BlackRock’s IBIT Takes the Big Bite of a $730.8M Bitcoin ETF Inflow Day—Rivals Trail or Slip

U.S. spot Bitcoin ETFs recorded $730.8 million in net inflows on September 3, according to CryptoNews’ summary of tracker data. The outlet reports that BlackRock’s iShares Bitcoin Trust (IBIT) led with $454.0 million—well over half of the day’s total. The publication notes that daily flow figures are subject to revision as late fund reports arrive and should be treated as session-level tracker data.

Where the money went

Per CryptoNews’ breakdown of the tracker, ARK 21Shares’ ARKB added $137.7 million and Fidelity’s FBTC took in $74.4 million. Several other products also posted inflows: Grayscale’s Bitcoin Mini Trust (listed as BTC in the tracker) added $48.8 million; Bitwise’s BITB, $24.8 million; Grayscale’s GBTC, $8.2 million; and Morgan Stanley’s MSBT, $7.7 million.

Who saw outflows or no change

The daily snapshot was not positive across every product. VanEck’s HODL recorded a $19.6 million net outflow, and WisdomTree’s BTCW showed a $5.2 million net outflow, according to the same tracker view cited by CryptoNews. Franklin’s EZBC, Invesco Galaxy’s BTCO, and CoinShares’ BRRR each showed zero flow in the tracker for the date.

Concentration matters—and so do revisions

CryptoNews emphasizes that the concentration in IBIT is key context for the $730.8 million complex-wide figure. One session’s total can mask different outcomes among individual issuers, and the September 3 data indicate the largest contribution came from a single product. The outlet also notes that the tracker reports net creations and redemptions once per U.S. trading day and that readings may change when late reports are incorporated.

How the tracker frames the data

As described in the article, the tracker covers daily creations and redemptions, total net assets, Bitcoin held in trust, and any premium or discount to net asset value. It cautions that a dash can indicate a fund has not yet reported rather than a true zero.
