The exchange Nasdaq and BlackRock, the world's largest asset manager, plan to list options based on a spot Ethereum ETF. In a document posted on the Securities Exchange Commission's website on Tuesday, BlackRock and Nasdaq proposed changing the rules to line up and trade options based on iShares Ethereum Trust (ticker ETHA). "The exchange believes that offering trust options would benefit investors as it provides investors with an additional, relatively low-cost investment vehicle that gives them access to the Ether spot, while also providing a hedging instrument that meets their investment needs in Ether products and positions," the document reads. Comments on the proposal will be published within 21 days. Bloomberg analyst James Seyffart wrote on X on Tuesday that the SEC could make a final decision on the proposal by early April 2025.
