Summary
BlackRock has filed with the U.S. Securities and Exchange Commission for the iShares Bitcoin Managed Protection ETF, ticker PBIT, which would list on the Nasdaq stock exchange. The product aims to pair upside exposure to bitcoin with what the filing calls "downside protection." Rather than buying bitcoin directly, PBIT would use options linked to the iShares Bitcoin Trust ETF (IBIT) and hold fixed-income investments to generate interest income. According to James Seyffart, the filing marks BlackRock's third bitcoin ETF filing, and he noted that the industry still has only bitcoin and ethereum products.
The prospectus describes a "protection start value" in which purchased options carry an exercise price approximately 10% below the starting value of the reference asset, establishing an initial loss exposure of roughly 10% before fees and other expenses. The fund would buy and sell call options on IBIT, with gains capped at an "approximate limit," and expects to hold three overlapping groups of bitcoin-linked options. Investors would therefore forgo some upside in exchange for protection, a trade-off Seyffart characterized as a "buffer" bitcoin ETF structure.
BlackRock's filing cautions that the strategy does not guarantee a fixed level of protection and states the fund "does not provide a fixed Tranche Protection Start Value, Floor or Tranche Cap Value." CriptoNoticias reported that the prospectus says protection is "not immutable or guaranteed under any circumstances" and that management fees, not yet published in the draft, would reduce final gains and widen losses.
The filing arrives amid notable flows in the existing product set. CoinDesk reported that U.S. spot bitcoin ETFs attracted $526.6 million on Monday, the largest daily net inflow in nearly a month, driven entirely by IBIT, which took in $665.2 million according to SoSoValue data. Fidelity's FBTC lost $83.6 million and Grayscale's GBTC shed $54.9 million. CoinDesk calculated that the inflow more than offset the prior week's $228.5 million of withdrawals, though bitcoin ETFs remain about $90.5 million in negative territory for October. CryptoSlate noted that Ethereum ETF assets fell from $17.79 billion to $14.7 billion amid sustained redemptions, with U.S. spot Ethereum ETFs losing another $103.3 million on Oct. 19.
