Bitwise CIO Matt Hougan said that a U.S. spot Ethereum ETF could attract $15 billion worth of net inflows in the first 18 months after listing. Hougan compared Ethereum's relative market capitalization to Bitcoin, and he expects investors to allocate according to the market capitalization of the Bitcoin spot ETF and the Ethereum spot ETF ($1.2 trillion and $405 billion). This would provide a weight of about 75% for the Bitcoin spot ETF and about 25% for the Ethereum spot ETF. Currently, assets managed through spot Bitcoin ETFs have exceeded $50 billion, and Hougan expects that figure to reach at least $100 billion by the end of 2025. This number will rise as the product matures and is approved on platforms such as Morgan Stanley and Merrill Lynch.
