Ethereum exchange-traded funds (ETFs) have experienced unprecedented inflows in August 2025, with a record single-day inflow surpassing $1 billion on August 12. This surge marks the largest net inflow day in history for Ethereum ETFs, significantly outpacing Bitcoin ETFs, which recorded inflows of around $65.9 million on the same day. Over the subsequent days, Ethereum ETFs continued to attract substantial investment, with inflows of approximately $524 million on August 13 and $704 million on August 14, the latter being the third-largest inflow day on record. Major institutional investors such as BlackRock and Fidelity have been leading buyers, with BlackRock purchasing $639 million and $476 million on different days, and Fidelity acquiring $155 million worth of Ethereum ETFs. The total net assets of spot Ethereum ETFs have surged from $8.9 billion to $23.4 billion, a 165% increase over 13 weeks of consecutive inflows. The inflows into Ethereum ETFs have outpaced Bitcoin ETFs for several weeks, with $2.3 billion flowing into Ethereum ETFs over five trading days compared to significantly lower Bitcoin ETF inflows. These developments reflect growing institutional interest in Ethereum as a programmable store of value and a key asset in decentralized finance (DeFi) and non-fungible tokens (NFTs). The inflows into Ethereum ETFs have also exceeded the net issuance of ETH tokens on the network, indicating strong demand from institutional investors.
