US spot Bitcoin ETFs log $527M net inflow, largest since September
BlackRock's IBIT pulled in $665.2 million, outweighing redemptions at Fidelity and Grayscale as other funds stayed flat.

US spot Bitcoin exchange-traded funds attracted $527 million in net inflows, the strongest single-day showing for the group since September, according to Cointelegraph.
BlackRock's IBIT accounted for the bulk of the activity, drawing $665.2 million on its own. Because the group total is smaller than IBIT's haul, the remaining funds were net negative or flat for the session.
Where the money went
- IBIT (BlackRock): $665.2 million in inflows
- Fidelity and Grayscale funds: net withdrawals
- Remaining funds: no net flows recorded
- Group total: $527 million net inflow
The split illustrates how concentrated flows remain in the largest spot Bitcoin fund, with gains at IBIT offsetting redemptions elsewhere rather than reflecting broad-based buying across the category. Days of heavy issuance at a single fund can mask continued outflows from older, higher-fee products.
Flows into spot Bitcoin ETFs are watched as one gauge of US institutional demand for the asset, though single-day figures can swing sharply and do not on their own establish a trend.
