Bitcoin ETF News: BlackRock’s IBIT Dominates With 62% of Inflows

U.S. spot Bitcoin ETFs attracted $730.8 million in net inflows on September 3, with BlackRock’s IBIT accounting for $454 million of the total. The fund alone captured well over half of the day’s combined inflows.

The figures provide a fund-level breakdown of where investors added or withdrew capital during the session. Because ETF flow data can be updated when delayed reports arrive, the daily numbers should be viewed as tracker figures for the reported trading day rather than final immutable totals.

IBIT Accounts for Most of the Bitcoin ETF Inflows

BlackRock’s IBIT generated a $454 million net inflow on September 3, significantly exceeding the other Bitcoin ETFs that posted gains that day.

ARK 21Shares’ ARKB ranked second with $137.7 million, followed by Fidelity’s FBTC with $74.4 million. Combined with IBIT, the three funds represented the majority of the positive flows recorded during the session.

Other Bitcoin ETF products also registered net inflows. Grayscale’s Bitcoin Mini Trust, identified as BTC in the tracker, received $48.8 million. Bitwise’s BITB attracted $24.8 million, while Grayscale’s GBTC brought in $8.2 million. Morgan Stanley’s MSBT recorded another $7.7 million.

Not every fund experienced inflows. VanEck’s HODL posted a $19.6 million net outflow, while WisdomTree’s BTCW saw $5.2 million leave the fund.

Franklin’s EZBC, Invesco Galaxy’s BTCO and CoinShares’ BRRR each recorded no net flow for the day according to the tracker.

The heavy concentration in IBIT provides important context behind the $730.8 million overall figure. While the combined ETF market can post a strong daily inflow, individual funds may experience very different results. In this case, a significant portion of the total came from a single product.

A single trading session also does not necessarily establish a longer-term trend. Historical tracker data show that daily Bitcoin ETF flows can fluctuate considerably, with strong inflow sessions often followed by weaker or negative days.

The tracker’s daily figures represent the net amount of creations and redemptions recorded across the funds. For investors analyzing September 3, three factors are particularly relevant: the total net inflow, how that capital was distributed among ETF issuers, and the possibility that the figures could be revised later.

Coinfuty’s tracker covers daily creations and redemptions, total net assets, Bitcoin held by each fund and premiums or discounts to net asset value. The platform states that its figures are updated once per U.S. trading day. It also notes that a dash may mean a fund has not yet reported its data rather than having recorded zero flows.
