BlackRock files for buffer bitcoin ETF with capped upside and limited losses
BlackRock filed with the SEC for the iShares Bitcoin Managed Protection ETF, ticker PBIT, which seeks bitcoin exposure through options with capped gains and some downside protection rather than holding bitcoin directly, per Decrypt, CoinDesk and Bitcoin Magazine. Decrypt reported IBIT took in $665.2 million on the filing day, its only inflow among 12 funds.
5 independent publishers report it (copies of the same text count once); they may still rely on one underlying source. An official source would raise it.

Claims and open questions
What sources claim
- Per the SEC filing cited by Decrypt, each tranche's protection typically starts at about 90% of the reference asset's value, limiting initial losses to roughly 10% before fees.
- Decrypt reported, citing SoSoValue, that IBIT took in $665.2 million on Monday and held $66.37 billion in net assets, while Fidelity's FBTC lost $83.6 million and Grayscale's GBTC $54.9 million.
- Bitcoin Magazine reported that IBIT received $665.2 million in fresh investment on Monday, citing Farside Investors, and currently handles $65.7 billion.
Still unresolved
- What management fee BlackRock will set for PBIT, which Decrypt said was left blank in the filing.
- What level of downside protection and upside cap the fund will ultimately offer, which CoinDesk said the filing did not specify.
