Bitcoin's recent rally has spilled into the options market for BlackRock's iShares Bitcoin Trust (IBIT), with call-option volume reaching a record 1.58 million contracts on August 19, according to Goldman Sachs data shared by The Kobeissi Letter.

This surge in activity coincided with $1 billion of fresh inflows into IBIT between August 19 and August 21 as Bitcoin climbed toward $80,000.

The call skew for IBIT jumped 0.05 over three days, more than triple its average three-day move since January 2025 and the largest increase over that period.
