US spot Bitcoin exchange-traded funds (ETFs) posted their best weekly inflows in nearly 10 months, drawing close to $2 billion as Bitcoin’s price surged over the same period. According to SoSoValue data, the week ending Friday saw $1.92 billion in net inflows—the strongest result since early 2026.
The comeback in demand appears to have been broad rather than isolated. ETF analyst Nate Geraci said on Sunday that spot Ether ETFs also attracted roughly $700 million, with Bitcoin and Ether funds each posting their strongest weekly inflows since October 2025.
Key takeaways
- US spot Bitcoin ETFs pulled in $1.92 billion in net inflows for the week ending Friday, their strongest weekly performance in nearly 10 months, per SoSoValue.
- Bitcoin rose more than 20% over the week, briefly breaking above $79,000 after starting near $63,000, according to CoinGecko.
- Despite last week’s rally, US spot Bitcoin ETFs remain down for 2026 with about $2.91 billion in net outflows so far.
- BlackRock’s IBIT led the rebound with about $1.33 billion in net inflows across five consecutive trading days, according to Farside Investors.
Inflows rebound as Bitcoin accelerates
The latest ETF surge arrived after a stretch of uneven flows that had weighed on sentiment around the category. SoSoValue’s weekly figures show that capital returned quickly once spot Bitcoin gained momentum, with the week ending Friday delivering $1.92 billion in net inflows.
CoinGecko data cited in the report shows Bitcoin climbed more than 20% last week, moving from roughly $63,000 to briefly exceed $79,000 on Friday. That price strength matters because it often changes investor behavior at the margin—buyers become more willing to allocate into spot products when returns are visibly improving.
Geraci’s comments suggest the demand was not limited to Bitcoin alone. He said spot Ether ETFs drew about $700 million, and that both Bitcoin and Ether funds logged their strongest weekly inflows since October 2025.
2026 still shows persistent outflows
While last week was a clear improvement, the broader picture for 2026 remains negative. The report notes that US spot Bitcoin ETFs are down overall by about $2.91 billion in net outflows so far this year.
Flow patterns have been especially weak around mid-year. The funds recorded their heaviest monthly outflows in June at $4.51 billion, following $2.43 billion in withdrawals in May. In contrast, August has turned more supportive, with $2.38 billion in net inflows through Friday, making it the strongest inflow month of 2026 to date.
That contrast is important for investors watching whether the ETF complex is transitioning from a sell-the-rally posture to a sustained buying trend. A single strong week can happen within a broader downcycle, but sustained monthly inflows would signal a more durable shift.
The October 2025 inflow cycle—and why comparisons matter
Earlier ETF strength also preceded a major market shock. During the last significant inflow wave in October 2025, the funds attracted $3.42 billion. The report links that period to the Oct. 10 crypto market crash, which it says triggered the largest liquidation event in the industry’s history—wiping out about $19 billion in leveraged positions within 24 hours.
Bitcoin’s drawdown over the same broad interval provides additional context. Since Oct. 6, when the asset traded near $124,700, the report states Bitcoin has fallen roughly 38%.
These comparisons don’t imply a repeat outcome, but they do highlight a recurring dynamic: ETF inflows can accelerate during bullish price phases, yet high leverage in the broader market can still produce abrupt reversals. For traders and portfolio managers, the practical takeaway is that ETF flow strength should be assessed alongside overall market positioning and volatility, not treated as a standalone predictor.
IBIT drives the resurgence with shifting daily momentum
The rebound last week was heavily influenced by BlackRock’s IBIT. According to Farside Investors data cited in the report, IBIT accounted for about $1.33 billion in net inflows over five consecutive trading days.
The product’s daily flow profile also showed a noticeable ramp-up before cooling. The report states IBIT’s daily inflows rose from $160.2 million on Monday to $503 million on Thursday, before easing to $239.3 million on Friday.
Bloomberg ETF analyst Eric Balchunas characterized the flow sequence as a “classic Flipping the Bird pattern” and suggested it represented a bullish signal. While interpretations of daily flow patterns can vary, the market relevance is straightforward: when large allocations repeatedly enter an ETF on consecutive sessions, it often reflects active demand rather than a one-day reaction.
For readers tracking whether this week’s inflow surge is the start of a broader trend, IBIT’s trajectory is likely to remain a key point of observation—both in terms of whether consecutive inflow days persist and whether the category-wide momentum extends beyond one or two products.
Going forward, investors should watch whether August’s inflow strength continues and whether the weekly pattern holds in the coming sessions; the category is still net-negative for 2026 overall, so follow-through beyond a single standout week will be the clearest test of whether demand is truly regaining durability.
