Bitcoin ETFs Draw $730.8M, But One BlackRock Fund Does Most Of The Work

U.S. spot Bitcoin(BTC) ETFs drew $730.8 million on Sept. 3, while BlackRock’s IBIT captured $454 million, or about 62%, of the total.

Key Points:

• U.S. spot Bitcoin ETFs recorded $730.8 million in net inflows during the Sept. 3 trading session.
• BlackRock’s IBIT supplied roughly 62% of the total, placing it far ahead of every competing fund.
• Two funds recorded net outflows, while three showed no net flow in the reported tracker data.

BlackRock IBIT Flows

Coinglass tracker data showed IBIT dominating the session with $454 million in net inflows, representing well over half of the complex-wide total. ARK 21Shares’ ARKB ranked second with $137.7 million, while Fidelity’s FBTC added another $74.4 million.

Grayscale’s Bitcoin Mini Trust brought in $48.8 million, Bitwise’s BITB added $24.8 million, and Grayscale’s GBTC recorded another $8.2 million. Morgan Stanley’s MSBT contributed $7.7 million. Together, IBIT, ARKB and FBTC accounted for most of the positive flows reported across U.S. spot Bitcoin ETFs.

The session was not positive for every issuer. VanEck’s HODL lost $19.6 million and WisdomTree’s BTCW posted a $5.2 million outflow, while Franklin Templeton’s EZBC, Invesco Galaxy’s BTCO and CoinShares’ BRRR showed zero flow.

Bitcoin ETF Signal

The $730.8 million headline therefore masks a highly concentrated distribution of new capital. Because IBIT alone supplied about 62% of the net inflow, the aggregate result depended heavily on one product rather than a uniform increase across the market.

Coinglass treats daily figures as net creations and redemptions, and delayed reports can change those numbers after a trading session ends. That makes the Sept. 3 total a snapshot of reported activity rather than a final measure showing that investor demand will persist.

A single strong session also does not establish a longer-term trend.

Confirmation would require continued net creations across several trading days and broader participation among issuers, rather than another large total driven mainly by one fund.

The tracker’s recent history includes both inflow and outflow sessions, showing how quickly the daily picture can reverse. That context makes Sept. 3 a strong one-day return of demand, but it does not by itself establish a durable new phase for U.S. spot Bitcoin ETFs.
