Cointelegraph and UNLOCK Blockchain give different totals for the September 15 Bitcoin ETF outflow and disagree on whether BlackRock’s IBIT contributed a reported figure.
What all sources agree on
Fidelity’s FBTC saw outflows of $214.8 million
Grayscale’s GBTC saw outflows of $44.1 million
ARK 21Shares’ ARKB saw outflows of $17.4 million
Bitwise’s BITB saw outflows of $12.4 million
The prior day saw $159.9 million in inflows
The U.S. Senate failed to advance the CLARITY Act, falling short of the 60 votes required
Data is attributed to Farside
The outflows were compared to a roughly $469 million outflow on June 24
Where the reports disagree
1Total net outflow figure for the day
The 13 US-listed funds saw a net $450.4 million outflow on Tuesday, after attracting $159.9 million on Monday, according to data from Farside.
U.S. spot Bitcoin exchange-traded funds recorded $288.7 million in net outflows on September 15, reversing the $159.9 million in inflows recorded a day earlier.
On September 14, BlackRock’s IBIT recorded $134.3 million in inflows, while FBTC brought in $53.3 million before reversing course the following day. Farside did not report a finalized IBIT figure for September 15.
What would settle it: Farside Investors’ published daily ETF flow data for September 15, specifically the IBIT line item
What to make of it
Treat the FBTC, GBTC, ARKB, and BITB figures and the Senate CLARITY Act vote as established; the overall outflow total and IBIT’s role in it remain unresolved between these two reports until Farside’s underlying data for that day is checked directly.
