BlackRock has reportedly submitted new paperwork to the U.S. Securities and Exchange Commission for a tokenized fund structure that will utilize blockchain-based ownership tracking through Securitize infrastructure. The filing, submitted on May 12, marks another major step in the asset management giant’s ongoing effort to integrate blockchain technology into traditional financial systems.
The proposed structure relies on Securitize Transfer Agent, LLC to maintain ownership records directly on-chain rather than through conventional financial recordkeeping systems. In traditional finance, transfer agents are responsible for verifying ownership rights, managing shareholder records, and ensuring compliance with investor eligibility standards. By shifting these functions onto blockchain rails, the firms are aiming to modernize asset administration and improve operational efficiency.
BlackRock’s latest SEC filing introduces a tokenized fund structure that records ownership directly on blockchain infrastructure through Securitize’s regulated transfer agent platform.
The partnership between BlackRock and Securitize is not new. BlackRock previously led a $47 million funding round for Securitize, strengthening the relationship between the two companies and positioning Securitize as a preferred blockchain infrastructure provider for the firm’s tokenization initiatives.
BUIDL Fund Demonstrates Institutional Tokenization Growth
The collaboration previously resulted in the launch of the BlackRock USD Institutional Digital Liquidity Fund, commonly known as BUIDL, in March 2024. The tokenized money market product quickly became one of the most significant blockchain-based financial offerings introduced by a major traditional finance institution.
Since its launch, the BUIDL fund has reportedly expanded to approximately $2.3 billion in assets under management, demonstrating increasing institutional interest in tokenized financial products. Industry analysts view the growth of BUIDL as evidence that blockchain-powered financial instruments can operate at substantial scale while remaining aligned with regulated financial frameworks.
The latest filing arrives during a period of rapid expansion within the tokenized real-world asset sector. Market estimates suggest that tokenized assets, including treasuries, private credit products, and real estate holdings, have now surpassed $30 billion in total market value.
Tokenization is increasingly attracting attention because it can potentially reduce settlement times from several days to near-instant execution. It may also simplify fractional ownership structures, automate compliance procedures through smart contracts, and enable markets to function continuously beyond standard business hours.
The success of BlackRock’s BUIDL fund, which has grown to roughly $2.3 billion in assets, is reinforcing confidence in institutional-scale tokenized finance products.
Regulatory Environment Continues to Evolve
For blockchain-focused companies and crypto-native investors, BlackRock’s continued expansion into tokenized finance is widely viewed as a strong signal that major financial institutions are moving beyond experimentation and actively adopting blockchain infrastructure for core financial operations.
Projects centered on real-world asset tokenization, regulatory-compliant blockchain systems, and institutional-grade infrastructure may benefit from rising demand as traditional finance firms continue exploring blockchain integration.
At the same time, regulatory clarity surrounding tokenized securities remains under development. Although the SEC’s willingness to process such filings is considered encouraging for the sector, the legal framework governing custody standards, investor protections, and securities compliance for tokenized funds is still evolving.
Industry observers are closely monitoring whether BlackRock expands tokenization beyond treasury-focused products into higher-yield and less liquid asset classes, which could significantly broaden blockchain adoption in traditional finance.
The latest filing may ultimately serve as another milestone in the growing convergence between traditional financial institutions and blockchain technology, particularly as large-scale asset managers continue testing the scalability and efficiency of tokenized investment structures.
