BlackRock's IBIT Pulls In $479M as U.S. Spot Bitcoin ETFs Log Five Straight Days of Inflows

U.S. spot bitcoin ETFs took in $98.85 million on Aug. 7, extending their net-inflow run to five consecutive trading sessions. Spot ether ETFs added another $49.60 million the same day, marking a fourth straight day of gains. The latest figures push weekly inflows into spot bitcoin ETFs above $750 million, a turnaround from the choppy, start-and-stop flow pattern that characterized much of the year. The current streak began Monday, Aug. 3, and has continued through Friday without a single net-outflow day. By contrast, Solana and XRP ETF products showed essentially no net change on Aug. 7. BlackRock's iShares Bitcoin Trust (IBIT) has been the primary driver. From Monday through Wednesday, IBIT accounted for $479 million of the $626 million total that entered spot bitcoin ETFs, roughly 76% of the three-day intake. Over that same period, Fidelity's FBTC drew $19.6 million, ARK 21Shares' ARKB took in $9.2 million, and Bitwise's BITB added $8.7 million. Grayscale's GBTC, the legacy product converted to an ETF in early 2024, has now posted cumulative net outflows of $27.47 billion since conversion. Ether ETF flows have followed a similar template, with BlackRock dominating daily totals. On Aug. 5, spot ether ETFs recorded $60.86 million in net inflows, including $50.34 million into BlackRock's ETHA, about 83% of the day's total. Fidelity's FETH added $2.87 million, while Bitwise's ETHW and 21Shares' TETH each brought in about $1.3 million. BlackRock's staked-ether product, ETHB, attracted an additional $4.94 million on top of ETHA's intake. The concentration means the four-day streak in ether ETFs is largely a BlackRock-led move layered on top of renewed demand for bitcoin exposure. Smaller issuers are posting inflows, but volumes are modest enough that a single large BlackRock allocation can swing the category's daily result. The rebound follows a difficult stretch: spot bitcoin ETFs logged $5.4 billion in net outflows in the first half of 2026, the first negative half-year since launch in early 2024. July briefly delivered a seven-session inflow run that brought in nearly $1 billion, then reversed on July 24 with a $225.18 million single-day outflow before buyers returned in early August. Several factors appear to be supporting the renewed bid. Franklin Templeton has highlighted the prospect of federal crypto market-structure legislation as a potential catalyst, arguing it could eventually allow bank balance-sheet liquidity to enter the asset class more directly. Separately, weaker U.S. jobs data this week reinforced expectations for rate cuts, lifting risk appetite across equities and crypto; the S&P 500 ended the week at a record high as ETF inflows improved. Whether the momentum carries into a second week may hinge on whether BlackRock's allocations remain steady after the current wave of institutional rebalancing fades. Five consecutive inflow days is longer than anything U.S. spot bitcoin ETFs achieved in late July, though flows have alternated between multi-week runs and abrupt reversals throughout the year.
