Bitcoin ETF News: Recent Daily Flow Data
ETF flows just flipped from red to green, and one fund is soaking up nearly all of it.
Farside Investors reported positive total net inflows on 6 straight trading days: $297.5 million on August 17, $189.3 million on August 18, $517.2 million on August 19, $606.3 million on August 20, $307.5 million on August 21, and $337.6 million on August 24.
IBIT dominated that entire run. The fund pulled in $160.2 million on August 17, $143.6 million on August 18, $284.7 million on August 19, $503.0 million on August 20, $239.3 million on August 21, and $208.9 million on August 24. Based on the Farside totals, IBIT’s share of daily inflows ranged from 54% to 83% across those 6 sessions.

The turnaround follows a rough stretch earlier in the month. Farside reported total category outflows of $61.1 million on August 12, $131.1 million on August 13, and $56.2 million on August 14. IBIT alone bled 224.94 BTC on August 12, 89.83 BTC on August 13, and 874.61 BTC on August 14.
IBIT now sits at $59.09 billion in assets under management with a 0.25% expense ratio. Its August 24 update showed a price of $44.735 per share across 1.33 billion shares outstanding, with $358.73 thousand in volume and 8,020 shares traded.
The category-wide picture confirms just how top-heavy this market is. IBIT holds a cumulative net inflow of 782,210 BTC and $59.09 billion in AUM. Fidelity’s FBTC follows with 185,610 BTC and $11.22 billion.
Grayscale’s original GBTC has bled 447,280 BTC and sits at $10.35 billion. Grayscale’s Mini Trust holds 34,760 BTC and $4.12 billion. Bitwise’s BITB holds 41,500 BTC and $2.99 billion. ARK’s ARKB holds 40,140 BTC and $2.70 billion.
Dividing IBIT’s $59.09 billion in AUM by the $79.16 billion total net assets across the spot Bitcoin ETF category puts BlackRock’s share at approximately 74.6%. That is the basis for describing IBIT as controlling roughly 75% of the entire spot Bitcoin ETF market.
August 20 Flow Concentration
On August 20, Farside Investors reported $606.3 million in total net inflows for US spot Bitcoin ETFs. IBIT accounted for $503.0 million, while FBTC added $64.7 million, BITB added $26.4 million, ARKB added $12.2 million, and BTCO added $3.6 million. HODL recorded a $3.6 million outflow, according to the same table.
HedgeCo.Net described the August 20 figure as a creation-unit print and noted that IBIT’s share reflected BlackRock winning the creation process that day rather than broad-based sponsorship across the tracked ETF complex. The report also cautioned against treating several positive flow sessions as a lasting commitment from allocators.

The Bottom Line
IBIT’s $208.9 million net inflow on August 24 represented about 62% of the $337.6 million total reported by Farside Investors. CoinGlass’s BTC-denominated data similarly showed IBIT adding 2,690 BTC of the day’s 4,340 BTC total net inflow.
The August 24 result followed several positive sessions for the tracked spot Bitcoin ETF category, while the data also show negative flows on August 12 through August 14.
