Bitcoin ETFs draw nearly $1 billion in one day

US spot bitcoin exchange-traded funds recorded about $999 million of net inflows, their largest daily intake in roughly 11 months. The move extended a sharp reversal from the outflows seen earlier in the year.

BlackRock's IBIT led the session with about $381 million, followed by ARK 21Shares' ARKB at roughly $289 million and Fidelity's FBTC at about $239 million. The inflows came as bitcoin traded above the levels reached earlier in September.

ETF flows measure money moving through the listed products rather than all demand for bitcoin. They provide a visible channel for regulated investment exposure, but do not capture trading on crypto exchanges, over-the-counter desks or direct custody.
