Bitcoin ETFs buy $1.92B this week, largest stash in 10 months

US spot Bitcoin ETFs just had their best week in nearly a year. The funds collectively pulled in $1.92 billion in net inflows for the week ending August 22, a pace of buying that hasn’t been matched since October 2025, when ETFs attracted $2.71 billion.

The timing lines up with Bitcoin’s price ripping roughly 25% higher over the same stretch, with the asset approaching the $80,000 level.

Five straight days of green

Every single trading day posted positive net inflows. Monday opened with $297.6 million flowing in, followed by $189.3 million on Tuesday. Wednesday kicked things up to $517.2 million, Thursday hit the week’s peak at $606.3 million, and Friday cooled slightly to $307.5 million.

BlackRock’s iShares Bitcoin Trust (IBIT) continued to do what it does best: absorb the lion’s share of demand. The fund captured $503 million on its peak day. Fidelity’s FBTC, Bitwise’s BITB, and ARK 21Shares’ ARKB also contributed meaningfully to the week’s total.

Why the flood of capital now

US Treasury buyback expansions during the week helped push yields lower, making risk assets more attractive by comparison. Short-covering added fuel. As Bitcoin’s price began climbing, traders who had been betting against it were forced to buy back their positions, creating a feedback loop that accelerated the rally.

The broader crypto market benefited too. Ethereum spot ETFs pulled in roughly $693 million to $697 million during the same period.

Total assets under management across US spot Bitcoin ETFs have now climbed to approximately $96 billion.

What the institutional playbook looks like from here

The October 2025 high-water mark of $2.71 billion in weekly inflows remains the number to beat. Spot Bitcoin ETFs have been trading since January 2024. After a period of outflows in the earlier part of 2026, culminating in an eight-week losing streak that ended in July, the latest inflow data marks a strong turnaround in investor confidence.
