Bitcoin ETF inflow streak reaches eight sessions and $2.8 billion

U.S. spot bitcoin exchange-traded funds recorded $232.2 million of net inflows for the Aug. 26 trading session, extending their run of positive sessions to eight, according to Farside Investors’ issuer-level dataset.

Coinburn calculates that the funds attracted approximately $2.80 billion from Aug. 17 through Aug. 26, excluding the intervening weekends. The sequence matters because it shows continued demand through regulated products after bitcoin’s rapid August rebound, rather than a single exceptional subscription day.

It does not prove that ETF demand caused bitcoin’s rally, however. Crypto trades continuously across global venues, while the funds issue and redeem shares during U.S. market sessions. Fund creations can also reflect portfolio transfers or other market-making activity rather than entirely new money entering bitcoin.

BlackRock dominated the inflows

BlackRock’s iShares Bitcoin Trust, or IBIT, supplied $200.8 million of the latest session’s net inflow. Fidelity’s FBTC added $25.6 million and Bitwise’s BITB added $6 million. Morgan Stanley’s MSBT and Grayscale’s lower-fee Bitcoin Mini Trust contributed $3.4 million and $46.8 million, respectively, while Grayscale’s older GBTC product posted a $50.4 million outflow.

Across all eight sessions, Coinburn’s calculation from Farside’s daily rows puts IBIT’s net inflow at approximately $2.02 billion, or 72.3% of the $2.80 billion total. That concentration is important: the streak represents demand for the overall product category, but most of the recorded dollars passed through one fund.

BlackRock’s own product page listed IBIT at approximately $60.52 billion in net assets as of Aug. 26. It also reported a $44.46 closing share price and 42.85 million shares of daily trading volume for that date. Trading volume measures shares changing hands and should not be confused with net creations, fund inflows or purchases of bitcoin.

Bitcoin’s benchmark recovered, but the window is narrow

The CME CF Bitcoin Reference Rate was $79,900.28 at 3 p.m. GMT on Aug. 27, up 2.11% from its preceding daily reference value. The instrument is the BRR, a once-daily U.S.-dollar benchmark aggregating transactions from qualifying bitcoin-dollar markets; it is not a continuous spot quote and may differ from prices displayed on individual exchanges before or after its calculation window.

That distinction also separates the timelines. The latest completed ETF-flow observation covers the Aug. 26 U.S. trading session. Farside displayed the finalized issuer rows on Aug. 27. The cited bitcoin benchmark belongs to Aug. 27 at 3 p.m. GMT, while Coinburn’s edition date is Aug. 27 in America/New_York. No claim is being made that all ETF subscriptions occurred at the cited benchmark price.

What the streak establishes

The verified conclusion is limited but significant: net creations remained positive for eight consecutive U.S. trading sessions, and the cumulative amount was large enough to show persistent demand through listed products. The Aug. 26 total was lower than the $314.3 million recorded on Aug. 25 and the $337.6 million recorded on Aug. 24, but it remained positive despite GBTC’s outflow.

The figures do not establish the identity or motivation of the underlying buyers. They also cannot determine how much bitcoin authorized participants acquired on the open market, because creation mechanics, inventory and timing vary. Farside describes its table as automatically generated and warns that it may contain errors or later revisions.

The next test is whether the streak continues after Aug. 26 and whether demand broadens beyond IBIT. Finalized issuer-level rows, rather than early estimates or ETF trading volume, will determine that answer.
