Bitcoin Spot ETFs See $3.8B Inflows in Peak Three-Week Run of 2026

US-listed spot Bitcoin exchange-traded funds (ETFs) extended a late-summer demand surge, logging their strongest three-week stretch of 2026. The rebound coincided with Bitcoin trading around the $80,000 level, with weekly inflows accelerating into the week ending Friday.

SoSoValue data shows the funds pulled in $986.9 million during the week ending Friday. That pushed cumulative net inflows over the past three weeks to $3.8 billion. Total net assets across the suite were $101.3 billion on Friday, after rising to $103.3 billion the prior day. Since inception, cumulative net inflows reached $55.6 billion.

Key takeaways

• US spot Bitcoin ETFs attracted $986.9 million in the week ending Friday, lifting three-week net inflows to $3.8 billion.
• Friday’s total net inflow was $174.6 million, down from a much larger Thursday surge of nearly $731 million.
• BlackRock’s IBIT led demand with $117.4 million on Friday, about 67% of that day’s inflows, per Farside Investors.
• Bitcoin ETF momentum is improving versus the prior week, but year-to-date flows remain about $1 billion negative, reflecting lingering uncertainty from earlier 2026 outflows.
• While Bitcoin inflows strengthened, spot Ether and XRP ETF flows fell sharply on a weekly basis.
