U.S. spot Bitcoin exchange-traded funds just posted their strongest three-week inflow stretch of 2026, drawing $3.8 billion in total net flows. The week ending September 5 contributed $986.9 million, with total net assets across U.S. spot Bitcoin ETFs reaching $101.3 billion and cumulative net inflows climbing to $55.6 billion.
BlackRock’s iShares Bitcoin Trust led Friday’s session with $117.4 million in inflows, while Fidelity’s Wise Origin Bitcoin Fund added $57.2 million. The day’s overall inflow of $174.6 million was down sharply from $731 million on Thursday, but the two-session total still reached roughly $905.4 million. Bitcoin traded near $79,716, up about 2.6% over seven days, after briefly slipping below $79,000.
By comparison, spot Ether ETF inflows fell 74% to $218.4 million for the week, and XRP ETF inflows dropped 83% to $19 million. Both remain positive for the year, with Ether ETFs at about $863 million and XRP ETFs at roughly $515 million in year-to-date net inflows, while Bitcoin ETFs are still about $1 billion negative for the year.
At the same time, Bitcoin’s 50-day exponential moving average is closing in on its 200-day EMA, with a golden cross projected around September 11 if prices hold near current levels. Analyst account Coin Bureau noted this would be the first such signal since November 2025 and said the last three completed golden crosses were followed by Bitcoin gains of 50%, 45%, and 60%, while cautioning that the signal is lagging and has sometimes reversed within weeks. Across 12 golden cross signals since 2012, Bitcoin averaged a 24.9% three-month gain.
The ETF demand is also helping Bitcoin absorb geopolitical pressure after U.S. forces struck three Iranian crude carriers and Brent crude climbed above $96. The U.S. economy added 162,000 jobs in August, pushing the probability of a September Federal Reserve rate hike to about 59%. With the August CPI report due September 11, inflation remains the next key risk for Bitcoin’s momentum.
