Bitcoin ETFs Add $433 Million, Ending Week Nearly Flat

Key Takeaways

• U.S. spot Bitcoin ETFs recorded $433 million in net inflows on September 18, led by Fidelity’s FBTC.
• The five-session week finished with approximately $6.1 million in net inflows after two large midweek withdrawals.

Details

Friday’s inflow brought U.S. spot Bitcoin ETFs close to balance for the week of September 14–18. Summing the five daily totals in Farside Investors’ flow table, checked September 19, produces a modest $6.1 million net gain.

Fidelity’s FBTC accounted for about $310.7 million of Friday’s total, while BlackRock’s IBIT added roughly $108.4 million. Blockonomi’s September 19 report also put the session’s net inflow at $433 million and identified Fidelity as the largest contributor.

The weekly result reflects three positive sessions against two negative ones. Monday added $159.9 million; Tuesday and Wednesday lost a combined $746.3 million; Thursday and Friday recovered $592.5 million. These are net fund-flow figures in U.S. dollars, using Farside’s displayed precision. Its automatically updated data can be revised.

Market Analysis

Friday’s net additions were concentrated in Fidelity and BlackRock. Broader participation across smaller funds would make a recovery less dependent on two products; that is the fund-level pattern to watch when U.S. trading resumes.
