With the recent advent of spot Bitcoin ETFs in the United States, the BlackRock Bitcoin ETF has come into the spotlight as one of the most talked-about investment instruments in the Bitcoin ecosystem.
The fund has opened up a new avenue for the investors who can now own Bitcoin through their standard brokerage accounts. It marks an important step in Bitcoin’s history since it allows the users to have access to Bitcoin without owning the actual crypto coin.
As of June 2026, IBIT had some 774,434.1 BTC which accounted for around 3.8% of the circulating supply of Bitcoin making it the biggest Bitcoin ETF in terms of holdings.

The CME CF Bitcoin Reference Rate is used to determine the purchase price. The mechanics behind the BlackRock Bitcoin Exchange-Traded Fund.
BlackRock Bitcoin ETF functionality
The exchange-traded fund uses a creation and redemption model that is aimed at keeping the fund’s share price close to the fair value of the asset.
In case there are enough people who need the shares of the ETF, then new shares will be created, and they will be used to buy more coins.
However, if someone decides to liquidate their shares, then the fund itself may sell its shares to cover its redemption obligation.
The fund values daily based on the CME CF Bitcoin Reference Rate. The benchmark is a collection of prices from several cryptocurrency exchanges, and is used to set a reference price for Bitcoin.
The annual management fee for the fund is 0.25% of the fund’s value, including the management and administration costs of the fund.
The organization and safeguarding of property.
Coinbase Custody Trust Company, also known as Coinbase Prime, custodies the Bitcoin on IBIT. The assets are stored in ‘cold storage’ (offline), and are not connected to Internet-based systems.
According to the structure of the fund:
- All Bitcoins are held in different wallets.
- The Company does not have any funds invested in the corporation’s Coinbase investments.
- Transfers require multi-signatures
- Regularly, security reviews and audits are carried out.
This allows investors to not directly manage their private keys or digital wallets. Instead, the custodian will be responsible for custody of the ETF.
