BlackRock Files for Third Bitcoin ETF With Options-Based Downside Protection
BlackRock filed with the SEC on October 19 for the iShares Bitcoin Managed Protection ETF (PBIT), a buffer fund that would use options on IBIT to limit losses to roughly 10% per tranche while capping gains.
Why it matters
The filing signals BlackRock's continued expansion in crypto ETFs beyond simple spot exposure, introducing defined-outcome strategies that could attract risk-averse investors. It also highlights the asset manager's absence from spot ETFs for other cryptocurrencies like Solana and XRP.
