BlackRock’s iShares Bitcoin Trust ETF ($IBIT) gives investors exposure to Bitcoin ($BTC) without requiring them to manage private keys. That raises a common question: who actually owns the Bitcoin held in the fund? The answer is spread across several parties, and BlackRock is not the personal owner of the coins.
According to the fund's prospectus, the iShares Bitcoin Trust ETF is a Delaware statutory trust that issues shares representing fractional undivided beneficial interests in its net assets. Those assets consist primarily of Bitcoin held by a custodian on the trust's behalf. In an SEC filing, the trust says its purpose is to own bitcoin transferred to or purchased by it in exchange for shares.
In practice, investors buy shares linked to the trust's Bitcoin rather than buying coins directly. Their economic interest is represented by those shares, so the value of $IBIT generally tracks the price of Bitcoin, after fees and other liabilities. Holders include individuals, financial institutions and other market participants.
BlackRock's role is that of sponsor. Per SEC filings, the sponsor is iShares Delaware Trust Sponsor LLC, an indirect subsidiary of BlackRock, while BlackRock Fund Advisors serves as trustee. Wilmington Trust acts as Delaware trustee. Managing and overseeing the trust under its governing documents is not the same as owning its assets for corporate benefit, and the trust's Bitcoin is not a BlackRock treasury holding.
Coinbase Custody Trust Company serves as the trust's Bitcoin custodian and safeguards the private keys. The prospectus also names Anchorage Digital Bank as an available alternative custodian, and the sponsor decides how much is held at each. Custody does not make Coinbase the beneficial owner. The coins are held on behalf of the trust.
The trade-off for investors is control. Buying $IBIT shares provides exposure through a regulated securities market, but it is not the same as holding $BTC in a personal wallet. Shareholders cannot use their shares to send Bitcoin to another wallet or control the fund's private keys.
Creation and redemption rights are also limited. The SEC issued orders on July 29, 2025, and the trust is now authorized to create and redeem shares with authorized participants on an in-kind basis. These participants are large institutional firms. A later prospectus for a separate Bitcoin product states that shareholders who are not authorized participants have no right to redeem their shares and must generally sell in the secondary market. The same limit applies to ordinary $IBIT holders, who cannot redeem directly for Bitcoin.
So, who owns BlackRock's Bitcoin? The trust holds it, shareholders have beneficial interests in the trust's assets, BlackRock oversees the fund, and Coinbase provides custody.
