Bitcoin ETFs Flooded with $2.4B in Largest Inflow Week Since October 2025

Spot Bitcoin ETFs saw their best week in nearly a year, attracting $2.4 billion in net inflows for the week ending September 25.

This influx of capital marked a significant turnaround from the deficit of approximately $5.8 billion that spot Bitcoin ETFs faced as recently as mid-July.

BlackRock's iShares Bitcoin Trust (IBIT) was the largest recipient, pulling in around $1.2 billion, followed by Fidelity's FBTC with roughly $702 million in net inflows.

The daily pattern showed inflows peaking at nearly $999 million on Monday before fading to $135 million on Friday, which coincided with Bitcoin briefly touching $87,000 early in the week before retreating to the $83,000 to $84,000 range.
