US spot Ethereum exchange-traded funds attracted more than $1 billion of net new money on Monday, their largest single-day haul since launching earlier this year, according to flow trackers such as Farside and WatcherGuru. Fidelity’s fund accounted for a record $276.9 million of the inflow, while BlackRock’s ETHA product absorbed roughly $640 million. Across all issuers, trading volume topped about $2.7 billion, also marking an all-time high. The surge dwarfed the roughly $179 million that moved into US Bitcoin ETFs during the same session and extended Ethereum products’ streak to 15 consecutive weeks of net inflows, highlighting a shift in institutional demand toward the second-largest cryptocurrency. Ether traded near $4,300 after climbing about 45 % over the past month. Monday’s ETF purchases—equivalent to roughly 238,000 ETH, or 93 times the network’s net daily issuance—tightened supply further as investors weigh a potential return to the November 2021 record of $4,878.
