Blackrock, the world's largest asset manager, filed an updated prospectus for its iShares Bitcoin Trust (IBIT) with the U.S. Securities and Exchange Commission (SEC) this week, officially adding several Wall Street heavyweights as authorized participants. The filing shows IBIT now has nine authorized participants: ABN AMRO Clearing USA, Citadel Securities, Citigroup Global Markets, Goldman Sachs, Jane Street Capital, JP Morgan Securities, Macquarie Capital (USA), UBS Securities, and Virtu Americas. These institutions are responsible for creating and redeeming IBIT shares, with each basket representing 40,000 shares.
Growing Roster of Authorized Participants
Initially, only Jane Street Capital, JP Morgan Securities, Macquarie Capital (USA), and Virtu Americas were named in IBIT's January 9 prospectus. A March 4 amendment added ABN AMRO Clearing USA, Citigroup Global Markets, Goldman Sachs, and UBS Securities. The latest amendment brings in Citadel Securities, expanding the total to nine. Blackrock's rapid expansion of its authorized participant network signals a major upgrade in liquidity infrastructure to accommodate surging market demand.
IBIT Holdings Near 260,000 BTC
Since IBIT launched on January 11, Blackrock has been aggressively accumulating bitcoin. As of Thursday, April 4, the iShares Bitcoin Trust's bitcoin holdings approached 260,000 BTC, valued at approximately $18 billion. This makes IBIT one of the fastest-growing ETFs in history. Blackrock CEO Larry Fink said last week that he is "very bullish on the long-term viability of Bitcoin," noting that IBIT "is the fastest growing ETF in the history of ETFs" and "nothing has gained assets as fast as IBIT in the history of ETFs." Robert Mitchnick, Blackrock's head of digital assets, emphasized that for the firm's clients, "bitcoin is overwhelmingly the number one priority," followed by a small amount of Ethereum and very little else.
Strong Signal of Institutional Adoption
The addition of top-tier market makers like Goldman Sachs, Citigroup, and Citadel Securities is widely interpreted as a clear signal that traditional finance giants are accelerating their embrace of crypto assets. These institutions will not only enhance IBIT's liquidity and pricing efficiency but likely attract more institutional capital through their own distribution networks. As of now, IBIT's assets under management exceed the combined total of all other spot bitcoin ETFs, further cementing Blackrock's leadership in the digital asset ETF space.
