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.
