Key Takeaways
- • US spot Bitcoin ETFs recorded $986.9 million in net inflows last week, marking the third consecutive week of positive flows and pushing the three-week cumulative total to $3.8 billion—the strongest quarterly stretch of 2026.
- • BlackRock's iShares Bitcoin Trust (IBIT) dominated weekly inflows with $691.5 million, accounting for approximately 67% of Friday's daily net inflows ($117.4 million), while Fidelity's FBTC remained the only other product with positive weekly flows at $57.2 million.
- • Bitcoin is trading near $80,000 as technical indicators approach a golden cross formation, with the 50-day exponential moving average expected to cross above the 200-day EMA around September 11, though analysts note recent price strength has been partly driven by derivatives short liquidations rather than sustained institutional demand.
- • Ethereum and altcoin ETFs showed deteriorating momentum, with Ethereum ETF weekly inflows declining 74% and XRP ETF inflows dropping 83%, signaling potential rotation or profit-taking in the broader digital asset space.
Summary
US spot Bitcoin ETFs have attracted substantial institutional capital over the past three weeks, with last week's net inflows of $986.9 million exceeding the prior week's $924.5 million. The cumulative three-week inflow of $3.8 billion represents the most aggressive institutional buying activity in spot Bitcoin ETFs throughout 2026, signaling a meaningful shift in institutional sentiment toward digital assets after a period of more muted demand.
BlackRock's iShares Bitcoin Trust (IBIT) has emerged as the clear leader in this inflow cycle, absorbing $691.5 million on a weekly basis and capturing the lion's share of daily inflows on Friday alone, when it pulled in $117.4 million—roughly 67% of the day's total net inflows. Fidelity's Wise Origin Bitcoin Fund (FBTC) posted the second-largest weekly performance with $57.2 million in inflows, making it the only other spot Bitcoin ETF product to show positive weekly flows. Together, these two products accounted for the overwhelming majority of institutional capital flowing into the space.
Daily inflows exhibited significant volatility, with Friday's total net inflows of $174.6 million representing a sharp decline from Thursday's $731 million, suggesting potential cyclical consolidation after three weeks of sustained demand. Trading volume also contracted to $14.5 billion on a weekly basis, reflecting reduced market participation following the multi-week rally.
Technical developments are converging as Bitcoin approaches an anticipated golden cross formation around September 11, with the 50-day exponential moving average converging toward the 200-day EMA at current price levels near $80,000. Analysts, however, have cautioned that derivatives short liquidations contributed meaningfully to the recent price appreciation, raising questions about whether the inflows reflect genuine institutional conviction or represent tactical positioning ahead of technical barriers. Ethereum ETFs, by contrast, showed deteriorating momentum with weekly inflows declining 74%, while XRP ETF inflows dropped 83%, suggesting potential profit-taking or a rotation away from alternative digital assets.
