- U.S. spot bitcoin ETFs finished the week ending Sept. 18 with just $6.2 million in net inflows after a $433 million Friday rebound.
- Fidelity’s FBTC accounted for $310.7 million of Friday’s creations, with BlackRock’s IBIT adding $108.4 million.
- Spot ether ETFs posted about $140 million in weekly outflows, ending a four-week inflow streak that collected $1.94 billion.
- Zcash spot ETFs led weekly crypto product inflows with $98.2 million, outdrawing both bitcoin and ether funds.
U.S. spot bitcoin exchange-traded funds avoided a second straight negative week after investors added $433 million on Friday, Sept. 18, leaving a slim $6.2 million net inflow for the five sessions, according to The Block’s analysis of SoSoValue data.
The Friday haul was the group’s largest daily intake since Sept. 3, when the products took in $730.9 million. Even so, the weekly total is modest next to the $462.7 million in net outflows recorded the prior week. SoSoValue’s U.S. bitcoin ETF dashboard put Friday creations at $433.03 million and total net assets at $102.53 billion, with cumulative net inflows of $55.16 billion.
The path through the week was uneven. Bitcoin funds took in about $160 million on Monday before shedding $450.3 million on Tuesday and $296 million on Wednesday. A $159.5 million rebound on Thursday still left the complex down $426.8 million heading into Friday. Farside Investors’ flow table shows the same Friday split: Fidelity’s FBTC $310.7 million, BlackRock’s IBIT $108.4 million, Bitwise’s BITB $9.7 million, VanEck’s HODL $2.3 million and ARK 21Shares’ ARKB $1.9 million. Over the full week, IBIT still led with $120.7 million of net inflows, ahead of FBTC’s $79.9 million, while the remaining bitcoin products together lost about $194.4 million.
Spot ether ETFs did not finish in the black. They posted a roughly $140 million weekly outflow despite taking in $143.8 million on Friday, ending a four-week inflow run in which the funds collected a combined $1.94 billion. Farside’s ether table shows Monday’s $121.1 million inflow was followed by outflows of $142.0 million, $224.1 million and $39.3 million before Friday’s $143.7 million bounce. BlackRock’s ETHA accounted for $114.3 million of that Friday total but still finished the week with $56.1 million in net outflows; Fidelity’s FETH lost $25.8 million for the week after a $26.2 million Friday addition.
Across the broader crypto ETF complex, bitcoin and ether were not the week’s biggest magnets. BeInCrypto, citing SoSoValue, reported that Zcash spot ETFs drew $98.2 million in the week ending Sept. 18, the largest inflow among 14 crypto products, lifting Zcash ETF assets 40.5% to $914.5 million. Ether was the only major product group in outflow. Combined assets across those products rose 4.89% to $123.9 billion even as net flows across the set were roughly flat.
The late-week bitcoin creations concentrated in two issuers, and the weekly net figure sits close to zero. That leaves the flow picture constructive versus the prior week’s redemptions, but not yet evidence of a broad, multi-issuer reopening of demand.
