periodic auctions for tokenized securities, providing reliable execution windows that institutional investors can plan around. The combination of continuous AMM liquidity, RFQ for block trades, and periodic auctions for price discovery creates a multi-layered market microstructure suited to the current low-volume phase of tokenized equity markets.
The total RWA tokenization market at $20 billion in TVL (excluding stablecoins) with 630,000+ holders provides the base from which tokenized equity secondary volumes will grow. As Broadridge extends DLR capabilities beyond repo to include equity financing, and as DTCC integrates tokenized equity settlement with its $2.4 quadrillion annual settlement infrastructure, the secondary market infrastructure gap between tokenized and traditional equities will narrow. The tokenized bond secondary market development trajectory — from fragmented pilot venues to integrated institutional infrastructure — provides the template that tokenized equity markets are expected to follow.
