Crypto investment funds attracted another $1.3 billion last week, extending their run of positive weekly flows to six consecutive weeks and lifting cumulative inflows across the period to roughly $6.8 billion.
The latest intake followed approximately $3.3 billion in the previous week and pushed the four-week average to about $1.5 billion per week, its strongest level since November 2025. The sequence marks a sharp reversal from the heavy redemptions that pressured digital-asset products earlier this year.
BlackRock’s iShares Bitcoin Trust remained at the center of the rebound. IBIT absorbed about $3.4 billion over the six-week period, accounting for roughly half of the broader crypto-fund inflows during the stretch.
IBIT Remains the Largest Institutional Bitcoin Vehicle
BlackRock’s iShares Bitcoin Trust ETF held approximately $60.6 billion in net assets as of September 11, keeping it by far the largest U.S.-listed spot Bitcoin product.
IBIT’s recent inflow concentration continues a pattern seen throughout the market’s recovery. The fund previously led a seven-session Bitcoin ETF inflow streak in July, when nearly $1 billion moved into U.S. spot Bitcoin products as BTC recovered from its midyear lows.
The current six-week fund-flow run is broader than IBIT alone, but BlackRock’s product remains the largest individual contributor. Its regulated structure gives brokerage and institutional accounts direct Bitcoin price exposure without requiring investors to manage private keys or onchain custody.
Broader Fund Flows Diverge From Last Week’s U.S. Bitcoin ETFs
The $1.3 billion weekly figure covers the broader crypto investment-fund universe and should not be treated as the same measure as daily U.S. spot Bitcoin ETF flows.
U.S. spot Bitcoin ETFs recorded roughly $463 million in net redemptions between September 8 and September 11, reversing the positive weekly sequence seen through early September. That shorter-term pullback followed several stronger weeks, including an $854 million Bitcoin ETF inflow in early August.
The divergence reflects different reporting universes and time windows rather than contradictory capital-flow figures. Broader crypto-fund demand has remained positive across six weekly periods even as U.S. spot Bitcoin products experienced several negative sessions during the latest trading week.
Four-Week Average Reaches Highest Level Since November
The rise in the four-week average to approximately $1.5 billion marks another improvement from the severe fund outflows recorded during the second quarter. U.S. Bitcoin ETFs suffered a record $1.79 billion weekly withdrawal in late June as investors reduced exposure during the market drawdown.
Six consecutive positive weeks have since rebuilt the broader flow picture, with $6.8 billion entering crypto funds over the period. IBIT alone accounted for approximately $3.4 billion of that amount, leaving the remaining inflows distributed across other Bitcoin, Ethereum and digital-asset investment products.
