Early 2024 featured frequent inflows, with some daily gains reaching about $500 million to $1 billion. However, sizeable outflows also appeared during that period. Later, October 2024 through January 2025 brought larger inflows, with some daily spikes approaching $1 billion to $1.35 billion.
Outflows still reached roughly $500 million to $700 million during that phase. From April through October 2025, inflows again appeared frequently, with several exceeding $500 million.
Ethereum spot ETFs recorded $86.95 million in net inflows on Sept. 25, extending their streak to six days. BlackRock's ETHA received $50.37 million, while ETHB attracted $31.88 million. The daily breakdown also showed ETHA receiving about 18.94K ETH and ETHB adding nearly 11.8K ETH.

FETH recorded roughly 1.8K ETH, while other listed funds showed little or no visible net flow. Over the longer period, Ethereum ETF flows remained uneven. Positive sessions reached about 200K to 220K ETH, while the deepest outflows approached 100K to 140K ETH.
Bitcoin ETF outflows became more persistent from late 2025 into mid-2026. Several red bars reached roughly $500 million to $900 million as the Bitcoin trend declined. July through September 2026 then brought several Bitcoin inflow spikes near $500 million to $1 billion. The latest readings appeared closer to neutral.
