The Chicago Board Options Exchange (Cboe Exchange), an American stock exchange, has submitted a revised application to regulators for listing options on Bitcoin and Ethereum spot ETFs. According to the document, Cboe seeks to list options based on Bitcoin and Ethereum ETFs issued by asset management companies, including Fidelity, 21Shares, Invesco, VanEck, Grayscale, Bitwise, BlackRock iShares and Valkyrie. According to the information in the Bitcoin and Ethereum options documents, the proposed rule change will classify cryptocurrency spot ETFs as "securities suitable for option trading" with commodity-based ETFs such as Goldman Sachs Physical Gold ETF and iShares Silver Trust.
