Bitcoin ETFs Post Strongest Week Since October 2025, Turning 2026 Net Flows Positive

Bitcoin exchange-traded funds (ETFs) saw their strongest week since October 2025, attracting $2.4 billion in net inflows during the week ending September 25. This surge has turned 2026's net flows positive at $934.1 million, reversing a deficit that stood near $5.8 billion two months earlier.

The demand for Bitcoin ETFs was led by BlackRock's IBIT, which collected $1.2 billion in the week, its second-largest weekly intake since October 2025. Fidelity's FBTC also performed well, adding $701.7 million, while Ark and 21Shares' ARKB received $294.7 million.

Ether ETFs saw a significant turnaround from their previous outflow of about $140 million, with $689.9 million in inflows during the week. This has taken 2026's net additions to around $1.6 billion. Solana ETFs also performed well, recording a record $86.7 million inflow on Friday, pushing weekly demand to $188.2 million.
