Bitcoin ETFs draw $987M weekly as three-week inflows reach $3.8B
US spot bitcoin ETFs pulled in $986.9 million in net inflows last week, extending a three-week run that ranks as the strongest stretch of 2026, SoSoValue data shows. BlackRock's iShares Bitcoin Trust (IBIT) led the funds with $691.5 million for the week ended Sept. 5, up from $924.5 million the prior week.
"Sustained ETF inflows suggest institutional capital is steadily rebuilding exposure to bitcoin, creating genuine spot demand rather than relying on leverage-driven speculation," Dominick John, analyst at Zeus Research, said.
The three-week total reached $3.8 billion, the category's best such period this year, after a difficult start to 2026 when heavy outflows left year-to-date net flows roughly $1 billion in the red. Total net assets across the US spot bitcoin ETF suite stood at $101.3 billion on Sept. 5, after briefly touching $103.3 billion the prior session, with cumulative inflows since launch at $55.6 billion. Weekly trading volume of $14.5 billion was down from nearly $19 billion the week before.
The inflow pace cooled into the weekend. Funds recorded $174.6 million on Sept. 5, a sharp step down from the roughly $731 million that entered a day earlier, with IBIT contributing $117.4 million, about 67 percent of the day's total, and Fidelity's Wise Origin Bitcoin Fund (FBTC) adding $57.2 million, per Farside Investors. Every other US spot bitcoin ETF reported zero net flows that session.
Ether and XRP ETF flows retreat
The bitcoin rebound came as competing products pulled back. US spot ether ETFs added $218.4 million last week, down 74 percent from $824.4 million the prior week, while XRP ETFs drew $19 million versus $110.5 million, SoSoValue data shows. Both still extended positive streaks — ether funds logged a third straight weekly inflow — and remain net positive for the year at roughly $863 million and $515 million, respectively. The divergence points to allocation shifting unevenly across asset classes rather than a uniform institutional retreat.
Bitcoin hovered near $80,000 after touching a high of about $81,700 on Sept. 4, then slid to briefly below $79,000 on Sept. 5 following a stronger-than-expected US jobs report. The asset traded at $79,951 as of 21:35 UTC Sunday, little changed over 24 hours. August nonfarm payrolls of 162,000, above the roughly 56,000 expected, raised questions about how quickly the Federal Reserve can cut rates.
"Holding $80,000 keeps the structure constructive," said John, who sees bitcoin grinding toward $82,000-$85,000 but expects the next move to be macro-driven. Traders are watching Sept. 10 jobless claims and Sept. 11 consumer price index data for signals on Fed policy, yields and liquidity ahead of the central bank's Sept. 15-16 meeting. "A supportive macro backdrop could extend the rally, while a hotter inflation print would be the key downside risk," said Min Jung, research associate at Presto Research.
The question for allocators is whether the IBIT-led pace — roughly $1 billion a week — can hold once the macro calendar turns, and whether ether and XRP funds stabilize after their weekly declines. A hot CPI reading would test whether the current inflows reflect durable institutional demand or a catch-up trade that fades as rate expectations shift.
