U.S.-listed spot Bitcoin ETF recorded a net inflow of roughly $338 million on Monday, extending their winning streak to six consecutive trading days. The latest inflow brings the combined haul across the six-session stretch from Aug. 17 through Aug. 24 to $2.26 billion.
Total net assets across the category have also climbed to about $98.6 billion, while cumulative net inflows since the funds launched in January 2024 reached $54.0 billion.

BlackRock’s iShares Bitcoin Trust, or IBIT, remains the dominant force behind the inflow streak. IBIT attracted another $209 million on Aug. 24, taking its six-session intake to roughly $1.54 billion. This represents about 68% of the $2.26 billion flowing into U.S. spot Bitcoin ETFs since last week, reinforcing its position as the leading institutional vehicle for regulated Bitcoin exposure.
That concentration remains important as Bitcoin pushes toward the $80,000 level. The latest ETF demand suggests institutional appetite has not faded after last week’s sharp rally, although the pace of inflows will now be tested as the market moves beyond the initial surge.
Bitcoin ETF assets also jumped sharply alongside the price rally, meaning part of the increase in assets reflects Bitcoin’s appreciation rather than fresh capital alone.

Bitcoin ETF Inflows: What the $1.9B Streak Shows
The six-day run breaks down unevenly by session. On Aug. 17, total net inflows of $297.5 million included $160.2 million from IBIT, about 54% of that day’s total. Aug. 18 brought a smaller overall total of $189.3 million, but IBIT’s $143.6 million share climbed to roughly 76%.
Aug. 19 saw the category’s biggest single-day print at that point, $517.2 million, with IBIT contributing $284.7 million, or about 55%. Aug. 20 was the standout session: total inflows jumped to $606.3 million, and IBIT alone brought in $503.0 million, an 83% share.
Fidelity’s FBTC added $64.7 million, Bitwise’s BITB brought in $26.4 million, ARK 21Shares’ ARKB contributed $12.2 million, and Invesco Galaxy’s BTCO added $3.6 million, while VanEck’s HODL posted a $3.6 million outflow.

Friday’s close, Aug. 21, added another $307.5 million, with IBIT’s $239.3 million representing about 78% of that session. The momentum continued on Monday, Aug. 24, when spot Bitcoin ETFs recorded another $337.6 million in net inflows.
IBIT led again with $209 million, while FBTC added $105 million. That pushed the six-session total from Aug. 17 through Aug. 24 to roughly $2.26 billion, extending the category’s inflow streak to six consecutive trading days.
The available data show that while other funds, particularly FBTC, BITB, and ARKB, also registered positive days during the streak, none approached IBIT’s cumulative scale. IBIT accounted for roughly $1.54 billion of the $2.26 billion flowing into U.S. spot Bitcoin ETFs across the six sessions, or about 68%.
The concentration highlights just how much fresh institutional demand is currently routed through BlackRock’s wrapper rather than being distributed evenly across the roughly dozen products now trading.

Why BlackRock’s IBIT Is Driving Institutional Bitcoin Demand
IBIT’s dominance matters because of what it represents structurally. As a regulated, exchange-traded product, IBIT gives pensions, RIAs, and traditional brokerage accounts a way to gain Bitcoin exposure without touching a crypto exchange, a self-custody wallet, or a futures account.
According to CoinMarketCap Academy’s reporting on the broader Bitcoin ETF complex, IBIT has held 809,870 BTC, representing more than 60% of assets under management across the spot Bitcoin ETF category.

Prior coverage of BlackRock-led ETF demand has tracked this build-up as it accumulated over multiple quarters.
Creation-unit flows into IBIT and its peers represent actual dollars converted into custodied Bitcoin through an authorized-participant process, a different mechanism from short covering on derivatives exchanges or leveraged futures positioning, which can reverse in hours.
A five-day stretch of $1.9 billion in net creations is a signal of allocators putting new capital to work, not traders unwinding bearish bets.
That said, the same concentration that makes IBIT the most visible gauge of institutional demand also concentrates risk. A market where roughly 69% of new flows run through a single issuer, custodian, and product structure is more fragile to idiosyncratic shocks
