Bitcoin ETFs Turn Positive for 2026 After Record Weekly Inflow

U.S. spot bitcoin ETFs drew $2.4 billion in net inflows last week, marking their strongest weekly performance in nearly a year and flipping their 2026 year-to-date flows positive. The turnaround comes just two months after the funds sat roughly $5.8 billion in negative territory in mid-July. Ether funds also rebounded, pulling in $689.9 million after the previous week’s outflows.

Monday Drives Bulk of Weekly Inflows

Most of last week’s bitcoin ETF money arrived on Monday, when the 12 tracked funds took in $999 million, their largest single-day inflow since October 2025. Daily amounts then declined steadily through the week, though inflows continued for a seventh consecutive day. BlackRock’s IBIT led all funds with $1.2 billion for the week, followed by Fidelity’s FBTC at $701.7 million.

Treasury Buybacks Cited as Key Driver

Analysts linked the surge to Treasury Department plans increasing bond buybacks, injecting fresh liquidity into markets. Cumulative bitcoin ETF inflows since launch now total $57.6 billion, with net assets reaching $108.4 billion. Solana funds also set records, drawing $86.7 million in a single day, while XRP ETFs added $75.6 million for the week.
