Bitcoin ETF Flows Reverse Midweek Outflows

Farside Investors data showed spot Bitcoin funds added $433.0 million on Sept. 18. Fidelity’s FBTC drew $310.7 million, the largest inflow among listed products. BlackRock’s IBIT followed with $108.4 million, while Bitwise’s BITB added $9.7 million.

ARK Invest’s ARKB received $1.9 million, while VanEck’s HODL added $2.3 million. No listed fund recorded an outflow during the session. The result extended the positive streak to two trading days.

However, the broader weekly picture remained mixed. The funds lost $450.4 million on Sept. 15 and $295.9 million the following day. Those sessions produced combined withdrawals of $746.3 million before demand returned. Across Sept. 17 and Sept. 18, the funds recovered $592.5 million in net inflows. That still left part of the earlier midweek withdrawals unrecovered.
