BlackRock’s iShares Trust filed with the US Securities and Exchange Commission on October 19 for the iShares Bitcoin Managed Protection ETF, a proposed fund expected to trade under the ticker PBIT. The filing says PBIT would seek upside exposure to BlackRock’s iShares Bitcoin Trust ETF (IBIT), or similar bitcoin exposure, while providing a level of downside protection.
The proposal would give investors a different route to bitcoin-linked exposure than simply holding IBIT. Rather than offering uncapped participation in the referenced exposure, the fund would use an options-based strategy that places limits on both potential gains and the protection available.
PBIT filing ties protected exposure to IBIT
BlackRock’s proposed PBIT ETF would seek exposure to IBIT or comparable bitcoin exposure through its Bitcoin Managed Protection Strategy, according to the SEC filing . The prospectus frames it as a managed-protection product, not a direct promise to shield holders from all bitcoin-related losses.
PBIT is only the expected ticker at this stage: the filing is procedural, the ETF is not established as available for trading, and no launch date is provided.
Overlapping option tranches
BlackRock’s proposed strategy is built around overlapping tranches. Options would set caps and protection-start values for each tranche.
The filing presents PBIT as distinct from a straightforward allocation to IBIT: it seeks to retain some upside exposure to bitcoin while exchanging part of that potential return for defined protection features.
Those features are not a blanket hedge. A protection-start value does not guarantee protection against a falling market; the level and timing depend on the relevant option positions and tranches, and BlackRock warns that investors may lose some or all of their investment.
Loss risk remains
The Block reported that BlackRock’s IBIT held more than $65 billion in assets on October 19 and was the largest bitcoin ETF of its kind.
PBIT would be tied to the iShares Bitcoin Trust ETF and would package exposure to the underlying bitcoin market for investors willing to accept capped gains in return for a stated level of downside protection.
The filing describes a capped, option-based structure alongside that protection. It also explicitly warns that investors may lose some or all of their investment, so the protection language should not be read as an assurance that PBIT holders cannot suffer losses.
