Bitcoin ETFs Add $346.9M as Inflows Drop 51.5%
Four funds recorded positive flows on September 23. IBIT and FBTC supplied 89.2% of the total, while daily net inflows fell 51.5% from the previous session.
Key Takeaways
- U.S. spot Bitcoin ETFs recorded $346.9 million in net inflows for September 23, their fifth positive session in a row, according to Farside Investors.
- IBIT and FBTC contributed 89.2% of the total. Four of the 12 funds in Farside's table had positive flows, down from six a day earlier.
Details
Net inflows into U.S. spot Bitcoin exchange-traded funds fell 51.5% from September 22's $714.7 million, based on Farside Investors' rounded daily figures. The reporting date is the U.S. trading session of September 23, 2026, on Eastern Daylight Time (EDT, UTC−4).
BlackRock's IBIT led with $166.3 million, followed by Fidelity's FBTC at $143.2 million. Morgan Stanley's MSBT recorded $32.4 million and ARK 21Shares' ARKB $5.0 million. The other eight funds showed zero net flow in the table at the time checked; none showed a net outflow.
Together, IBIT and FBTC contributed $309.5 million. Dividing that amount by the $346.9 million aggregate gives their 89.2% share of the day's net inflows across the 12 tracked funds. This is a flow share, not a share of assets under management.
The positive run covers September 17, 18, 21, 22 and 23. Farside's automatically updated table is an aggregated data source, rather than an issuer filing. Its displayed figures may be revised; the amounts and calculations here use that table consistently.
Market Analysis
The fifth positive session extends the inflow streak, but the daily amount and the number of funds receiving inflows both declined. Those measures give a more qualified picture than the streak alone: positive flows persisted, with most of the latest total concentrated in two funds.
Net flow data does not identify who invested or establish why Bitcoin's price moved. For the next session, the useful comparison is whether the total recovers and whether inflows spread beyond the current four funds.
