Bitcoin ETFs Draw Near $1B in Single Trading Day Inflow
US spot Bitcoin ETFs recorded a significant inflow on September 21, with $998.96 million in net capital entering the funds.
The day's largest contributors were BlackRock IBIT, ARKB, and FBTC, which together accounted for nearly all of the net buying.
This is the largest single-session total for US spot Bitcoin ETFs so far this year, but it should not be confused with a cumulative flow milestone. Institutional demand can reverse quickly depending on price, macro conditions, and positioning.
