Bitcoin ETFs saw $159.5M inflows while Ethereum ETFs recorded $39.3M outflows on Sep 17, 2026.
Macro & Markets ·
On September 17, spot Bitcoin ETFs attracted $159 million in net inflows, with BlackRock's IBIT being the sole fund among Bitcoin ETF offerings to post positive flows. Spot Ethereum ETFs moved in the opposite direction, recording $39.2 million in net outflows on the same day, marking the third consecutive day of redemptions in that product category.
The divergence between Bitcoin and Ethereum ETF flows reflects mixed sentiment across major cryptocurrency asset classes. Bitcoin's positive inflow activity stands in contrast to sustained outflow pressure on Ethereum products, which have now extended their withdrawal streak across multiple trading sessions.
What remains unclear is whether the inflow concentration into a single Bitcoin fund signals broader institutional preference shifts or temporary market positioning ahead of other economic developments, and whether the Ethereum outflow pattern will persist beyond the three-day streak currently observed.
