US spot Bitcoin ETFs recorded a $120M net outflow on September 9, with ARKB and GBTC accounting for $78M and $27.2M of that decline respectively. In contrast, spot Ethereum ETFs posted a $34.7M inflow during the same period, driven primarily by BlackRock's ETHB with $22.9M in net flows.
The divergence reflects a near-term institutional rotation favoring Ethereum over Bitcoin. While the single-day Bitcoin outflow marks a reversal from recent accumulation patterns, the $120M movement remains modest relative to the cumulative $55.45B inflow base into US spot Bitcoin ETFs.
Whether this represents a broader institutional shift or a temporary rebalancing remains unclear. The magnitude of daily flows can fluctuate significantly, and one day's activity does not establish a sustained trend. Monitoring whether outflows from flagship Bitcoin products accelerate or stabilize will be key to assessing the durability of this preference change.
