Crypto investment funds attracted another $1.3 billion last week, extending their positive-flow streak to six consecutive weeks and bringing cumulative inflows over that period to approximately $6.8 billion.

The latest inflow followed roughly $3.3 billion in the previous week and lifted the four-week average to about $1.5 billion per week, its highest level since November 2025. The six-week sequence represents a sharp reversal from the heavy redemptions that pressured digital-asset products earlier this year.

BlackRock’s iShares Bitcoin Trust remained the primary contributor to the recovery. IBIT absorbed approximately $3.4 billion during the six-week period, representing about half of total crypto-fund inflows over the same 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, making it by far the largest U.S.-listed spot Bitcoin product.

The concentration of recent inflows in IBIT continues a pattern observed during the market’s recovery. The fund previously led a seven-session Bitcoin ETF inflow streak in July, when nearly $1 billion entered U.S. spot Bitcoin products as BTC recovered from its midyear lows.

Although the current six-week fund-flow streak extends beyond IBIT, BlackRock’s product remains the largest individual contributor. Its regulated structure provides brokerage and institutional accounts with direct exposure to Bitcoin’s price without requiring investors to manage private keys or onchain custody.

Broader Fund Flows Diverge From Recent U.S. Bitcoin ETF Activity

The $1.3 billion weekly figure covers the broader universe of crypto investment funds and should not be treated as equivalent to daily flows from U.S. spot Bitcoin ETFs.

U.S. spot Bitcoin ETFs recorded approximately $463 million in net redemptions between September 8 and September 11, reversing the positive weekly sequence recorded through early September. The shorter-term pullback followed several stronger weeks, including an $854 million Bitcoin ETF inflow in early August.

The difference reflects separate reporting universes and time periods rather than contradictory capital-flow figures. Demand across the broader crypto-fund market remained positive for six weekly periods even as U.S. spot Bitcoin products posted several negative sessions during the latest trading week.

For assessing whether the broader recovery is continuing, both measures provide relevant but distinct information: weekly crypto-fund totals show the direction of aggregated product flows, while U.S. ETF data provides a more specific view of recent activity in spot Bitcoin vehicles. The figures therefore need to be compared using the same reporting period and fund universe.

Four-Week Average Reaches Highest Level Since November

The increase in the four-week average to approximately $1.5 billion marks a further improvement from the severe fund outflows recorded during the second quarter. U.S. Bitcoin ETFs experienced a record $1.79 billion weekly withdrawal in late June as investors reduced exposure during the market drawdown.

Six consecutive positive weeks have since improved the broader flow picture, with $6.8 billion entering crypto funds during the period. IBIT accounted for approximately $3.4 billion, while the remaining inflows were distributed among other Bitcoin, Ethereum and digital-asset investment products.
