American exchange-traded funds investing directly in Ether $ETHUSD have recently demonstrated the longest sequence of daily inflows in the current year. This trend marks a renewed interest among institutional investors for the second-largest cryptocurrency. Over the course of 14 consecutive trading sessions, a collective of nine ETFs has amassed $812 million. This significant growth stands out in 2025, propelled by the sharp increase of about 65% in open interest on Ether futures offered by CME Group $CME in May. These figures are approaching all-time highs, indicating a shift in investor sentiment.
