US spot Ethereum ETFs appeared to hold $10.36 billion shortly after trading began, a figure that initially suggested a major wave of institutional buying. Filing data reviewed by CryptoSlate indicates that the vast majority of the opening balance came from ETH already held in Grayscale’s older trusts. Rather than representing $10 billion in newly purchased assets, the launch largely transferred an existing pool of Ethereum into exchange-traded funds. The distinction is important for assessing the scale of fresh demand surrounding the products. While the ETFs began trading with substantial assets, their initial holdings did not primarily reflect capital newly entering the market. The data instead points to the conversion or movement of Grayscale’s established trust holdings into the new spot ETF structure. The development provides a clearer view of where the reported $10.36 billion came from as investors assess the early market impact of US spot Ethereum ETFs.
