BlackRock Files Second Tokenized Fund with SEC
BlackRock filed with the SEC for a second tokenized fund, again selecting Securitize as its tokenization infrastructure partner. The move signals a deepening commitment to on-chain asset management and real-world asset tokenization.

Securitize's institutional footprint has expanded in parallel with BlackRock's filings. The New York Stock Exchange entered a memorandum of understanding with Securitize to explore support for tokenized securities, according to the NYSE's official announcement. Separately, Securitize launched a tokenized AAA CLO fund with services provided by BNY, bringing structured credit on-chain through a partnership with one of the largest custodians in the U.S. financial system, as detailed in BNY's corporate newsroom. These developments collectively establish Securitize as the dominant regulated tokenization infrastructure provider in the U.S. market, with BlackRock as its anchor client across multiple product categories.
The CoinDesk report on BlackRock's broader tokenization push noted that the firm has been expanding BUIDL's chain coverage as well, with Wormhole's documentation of BUIDL's extension to BNB Chain illustrating how the fund's interoperability footprint has grown since its initial deployment. The second SEC filing adds a distinct fund structure to this architecture rather than simply expanding BUIDL's chain presence, suggesting that BlackRock is building a portfolio of on-chain products with differentiated mandates rather than concentrating all tokenized exposure in a single vehicle.
The filing does not disclose the new fund's target asset class, proposed fee structure, minimum subscription threshold, or intended investor base. It does not identify whether the fund will hold Treasury securities, money market instruments, or another asset category. No launch date, target AUM, or distribution arrangement with broker-dealers has been made public. The SEC has not issued a comment letter or approval notice as of the date of this report, and the standard review period for registered fund filings means the product could remain in registration for several months before any investor access is established.
What the filing concretely establishes is that BlackRock has formally committed to a second tokenized fund structure under U.S. securities law, with Securitize named as the transfer agent of record and on-chain ledger operator. It does not establish the fund's investment mandate, confirm a launch timeline, disclose the terms of Securitize's compensation arrangement for this engagement, or indicate whether any institutional investor has pre-committed capital to the vehicle.
