The Wall Street Journal reported that individual-stock options trade about $700 billion a day in underlying share value, citing investment manager Carrick Lane. Bitcoin more than doubled during the 2021 options boom, but Bitcoin has not repeated that rally so far.

SoSoValue reported that U.S. spot Bitcoin ETFs recorded $65.40 million in net outflows on October 12. Analysts say 2026 retail flows are concentrating in a handful of stocks rather than spreading across the market.
