In June, the crypto and US stock markets underwent a structural shift as exchanges including Binance, Bitget, MEXC, and Gate launched 24-hour spot trading for US stocks. While users executed transactions for Tesla stock tokens instantly, the underlying mechanics remained opaque. The infrastructure enabling this rapid product rollout and continuous trading outside traditional hours is provided by Alpaca, a Silicon Valley fintech unicorn. Data compiled by Woofun AI indicates that this entity, often termed the overseer of blockchain-based Wall Street, currently controls approximately 94% of the global market for tokenized US stocks and ETFs. Its services underpin nearly every major player in the sector, including Binance, Kraken, Ondo Finance, xStocks, and Dinari, despite the company remaining largely invisible to the public until its recent breakthrough.

Founded in 2015 by Yoshi Yokokawa, a former member of the securitization team at Lehman Brothers, Alpaca faced significant early hurdles. Co-founder and CTO Hitoshi Harada later admitted that founding the firm solely on entrepreneurial desire was a strategic error. The initial team attempted to build an AI product using deep learning but failed to address tangible business pain points, leading to four rejected applications to Y Combinator before finally gaining acceptance in the winter of 2019. This period of struggle highlighted the necessity of aligning technology with genuine market infrastructure gaps.

The company's trajectory shifted when the team identified a critical void in the financial ecosystem. While new entrants like Robinhood drove financial democratization and firms like Stripe and Plaid optimized payments and bank connectivity, no developer-friendly brokerage API infrastructure existed for securities trading and settlement. Without a robust technical foundation, developers were forced to independently secure brokerage licenses, build settlement systems, and manage custody banks, creating prohibitive barriers to entry for trading applications. Woofun AI notes that this realization prompted a difficult pivot from a machine learning focus to becoming a licensed self-clearing broker.

Transforming into a regulated entity subject to oversight by FINRA and SIPC required years of effort but yielded substantial competitive moats. By early 2025, prior to scaling tokenization operations, Alpaca had forged partnerships with over 300 institutions across more than 40 countries, supporting over 9 million brokerage accounts. Its client base spans financial institutions, fintech firms, and automated traders, facilitating access to US stocks, options, and cryptocurrencies with support for both whole-share and fractional-share transactions. As a self-clearing broker and DTCC member, Alpaca manages the entire trading settlement process independently, a distinct advantage over standard API providers.

This foundational work positioned Alpaca for explosive growth as industry trends evolved in 2024. Token Terminal data shows the total market value of tokenized stocks exceeded $1.2 billion by the end of 2025. In October of the previous year, Alpaca unveiled the Instant Tokenization Network (ITN) at the TOKEN2049 conference in Singapore. This innovation established a direct high-speed channel linking traditional Wall Street securities settlement systems with decentralized crypto blockchains. Woofun AI analysis suggests that years of securing licenses and building self-clearing systems were the primary drivers behind this rapid market capture.

As of January this year, Alpaca held approximately 94% of the market share in tokenized US stocks and ETFs, with dominance reaching 97% in the large and mega-cap tokenized stock segment. Major industry players like Ondo Finance, Dinari, and xStocks rely entirely on Alpaca for clearing and custody. In January, the company completed a $150 million Series D financing round, raising its valuation to $1.15 billion and cementing its unicorn status with total funding exceeding $320 million. The ITN platform functions as a clearing hub, custodian, and issuer partner, reducing settlement time lags to milliseconds and eliminating barriers to 24/7 liquidity.

The ITN architecture allows for immediate arbitrage and asset conversion across different blockchains. When a token's price deviates from its intrinsic value, traders can redeem the corresponding physical stock on one chain and mint equivalent tokens on another, stabilizing asset prices. This mechanism redefines the connection between traditional and crypto assets, enabling seamless value flow.

However, Alpaca's 94% market share presents a dual-edged sword; while it offers an unbeatable competitive advantage, it introduces systemic risk. Any technical failure, cyberattack, or regulatory shift could trigger a collective crisis for the billions of dollars in tokenized assets held by platforms like Binance and Bitget, making the entire ecosystem vulnerable to the performance of this single infrastructure provider.
