The recent approval of spot Ethereum (ETH) ETFs by the SEC has sparked significant discussion among analysts and investors. Bloomberg ETF analyst James Seyffart predicts that demand for spot Ethereum ETFs could reach 20% to 25% of the demand for spot Bitcoin (BTC) ETFs, given Ethereum's market size is about 30% of Bitcoin's. However, institutional interest in ETH ETFs appears to be lower, with ETH making up less than 15% of assets in Hong Kong. Analyst Eric Balchunas suggests that ETH ETFs might capture only 10-15% of BTC's trading volumes initially. The launch of these ETFs could happen as early as mid-June or by August, but they still require another review stage for the S-1 documents. The SEC approved eight 19b-4 filings for these ETFs. The approval of ETH ETFs is seen as a move that could provide exposure to a tech platform for smart contracts, distinguishing it from Bitcoin ETFs, which are viewed as digital gold. Despite the approval, the price of ETH has not surged as expected, with commentators citing various reasons for this lack of immediate price movement.
