The SEC on October 2 approved Cboe BZX's rule change to list Volatility Shares' proposed 3x Ethereum ETF (ETHK). With $362.1 million in assets, ETHK would target about $1.09 billion of exposure, equivalent to 8,000 CME Ether futures contracts, which is CME's single-month and all-month accountability level. ETHK's first trading date is pending.
