The same report says BlackRock's existing bitcoin ETF, IBIT, took in $665 million in a single day.

- BlackRock filed for a buffer bitcoin ETF.

- The information comes from a Decrypt report published on October 20, 2026.
What is confirmed
Decrypt reports that BlackRock filed for a buffer bitcoin ETF and that IBIT drew $665 million in a day. These are reported figures from the source material.
What is still unclear
The source material does not explain how the proposed buffer bitcoin ETF would work, what its structure would be, or whether the filing has been reviewed or approved by regulators. It also does not give a timeline for the filing or say when or if the fund could launch.
