Alpaca collapses five-to-eight-week private share settlement into days, per company disclosures. That compression, delivered through self-clearing architecture, explains why the firm reportedly commands approximately 94% market share in assets under custody related to tokenized US stocks and ETFs. It also exposes the structural choice that now divides institutional tokenization: banks are layering digital rails onto legacy clearing infrastructure, while crypto-native platforms are rebuilding clearing itself.
Three production deployments in June 2026 illustrate the fork. Citi launched Digital Depositary Receipts that route tokenized private shares through SIX's regulated Swiss central securities depository, with Citi serving as custodian responsible for settlement and safekeeping. Deutsche Bank is building DAMA 2 as an Ethereum Layer-2 on zkSync to bring tokenized assets on-chain with regulatory-grade privacy for institutional clients. Binance opened 7,000-plus US stocks and ETFs to non-US users through its ADGM broker-dealer entity and Alpaca, with cumulative turnover reportedly passing $1 billion in nine days and accumulating roughly $400 million in total value locked. Three systems, three fundamentally different answers to who controls the clearing layer.
The architectural divergence matters because clearing is where settlement risk concentrates and where intermediaries extract rent. Traditional securities settlement in the US flows through the DTCC, which interposes itself between buyer and seller, guarantees the trade, and collects fees for the service. Most broker-dealers outsource clearing to a handful of dominant firms—Apex, Pershing, Fidelity Clearing—which means every transaction depends on a third-party clearinghouse maintaining its books and capital reserves. That dependency introduces counterparty risk, settlement delay, and cost. Self-clearing brokerages eliminate the middleman by maintaining their own books and clearing their own trades, but the model requires regulatory approval, capital reserves, and operational complexity that only a few firms can sustain.
Alpaca is one of those firms. Founded in 2015 by Japanese entrepreneurs Yoshi Yokokawa and Hitoshi Harada, the company transitioned from algorithmic trading software to a FINRA-registered, SIPC-member self-clearing brokerage headquartered in San Mateo. Its Brokerage API encapsulates compliance, risk control, and settlement logic into REST and WebSocket interfaces, earning it the label "Stripe of securities trading." The self-clearing capability—integrated execution, clearing, and custody—became the foundation for tokenized equity infrastructure. When a platform like Binance wants to offer real shares or tokenized wrappers backed by real shares, Alpaca handles order execution, maintains the customer books, clears the trades, and holds the underlying securities in custody. No external clearinghouse sits in the middle.
That vertical integration collapses settlement time and eliminates a layer of counterparty risk.
The speed difference is stark in private markets. Traditional secondary trading of private shares involves PDF documents, paper records, and manual processes that stretch settlement from five to eight weeks. Alpaca's infrastructure compresses that timeline to days. The company reportedly raised $150 million in Series D funding in January 2026 led by Drive Capital at a $1.15 billion valuation, with backers including Citadel Securities, Kraken, BNP Paribas, MUFG, and DRW. By December 2025, Alpaca reportedly claimed approximately 94% market share in assets under custody related to tokenized US stocks and ETFs, per data disclosed by the company. That dominance reflects not just technology but structural advantage: self-clearing means Alpaca doesn't rely on a third party to guarantee settlement, so it can move faster and cheaper than competitors who do.
Binance's real-share product demonstrates the operational consequences. Launched June 1, 2026, the service offers over 7,000 US stocks and ETFs to eligible non-US users with a $5 minimum, 24/5 trading, and zero commission. Orders route through Nest Trading Limited, an ADGM-licensed brokerage, while Alpaca handles execution, clearing, custody, dividend distribution, and corporate actions. Within nine days, the platform turned over roughly $143 million per day on average, versus the tokenized spot market's roughly $35 to $40 million on peak weekdays. Daily active traders peaked at 30,700, and total value locked reached approximately $400 million. The coverage advantage is structural: Binance lists 7,000-plus names against the tokenized wrapper market's roughly 200, and liquidity followed breadth.
On June 10, Binance launched bStocks, a tokenized layer on BNB Chain backed by real shares through a regulated SPV, letting holders use the underlying in DeFi while still earning dividends. Two products, two jobs: the real-share service owns access, while bStocks adds composability.
The most-traded names reveal demand segmentation. On Binance's real shares, six of the top ten are semiconductors, the top five account for 43% of volume, and Marvell alone represents roughly 15%. The tokenized wrapper market leans crypto-linked: Coinbase, Robinhood, and MicroStrategy rank far higher there than on Binance. Across TradFi-category perpetuals—synthetic exposure to commodities, equities, indexes, and pre-IPO names—equities climbed from approximately 10% of volume at the start of May to roughly 40% by month-end on rising absolute flow. Spot tokens, perpetuals, and real shares are three expressions of the same demand, and the contest is over who serves it best.
Banks chose a different path. Citi's Digital Depositary Receipts apply the bank's traditional depositary receipt product to private market shares using blockchain infrastructure operated by SIX, one of the world's first fully regulated digital central securities depositories. Citi acts as both issuer and custodian on the platform, responsible for settlement and safekeeping. The tokenized instruments represent economic exposure and contractual claims rather than direct equity ownership; the underlying shares remain unchanged, but rights are represented through a depositary receipt wrapper. This lets companies maintain control over voting and cap table management. The inaugural transaction involved Kaleido, an institutional tokenization platform and Citi portfolio company, and investors within Citi's wealth management division.
The real moat isn't tokenization; it's who controls the moment when the trade becomes final.
The structure preserves banking control: Citi interposes itself as custodian, SIX operates the regulated CSD, and settlement flows through established financial intermediaries. As Biswarup Chatterjee, head of partnerships and innovation for Citi Services, explained, the product is "designed to provide superior client service, safeguard assets and facilitate capital markets activity with the same rigor that underpins traditional financial markets."
Deutsche Bank's DAMA 2 takes a different technical approach but retains the same custody philosophy. Built as an Ethereum Layer-2 on zkSync, per openpr.com in June 2026, the platform brings tokenized assets on-chain with regulatory-grade privacy for institutional clients.
The contrast with Alpaca is architectural. Citi and Deutsche built tokenization layers atop legacy custody and clearing frameworks. Citi routes through SIX's CSD and serves as custodian; Deutsche wraps Ethereum in a privacy layer. Both preserve the bank's role as settlement guarantor and intermediary. Alpaca rebuilt clearing itself: the firm holds the licenses, maintains the books, and settles trades internally without routing through a third-party clearinghouse. That difference determines speed, cost, and who captures the economic rent. Self-clearing compresses settlement from weeks to days because no external party needs to reconcile, guarantee, or clear the transaction. Custody-first models preserve institutional trust and regulatory familiarity but inherit the settlement timelines and fee structures of the systems they layer over.
The competitive question is not which blockchain wins but whether traditional banks will retain settlement control or cede it to vertically integrated platforms that own the full stack from custody through finality. Alpaca's 94% market share in tokenized US stock custody suggests the answer is tilting toward self-clearing infrastructure. Banks are building tokenization, but crypto-native firms are rebuilding the clearing layer itself—and in capital markets, the clearing layer is where settlement happens, risk concentrates, and margins accumulate. The real moat isn't tokenization; it's who controls the moment when the trade becomes final.
