Spot Ethereum ETFs in the US have amassed over 5% of Ethereum’s supply, according to blockchain data from SoSoValue. These ETFs hold 6.3 million ETH worth $26.7 billion, representing approximately 5.1% of the circulating ETH supply. This growth is remarkable given that these ETFs are just a few weeks old. However, there was a notable outflow of $196.6 million from spot Ethereum ETFs on Monday, marking the second-largest daily outflow since their launch, and highlighting a potential shift in investor sentiment. Meanwhile, Bitcoin spot ETFs also experienced a similar outflow, with $121.8 million leaving in a single day. This data provides insight into market dynamics as both ETH and BTC ETF activity fluctuates.
