U.S. spot Bitcoin exchange-traded funds pulled in $433 million on Friday, their largest single-day inflow since Sept. 3, enough to keep the category from posting a second straight weekly loss.
SoSoValue data showed the funds ended the week of Sept. 18 with net inflows of $6.2 million.
Friday reversed a week that had been deeply negative
The weekly total was razor-thin because the category had spent most of the week in the red. Funds brought in $160 million on Monday, then saw $450.3 million in outflows on Tuesday and another $296 million on Wednesday. Thursday added $159.5 million, but the group was still down $426.8 million going into Friday.
That made Friday’s $433 million inflow the decisive move of the week.
FBTC led on Friday, while IBIT led for the week
Fidelity’s FBTC accounted for $310.7 million of Friday’s total. BlackRock’s IBIT contributed $108.4 million.
Across the full week, the ranking flipped. IBIT posted $120.7 million in net inflows, compared with $79.9 million for FBTC. The remaining funds together lost about $194.4 million.
Bitcoin moved back above $81,000
The late-week shift in demand came alongside a rally in Bitcoin. BTC rose more than 6% on Friday and held the gain, pushing back above $81,000 after spending two weeks below that level.
It reached $82,100 early Monday and was last trading near $81,600.
Khing Oei, founder and CEO of Dutch bitcoin treasury firm Treasury, wrote on X that the current move is driven by allocation, adding that it usually happens slowly and then all at once.
Ether funds ended a four-week inflow streak
Ether funds did not follow the same path. They recorded $140 million in net outflows for the week, ending a four-week streak that had collected $1.94 billion, even though they still brought in $143.8 million on Friday.
Trading volume rose in both ETF categories
Trading volume increased sharply. Bitcoin fund volume reached $16.17 billion, up from $8.77 billion the week before. Ether fund volume rose to $6.82 billion from $5.14 billion.
Year-to-date flows and policy backdrop
Even with last week’s narrow positive finish, Bitcoin ETFs are still down about $1.45 billion for 2026. The category holds $102.53 billion in net assets.
Bloomberg ETF analyst Eric Balchunas said Thursday that holders showed “incredible intestinal fortitude” by sitting through a 50% drawdown.
The rebound in Bitcoin ETFs came at the end of a difficult week for the industry. The Clarity Act failed a Senate procedural vote on Tuesday, leaving the Securities and Exchange Commission and the Commodity Futures Trading Commission to write rules on their own. On Wednesday, the Federal Reserve raised rates by a quarter point to 3.75%-4%, its first increase since July 2023.
