BlackRock Files Bitcoin ETF Offering Downside Protection With Upside Exposure to IBIT
BlackRock filed on October 19, 2026 with the US Securities and Exchange Commission for a new bitcoin ETF linked to its iShares Bitcoin Trust (IBIT). The product uses a covered put-option strategy to provide downside protection within a pre-set band while preserving capital-appreciation upside. The new fund would be BlackRock’s third bitcoin-linked product, underscoring how mainstream asset managers are leaning on structured vehicles to expand crypto’s reach into more conservative investor pools.
