BlackRock Bitcoin ETF's Partial Downside Protection Strategy
BlackRock filed for the iShares Bitcoin Managed Protection ETF (PBIT), an options-based Bitcoin ETF with partial downside protection. PBIT would not directly hold Bitcoin but use options tied to IBIT and similar instruments. IBIT, BlackRock's directly held Bitcoin ETF, saw $665.2 million in inflows on October 19, 2026. The protection strategy involves buying and selling call options, limiting gains but reducing downside risk.
