Bitcoin ETFs erase 2026 losses after $2.4 billion weekly inflow

The dollar swing is worth spelling out. The funds sat roughly $5.8 billion in the red as recently as July 13; after last week’s inflow they stood about $934.1 million in the green, a reversal of approximately $6.7341 billion ($5.8 billion plus $934.1 million). That moved cumulative net inflows since launch to $57.6 billion, with net assets at $108.4 billion as of Friday.

The seven-day run started Sept. 17. According to Decrypt, U.S. spot bitcoin ETFs added $134.5 million on Friday alone, pushing the streak’s total to roughly $2.98 billion. The gap reflects different trackers and cutoff points, not a contradiction — both place the funds back in positive territory after a July hole of roughly $5.7 billion to $5.8 billion.

The strongest single session was Sept. 21. The 12 publicly traded bitcoin ETFs tracked by SoSoValue drew $999.0 million that day, their largest daily haul since Oct. 6, 2025. Nate Geraci, president of NovaDius Wealth Management, wrote: “Monday’s $1bil inflow was 9th largest ever.”

BlackRock’s IBIT led the week with $1.2 billion — exactly half the reported $2.4 billion total. Fidelity’s FBTC added $701.7 million, roughly 29.2% of the week’s intake ($701.7 million divided by $2.4 billion), and its largest weekly figure since the week of Sept. 8, 2025. Ark and 21Shares’ ARKB took in $294.7 million, nearly all of it on Monday. Morgan Stanley’s MSBT drew $203.3 million, its biggest week since launching in April. Combined trading volume across the products still fell, though — $15.0 billion versus $16.2 billion the prior week, even as assets and net inflows climbed.

The broader crypto ETP picture improved as well. Spot ether ETFs added $689.9 million after losing roughly $140.0 million the week before, including $270.0 million on Monday, their largest daily inflow since Oct. 7, 2025. BlackRock’s ETHA led with $326.2 million for the week; Fidelity’s FETH added $174.0 million; Grayscale’s Ethereum Mini Trust drew $100.3 million. Ether products finished up about $1.6 billion for the year, with $17.8 billion in net assets and $13.9 billion in cumulative inflows since launch — though weekly trading volume dropped to $4.8 billion from $6.9 billion.

Solana funds set a record. U.S. spot Solana ETFs took in $86.7 million on Friday, their largest single-day inflow since launching in late October 2025, and $188.2 million for the week — second only to their $199.2 million launch week. Combined assets reached $1.5 billion, up from $1.2 billion seven days earlier. Spot XRP ETFs added $75.6 million for the week, and Grayscale’s Zcash fund, ZCSH, briefly crossed $1.0 billion in net assets on Thursday.

The next weekly flow report will show whether the streak continues or the reversal stalls.
