On August 18, 2025, the spot ETF market witnessed remarkable movements. Ethereum spot ETFs recorded the second-largest outflow in history, with a total net outflow of $196.62 million. On the same day, Bitcoin spot ETFs also saw significant fund withdrawals, registering a $121.8 million net outflow.
Historic Outflow in Ethereum Spot ETFs
Ethereum spot ETFs experienced a net outflow of $196.62 million in a single day on August 18, marking the second-largest outflow ever recorded. This highlights institutional investors’ short-term tendency to avoid risk. In particular, U.S. monetary policy, global market uncertainties, and Ethereum’s price volatility are cited as key factors behind this move.
Bitcoin ETFs Are Losing Ground
Bitcoin spot ETFs also recorded a $121.8 million net outflow on the same day. This indicates that investors are acting cautiously on both the Bitcoin and Ethereum fronts. According to market analysts, this development could put short-term pressure on Bitcoin’s price, but long-term investors are not expected to alter their strategies.
The Sole Net Inflow: Bitwise Bitcoin ETF (BITB)
On a day dominated by outflows, the Bitwise Bitcoin ETF (BITB) stood out as the only exception, recording a net inflow. This highlights investor confidence in Bitwise’s offerings and the strategic advantages of its products.
The massive outflows on August 18 underscore the high volatility that still characterizes the Ethereum and Bitcoin ETF markets. However, the net inflow into the Bitwise ETF shows that confidence has not been entirely lost and that investors remain selective in their allocations.
